Setup your Gmail Account
Start your new Gmail account at mail.google.com
Then follow the instructions from this helpful video. If you share your email address and initial password with me I can connect it to your website email address. This will allow your Gmail account to act as an alias to your website domain email address.
Create and Manage your Google Workspace Account
If you need a Google email for your domain then I highly recommend Google Workspace. Here I have several helpful videos from one of my favorite YouTube trainers, Stewart Gauld, to help you set up and manage your Google Workspace account.
