Hi Ben,
Hopefully, you can figure this one out.
I created a new list, and there are about 35 subscribers on it.
I created an autoresponder, and made one mail to go out 1 day after signup.
That one has sent ONE mail to ONE person. Nothing to the other 17 who signed up that day.
I created a second mail to go out 2 days after signup.
No mails has been sent here.
What did I miss?
