Outbound Numbers Getting Flagged as Spam
I'm trying to figure out how and why my outbound numbers are getting flagged as spam. My research says as the volume of calls go up the chances of getting flagged rise, which makes sense. However, I have come to find out that its not as simple. I have two numbers with the same area codes who have very different contact volumes. One number launches roughly 600 calls per week and has 55 contacts whereas the other one launches more than 4000 calls per week and has 820 contacts this month so far. However the one with 55 contacts get flagged whereas the other one does not. Any ideas why this might be happening? What measures can I take to ensure my numbers do not get flagged as spam?
