After a good first campaign, the temptation is obvious: if one broadcast brought orders, two a week should bring more. WappBlaster users who run bulk campaigns on the official WhatsApp Business Platform usually discover the limit the hard way, through a falling quality rating rather than falling sales. Frequency on WhatsApp is a per-person decision, not a calendar one, and getting it right protects the number you depend on for every other message.
Measure WhatsApp frequency per person, not per campaign
A jewellery showroom in Ahmedabad might run a bridal collection campaign, a gold rate alert, a festive offer and a store event invite in the same week. If all four go to the full list, every contact gets four messages. If the bridal campaign goes to contacts tagged "wedding enquiry", the gold rate to "rate alert subscribers", and the event invite only to Ahmedabad contacts, most people receive one. The business sends the same total volume but feels far less pushy to each recipient.
That is why segments based on tags, city, source and behaviour matter more to frequency than any schedule. Before every send, ask how many marketing messages this segment has already received in the last 30 days.
A starting campaign frequency for each audience
| Audience | Suggested marketing frequency | Notes |
|---|---|---|
| Recent buyers (last 60 days) | 2 to 4 a month | They know you; relevance still decides |
| Subscribers who asked for alerts (rates, new stock) | As agreed when they joined | Daily is acceptable only if they signed up for daily |
| Older contacts, no reply in 6 months | 1 a month or less | Highest block risk |
| Trade or B2B buyers | Weekly price or stock update | Treat it as a service, keep it short |
Utility messages such as order updates and appointment reminders do not count against this budget, because the customer expects them. They should never carry promotions, though, or they stop being utility.
Signals that your WhatsApp campaigns are too frequent
Reply rate is a misleading guide. A loyal core keeps replying even while quieter contacts start blocking. The numbers to watch after each campaign are opted-out counts and Meta's failure reasons in campaign analytics, plus the number's quality rating. WappBlaster monitors quality rating and alerts you when it changes, which is usually the earliest warning that a segment has had enough.
- Opt-outs climbing on two consecutive sends to the same segment.
- Quality rating dropping from high to medium.
- Read counts falling while delivered counts hold steady, which suggests people have muted the chat.
Recovering a WhatsApp campaign when blocks spike
If quality drops, stop marketing sends to the affected segment for two to three weeks and keep only utility traffic running. Review the last two campaigns: was the audience wider than usual, did the offer feel generic, did the send land late at night? When you resume, start with your most engaged segment and a message that gives something useful, such as a back-in-stock alert, rather than another discount. The guide on avoiding a WhatsApp Business number block covers the policy side in more depth.
Let recipients set their own WhatsApp frequency
A quick-reply button such as "Fewer messages" next to "Stop" gives contacts a middle option. Those who tap it can be tagged and moved into a monthly-only segment instead of being lost. Similarly, a welcome message can ask new subscribers what they want: "New arrivals", "Offers only" or "Festival sales only". Their choice becomes a tag, and your sends respect it.
When a fixed campaign frequency is the wrong idea
Avoid sending on a calendar just because "Tuesday is broadcast day" if there is nothing new to say. Avoid catch-up blasts after a quiet month; sending three campaigns in one week to make up for it lands worse than staying quiet. And do not raise frequency to fill a sales gap at month end. That is exactly when blocks rise and the quality rating takes the hit.
How campaign frequency shows up on the bill
The annual WappBlaster fee is fixed at ₹7999 ($200) for Indian businesses, so sending less never costs more in platform terms. Meta's marketing charge applies to each delivered message and is passed to you itemised and at cost, which means trimming wasted sends to disengaged contacts saves money directly.
