Hmm no subscribers found to send to

I have 9 active subscriber lists, each less than 400 so I can send 1 an hour. Problem: this week no campaigns were sent as the prgram couldn’t find any subscribers.
“hmm, no subscribers found to send to”


Many have received as many as 100 emails from me over time. I processed each one making sure the time was correct.

I looked at each list and all subscribers are listed with a green thumbs up. The program cannot export or send to any of them…
Help!

@AmyM What error do you see when trying to export the subscriber lists? Are you sure the correct lists were selected? Are you using the segmentation plugin to filter recipients? Are you resending a campaign that has already been sent to the subscribers (this won’t work as phpList will only allow a campaign to be sent to the same subscriber once)?
