Keeping your number safe
How WhatsApp bans numbers, what Tenashi does about it, and the habits that keep yours working.
This is the most important page here. A banned WhatsApp number is generally not recoverable. You lose the number, its conversations on the customer's side, and the trust attached to it. No tool can undo that — so the whole approach is prevention.
What actually gets numbers banned
Not volume by itself. What WhatsApp reacts to is the pattern:
- messaging people who never messaged you
- sending the same text to many people in a short window
- a new number behaving like an established one
- and above all, people blocking or reporting you
That last one carries the most weight. WhatsApp's strongest signal is recipients telling it you're unwanted.
What Tenashi does
Pre-send checks. Risky sends are assessed before they go. A clearly risky one is blocked with the reason, and you can override if you're sure. A borderline one is allowed with a warning and logged.
Pacing. Sends are queued and throttled per number rather than fired at once. Broadcasts go out gradually. This is why a large broadcast takes time — that's the protection working.
Daily limits that scale with age. A number linked yesterday can send less than one that's been active for months, because a new number sending heavily is the clearest possible ban signal.
Backing off when WhatsApp pushes back. If WhatsApp signals that you're reaching out too fast, the number is parked and messages are held rather than hammered through.
What you need to do
Message people who messaged you. This single habit avoids most risk.
Don't buy lists. Ever. Cold contacts block, blocking gets you banned, and it will happen faster than the campaign pays for itself.
Vary your messages. Identical text to hundreds of people is the pattern being looked for.
Warm up a new number. Normal conversations for a few weeks before any bulk sending.
Make it easy to opt out and honour it immediately. Someone who can leave politely doesn't press Block.
Watch your replies. Broadcasts that get answers are healthy. Broadcasts that get silence and blocks are a warning — stop and change the approach.
If your number is restricted
Act on it from the phone: WhatsApp's in-app appeal is the only route, and Tenashi cannot influence the outcome. Meanwhile, connect a different number so your team can keep working — your conversations and records stay where they are.
The realistic advice is that appeals often fail. Prevention is the whole game.
