This is one of the best newsletter plugins for wordpress that I have seen. One major drawback are the bounce mail delivery emails.
I have the bounce add-on and can see that from the 3000 subscribers, there are 120 failed emails.
But how can I bulk deactivate these emails?
Settings>mailpress>batches
there you can set the 'Max bounces per user'
After that number of bounces is reached it will automatically deactivate them.
I guess that does not seem to work.
I first tried 0. After 2 mailings none where deactivated, except the ones that unsubscripted.
So I set it to 1 and got the same results.
Does this work with you?
