Alternatives
Proton Mail alternatives
Proton Mail is a strong default: end-to-end and zero-access encryption on by default and built-in PGP. If you want to pay in a way Proton does not offer, use standard mail apps without Bridge, or avoid a username and password, here are the providers worth checking and what each trades away.
Last verified 14 November 2026
Why people look for a Proton Mail alternative
- You want standard IMAP and SMTP without Proton Mail Bridge, which Proton lists for paid plans.
- You want to pay with Monero directly. Proton's payment page lists Bitcoin, cards, PayPal, Apple Pay, Google Pay, cash and bank transfer, and we found no direct Monero option.
- You want a free plan with more than one address.
- You would rather sign in with an account number than manage a username and password.
What to check before you choose
- Whether mail is encrypted zero-access by default or only if you opt in.
- Which payment methods the plan you need accepts, and whether any require personal details.
- Whether IMAP and SMTP are included on the plan you would actually use.
- Whether you can sign up and recover access without a phone number or another email address.
- Where the servers are and who owns the company.
- Whether you can export all your mail if you leave.
A shortlist, with the trade-offs
Tuta
Best for: Default encryption of subject lines, calendar and contacts, open-source clients and servers in Germany at a low entry price.
Trade-off: No OpenPGP, no IMAP support found on its pages, and crypto only through gift cards from a reseller.
Mailfence
Best for: OpenPGP key management built into the webmail on every plan, a Belgian company and Tor access.
Trade-off: Sign-up needs an alternate email address, and mail apps over IMAP are only on paid plans from Entry.
mailbox.org
Best for: A paid German mailbox with PGP and S/MIME, IMAP, custom domains, disposable addresses and cash-by-post payment.
Trade-off: No permanent free plan, no crypto payment found, and the cheapest plan is annual only.
Posteo
Best for: A very inexpensive German mailbox with no personal details at sign-up, prepaid credit, cash payment by post and encrypted mail storage.
Trade-off: No free plan or trial, no custom domains, and no crypto payment found.
VaelMail
Best for: Signing up with no phone number or recovery email, keeping sites apart with receive-only aliases, paying in crypto with no card, and reaching your mail over Tor or without JavaScript.
Trade-off: A lost account number cannot be recovered. Free cannot send. The encrypted mailbox is optional and not zero-knowledge, and VaelMail is a small independent service without the apps, integrations or track record of the large providers.
Common questions
What is the best Proton Mail alternative?
It depends on what you are missing. Tuta encrypts more by default, Mailfence has OpenPGP built into the webmail, mailbox.org and Posteo are inexpensive German mailboxes with IMAP, and VaelMail needs no phone or email and takes crypto directly.
Does Proton Mail require a phone number?
Proton's own guide says it does not, though you may be asked to confirm you are human with a CAPTCHA or an email code.
Is there a Proton Mail alternative with IMAP on a free plan?
VaelMail Free includes IMAP access with app credentials. Check each provider's plan table, because IMAP is often reserved for paid plans.
