Bulk WhatsApp, done compliantly

WhatsApp broadcast software that doesn't get you banned

Send approved template messages to thousands of opted-in contacts through the official Meta Cloud API — with segmentation, scheduling, and per-message delivery reporting. You pay Meta's conversation rate directly, with no markup from us.

Most bulk WhatsApp tools are a ban waiting to happen

The market is full of tools that automate the consumer WhatsApp app or route through unofficial gateways. They are cheap, they work for a while, and then the number that your entire customer base knows gets blocked — permanently, with no appeal that goes anywhere.

  • Unofficial senders violate WhatsApp's terms outright, so a ban is a matter of when rather than if.
  • Blasting a non-opted-in list drives 'block' and 'report' taps, which pushes your quality rating down and shrinks your daily send limit.
  • Without template management you discover a rejection at send time, in front of a campaign deadline.
  • No per-recipient delivery data means you cannot tell a bad list from a bad message.
  • Providers that mark up Meta's per-message rate make high-volume campaigns quietly expensive.

What you get

Segmented campaigns

Build an audience from tags, custom fields, pipeline stage or past engagement, then send to exactly that group. Because tags accumulate from ordinary inbox work, useful segments already exist by the time you want to broadcast.

Template management with approval status

Create, submit and track Meta message templates from inside ChatSathi, with live approval status and rejection reasons surfaced before you build a campaign on top of one. Variables are validated so a send never fails on a malformed placeholder.

Opt-out handling built in

Contacts who opt out are excluded from every future broadcast automatically. Respecting that is both a Meta policy requirement and the single biggest lever on your quality rating.

Scheduling

Queue a campaign for a future date and time rather than sending at midnight because that is when you finished building it. Scheduled broadcasts run server-side, so nothing depends on your browser staying open.

Per-recipient delivery reporting

See sent, delivered, read and failed counts for every campaign, with failure reasons per recipient. That is what separates 'the message was wrong' from 'those numbers were never valid'.

Official Cloud API, 0% markup

Every message goes through Meta's own infrastructure on your own WhatsApp Business Account. Meta bills you directly at their published conversation rate — we never add a per-message commission.

How it works

  1. 1

    Get a template approved

    Marketing messages on WhatsApp must use a template Meta has approved in advance. Compose it in ChatSathi, submit it, and track approval status without leaving the app. We flag the common rejection causes before you submit.

  2. 2

    Build your audience

    Filter contacts by tag, custom field, pipeline stage, or engagement history. The recipient count updates as you refine the filter, and opted-out contacts are removed from the total automatically.

  3. 3

    Send now or schedule

    Fill in template variables from contact fields so each recipient gets a personalised message, preview the result, then send immediately or schedule it. Execution runs server-side with rate limiting that respects your messaging tier.

  4. 4

    Read the results and follow up

    Track delivery, read and failure rates per campaign. Replies land in your shared inbox as normal conversations, so the team can work them without switching tools.

Frequently asked questions

Is bulk messaging on WhatsApp allowed?

Yes, when it is done through the official WhatsApp Business Platform to contacts who have opted in, using message templates Meta has approved. What is not allowed is automating the consumer or Business app to blast contacts, or messaging people who never consented. ChatSathi only sends through the official Meta Cloud API, which is what keeps your number safe.

Why do I need an approved template to send a broadcast?

Outside a 24-hour customer service window, WhatsApp only permits business-initiated messages that use a pre-approved template. This is Meta's mechanism for controlling spam. Templates are usually reviewed within minutes to a few hours, and ChatSathi shows you the status and any rejection reason directly.

What does a WhatsApp broadcast actually cost?

Two components. Your ChatSathi platform fee, which is flat and listed on the pricing page, and Meta's per-conversation charge, which depends on the conversation category and country. Marketing conversations cost more than utility or authentication ones. Meta bills you directly for those at their published rate — ChatSathi adds no markup, so your message cost is exactly Meta's cost.

How many messages can I send per day?

Meta assigns your number a messaging tier that caps how many unique customers you can initiate conversations with in 24 hours. New numbers start low and the tier increases automatically as you send consistently while keeping a good quality rating. ChatSathi respects your current tier when executing a broadcast rather than firing everything at once and burning through it.

What happens if my quality rating drops?

Meta lowers your messaging limits and, if the rating stays low, can restrict the number. The causes are almost always the same: messaging people who did not opt in, sending too frequently, or sending content recipients did not expect. Honouring opt-outs, segmenting properly, and not over-messaging are the fixes — all of which ChatSathi is built to support.

Can I personalise each message in a broadcast?

Yes. Template variables are mapped to contact fields — name, city, order reference, or any custom field you define — so every recipient receives a message filled in with their own data. You can preview the rendered result for a sample contact before sending.

Do replies to a broadcast come back to me?

Yes, and this is where broadcasts stop being a one-way blast. Every reply arrives in your shared inbox as a normal conversation with the full contact record attached, so your team can pick up the thread and, if it is a real lead, push it into the sales pipeline.
