Unlimited Aliases & Custom Domains
Fastmail lets you create unlimited email aliases under your domain or Fastmail domains. Masked Email generates disposable addresses for sign-ups, preventing spam and preserving your real address.
Ad-Free Email Interface
The web client is fully ad-free, with a clean, responsive design. Features include drag-and-drop folder management, conversation threading, and real-time notifications.
AI-Powered Search & Smart Folders
Leverage AI-driven search that finds text in messages, attachments, and contacts instantly. Smart folders automatically group messages by VIP status, unread, or custom criteria.
Scheduled Send & Undo Send
Compose an email and schedule it for later delivery. Undo Send holds outgoing messages for 15 seconds, allowing quick corrections of typos or recipients.
Snooze & Reminders
Snooze messages to reappear in your inbox at a chosen time. Set reminders on important emails to ensure follow-up.
Rules & Filters Automation
Create powerful server-side rules to tag, move, forward, or archive messages automatically based on sender, subject, or content.
Advanced Spam Protection
Fastmail’s proprietary spam filters, combined with open-source SpamAssassin, ensure unwanted mail lands in quarantine. Review and release or permanently delete at will.
CardDAV Contacts
Manage your address book with full CardDAV support. VIP contacts highlight messages and trigger custom notifications for priority senders.
CalDAV Calendars
Host multiple calendars via CalDAV with sharing permissions. Invite others, schedule events, and view combined calendars in month, week, and agenda views.
File Storage & WebDAV Access
Store files in Fastmail’s secure cloud and access via WebDAV. Attach large files without email size limits.
End-to-End Encryption (Optional)
Use S/MIME or PGP manually for secure messaging. Fastmail supports importing your encryption keys for encrypted email workflows.
