I have a problem with the ENL newsletter plugin.
When I run a campaign (i did it twice so far, on a weakly basis)the same email arrives multiple times to each subscriber. Up to 24 - 50 mails with the very same content, at different hours of the same day.
I've already had to unsubscribe four people because of that.
It's driving me crazy because cannot figure out what controls this thing and how to stop it. Tonight I even deleted all campaigns from the Newsletter menu because the campaign that ran yesterday (26/09) and that was supposed to run in a week, sent out emails tonight as well at midnight and a couple more at 1 am. I even think that a couple of emails (with the same content) were sent out after I deleted the campaign, but I really hope I'm wrong.
Any suggestions? How does one deal with it?
