Just to provide more information, assuming you are referring to the email address k******er@yahoo.com:
On Saturday, January 13, 2024 1:08:27 PM Yahoo sent us a spam complaint for an email sent to that address. Unfortunately they don't really tell us why/how/who put in the spam complaint.
When we receive a spam complaint, the email is automatically added to our suppression list and we never email that address again.
I went ahead and manually removed your email from our suppression list so it should email again.
Since January, we are now on a new email provider. If we get a spam complaint again, it will tell us a tiny but more information about the complaint but only a bit more. If it does spam complaint again, I can at least share that data with you and you could contact Yahoo.
If you want to go in your AdminCP, email settings, and then do a test email to that address I can check the logs and see what happens.
