Disroot

Disroot is the only nonprofit in this category: a project founded in Amsterdam in 2015 and run by volunteers, funded entirely by donations rather than subscriptions or advertising. The free account gives 1GB of mail with a 64MB attachment limit, and Disroot explicitly states it carries no ads, no tracking and no profiling — the same promise Posteo and Mailfence make, but here without any payment required at all.

The legal entity behind it, Stichting Disroot.org, is a registered Dutch foundation with a Dutch Chamber of Commerce number, and Disroot states that data is processed in a data centre in the Netherlands under the GDPR. IMAP, SMTP and POP all work over standard encrypted ports, so any mail client can connect, and extra mailbox storage is available in exchange for a further donation rather than a fixed subscription price.

The honest limitation is that Disroot is volunteer-run rather than a funded company, so support response times and uptime are not comparable to a paid provider like Posteo or Mailbox.org, and 1GB is tight next to GMX's or Migadu's free storage. For someone who wants a genuinely free, ethically run mailbox and does not need a service-level guarantee, it is the only option in this category built that way.

What Disroot does well

• Completely free, funded by donations, not advertising
• Registered Dutch foundation, Netherlands-only data processing
• No ads, no tracking, no profiling, by explicit policy
• Full IMAP, SMTP and POP support for any mail client
• Calendar and contacts included alongside the mailbox

Where Disroot falls short

• Volunteer-run, with no paid support tier or SLA
• 1GB free storage, tight next to GMX or Migadu
• No PGP or zero-access encryption
• No company behind it to hold accountable the way a subscription does

Standout feature. Disroot is the only mailbox in this directory that is entirely free and nonprofit, run by volunteers on donations rather than any subscription.
