Parameters influencing number blocking resistance:
Number age (number warm-up) #
The longer the number is registered with WhatsApp, the more resistant it is to blocking. If you have just registered a new number, then it is the most vulnerable, we recommend that you start warming up only the next day after creating a WhatsApp account. You need to be especially careful during the first 10 days of the number use. You should gradually “warm up” the number.
During the first 10 days of the number use:
- to link the account after 24 hours, details in the news
- do not send messages through the instance and do not create groups immediately after connecting, it is recommended to start sending messages the next day
- no more than 20 new recipients per day
Response ratio (incoming and outgoing messages ratio) #
The ideal case is when customers send messages to you first and add you to their contacts. However, in most cases, this scenario cannot be achieved. It is often required to start the dialogue first. If you send too many messages and do not receive a single reply in response, then you run the risk of getting banned. Aim for at least 30 responses from customers (30%) for every 100 messages sent. In this case, with 30% of replies, it can be assumed that the number is not at risk.
Address by name #
The first contact with the customer is very important. Try to address the customer by name. Thus you will increase the conversion of customer responses. Additionally, you make each message unique, which has a positive effect on the number blocking resistance.
Question in the first message #
In the very first message, explicitly request permission to send messages to the customer. It is important here to ensure that the customer enters into a dialogue with your number (bot) and at least replies something. This will help you achieve a good response ratio and drop out negatively minded customers.
Before sending a message, we recommend making a dialogue of the form:
Andrew, good afternoon! Do you want to check an electronic invoice from "My Company" enterprise?
Short messages #
Instead of one heavy message, send several small messages. This style is more like real communication than automated mailing.

(recommended) Minimal risk of blocking
- you send messages first, gradually boosting your customer base on the number
- at the first contact with a customer, you ask them for permission to communicate
- you address a customer by name, in a personalized way
- you receive at least 30 incoming messages from customers to 100 sent messages
- customers can always send a “stop” to unsubscribe
(not recommended) Maximum risk of blocking
- a number registered less than 10 days ago
- you send messages first
- same-type messages, no personalization
- a large number of recipients
- no replies from customers
