Email on your own domain.
Free, and actually good

A proper address on a domain you own, starting at nothing. No ads, nobody reading your mail.

EVERY DAY

An inbox worth
opening.

Email on your own domain usually means putting up with something dull. Not here.

HOW IT READS

A list you recognise before you read it.

One row per conversation, and every sender keeps its colour. Newsletters and receipts sit in their own tab.

SENDING

Send as anyone on the domain

BLOCKING

Blocked means it never arrives.

The server files them into Junk as they land, so your phone never buzzes. Filed, not destroyed, so you can undo it.

PRICING

Priced by the mailbox,
not by the feature.

Reading, sending and blocking work the same whatever you pay. Three things move the bill.

See plans and pricing →
  • PEOPLE

    Free is one mailbox. Adding teammates, and the shared mailboxes they answer, is what a team plan buys.

  • ROOM

    Every plan keeps your mail. Paid keeps ten times as much of it, across more domains.

  • FLOW

    Included with every paid seat, not sold as a second subscription.

FAQ

Questions people ask

Yes, on every plan including the free one. You add the domain, we give you a record to publish, and once it verifies we handle the signing. Free covers one domain, Pro three, Team and Business ten.

Nothing about this
is hard to undo.

Your old mail imports whole, and any client can pull it back out.
