Send bulk WhatsApp to millions, across as many numbers as you need

One number has a messaging limit. A campaign does not have to. Spread a single send across many WhatsApp API numbers on the same account and clear lists that would otherwise take a week.

How do you send bulk WhatsApp from multiple numbers?

Meta caps each WhatsApp API number at a messaging limit (1,000, 10,000 or 100,000 unique customers per rolling 24 hours before unlimited tier). To reach millions inside a day you run one campaign across several registered numbers at once. WappBlaster distributes the audience across the numbers you connect, paces each against its own limit, and reports delivery for the whole campaign in one place.

Capabilities

What you get

Everything here is documented and shipping today, not on a roadmap.

Audience split across numbers

The recipient list is divided across every connected sending number, so total throughput is the sum of their limits rather than the ceiling of one.

Per-number pacing

Each number sends at its own tier. A new number on the 1,000 tier is not pushed past it just because an older number alongside it is unlimited.

One combined report

Delivered, read and failed roll up across every number in the campaign, and also break down per number so a struggling one is visible.

Quality rating protection

Opt-outs and blocks are applied account-wide, so a customer who opted out is not reached by a different number in the same campaign.

Rocket campaigns for the largest sends

A dedicated high-throughput campaign mode for the biggest lists, enabled per account.

Flat platform fee at any volume

Our annual fee does not move with volume. Only Meta’s own per-message charge scales, and it is passed through at cost.

Frequently asked questions

Straight answers about Send bulk WhatsApp from multiple numbers.

How many WhatsApp messages can I send in a day?

Per number, it is your Meta messaging limit: 1,000, 10,000 or 100,000 unique customers per rolling 24 hours, or unlimited at the top tier. Across ten unlimited-tier numbers there is no practical daily ceiling, which is how million-contact sends are done.

How do I increase my WhatsApp messaging limit?

Meta raises it automatically when you send consistent volume at a good quality rating. Send to opted-in people, keep templates relevant, and avoid the blocks and reports that drag the rating down. Business verification is required before you can move past the entry tier.

Link to this answer
Is sending from many numbers against WhatsApp policy?

No. Running multiple registered WhatsApp API numbers under one verified business is normal and supported by Meta. What is against policy is unofficial tooling that automates the consumer app, which is what gets numbers banned.

Does sending more cost more on your side?

No. The platform fee is flat and annual whatever the volume. Meta charges its own per-message rate, and we pass that through at cost with no markup.
