It is recommended to wait 2-3 weeks after registering a number on WhatsApp before linking it to SegraSend or any automation tool. Warm up the number by exchanging messages on the WhatsApp app first.

Recommendations and tips for WhatsApp number warm-up:

1. Start Low & Increase Gradually: Begin with 5-10 messages a day to known contacts, then slowly ramp up to 50-100 messages over a week or two.
   

2. Engage with Known Contacts: Focus on messaging people who know you to reduce the chance of being flagged as spam.
   

3. Vary Message Content: Send a mix of texts, images, and voice messages for a natural communication flow.
   

4. Focus on Engagement: Aim for replies and interaction to build trust and demonstrate that your messages are welcome.
   

5. Introduce Business Messages Slowly: Avoid heavy promotional messaging early on—start with informational or helpful content.
   

6. Avoid Automation Initially: Stick to manual messaging for the first couple of weeks to establish trust before automating.
   

7. Follow Best Practices: Only message opted-in contacts, and avoid sending unsolicited or bulk messages.
   

8. Monitor Metrics: Watch for engagement levels and any signs of issues (e.g., blocked numbers or warnings).
   

9. Use SIM-based Numbers: They're more trusted than VoIP numbers.
   

10. Stay Consistent: Keep messaging regularly to maintain trust and avoid sudden usage spikes. These steps will help ensure your WhatsApp number warms up safely, minimizing the risk of bans or restrictions.
