# How to warm up WhatsApp account
Usually, during the first 7 days, WhatsApp will monitor the activities of each new number over a continuous 7-day period. It is recommended that you send test messages to different contacts and gradually increase the number of contacts each day. For example:
| Day 1 | Day 2 | Day 3 | Day 4 | Day 5 | Day 6 | Day 7 |
|---|
| 20 contacts | 35 contacts | 50 contacts | 65 contacts | 80 contacts | 95 contacts | 110 contacts |
**Tips:**

2. If you proactively send WhatsApp messages to them, it is very important that the first message prompts them to reply with something simple, like "YES." This way, WhatsApp is less likely to consider it as spam.
3. Then, divide your customers into small groups and gradually send messages to your contacts each day, slowly increasing the quantity. For example, send to 30 contacts on the first day, 60 on the second day, then 100, 200, 500, and so on, gradually increasing the numbers.
4. Maintain several WhatsApp numbers to use them alternately for blasting messages.
