Introduction to WhatsApp Number Warm-Up
Why Warm-Up Matters
WhatsApp has sophisticated algorithms to detect and ban numbers that exhibit suspicious or spam-like behavior. When you connect a new WhatsApp number to any automation platform, you need to establish a reputation with WhatsApp's systems before sending bulk messages.
What Happens Without Warm-Up
Without proper warm-up, your number can be:
- Temporarily banned (24-48 hours)
- Permanently banned
- Messages stuck in "pending" status
- Severely reduced delivery rates
- Marked as spam by recipients
Delay connecting new WhatsApp accounts with any integrations or WhatsApp web for the first 7-14 days. Every new WhatsApp number needs warm-up.
The Warm-Up Process
The warm-up process involves gradually increasing your sending volume over 7-14 days while maintaining natural, engaging conversations. This helps WhatsApp's algorithms recognize your number as legitimate business communication rather than spam.
Getting replies during warm-up is one of the most important factor in building your number's reputation.
Who Needs to Warm Up?
You should warm up:
- ✅ Every new WhatsApp number - Every new WhatsApp signup needs warmup
- ✅ Business numbers - Even established business numbers connecting to automation
- ✅ Numbers that have been inactive - If a number hasn't been used in 30+ days
- ✅ After any ban - If your number was previously banned, warm it up again
