Send as any alias
Answer from the address they wrote to.

Pick which of your addresses each message goes out from. A reply opens on the one the mail arrived on, and you can still change it.

In short

What is an email alias?

An alias is another address that lands in the same mailbox, such as billing@ or support@. Sending as an alias means your answer leaves from that address too, so the reader sees the one they wrote to.

How it works

Pick the From on any message

The From row lists your addresses and greys out any that cannot send yet. Choose one, and your next new message opens on it too.

A default for new messages

General settings hold the address new messages open on. A reply's arrival address and your last pick both come before it.

The signature follows the address

Signature and open tracking come from whichever address is in the From row, so support@ can sign off differently from billing@.

Good practice

Getting the most out of it

  1. 01

    Reply, do not compose

    Answer inside the thread, so the reply keeps the address the mail arrived on.

  2. 02

    Default to your busiest

    Make your busiest address the default, since a new message opens on it until you pick another.

  3. 03

    Sign per address

    Give support@ and billing@ their own signatures, so the sign-off matches the From row.

Signature

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