In The E-Mail campaign area I want to send a Test E-Mail to my own adress

I did this several times and alway receive the conformation about success (RH flag)

But the test mail did never arrive in my Mail account.

For info:  Mail account works propper from other sender. Of Course.

At the last campaign, approx 2 month before it worked and I have had no problem ?

Who can help me ?

best regards

Siggi
