Complete Email Features

Everything you need for secure, private communication — and so much more.

Email Features

  • Masked Aliases: Create normal-looking custom email addresses, each with their own subdomain catch-all address, at will with a choice of 30+ domains.
  • Auto-expiring Aliases: Create date-based aliases (YYYYMMDD@alias.domain.com) that automatically stop accepting mail after the specified date.
  • Account Aliases: Use your account name across all available domains (turn on or off domains and catch-alls at will).
  • Unlimited Hosted Domains: Host your own domains with full feature integration easily from within our webmail.
  • Catch-all Addressing: Receive mail to any address at your domains.
  • Full Catch-All Control: Block/Allow aliases and addresses. Easily manage catch-alls as blocklist or whitelist.
  • SMTP-level Mail Control: Block addresses, domains, or TLDs (including countries) with User Unknown rejection at the connection. Blocked senders receive a “user does not exist” error and are removed from mailing lists automatically.
  • Wildcard Pattern Blocking: Block senders or servers using wildcard patterns (* and ?) for flexible, pattern-based filtering.
  • Server Hostname Blocking: Block mail by sending server hostname or domain, in addition to sender address blocking.
  • Block by Language: We also offer the ability to block by language or select only those languages you will accept. However, this has to be done after the connection and so can only be deleted or filtered, whereas all other blocking is at the SMTP transaction level.
  • Undo Send: Configurable 5-30 second delay with hover options to undo send or send immediately, preventing email mistakes.
  • Scheduled Send: Schedule anything that can be sent in a mail to be sent in the future; automatically detects custom SMTP servers.

  • Secure Link: Automatically password-encrypt attachments client-side with AES-256-GCM using WebCrypto API. We never see anything but the encrypted file, passwords are not stored by us, you receive download notifications, and files auto-delete after 24 hours.
  • Fetch Mail: Automatically retrieve email via POP or IMAP from other services with filtering options. Optionally encrypt retrieved mail automatically upon retrieval so it is protected at rest immediately.
  • Send via External Accounts: Send mail that appears to come from your other addresses, routed through the correct mail server for proper authentication. Replies land in the right inbox, not spam, and your IP address is never exposed.
  • Advanced Sieve Filters: Comprehensive mail filtering with custom rules, including auto-PGP encrypt actions.
  • Auto-forwarding: Forward all mail to existing accounts.
  • Out of Office: Easily create and schedule Out of Office replies.

  • Private WebDAV/CalDAV/CardDAV: Our own privacy-focused DAV server for syncing Calendars, Tasklists, and Addressbooks. Each shared device or person gets separate randomized credentials that reveal nothing about your account. Set per-person permissions, expiration dates, and revoke access instantly. Whitepaper here.
