Sending WhatsApp campaigns to people who never agreed to hear from you is the fastest way to hurt your number's quality and get messages blocked. A healthy, opted-in list is the foundation of everything else.
Why opt-in matters
WhatsApp is built around consent. When people opt in and engage, your quality rating stays healthy and your messages get delivered. When they don't, you see blocks, low quality ratings and wasted spend.
Ways to collect opt-in
- Click-to-chat links on your site, ads and email signature.
- Website widgets that make the value of subscribing clear.
- Replies — when someone messages you first, that is a natural opt-in for that conversation.
- Forms with a clear, specific checkbox describing what you'll send.
Avoid buying lists or importing contacts who never agreed. It rarely ends well.
Make opting out easy
Always give a simple way to stop. A clear opt-out builds trust and protects your quality rating. Honour opt-outs promptly.
Keep it relevant
Segment your audience with tags and attributes so people get messages that matter to them. Relevance is the difference between a channel people read and one they mute.
A note on numbers
Specific quality thresholds, messaging limits and pricing are set by WhatsApp and can change. Check your current status in your account rather than relying on fixed figures.
