I am creating multiple campaigns (with the same HTML) through code - to send out to our list of subscribers. Would I then require an approval for each campaign?
Do let me know the process to be followed for this.
We just replied to you via support as well. You can see how the approval process works here. Once your first campaign has been approved you'll be able to send the rest of your campaigns going forward without delay. You would only need approval again if you're sending to a significantly larger list.
