Give context to your contacts

A powerful address book that automatically surfaces recent conversations and upcoming meetings.

A full featured address book is a powerful thing. Of course you can add all the details you’d expect to a contact — emails, addresses, phone numbers and so on. But with Fastmail, your contacts also automatically surface recent conversations and upcoming meetings. You can compose a new message, or start a phone call, with just a tap.

On desktop, our smart sidebar will automatically bring up the relevant contact when you open a message, giving you the full context. Add a note to a contact so you never forget what you need to follow up with them, or how you met, or their kids’ names.

Family or business? You get a shared address book as well as a private personal one, so you can all stay up to date.
