To set up a custom email domain...
- Select Settings from your Simplero Dashboard
- Select the Sender emails tab
- In the Email domain verification section, click the blue + Add email domain button
- Add the domain part of the email you want to send as (e.g. if you're sending as email@example.com, you would add the domain simplero.com)
The video below shows an example of how to set it up if your domain host is one.com, but it should work similarly with other hosts. Contact their support if you are in doubt as to how to add the TXT records.
