Email is the single account that unlocks every other account. Reset your bank, your crypto exchange, your work login, and the verification link lands in one inbox. That makes the choice between Proton Mail vs Gmail less about which app looks nicer and more about who can read your most sensitive messages, and under which country’s laws. In 2026 the two services sit at opposite ends of that spectrum. Gmail holds roughly 29% of the global email client market and ships Google’s Gemini AI inside the inbox. Proton Mail runs a zero-access encryption model from Switzerland, where the provider cannot read your mailbox even if it wanted to.

This comparison runs both services through a 14-row spec table, full pricing for every tier, encryption internals, independent audit results, five real migration scenarios, and a step-by-step switch guide. By the end you will know which inbox fits a privacy-first activist, a five-person startup, a family of four, and an AI-heavy power user. The short version: Gmail wins on storage, integration, and AI, while Proton Mail wins on confidentiality, jurisdiction, and the simple promise that nobody at the company can open your mail.

Proton Mail vs Gmail: The 30-Second Verdict

Pick Proton Mail if confidentiality is the priority. It uses end-to-end encryption between Proton users, a zero-access architecture so Proton itself cannot decrypt your stored mail, Swiss jurisdiction outside US and EU data-sharing frameworks, and a no-ads business model funded by subscriptions rather than data. The cost: 1 GB of free storage, weaker third-party app integration, and AI tooling that is deliberately limited.

Pick Gmail if convenience, storage, and AI matter most. The free tier gives 15 GB shared across Gmail, Drive, and Photos, deep integration with Docs, Calendar, Meet, and Android, plus Gemini AI for drafting and summarizing. The trade-off: Google can technically access content for service operation, the model is ad-adjacent, and your mail sits under US jurisdiction. For most people the honest answer is “both”, Gmail for shopping receipts and newsletters, Proton Mail for anything you would not want a stranger reading.

If you need a refresher on what encryption in transit actually protects, our explainer on HTTPS and TLS covers the padlock that Gmail relies on for messages crossing the wire.

Proton Mail vs Gmail Pricing: Every Tier Compared

Pricing is where the two services stop being comparable products and become different categories. Gmail is free and bundles storage with the rest of Google. Proton charges for the mailbox itself. The table below shows annual-billing prices, which are the rates most users actually pay.

PlanPrice (annual billing)StorageBest for
Proton Free$01 GBTrying zero-access mail
Proton Mail Plus$3.99/mo15 GBOne private inbox + custom domain
Proton Unlimited$9.99/mo500 GBPower users wanting all Proton apps
Proton Duo$14.99/mo2 TB sharedCouples, two users
Proton Family$23.99/mo3 TB sharedUp to 6 family members
Gmail Free$015 GB sharedEveryday personal email
Google One 100 GB$1.99/mo100 GBHitting the 15 GB ceiling
Google One 2 TB$9.99/mo2 TBPhotos and Drive heavy users

Workspace Business Standard$14.40/user/mo2 TB/userGrowing teams, Gemini included
Workspace Business Plus$21.60/user/mo5 TB/userCompliance, larger teams

Read the pricing carefully. Proton Mail Plus at $3.99 a month buys you a single encrypted mailbox with a custom domain, the closest direct rival to a personal Gmail with extras. Google’s cheapest paid step, Google One 100 GB at $1.99 a month, buys storage, not privacy: your mail stays as readable to Google as it was on the free tier. For business, Workspace Business Standard at $14.40 per user undercuts most expectations and bundles Gemini, while Proton’s per-seat business pricing trades that AI for confidentiality. The pattern mirrors what we found comparing Bitwarden vs 1Password: the privacy-first option often costs less than people assume, because it is not subsidizing a data-driven ad engine.

Encryption Deep Dive: Zero-Access vs TLS

This is the section that should drive your decision. The two services protect mail in fundamentally different ways, and the marketing language (“encrypted”) hides a gap wide enough to drive a subpoena through.

How Proton Mail Encrypts

Proton Mail uses two layers. First, end-to-end encryption applies when both sender and recipient use Proton or exchange PGP keys: the message is encrypted on your device and only decrypted on theirs, so it never exists in readable form on Proton’s servers. Second, zero-access encryption protects everything else in your mailbox at rest. When a non-Proton sender emails you, the message arrives over TLS, then Proton encrypts it with your public key before storing it. The private key that decrypts it is itself locked behind your password, which Proton never sees. The practical result: a Proton engineer, a hacker who breaches the data center, or a government with a Swiss court order cannot hand over readable mail, because the provider does not hold the keys.

Proton also supports password-protected emails to non-Proton recipients. You set a password out of band, the recipient enters it on a Proton page, and the message decrypts in their browser. This extends end-to-end protection to anyone with any email address. The underlying cryptography uses OpenPGP with elliptic-curve and RSA keys, the same family of primitives we break down in our guide to digital signatures.

How Gmail Encrypts

Gmail encrypts mail in transit with TLS, so messages between Gmail and other TLS-capable servers are protected on the wire. At rest, Google encrypts data on its disks, but Google holds those keys. That means Gmail content is decryptable by Google for spam filtering, search indexing, Smart Compose, and, when legally compelled, for law enforcement. Gmail’s Confidential Mode adds expiration dates and blocks forwarding, but it is not end-to-end encryption: Google can still read those messages. Client-side encryption exists, but only inside Google Workspace Enterprise plans with customer-managed keys, not for ordinary consumer Gmail.

The difference matters in one specific scenario: when someone with legal or illicit access wants to read your stored mail. With Gmail, the data exists in a form Google can decrypt. With Proton, it does not. For threat models that include subpoenas, insider risk, or server breaches, that is the whole game. For a threat model of “I just don’t want my inbox hacked,” both services do well if you enable strong authentication, which brings us to the next section.

Privacy and Jurisdiction: Switzerland vs the United States

Encryption is only half the privacy story. The other half is the law that governs the company. Proton is headquartered in Geneva and operates under Swiss data-protection law, which sits outside the EU and the United States. Switzerland is not part of the so-called Five Eyes, Nine Eyes, or Fourteen Eyes intelligence-sharing alliances. Swiss law requires a Swiss court order before a provider must respond to a data request, and even then, Proton can only hand over the encrypted blob it stores plus limited metadata, because it lacks the keys to your content.

Google is a US company subject to US legal process, including National Security Letters and the CLOUD Act, which can compel disclosure of data stored anywhere in the world. Google publishes transparency reports showing tens of thousands of government data requests per reporting period, and because Gmail content is decryptable by Google, those requests can yield readable mail. None of this is a Google scandal; it is the structural reality of a US provider that holds your keys.

One honest caveat about Proton: zero-access protects content, not all metadata. Proton still processes sender, recipient, and timestamps to deliver mail, and it has complied with valid Swiss legal orders for metadata in documented cases. The Electronic Frontier Foundation has long stressed that metadata can be as revealing as content. If your threat model includes who-talked-to-whom analysis, no email provider fully solves that; tools like the messengers in our Signal vs WhatsApp vs Telegram comparison handle metadata more aggressively than any email service can.

Storage: Why 1 GB vs 15 GB Is Not the Whole Story

On paper Gmail crushes Proton on free storage, 15 GB to 1 GB. In practice the comparison is messier. Gmail’s 15 GB is shared across Gmail, Google Drive, and Google Photos, so a few years of high-resolution photo backups can swallow the entire allowance and start choking your inbox. Many Gmail users discover the 15 GB ceiling not through email but through Photos, then pay for Google One to keep both working.

Proton’s 1 GB free tier is genuinely tight for email and is best understood as a trial rather than a permanent home. The moment you go paid, the math flips: Proton Mail Plus gives 15 GB for mail at $3.99 a month, Proton Unlimited gives 500 GB plus the full suite of Proton Drive, VPN, Pass, and Calendar at $9.99 a month. Google One 2 TB also costs $9.99 a month but adds storage to a non-encrypted ecosystem. For users who store sensitive documents, Proton Unlimited’s 500 GB of encrypted Drive storage often delivers more real privacy per dollar than raw Google capacity, the same value logic that drives people toward encrypted alternatives after reading about how data breaches happen.

Security Features: 2FA, Passkeys, and Account Recovery

Both services offer strong account security, and the gap here is smaller than the encryption gap. Both support two-factor authentication via authenticator apps and hardware security keys, and both have rolled out passkey support during the 2025 to 2026 product cycle. Passkeys remove the password from the login flow entirely, which matters because stolen passwords remain the top breach vector, as our breakdown of passkeys vs passwords documents in detail.

The interesting divergence is account recovery, and it cuts against Proton. Because Proton cannot read your mailbox, it also cannot reset your way back into encrypted data if you lose your password and recovery phrase. Lose both and the mail is gone, permanently. This is the unavoidable cost of zero-access: there is no support agent who can let you back in, because there is no master key. Google, by contrast, can recover most locked accounts through phone, backup email, and identity checks, precisely because it controls the keys. Convenience and confidentiality pull in opposite directions, and recovery is where you feel it.

Google One paid tiers also bundle dark web monitoring that alerts you when your address surfaces in a breach dump, a useful feature given that infostealer malware harvested over 1.8 billion credentials in 2025, as covered in our report on infostealer malware. Proton offers a comparable breach-alert feature through Proton Pass and its monitoring tools. Whichever you choose, turn on hardware-key or passkey 2FA before you do anything else.

AI Features: Gemini vs Proton’s Privacy-First Approach

AI is the fastest-moving front in this comparison, and the two companies have taken philosophically opposite paths. Google embeds Gemini across Gmail: it drafts replies, summarizes long threads, searches your mailbox in natural language, and surfaces information from across Workspace. On paid Google One AI and Workspace plans, Gemini becomes a genuine inbox copilot. The cost is conceptual: to be helpful, the model reads your mail.

Proton built its AI to never see your mail in a way the company can exploit. Proton Scribe is a writing assistant that can run locally or on Proton’s no-logs infrastructure, and Proton’s standalone assistant Lumo is designed so chats stay private and are not used to train models. Proton’s public stance is blunt: it does not train AI on user email. The result is less capable assistance than Gemini but a guarantee that your draft about a medical diagnosis or a legal dispute is not feeding a model. If you want maximum AI productivity, Gmail wins clearly. If you want AI that respects the confidentiality of the data it touches, Proton’s approach is the only one of the two that makes that promise.

Benchmarks From Independent Reviewers and Audits

Email is hard to benchmark like a CPU, so the meaningful data points are independent audits, reviewer scores, and verifiable claims. Three sources frame the picture.

Source / MetricProton MailGmail
Independent security auditSecuritum third-party audits of appsSOC 2 / ISO internal compliance
Open-source clientsYes, code public for reviewNo, closed source
Email client market share (2026)Under 2%~29%
Reviewer privacy ratingTop-tier across PCMag, TechRadarMid-tier on privacy axis
Reviewer features/ecosystem ratingMid-tier (limited integrations)Top-tier (deep integration)
Spam filtering qualityStrongIndustry-leading

Three takeaways. First, Proton’s open-source clients and Securitum audits mean its encryption claims are externally verifiable, a standard Gmail does not meet because its code is closed. Second, Gmail’s spam filtering, built on Google’s vast signal data, remains the best in the industry, and Proton, while strong, cannot match that scale. Third, reviewer consensus across outlets like PCMag and TechRadar consistently rates Proton highest on privacy and Gmail highest on ecosystem and AI, which is exactly the trade this whole article describes. There is no benchmark that crowns one winner, because the two optimize for different things.

5 Real-World Scenarios: Which Inbox Wins

Abstract specs only get you so far. Here is how the choice plays out in five concrete situations.

1. The journalist protecting a source. A reporter exchanging documents with a whistleblower needs content that no provider can be compelled to surrender. Proton Mail wins decisively: zero-access storage plus Swiss jurisdiction means a US subpoena lands on a company that cannot decrypt the mail. Gmail here is a liability.

2. The five-person SaaS startup. A small team needs shared calendars, video calls, document collaboration, and custom-domain email at a predictable per-seat cost. Google Workspace Business Standard at $14.40 per user bundles all of it plus Gemini. Proton’s business tier protects content but forces the team to stitch together more tools. Gmail wins on operational gravity.

3. The family of four. Parents want one bill, shared storage, and protection for kids’ accounts. Proton Family at $23.99 a month covers up to six members with 3 TB of encrypted storage across Mail, Drive, VPN, and Pass. Google One family sharing is cheaper for raw storage but offers no zero-access guarantee. For privacy-conscious parents, Proton wins; for budget-first families already in the Google ecosystem, Gmail plus Google One wins.

4. The crypto holder. Anyone managing self-custodied assets treats email as the recovery path for exchanges and the target of phishing. Proton’s encryption and anti-phishing posture, paired with hardware-key 2FA, reduces the attack surface around account resets. This is the same defensive mindset that drives privacy-tooling choices in our NordVPN vs Surfshark comparison. Proton wins for high-value targets.

5. The everyday user with 50,000 emails. Someone with a decade of Gmail history, Android phone, YouTube, Maps, and Photos all tied to one account faces enormous switching friction. The pragmatic move is not a full migration but a split: keep Gmail for low-sensitivity mail, open Proton for banking, health, legal, and identity. Most real users land here, and it is a legitimate answer rather than a cop-out.

Use-Case Recommendations: 6 Profiles

  • Privacy-first individual: Proton Mail Plus ($3.99/mo). Custom domain, 15 GB, zero-access mail, no ads.
  • All-in power user: Proton Unlimited ($9.99/mo). 500 GB plus Mail, VPN, Drive, Pass, and Calendar in one bill.
  • Small business needing AI and collaboration: Google Workspace Business Standard ($14.40/user/mo). Gemini, 2 TB per user, Meet, Docs.
  • Privacy-conscious small business: Proton for Business. Encrypted mail with custom domain, fewer integrations but real confidentiality.
  • Budget user already in Google’s ecosystem: Gmail free, add Google One 100 GB ($1.99/mo) when storage fills. Cheapest path, weakest privacy.
  • Family wanting privacy under one bill: Proton Family ($23.99/mo) for six members and 3 TB encrypted storage.

Migration Guide: Moving From Gmail to Proton Mail

Switching does not have to mean abandoning your old address overnight. Proton’s Easy Switch tool automates most of the work. Here is the sequence that minimizes broken logins and lost mail.

  1. Create your Proton account and pick a plan. Start with Mail Plus if you want a custom domain immediately, or Free to test.
  2. Run Proton Easy Switch. In Proton Mail settings, connect your Gmail account and let the importer copy existing mail, contacts, and calendar events. Large mailboxes can take hours; let it finish in the background.
  3. Set up forwarding in Gmail. In Gmail settings, forward incoming mail to your Proton address so nothing is missed during the transition.
  4. Update your critical accounts. Change the email on banking, crypto, password manager, and identity accounts first. Use a password manager to find every account tied to the old address.
  5. Configure your custom domain (optional). Add DNS records (MX, SPF, DKIM, DMARC) in your registrar so mail flows to Proton and passes spam checks.
  6. Enable 2FA and save your recovery phrase. This is non-negotiable on Proton: write down the recovery phrase and store it offline, because Proton cannot recover a lost account.
  7. Run both inboxes in parallel for 60 to 90 days. Watch what still arrives at Gmail, migrate stragglers, then reduce Gmail to a forwarding-only fallback.

The single most common migration mistake is updating your email everywhere except the one account that matters, then losing access during a reset. Inventory first, migrate critical accounts second, and never delete the Gmail account until you have confirmed every service points to Proton. If you maintain a custom domain, your address becomes portable forever, which is the strongest reason to set one up during the move rather than later.

Proton Mail Pros and Cons

Pros: Zero-access and end-to-end encryption mean Proton cannot read your mail. Swiss jurisdiction sits outside major intelligence-sharing alliances. All clients are open source and independently audited by Securitum. No ads, no data-driven business model. Built-in PGP and password-protected email extend privacy to any recipient. Unlimited plan bundles VPN, Drive, Pass, and Calendar.

Cons: Only 1 GB of free storage. No master-key account recovery, so a lost password plus lost recovery phrase means permanent data loss. Weaker third-party app integration than Google. AI features are deliberately limited compared to Gemini. End-to-end encryption only reaches its full strength when the recipient also uses Proton or PGP. Smaller spam-signal pool than Google.

Gmail Pros and Cons

Pros: 15 GB free storage shared across a vast ecosystem. Industry-leading spam filtering. Deep integration with Docs, Calendar, Meet, Drive, Android, and the rest of Google. Gemini AI for drafting, summarizing, and searching. Reliable account recovery. Massive third-party app support. Effectively free for most personal use.

Cons: Google can read mail content at rest, by design. US jurisdiction exposes data to broad legal process including the CLOUD Act. No end-to-end encryption for consumer accounts. Closed-source clients cannot be externally verified. The 15 GB free tier fills fast once Photos and Drive are counted. AI helpfulness depends on the model reading your inbox.

Apps and User Experience: Web, Mobile, Desktop

Daily usability decides whether a privacy upgrade actually sticks. Gmail has a decade-plus head start here, and it shows. The Gmail web client is fast, search is instant across an enormous mailbox, and the Android and iOS apps are among the most polished email clients shipping. Smart features like nudges, snoozing, and Smart Compose are mature, and the integration with Google Contacts and Calendar is seamless because they are the same product family.

Proton Mail has closed much of the experience gap over the 2024 to 2026 cycle. The redesigned web app, native desktop apps for Windows, macOS, and Linux, and the mobile apps now feel competitive rather than compromise. Search has improved with on-device indexing, which is the privacy-correct way to make encrypted mail searchable: the index lives on your machine, not on Proton’s servers. The honest gap remaining is breadth of third-party integration. If a tool offers a “Sign in with Google” button or a Gmail plugin, it rarely offers a Proton equivalent. For users whose workflows depend on those integrations, that friction is real and worth testing during a trial period.

Mobile appsiOS, Android (improving fast)iOS, Android (best in class)
Offline accessLimitedRobust offline mode
Third-party integrationsNarrowVast
Bridge for IMAP clientsYes (Proton Bridge, paid)Native IMAP/POP

One Proton feature deserves a callout: Proton Bridge. It runs locally, decrypts mail on your device, and exposes a standard IMAP/SMTP interface so you can use Proton inside Thunderbird, Outlook, or Apple Mail without breaking encryption. Gmail supports IMAP and POP natively because there is no end-to-end encryption to preserve. Both reach the same destination of “use my desktop client,” but Proton has to do clever local work to get there without surrendering its security model.

Deliverability and Spam Filtering Compared

Deliverability is the unglamorous metric that breaks more setups than any encryption debate. Gmail benefits from operating at planetary scale: its spam classifier trains on signals from billions of messages a day, which is why Gmail’s spam folder is famously accurate and false positives are rare. Outbound deliverability from Gmail is also near-universal because receiving servers trust Google’s IP reputation.

Proton’s spam filtering is genuinely strong, but it cannot match Google’s signal volume, and that occasionally shows in edge cases. The bigger deliverability consideration with Proton arrives when you bring a custom domain. You must configure SPF, DKIM, and DMARC records correctly, or your outbound mail can land in recipients’ spam folders. Proton’s setup wizard walks you through it, but the responsibility shifts to you in a way it never does on a stock Gmail address. For businesses, getting DMARC right is not optional; it is the difference between invoices that arrive and invoices that vanish. The same authentication discipline underpins trustworthy web connections, which our TLS explainer covers from the transport side.

Ecosystem and Integrations: Calendar, Drive, and Beyond

Neither service is just email anymore, and the surrounding ecosystem often decides the choice. Google’s suite is the deepest in consumer software: Gmail sits beside Docs, Sheets, Slides, Drive, Calendar, Meet, Keep, and Photos, all sharing one login and one storage pool. For collaboration, real-time document editing, and video meetings, nothing in the privacy world matches Workspace’s polish or network effects.

Proton has built a parallel, encrypted ecosystem that did not exist a few years ago. A Proton Unlimited subscription includes Proton Mail, Proton Calendar (end-to-end encrypted), Proton Drive (encrypted file storage and sync), Proton VPN (a no-logs VPN with audited apps), Proton Pass (a password manager with passkey support), and Proton Wallet. The pitch is a privacy-respecting alternative to the entire Google stack under one bill. The reality is that each Proton app is good but not yet as feature-rich as its Google counterpart, and collaboration features lag. The trade is consistent with everything else in this comparison: you exchange some capability and convenience for confidentiality and a vendor that does not monetize your data. For users assembling a privacy toolkit, pairing Proton with a dedicated password manager and VPN is common, and our password manager comparison helps round out that stack.

What Security Experts Say

The professional consensus is not “Proton good, Gmail bad.” It is “match the tool to the threat model.” Privacy advocates, including the Electronic Frontier Foundation, have argued for years that end-to-end encryption should be the default and that metadata exposure is the harder, unsolved problem. That framing favors Proton’s architecture while acknowledging its limits.

Edward Snowden, whose disclosures reshaped how the public thinks about email surveillance, has publicly championed end-to-end encrypted tools and steering sensitive communication away from US-jurisdiction providers that hold user keys. Mainstream reviewers land in a more balanced place: PCMag and TechRadar repeatedly rate Proton Mail as a top choice for privacy while rating Gmail highest for everyday convenience, AI, and ecosystem depth. The recurring expert advice is practical rather than tribal: use Gmail for the low-stakes flood of receipts and newsletters, and route anything you would not want read in open court through an encrypted, audited provider like Proton. Security researchers also stress the boring fundamentals that beat any provider choice, the same ones in our authentication guidance: turn on hardware-key 2FA, use a password manager, and never reuse credentials.

Final Verdict: Proton Mail vs Gmail in 2026

The data points to a clean split rather than a knockout. Proton Mail wins on privacy: zero-access encryption, Swiss jurisdiction, open-source audited clients, and a business model that does not monetize your data. Gmail wins on capability: 15 GB free, best-in-class spam filtering, Gemini AI, and an ecosystem so deep that leaving it is a project, not a click.

For a single, definitive recommendation: if you are choosing a primary inbox today and privacy ranks anywhere in your top three priorities, start moving to Proton Mail Plus at $3.99 a month, secure a custom domain so your address is portable forever, and keep Gmail as a forwarding fallback for low-sensitivity mail. If privacy is not a meaningful concern and you live inside Google’s tools, Gmail remains the most capable free inbox on the planet, and Google Workspace Business Standard is the strongest small-team value. The worst choice is the unexamined one: treating the account that controls every password reset you own as an afterthought. Pick deliberately, turn on 2FA, and write down your recovery phrase.

Frequently Asked Questions

Is Proton Mail safer than Gmail?

For confidentiality, yes. Proton Mail uses zero-access encryption so the provider cannot read your stored mail, and it operates under Swiss law outside major intelligence-sharing alliances. Gmail encrypts mail in transit but keeps content readable by Google at rest. For raw account-takeover defense, both are strong if you enable hardware-key or passkey 2FA. The safety advantage Proton offers is specifically against the provider, breaches of stored data, and legal compulsion.

Is Proton Mail free, and what are the limits?

Yes, Proton Mail has a free tier, but it includes only 1 GB of storage, one address, and limited features. It is best treated as a trial of the zero-access model. Paid plans start at Mail Plus for $3.99 a month (annual billing) with 15 GB and custom-domain support. Gmail’s free tier is more generous at 15 GB, but that storage is shared with Drive and Photos.

Can I use a custom domain with Proton Mail or Gmail?

Proton supports custom domains on paid personal plans starting with Mail Plus. Gmail supports custom domains only through Google Workspace, not on free consumer Gmail. A custom domain is worth setting up during migration because it makes your address portable: you can change providers later without changing your email.

Does Proton Mail or Gmail read my email for AI?

Gmail’s Gemini features read your mail to draft, summarize, and search, which is how they provide assistance. Proton states it does not train AI on user email, and its assistant tools are built to keep content private and unlogged. If you want powerful AI inside the inbox, Gmail leads. If you want AI that does not exploit your mail’s contents, Proton’s approach is the more conservative choice.

What happens if I lose my Proton Mail password?

Because Proton cannot access your encrypted mailbox, losing both your password and your recovery phrase means permanent loss of access to that encrypted data. This is the unavoidable trade-off of zero-access encryption. Save your recovery phrase offline when you create the account. Gmail, by contrast, can recover most locked accounts through identity verification, because Google holds the keys.

Should I switch from Gmail to Proton Mail completely?

For most people, a full switch is unnecessary and risky given how many services tie to a Gmail address. The pragmatic approach is a split: open Proton for banking, health, legal, identity, and any sensitive correspondence, while keeping Gmail for newsletters, shopping, and low-stakes mail. Migrate critical accounts to Proton first, run both in parallel for a few months, and only then decide whether to reduce Gmail to a fallback.

Is Proton Mail’s encryption independently verified?

Yes. Proton’s client applications are open source, meaning anyone can inspect the code, and Proton has commissioned independent security audits from the firm Securitum. Gmail’s clients are closed source and rely on internal compliance certifications rather than public, third-party code review of its encryption.

How do you protect against phishing on either service?

Both services filter phishing, with Gmail’s filters benefiting from Google’s enormous signal pool. Regardless of provider, enable hardware-key or passkey 2FA, never enter credentials from an email link, and verify sender domains carefully. Our guide on recognizing phishing attacks walks through the warning signs that no spam filter catches every time.
