Aster Mail vs Disroot 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.

Disroot Email provides free email accounts through webmail and desktop or mobile email clients. Its Roundcube webmail includes threaded messages, filters, folders, attachment previews, and MIME and HTML support. Mail clients can connect using IMAP over SSL, SMTP with STARTTLS, SMTPS with TLS, or POP over SSL; suggested options include Thunderbird, Evolution, KMail, ClawsMail, Mailpile, K-9 Mail, FairEmail, and iOS Mail. Connections to the mail server use SSL, while outgoing messages use TLS if the recipient’s server supports it. Messages remain unencrypted on Disroot’s servers unless users encrypt them themselves. Disroot says its data is stored on its own servers in a Netherlands data center. Email logs may include usernames, IP addresses, and sender and recipient addresses; they are retained for 48 hours and not backed up. The free email plan includes a 1 GB mailbox and 64 MB attachments. Plus addressing routes sub-addresses to the original mailbox. Users can link a custom domain for sending and receiving mail through a lifetime feature tied to a donation amount they choose. The service supports Android, iOS, Linux, macOS, web, Windows, and extensions.
