Overview
What Posteo is#
A paid German email provider supporting cash-by-mail payment.
Threat-model fit#
For users who can accept German jurisdiction and want a payment channel that doesn’t bind their account to a card.
Strengths
- Cash-by-mail payment supported and well-documented — the operator explicitly does not bind payment to the account.
- Mailbox encryption-at-rest is available.
- Cooperative legal structure with a public transparency posture.
Caveats
- German jurisdiction.
- End-to-end encryption is PGP-only; not in-protocol like Tuta.
- Facts need re-verification by operator (last seeded 2026-01).
Verdict
Posteo is the gold standard for cash-by-mail email signup. The operator's policy explicitly de-links payment from account, and the price is low enough that anonymized cash is practical. German jurisdiction is the operator-side caveat.
