WhatsApp cost per conversation 2026: how the pricing works

Understanding the WhatsApp cost per conversation is the first question for anyone evaluating the official APIs for their business. Meta's pricing model has changed over time and it's easy to get confused between the old per-conversation rates and the more recent model based on the message and its category. In this guide we clarify how pricing works in 2026, with practical examples, and explain where Meta's cost ends and where SendApp's begins (or rather, where it isn't).

From conversation to message: what changed

Historically Meta charged per "conversation", meaning 24-hour windows within which you could exchange several messages at a single cost. Over time the model evolved toward a logic more tied to the individual template message and its category. The key concept to keep in mind today is that the cost depends mainly on two factors: the template category (marketing, utility, authentication) and the recipient's country. For the details and exact numbers, the official reference is always Meta's price list, which should be checked for your own area.

The factors that determine the price

• The template category: marketing typically costs more than utility.
• The recipient's country: rates vary by geographic area.
• The type of message: some service interactions may have different conditions.
• The overall volume, which over time can influence the conditions applied.

The official APIs: who bills what

Here lies the most important and most misunderstood point. When you use the official Meta APIs through SendApp, Cloud API messages are billed directly by Meta according to its rates. SendApp applies no markup on these messages: you pay Meta for the traffic and SendApp for the platform subscription. This transparency is useful because it lets you know exactly where every euro goes, with no hidden margins on the per-message cost.

WhatsApp Web via QR: zero per-message cost

The alternative to the official APIs is connecting WhatsApp via WhatsApp Web with a QR code. In this case there is no per-message cost: you don't go through Meta's price list, because you use your own WhatsApp as you would from your phone, automated by the platform. It is the cheapest solution on the individual message, suited to those who want to start without worrying about rates, keeping in mind though that you don't have the green tick, approved templates and the anti-ban channel of the official APIs, and that WhatsApp's usage rules apply.

An example of reasoning about spend

Imagine you need to send shipping notifications (utility) and occasionally a promotion (marketing). With the official APIs, the utility messages will weigh little on the budget and you can be generous, while marketing campaigns are best targeted at the right customers through tags to avoid multiplying costs. If instead your volumes are limited and you don't need the green tick and templates, WhatsApp Web via QR zeroes out the per-message cost and leaves you only the subscription. The choice depends on volumes, brand needs and price sensitivity.

Before estimating spend, separate utility messages (informational) from marketing ones (promotional). They are very different cost items and mixing them leads to wrong forecasts.

How to do it with SendApp

With SendApp Agent you choose the most suitable track: official Meta APIs with approved templates and green tick, or WhatsApp Web via QR code with no per-message cost. In both cases you manage broadcast campaigns with {name} variables, a CRM with tags to segment and send promotions only to those who count, and the AI agent that replies 24/7. Segmenting by tag is the main lever to keep marketing costs low when you use the official APIs.

How much it costs (SendApp)

The SendApp subscription starts at 19 euros per month and includes CRM, campaigns, AI agent and multichannel inbox. On top of that, only if you use the official APIs, comes the cost of messages billed directly by Meta according to its rates, with no SendApp markup. With WhatsApp Web via QR the per-message cost is zero and you only pay the subscription. For the exact Meta rate figures, always consult the official price list for your country.
