Stephanie, so sorry for the late reply. I have to look into why I’m not getting notified when people post on the forum.
I would use steph@stehb-editing.com
Many people do this, as it is common for editors to use their name in their domain since their name is their business name. It’s completely fine to have your name@domain that also has your domain.
But you can just do Steph instead of Stephb if you wanted to mix it up a little.
