Messaging People Who Have Not Saved You

The silent failure of broadcast lists

A broadcast list looks like it worked. It reports as sent, and nothing tells you that a large share of recipients never received anything because they had not saved your number.

That is the trap. People test a broadcast on colleagues who obviously have them saved, conclude it works, and then use it for an audience where most have not. The API removes the condition entirely.

Consent is the real constraint

Because reach is no longer limited by whether someone saved you, consent becomes the thing that keeps you legitimate. Meta requires opt-in before you message, and quality is scored on how people react.

Honour opt-outs immediately and permanently. Complaints and blocks drive your quality rating down, and a number that falls far enough has its sending limits cut regardless of how good the content was.
