What should I do to prevent WhatsApp from banning the number

In this document, we describe the rules that should be followed when connecting WhatsApp to a CRM system

The most correct answer is to use the official integration with WhatsApp

Recommendations for not falling into the ban

• Send messages to your warm base in small batches — around 15 contacts at a time, with pauses, and vary the time of day;

• Warm up the number before connecting it. A brand new number needs 10 days: leave it alone for the first 24 hours, receive only incoming messages on days 2-4, start replying to saved contacts from day 4, then grow the volume gradually. You can connect the number to the Service from day 5, but write to customers first only from day 11. An active number needs 2-3 days of live correspondence — and a number registered less than 24 hours ago must not be connected at all. Once warmed up, the number is ready for WhatsApp in your CRM;

• Take into account the user’s reaction to the message. Usually, it takes only 3 clicks on the “spam” button by the customer to block the number;

• The presence of links in messages increases the likelihood of a ban;

• WhatsApp does not publish exact limits, but the safe threshold for cold outreach is low — around 15-20 messages a day per number. If you need more, spread the load across several numbers;

• Use a device that has never had a banned WhatsApp account on it;

• Receiving incoming messages. The more incoming messages, the better — they build trust in the number faster than outgoing ones do;

• Don’t write the same messages. Use the masks that are in amoCRM and Birix24 to automatically replace the name or data of the fields.

Connecting a WhatsApp number to a CRM or a chatbot builder always carries a risk: the platform may treat it as a violation of the license agreement. Warming the number up and keeping the pace steady is what lowers that risk.

If You are Banned

Contact WhatsApp support and ask why the number was banned and whether the decision can be reviewed. Email no longer works: messages sent to the support address get an auto-reply saying it does not accept requests. Two channels are left — from the app (Settings → Help → Contact us), which is the main one because the request carries your account data, and the form at whatsapp.com/contact if the app will not open. Chances of getting the number back are high after a first ban.

Keep in mind that a ban resets the warm-up completely: even a three-year-old number looks brand new to the algorithm afterwards, and a second ban comes faster than the first.

Attention! Even if the number has been returned, do not put it back to work right away:

1. Contact our support first — we will clean up your integration. Without it the number may be blocked again;
2. Uninstall any third-party WhatsApp client you used and install the official app from Google Play or the App Store;
3. Wait 48 hours after the ban before logging in again. Turn the internet off for 10 minutes to get a new dynamic IP address;
4. Go through the full 10-day warm-up again, staying near the lower bound — 12-20 messages a day;
5. Turn off the “Check whether the client’s number is registered on WhatsApp” toggle in the integration settings;
6. Keep the first two weeks free of any bulk sending — only conversations with people who wrote to you first.

Do not register the number on a phone that already had a blocked WhatsApp account on it.

Conclusions

1. Do not send mailings from a number that you are afraid of losing — even a warmed-up number can be lost to a single bad campaign.
2. Do not use emulators or unofficial builds such as GBWhatsApp or WhatsApp Plus. That ban comes with no way back.
3. Sudden spikes are more dangerous than volume itself: a number that was silent yesterday and writes to dozens of strangers today is the first one flagged.
4. If you need regular bulk sending, move to WhatsApp Business API. A regular number is not built for that load, no matter how long you warm it up.
