Hello @DianneH9 ,
Your account's self-authentication is not active, based on what our admin system is showing. I checked in your account, and it's still pending so it won't be active until the changes made have been fully accepted between your host and us.
Additionally, if you're just sending these only to yourself, and they're test sends they're going to be more likely to show this anyway since test sends generally don't apply authentication - from us or your own self-auth setup.
Based on the banners showing, that would align with what I'm describing. For your actual send outs, you'll want to have your account actively set up for self-authentication.
