I know I could have checked this earlier... but I didn't.
I need to send out a large campaign today, Advent Sunday, after having migrated a load of subscribers to Campaign Monitor. I created the campaign last night and submitted it for approval
Now I'm sitting tight, waiting ;-)
We have support staff working every day of the week, and we answer approvals within 12 hours even on the weekends. So you should never have to wait too long. If you have not seen a reply from us, check your junk folder just in case it has been caught up.
