Why people switch to Curo
- Fastmail's rules are precise but static; Curo's triage adjusts as your priorities actually change.
- Your Fastmail account joins every other mailbox you use in one triaged, unified inbox.
- Replies are drafted in your voice instead of left for you to type from scratch.
- You keep Fastmail's privacy-respecting hosting; Curo adds the AI layer on top via standard IMAP.
Fastmail is one of the best pure IMAP hosts available if you want speed, privacy, and full control over rules. Curo is the better fit once you want that mail actually prioritized for you, and unified with every other account you run.
Questions
Can Curo connect to a Fastmail account?
Yes. Fastmail supports standard IMAP with an app password, and Curo connects the same way it would any IMAP mailbox.
Will using Curo change how Fastmail's rules and search work?
No. Fastmail's own rules, search, and masked addresses keep working exactly as before. Curo reads your Fastmail inbox and adds AI triage and drafting on top, it doesn't modify Fastmail's settings.
Is Curo as privacy-focused as Fastmail?
Curo is end-to-end encrypted and private by design. Connecting Fastmail to Curo doesn't require giving up the privacy commitment either service makes.
Can Curo unify Fastmail with my other email accounts?
Yes. Curo connects Fastmail alongside Gmail, Outlook, or any other provider into a single triaged inbox.
