Cheapest WhatsApp API providers compared (real pricing breakdown)
Sticker prices lie. We model platform fees + WhatsApp message costs at real volumes across five countries.
Quick verdict
At small-to-medium marketing volumes, $0/mo platform tools like Sendr dominate. At enterprise volumes, per-message negotiation matters more than subscriptions.
Every WhatsApp API provider page shows a monthly price — but that number excludes WhatsApp conversation charges, which Meta bills separately based on destination country and message category.
True cost = platform subscription + per-message platform markup (if any) + Meta WhatsApp conversation fees. This page models all three layers with worked examples.
We use Sendr's public calculator rates as illustrative Meta-cost estimates. Actual Meta pricing varies by BSP negotiation and changes periodically — treat numbers as directional, not contractual.
Methodology
For each provider we model: (1) published platform subscription (entry tier), (2) any additional per-message platform fee, (3) estimated Meta WhatsApp conversation charges using Sendr's calculator rates.
We compute total monthly cost at three volume tiers (500, 2,000, 5,000 messages) for five destination countries. Verify all provider pricing before purchasing.

Pricing examples
- A bakery in Mumbai sending 1,000 messages/month: Sendr ≈ $10 total (Meta costs) vs Wati ≈ $59 ($49 subscription + $10 Meta) vs AiSensy ≈ $49 ($39 subscription + $10 Meta).
- A tutor in Lagos sending 500 messages/month: Sendr ≈ $10 vs Gallabox ≈ $50 — subscription-based tools cost 5× more when volumes are small.
- A DTC brand in São Paulo sending 5,000 messages/month: Sendr ≈ $150 vs Interakt ≈ $199 — gap narrows at high volume because Meta costs dominate, but subscriptions still add up.
