Sending

One sign-off everywhere
however mail leaves

Set the sign-off once, and every address and every send path uses it.

Written once as markup. Every send path signs the same way.

How it works

Running in three steps.

  1. 01

    Write it as markup

    A live preview sits beside the box, showing what recipients get.

  2. 02

    Override an address

    Billing or support can carry its own instead of the shared one.

  3. 03

    Send from anywhere

    Composer, assistant, a rule and your code all sign the same way.

What it runs on

The parts doing the work.

Nothing here is a separate product. Each one is a piece of the mailbox you already have.

Signature

One sign-off for every address, and a different one for any address that needs it.

Workspace and address settings

Your account sets the defaults. A workspace can answer differently, and any address can have its own signature and tracking.

Workspace branding

Put your own mark and logo in the sidebar, in place of ours.
