Sending DM's to potential customers, tell me why this wont work.

Im considering hiring some VA's to reach out to potential customers and letting them know about a promotion we're having. These "potential customers" are interested in pages within my niche. I see some possible issues here but I am absolutely clueless what will actually happen. Here are some potential issues, fill me in on the reality of these if you dont mind.

-Facebook bots not allowing the messages to go through due to certain words
-links causing me to get flagged as spam (this is avoidable)
-volume of messages sent

My margins are quite high and I really dont need that many sales to cover the cost of the VA's.


Thanks guys!

I can't say exactly what will happen, but spamming private messages
in Facebook may put your account at risk. You won't know until you give it a shot though.

I heard FB spamming became really hard nowadays, I'm not sure if it is still possible. If you don't mind is it possible to know more or less your niche actually?
