For a regular WhatsApp or WhatsApp Business app number there is no published number. What matters is the pattern: a brand-new number that sends 200 cold messages on day one will likely be banned, while an older, warmed number sending the same volume at a steady pace often is not. The official WhatsApp Business API is different: Meta publishes messaging limits for API numbers, starting at 250 unique users in a moving 24 hours and rising through 2,000, 10,000 and 100,000 to unlimited.
These are the caps Wassuply's Health & Risk uses for cold messages per number per day. Smart Send (when switched on) enforces them and slows or pauses a number when its risk score climbs.
| Number age | Safe cold messages per day |
|---|---|
| Under 3 months | 30 |
| 3 to 6 months | 50 |
| 6 to 12 months | 80 |
| 1 to 3 years | 150 |
| 3 years or more | 250 |
Caps are lower for numbers that were banned before (30 to 60 percent lower) and for numbers already in heavy daily use. A brand-new number should finish at least 15 days of warm-up before its first campaign.
Bans come less from a hard number and more from patterns: too much too soon, identical text to many people, machine-like timing, and people who never asked to hear from you reporting you. Warm-up, spintax, random gaps (Wassuply uses 30-90 seconds, batches of 10 and 1-5 minute breaks) and spreading volume across several numbers all lower the risk. The full playbook: how to avoid a WhatsApp ban.

It depends on the number's age and history. Wassuply caps cold messages at 30 a day for a number under 3 months old, rising to 250 for a number 3 years or older, and lower after past bans.
You can, especially if you send too much too soon, repeat identical text or message people who report you. Warming the number, using spintax and adding random gaps lower the risk.
In the app, Wassuply's Sending Calculator takes account age and list size and gives the safe daily limit and a realistic completion plan. Health & Risk shows the same limit for each number.
Yes. Meta publishes messaging limits for API numbers: new business portfolios start at 250 unique users in a moving 24 hours, then 2,000, 10,000, 100,000 and unlimited.
