WhatsApp broadcasts without getting blocked

Why numbers get restricted

WhatsApp protects its users from spam. Every time someone blocks you, reports you or ignores your messages, it counts against your number. If negative signals pile up, Meta lowers your quality rating, pauses the templates involved, and can restrict how many people you may message—or, for repeated abuse, disable the number.

Get real opt-in

• Collect opt-in where customers already interact with you: checkout, account sign-up, in-store QR codes, a website chat button.
• Say what you’ll send (“order updates and occasional offers on WhatsApp”) and record when and where consent was given.
• Honour opt-outs instantly. Engage marks a contact as opted out when they reply STOP and never sends them marketing templates again.
• Never upload bought or scraped lists.

Send fewer, better messages

• Segment. Send the offer to customers who bought in that category, not to everyone.
• Personalise. Use the customer’s name and something relevant—their last order, their city, their plan.
• Add value. A useful reminder beats a generic discount blast.
• Include a way out. A “Stop promotions” quick-reply button turns a potential block into a clean opt-out.
• Mind the time. Send during waking hours in the recipient’s time zone; Engage can hold messages to a send window.

Respect the per-user marketing limit

Meta caps how many marketing templates a person receives from all businesses over a period, and the cap adapts to how that person engages. When a delivery is held back, the send fails with error 131049 and you aren’t charged. Utility and authentication messages don’t count towards this limit, and Meta doesn’t apply it in some regions (such as the EU, UK, Japan and South Korea).

Practically: don’t retry 131049 failures immediately, avoid sending several promotions in quick succession, and keep transactional updates in the utility category.

Watch your quality rating

Your number’s rating is green (high), yellow (medium) or red (low). It affects whether your messaging limit can grow. Check it after each campaign; if it drops, pause marketing, review the templates with the most blocks, and resume with a smaller, more engaged audience.

A pre-launch checklist

1. Everyone in the audience opted in; opted-out contacts are excluded.
2. The template is approved in the right category and personalised.
3. There is a clear opt-out (button or “Reply STOP”).
4. The audience fits your daily messaging limit, or the campaign is throttled.
5. You checked the cost and excluded contacts in the campaign estimate.
6. You sent a test to yourself and checked links and media.
