# WhatsApp Blocks & Bans

> Reduce the risk of WhatsApp blocks and bans: watch spam-report rates, warm up numbers, collect opt-in, honor opt-out, and vary message patterns.

High-volume and/or non-consensual messaging can trigger WhatsApp's anti-spam mechanisms — rate limits, temporary blocks, and permanent bans. The practices below reduce operational risk.

## Critical metric: spam reports

Even a **small percentage of recipients marking your messages as spam — on the order of \~3%** — can lead to severe restrictions. Treat any increase in complaints or reports as an operational priority: pause campaigns, review targeting and consent, and reduce volume immediately.

## Warm up new numbers

* Use the number **organically** before automating — real two-way conversations first.
* Do not connect and automate immediately after the number is created/activated.
* Complete the profile (photo, name, description) before the first automated send.
* Ramp volume **gradually**: small batches first, scale only as engagement stays healthy.

## Opt-in and opt-out

* Only message contacts who gave **explicit, verifiable consent** (opt-in).
* Provide a clear opt-out (e.g. reply "STOP") and **honor it immediately**.
* Never buy contact lists or message people who have never interacted with your business.

## Risk factors

* Sending to many recipients who have never interacted with the number.
* Lack of explicit consent.
* Sensitive content and detectable repetitive patterns.
* Ramping volume during periods of higher moderation pressure.

## Defensive practices

* **Rotate and vary templates**: personalize beyond the basics and vary message structure so sends don't form a rigid, detectable pattern. For MARKETING template sends, the API's `marketingOptions.aiRewriteEnabled` flag can automatically vary the final text while preserving intent, and marketing sends receive an automatic randomized queue delay to space out pace.
* Validate gradually (small batches) before scaling up.
* Monitor delivery metrics and **reduce volume at the first sign of deterioration**.

<Warning>
  Platform users are responsible for consent/opt-in and compliance with applicable laws and WhatsApp's policies. Violations can result in your number being restricted or banned by Meta.
