One of the most common questions we get from new users is: “Okay, but what does it actually cost?”
The ThinkMsg platform is free. But Meta charges per message when you use the Cloud API. Those charges are real, and you should understand exactly what you’re paying before you send your first campaign.
Here’s a transparent breakdown of a real sending scenario: 3,942 messages sent over the course of a month, across two message categories.
What We Sent
A church with roughly 1,600 registered members used ThinkMsg to send:
- Weekly Sunday announcement (Utility category): ~3 sends × ~1,000 contacts = ~3,000 messages
- Event invitation for a special programme (Marketing category): 1 send × ~942 contacts = 942 messages
Total: 3,942 messages
The Cost Table
| Message Type | Count | Rate per Message | Subtotal |
|---|---|---|---|
| Utility (announcements, reminders) | 3,000 | ₹0.13 | ₹390 |
| Marketing (event invitations, promotions) | 942 | ₹0.78 | ₹735 |
| Subtotal (ex-GST) | ₹1,125 | ||
| GST @ 18% | ₹202 | ||
| Total | ₹1,327 | ||
| ThinkMsg platform fee | ₹0 | ||
| Total cost | ₹1,327 |
Wait — that’s more than ₹500. That’s fair. The ₹500 headline applies to campaigns that are predominantly Utility category. If you’re sending mostly marketing messages, the cost is higher because Meta charges more for that category.
But let’s put ₹1,327 in context.
Is This Expensive?
For 3,942 WhatsApp messages with 95%+ open rates: no.
Compared to SMS: SMS costs roughly ₹0.10–0.15 per message in India — so 3,942 SMS messages would run ₹394–591. About half the price. But WhatsApp messages get read. SMS messages get ignored, or worse, reported as spam. The effective cost-per-read for WhatsApp is dramatically lower.
Compared to email: Email marketing tools charge ₹1,500–8,000/month for lists of this size — that’s just the platform fee, not per-message. And email open rates hover around 18%. You’d need to send to five times as many people to get the same number of actual reads.
Compared to boosted social posts: ₹1,327 won’t buy you meaningful reach on Instagram or Facebook in most Indian markets. You’ll spend more for less.
The Cheapest Way to Use WhatsApp
The biggest cost lever is message category. Utility messages (₹0.13) are 6× cheaper than Marketing messages (₹0.78). The category is set when you create a template and is approved by Meta.
Templates that qualify as Utility:
- Payment reminders
- Appointment confirmations
- Order status updates
- Event registration confirmations (after the user signed up)
- Weekly newsletters framed as service updates
Templates that are Marketing:
- Promotions and offers
- New product announcements
- Event invitations (unprompted)
- Re-engagement campaigns
If your content can legitimately be framed as a service update rather than a promotion, use the Utility category. The savings add up quickly at scale.
For a Typical Church or Small Business
A monthly communication programme — weekly announcements plus one event invitation — realistically costs:
- Utility-heavy (mostly announcements): ₹300–600 per month for 1,000 contacts
- Marketing-heavy (events, promotions): ₹700–1,200 per month for 1,000 contacts
That’s it. No hidden fees, no platform subscription, no per-seat charge. Just Meta’s metered billing, passed through at cost.
