I got this message from gmail smtp. It’s my first time dealing with this, does anyone have any guidance on how to start?

Hi @klarios0524 Thanks for posting! Gmail gives that response if your from domain name is not configured to designate May First as a legitimate sender. Fortunately, it’s fixable!

Specifically, you will want to add a “DKIM” and “SPF” domain name record to the DNS settings for the domain name in your from address. We have help files on each one here:

Feel free to follow up with any other questions.
