How to use unsubscribe tags correct
I recently got an increase in spam reports up to 0.22% .
I actually even got an email from a subscriber who wished to unsubscribe but reported that the unsubscribe link did not work.
As this could explain the increase in spam reports, I sent a test email to myself but the unsubscribe link worked just fine ...
Do you have an idea what could cause this increase in spam reports? Could it be that the link only works for certain email providers?
By the way, I am not sending more emails than usualy.
Thanks in advance for your help.
