Warm-up and anti-ban limits
Nobody can promise zero blocks outside the official API. With the right brakes and careful use the risk drops a lot.
The number's brakes
Each number has five brakes that an admin switches on or off in Manage. They all start off: if you do not turn them on, messages go out right away and the risk is yours.
| Brake | What it does when on |
|---|---|
| Number warm-up | Limits messages in the first days, especially to new people. On day one the number can only reply to people who wrote to it. Messages per day start at about 15 and grow about 20% a day. If the number sits idle for more than 3 days, the ramp restarts from half. |
| Night pause for first messages | At night (7 pm to 9 am) first messages to people who have not written to you in the last 24 hours wait until 9 am. |
| Hourly and daily limit | At most 30 messages an hour and 200 a day. The rest wait for the next hour or day. |
| Human pacing between messages | A few seconds between messages, a longer break now and then, and "typing" before sending. |
| Wait between messages to the same person | A second message to the same person waits one minute after the first. |
Someone who wrote to you is never a new person: limits on first contacts do not apply to replies.
Always on
- One number, one IP: each number connects from its own fixed IP address in its country. If that connection is down, the number waits instead of going out another way.
- Drip queue: messages go out one at a time.
- WhatsApp restrictions: if WhatsApp restricts the number, you can only reply to people who already wrote to you. First messages are marked failed with that reason. The restriction usually lifts after a few hours.
Tips
- On a new number turn on warm-up and, at first, only write to people who know you.
- Go for replies: ask questions. Two-way conversations protect the number.
- Do not send the same text to many people at once: personalize with the name, spread sends over several days and numbers.
- Do not write to bought lists or to people who do not expect you.
- Send in business hours, or turn on the night pause.
- If WhatsApp restricts the number, stop: no messages to new people for a few days.
