Warm up a brand-new WhatsApp account for at least 15 days before its first campaign, and 30 days if you can. Start with about 5 to 10 two-way messages a day and add slowly, roughly 10 more a day each week. Very new SIMs and numbers with past bans need longer, up to 60 days.
The core protocol covers days 1 to 14 in three phases. The timeline cannot be meaningfully compressed, but the daily warm-up work can run on autopilot. Here's the day-by-day schedule, why each phase matters, and how a WhatsApp warmer like Wassuply runs warm-up while Health & Risk tells you when each number is ready. For the bigger picture, read the complete WhatsApp warmer guide.
It's tempting to ask: "Can I do 20 on day 1, 50 on day 2, 100 on day 3, 300 on day 4, and be warmed in 5 days?"
No. The warmup timeline is not about hitting volume milestones, it's about accumulating days of behavioral history. WhatsApp's systems need to see consistent, human-like behavior over a sustained period. Each day of warmup is one more day of data proving the account is not a bot that appeared yesterday and started spamming.
Think of it like a credit score: you can't build 2 years of credit history in 6 months by spending more. More spending on a short timeline doesn't create history, it just creates a spending spike. Similarly, higher message volume on a compressed timeline doesn't create behavioral history, it just creates a volume spike, which is exactly what triggers bans.
| Days | Daily Volume | Activity Type | Can Send Campaigns? |
|---|---|---|---|
| 1-3 | About 5-10 | Conversational only | No |
| 4-5 | About 10-15 | Conversational + light pairs | No |
| 6-7 | About 15-20 | Conversational + pairs | No |
| 8-10 | About 20 | Steady warm-up rhythm | No |
| 11-14 | About 20-30 | Pre-campaign conditioning | No |
| 15-29 | Under your Health & Risk limit | First small campaigns | Yes, start small |
| 30+ | Under your Health & Risk limit | Recommended campaign start | Yes |
These volumes are close to what Wassuply's Health & Risk suggests for a brand-new SIM: roughly 8 warm-up messages a day in week one, adding about 10 a day each week, capped at around 30 a day for numbers under six months old. Older numbers start higher. For what to do once a number is live, see a new WhatsApp number's first 30 days.
Not all messages are equal during warmup. The goal is to build a realistic behavioral profile, so the messages need to look real:
Manual warmup requires hours of daily messaging across multiple accounts for 15 to 30 days, typing varied messages, tracking daily volumes per account, escalating on schedule, and managing inter-account conversations. This is why most people skip warmup, and why they get banned.
Wassuply takes the daily work off your hands:
After warm-up, campaigns go out with random 30-90 second gaps, batches of 10 and 1-5 minute breaks. No tool can honestly promise you'll never be banned; the rest of the rulebook is on how to avoid a WhatsApp ban. Comparing tools? See the best WhatsApp warmer software in 2026.
Start warm-up once. Health & Risk tells you when each number is ready. $397 lifetime licence, unlimited numbers.
Yes, and you should. Wassuply warms all connected accounts in parallel, there's no reason to warm them sequentially. If you plan to use 20 accounts, connect all 20 on day 1 and enable warmup on all of them. At least 15 days later (30 is recommended), Health & Risk shows you which of the 20 are ready for campaign distribution.
If you have an existing aged WhatsApp account with chat history, it starts from a stronger position, and Health & Risk reads its age and history to set its own plan. But for brand-new accounts, there's no shortcut. 15 days is the minimum before the first campaign, and 30 is recommended. Rushing it invites the same ban the warm-up was meant to prevent.
No. There is no separate warm-up process for WhatsApp Business. Both account types follow the same protocol, and Wassuply warms both the same way. A Business profile does not exempt a new number from the same scrutiny when it starts messaging strangers.
