When you start a business, one of the first things you do is create an email. Then eventually you will get your business going and you’ll want a professional email with your domain at the end, whether to help MailChimp newsletters stay out of spam, or to show you are a legit business/blog. This tutorial will show you how to forward your old email to your new once the professional email is set up!
This is specifically for a Gmail account, which is what I highly recommend for your professional email via G Suite. It is fairly easy to set up but does include DNS setting changes so I am happy to help you set up your professional email if you need it!
