Hello @JohnP7006 ,
Since test emails lack authentication, and appear as emails you're sending to yourself but are actually originating from another source, it can cause some email programs to be extra precautious. This is what's most likely occurring with your test emails to yourself.
If the test emails to other addresses are also going into junk, then this might indicate some degree of deliverability issues. Deliverability can have a lot of variables, from elements on our side, on your side, on the recipient's side, and in their email system company's side. It's also a generally good idea to set up additional authentication for your emails - whether that's through us if you have a free domain (e.g. Gmail, Yahoo, AOL, etc.) or via self-authentication if you have your own domain (such as through a business or other organization).
If you'd like to learn more about safelisting, and what it entails:
If you're wanting more in-depth, specialized insight on your current deliverability, it'd be worth speaking with one of our Deliverability agents.
