Yes, you can! Swapping out emails is very easy!

You first have to unlink your email from your account and then link your new one.

To unlink an email head over to the email providers menu and find the row with the email you would like to unlink and click the unlink button.

You might first have to disable warm-up before unlinking so be sure to do that if you had email warm-up enabled previously

Now you can add another email by clicking the sign-in with Google button.
