Email for every address on your domain
Preinbox hosts mailboxes with catch-all delivery, IMAP and SMTP over TLS, and a web inbox that reads all of them in one list.
Accounts are set up by invitation.
Mailboxes without per-address setup
Any address on the domain receives mail as soon as it is used. Read it in the browser or in any mail client.
Catch-all delivery
Mail to any address on the domain lands in the catch-all mailbox. No address has to be created first.
One combined inbox
The web inbox reads the catch-all and every personal mailbox and sorts them into a single list, newest first.
Confirmation links
Each message shows its confirm or verify link at the top, with every other link listed below it.
IMAP and SMTP
Standard protocols, so Apple Mail, Outlook, Thunderbird and scripts connect with the usual settings.
TLS everywhere
Connections to the mail servers and the web inbox are encrypted. Plain-text ports are not offered.
Personal mailboxes
Named addresses get their own mailbox and password, and still show up in the combined inbox.
Connect any mail client
Use the full email address as the username and the mailbox password you were given. The server names come with your account.

Common questions
How do I get an account?
Accounts are set up by invitation. Write to hello@preinbox.com with the domain you want to use.
Do I need to create each address before it receives mail?
No. With catch-all delivery, mail to any address on the domain arrives in the catch-all mailbox. You can add a personal mailbox for an address when it needs its own password.
Can I use my own mail app?
Yes. Every mailbox supports IMAP for reading and SMTP for sending, over SSL/TLS on ports 993 and 465.
Where do I sign in to the web inbox?
At preinbox.com/login. After signing in you see every mailbox on the account in one list.
