Hey everyone!

I’m running into a strange issue with my ManyChat broadcast, and I’m hoping someone here has seen this before.

Here’s what’s happening:

• I sent out a broadcast to 749 people.
• It’s been a while, and only 80 messages have been delivered. (But it says 730 are sent, and only 80 messsages delivered) Some even replied back to me, and are not in the “delivered” tap
• The rest seem stuck or delayed, and I don’t know why.
• This was a promotional message, but everyone on my list opted in to receive these.

I’ve checked a few things:
The broadcast is marked as "sent" in ManyChat.
My audience subscribed willingly and engaged with past messages.
I followed Meta’s rules—or at least I think I did!
 

 Is Meta throttling or delaying my messages?
Could some messages be blocked? How do I check?
Should I break this into smaller segments instead?
 Any settings I might have missed?
