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).
