Hey!
Thank you for your advice!
However, I receive some messages telling that my newsletter was not read, and litterally telling PHISHING being the reason why it was not read and deleted.
Hey!
I send out a newsletter almost every third week concerning the activities of our club.
Some of my adressees' mail system reply me that my newsletter was not read/was deleted because of phishing.
How can I avoid that?
