Proton Mail vs Gmail: Which Is Better in 2026?

Try Proton Mail freeAffiliate link · how it works →

A note on how this page was built. Proton has an affiliate program that this site may join, and I opened a free Proton Mail account on 10/09/2026. Google has no program in our route, and this site has no Gmail test account.

So Proton gets the buttons, and Gmail’s column comes from Google’s own help center, privacy policy, and pricing pages, read on 10/16/2026. That doesn’t change the facts below.

Prices verified on 10/16/2026 on Proton’s site. Google One prices are from the Wayback Machine copy of Google’s plans page dated 10/12/2026, because Google showed our connection Australian dollars on 10/16/2026.

Privacy: who can read your mail

This is the main difference. Proton’s help center says every message in a Proton inbox is stored with zero-access encryption, so “nobody else can access your emails, not even Proton.” That includes mail that arrives from Gmail or Outlook. Signup asked me for a username and a password, then a human check.

Proton’s privacy policy adds that no personal information is needed to open an account, and that it keeps no permanent IP logs by default. It can log an IP address to fight abuse or when ordered to.

Google works differently. Its privacy policy took effect in a new version on 10/16/2026.

The policy says Google collects “email you write and receive.” It also says automated systems analyze your content to tailor features and ads, and to detect spam and malware. So Google’s systems process what’s in your mail. Proton says it can’t read yours.

On ads, Google drew a line in 2017. A post by Diane Greene on 06/23/2017 said consumer Gmail content “will not be used or scanned for any ads personalization.” Gmail’s help page says the same on 10/16/2026: “Gmail does not scan or read your messages to show you ads.”

Ads still appear in Gmail, based on your activity while signed in to Google, and you can turn off ad personalization. Proton says Proton Mail is funded entirely by paying subscribers, and I saw no ads in my free inbox.

Gmail’s smart features, such as Smart Compose and order tracking cards, use your mail content. Google’s help page says these settings are off by default only in the European Economic Area, Japan, Switzerland, and the United Kingdom. The U.S. isn’t on that list. You can switch them off in Gmail’s settings.

Encryption: end to end or only in transit

Every Gmail message travels with TLS, which protects it between providers that both support it. That’s where a personal account stops. Confidential mode adds an expiry date and a passcode, but Google warns that recipients can still take screenshots. It isn’t encryption.

Client-side encryption, where your organization holds the key, is listed only for Workspace Enterprise Plus, Education Plus, Education Standard, and Frontline Plus. Even there, Google says the subject line and recipients stay outside the extra encryption. The full walkthrough is in how to send encrypted email in Gmail.

Proton encrypts mail between Proton addresses end to end. For anyone else, including a Gmail address, the free plan can send a password-protected email. The recipient opens it in a browser with a password you share another way, and it expires after up to 28 days.

Proton has the same weak spot on subject lines. Its help center says subject lines and sender and recipient addresses aren’t end-to-end encrypted, because the OpenPGP standard keeps them in the header. Write subject lines as if someone else could read them, on either service.

Price and free storage

Gmail is the clear winner on free space. Google’s help center says each Google Account includes up to 15 GB, shared across Gmail, Google Drive, and Google Photos. Proton’s pricing page says “Up to 1 GB” on the free plan. My new free account showed 500 MB, and Proton’s help center says a starter checklist raises it to 1 GB.

Paying for more is cheaper at Google, but you pay for different things. Google One’s 100 GB plan was $1.99 a month or $19.99 a year in the Wayback copy of 10/12/2026. It adds storage, not privacy features.

Proton’s Mail Plus was $3.99 a month billed as $47.88 for 12 months on 10/16/2026, or $4.99 month to month. It adds 15 GB, 10 addresses, one custom domain, unlimited folders, and Bridge for desktop mail apps.

With a New York ZIP, Proton’s checkout added $4.25 tax for $52.13 on 10/09/2026. It said the plan auto-renews but didn’t print the renewal price, and Proton’s terms say renewals cost “the then-current price.” Proton’s row in our US Privacy Checkout Test has the rest. Every Proton plan and price is on the Proton Mail pricing page.

For your own domain on Gmail, you need Google Workspace. Its annual plans listed $7, $14, and $22 per user per month on 10/09/2026, and S/MIME encryption appears only on the Enterprise plan, which has no public price.

Everyday use: apps, search and moving over

Gmail is easier to fit into the rest of your setup. Google’s help center says IMAP is always on, so Outlook, Apple Mail, or Thunderbird can read a free Gmail account. Proton needs its Bridge app for those, and the settings in my free account locked Bridge behind Mail Plus or higher.

Gmail filters can label, archive, delete, star, or forward incoming mail, per Google’s help center. Proton’s free plan allows three folders, three labels, and one filter. Mail Plus lifts those limits.

Search is another trade-off of encryption. Gmail’s search needs no setup and takes operators such as from: or has:attachment, per Google’s help center. Proton can’t read your mail on its servers, so content search builds an encrypted index in your browser. You turn it on in each browser on each device, and Proton’s help center says it may not work in private browsing.

Moving over is built in. The first screen of my free Proton inbox offered to bring mail in from Google, Yahoo, or Outlook. Proton’s pricing page lists this Easy Switch tool on every plan.

Proton’s help center says Easy Switch can also connect your Gmail address, so you can keep sending from it inside Proton. A large Gmail archive won’t fit in 1 GB, so check your Google storage use before you import. The setup steps are in how to use Proton Mail.

Law and government requests

Proton AG is in Geneva, and its privacy policy says it’s governed by Swiss law. It says it discloses data only on a binding request from the competent Swiss authorities. Its transparency report lists 9,301 legal orders for Proton Mail in 2025, of which it contested 988 and complied with 8,313.

Proton says it can’t decrypt stored emails. Account data is another matter. In 2021 it logged a French activist’s IP address under a Swiss order, its own blog post says.

Google LLC is a U.S. company, and its privacy policy says it shares information to respond to legal process or an enforceable government request. Its Transparency Report data lists 119,082 requests for user data from U.S. authorities in 2025, not counting requests to preserve data.

For search warrants and subpoenas, the two biggest types, Google disclosed some data in 88% to 90% of cases. These figures cover all Google services, not only Gmail, so they don’t compare one to one with Proton’s. This is not legal advice.

Proton Mail vs Outlook and Tuta

Outlook. The picture is close to Gmail’s. Outlook.com sends mail over TLS when the other provider supports it.

On a personal account, the Encrypt button needs Microsoft 365 Personal at $99.99 a year or Family, as checked on 10/09/2026. A free Proton account can send a password-protected email to an Outlook address. Our guide to sending secure email in Outlook has both sides.

Tuta. Tuta, formerly Tutanota, is a German encrypted email service. Its encryption page says it encrypts subject lines, which Proton doesn’t.

Tuta has no IMAP, and on 10/09/2026 it showed us prices only in euros. It has no affiliate program, so there’s no Tuta review here. It’s ranked next to Proton in our best secure email providers list.

Who should pick Proton Mail

• You want a provider that says it can’t read your stored mail.
• You email other Proton users, or send the odd private message to a Gmail address with a password.
• You want an inbox without ads, and you can live with 1 GB free or pay $47.88 a year for 15 GB.

Who should pick Gmail

• You need lots of free space: 15 GB, shared with Drive and Photos.
• You read mail in Outlook, Apple Mail, or Thunderbird and don’t want to pay for that.
• You rely on fast search across years of mail and on Google’s other apps.

Verdict

On privacy and encryption, Proton Mail wins. It stores mail with zero-access encryption, encrypts mail between Proton users end to end, and sends password-protected mail to anyone for free. It also says it’s funded by subscribers, not ads.

Gmail wins on free storage, with 15 GB against Proton’s 1 GB, and on convenience, with free IMAP and search that needs no setup. Neither encrypts subject lines end to end, and both answer legal orders. If privacy is why you’re comparing, start with Proton’s free plan.
