mail.de

mail.de squeezes a full tier ladder into a small price range: a completely free, ad-free FreeMailZero account with 500MB, a free ad-supported FreeMail with 1GB, then four paid tiers from €0.99 to €6.49 a month that scale storage from 2.5GB up to an effectively unlimited 40GB-plus. That is a finer-grained ladder than most competitors here offer, letting a user pick almost exactly the storage and ad tolerance they want.

mail.de GmbH is registered in Nordhastedt, Germany, and states that every tier, including the free ones, supports PGP and S/MIME encryption rather than reserving it for paying customers, unusual generosity for a budget freemail provider. The higher paid tiers add a small environmental angle: mail.de says it plants one to three trees a year per subscription, depending on the plan.

Next to Posteo and Mailfence, mail.de is less well known internationally and publishes less detail about its data centres than Posteo's explicit green-energy claims. It does not offer zero-access encryption, so PGP here works the same way it does at Mailfence: opt-in protection for the messages you choose to encrypt, not a guarantee that mail.de itself cannot read the rest.

What mail.de does well

• PGP and S/MIME available even on free tiers
• Six tiers from free to effectively unlimited storage
• Paid tiers plant one to three trees a year
• German company and hosting
• Entry paid tier at just €0.99/month

Where mail.de falls short

• No zero-access encryption; PGP is opt-in only
• Less international recognition than Posteo or Mailfence
• Data centre details are less specific than Posteo's
• Free tiers are capped at 500MB–1GB

Standout feature. mail.de builds PGP and S/MIME into every tier, including the free ones, where most budget providers reserve encryption for paying customers.
