So, i sent my first newsletter, and it seemed to parse thru all my members, so it wouldn't time out - and it sent! I don't recall setting up a list. At the time there were 173 members.
Now there are 212+ members. (They are rejoining from a transition away from phpbb)
This morning I tried to send my second newsletter. I hit 'send' - and it returned me to the admin control panel start. I tried to send it out again, then checked the report and saw that 0 had sent.
Then the third time i tried to use my same letter, from the dropdown, and the previous 'list'....... only 93 went out.
How did it go so smoothly the first time? I seem to be missing something.
