Aster Mail vs Riseup Email

Aster Mail is an open-source email service with a free plan and paid tiers. It supports web, desktop, and Android, with an iOS beta on TestFlight; native desktop apps are available for Windows, Mac, and Linux. Aster Bridge lets desktop mail apps connect over IMAP and SMTP. Mail between Aster accounts is automatically end-to-end encrypted and uses hybrid post-quantum encryption. The free plan costs nothing and includes 10 GB of encrypted storage, five aliases, one custom domain, two mail rules, attachments up to 25 MB per message, and Bridge access; no trial or credit card is required. Aster says its email is hosted in Germany under EU privacy law and that it does not use ads, inbox scanning, or AI on the inbox. QuickSwitch imports mail from Gmail, Outlook, Yahoo, Proton, and other IMAP providers. MBOX mailbox export is free on every plan. Paid plans start at $2.42 a month, billed annually, with the final amount determined at checkout. Aster Mail was founded in 2026 and is headquartered in Orlando, Florida, United States.

Riseup Email is a free email account available through webmail or a mail client. Riseup describes the service as part of movement-run communications infrastructure for activists and allies. New accounts require an invite code from someone who trusts the applicant, and each account has 1 GB of storage. Riseup recommends Thunderbird and lists mail-client options for Linux, Mac, Windows, Android, and iOS. Clients connect using IMAP or POP, with SMTP for outgoing mail. Riseup says messages are individually encrypted on its servers and can be unlocked with the account password, but the service is not end-to-end or client encrypted unless users add Mailvelope or another OpenPGP solution. It says it does not log users’ internet addresses or include the sender’s IP address in outgoing email. Riseup services have Tor onion services, and email to certain activist providers is delivered over them. Trash messages are deleted after 21 days and Spam after 7 days. Riseup does not back up all old messages, so users are responsible for keeping their own copies. The service is funded entirely by small user donations.
