Hello @Drlinda112 ,
It looks like your test emails are sending. If you're not receiving a test when you send it to the same address you're sending from through us, then it's possible your email program is spam filtering it or outright blocking since it's not actually originating from you.
It's generally a 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:
Safelisting domains in a security system
Safelisting email addresses in an email client or security system
If you're wanting more in-depth, specialized insight on your current deliverability, it'd be worth speaking with one of our Deliverability agents.
