When trying to mass email my entire userbase, the "Message count between" seems to be preventing me from accessing our entire userbase. If i leave it with the -1 which is supposed to be unlimited maximum msg count, i only am able to access 149 members out of 15,000 or so. Yet if i increase this amount to "99999" i am able to access 11,000+ members.
There's no difference between the code here and searching for users. If you leave the default settings, can you search for users? This isn't something I can reproduce and I don't see why it would trigger unless there is an add-on or some other input manipulation happening.
Also confirm the option regarding only contacting users opting to receive emails.
its not doing it anymore after i got it to finally send the mass email, go figure, i spent 20 minutes manipulating settings trying to get the entire list to come up and it wouldnt do it until i finally changed that one option lol
