Same problem here .. checked this article https://kb.mailwizz.com/articles/my-campaigns-dont-send-theyre-stuck-in-pending-sending-status/
everything set up right. Campaign at once set to 100
still not sending anything
what else could be the problem?
I may add that I scheduled 3 campaigns before that and they got sent alright
