@MichaelVGG you should not have any issues with messages in the DMs - as far as I know you won’t get in trouble for talking to several people.
You do have to be careful if you’re sending public comments replies - this is where there are restrictions.
I don’t have the exact threshold, but for public comments replies, my rule is that if the page has a lot of engagement, we just leave it off and just DM when they reply.
Hope this helps!
So basically I can DM 150 people/hr?
And what if somebody follows my page? Is it the same instance when somebody comments on a post?
