Hello @SusanW319 ,
As far as delivery, I'd advise setting your account for self-authentication, since you have your own domain. If you need further guidance on this, or need to address other delivery-related questions, I'd advise speaking with the Delivery team directly.
The "John Starks press release," shows "other device type" which means something other than a desktop device's browser / email program and mobile phone app / browser was used to view the email. This could be a smart watch, game console, or even a TV's internet or email app. If you're concerned about someone else checking out this email, you may want to check what devices are associated with the applicable Gmail account, and remove older ones you no longer use or have access to. Otherwise, I'd advise going through Google's support to identify where your email address would be getting accessed to cause this.
