Your problem
My problem is:
Hello, the following is happening to me:

I have a campaign set up to send about 7 emails. The campaign trigger is a segment in which there are around 839 contacts, but when the corresponding email is sent, it tells me that it has only been sent to 649 contacts. What could be going on?

Thank you
