Bulk messaging
Sending messages simultaneously to many people, usually for campaigns.
Bulk messaging is sending the same message (or personalized variations) to many contacts at once. Done wrong, gets the number banned in hours. Done right, it's one of the highest-ROI strategies.
Three non-negotiable rules
- Consent — only blast to those who opted in. Bought lists = illegal spam.
- Warm-up — new numbers need 7-14 days of real use first.
- Pacing — random intervals (15-60s), small batches, daily caps.
Limits by number age
