Why accounts get restricted

WhatsApp restricts accounts for behaviour that looks automated or unwelcome: sudden high-volume sending, messages to people who never opted in, identical text sent to hundreds of numbers, and links that get reported. For B2B outreach the platform is still one of the highest-response channels — the problem is usually the method, not the channel.

Six lines worth respecting

1. Warm up new numbers
Do not launch a campaign on a fresh number. Send normal one-to-one conversations for a week or two first, so the number has a human pattern.

2. Message people with a reason to be messaged
Collect numbers from business sources where a business contact is publicly published, and prefer decision-makers whose company is relevant to your product.

3. Vary content, never blast identical copy
Personalize the first line: company name, market, the product they actually handle. Identical bulk text is the fastest route to reports.

4. Control volume and pace
Send in batches with intervals and daily limits, not thousands at once. Slow sending with a high reply rate beats fast sending that gets blocked.

5. Give an easy exit
Make it simple to say "not interested" and honour it immediately. A clean opt-out protects the whole number.

6. Route interest to a place you own
When someone replies, move the conversation to a channel you control — a form on your own website, an email thread, a scheduled call. Do not leave the entire relationship inside one platform.

What good looks like

Collection, enrichment, scoring, outreach, follow-up. WhatsApp is the third step in that chain, not the first. Get the scored list right and the delivery problem mostly disappears.
