Paying Meta and WhatsApp Messaging Costs: Mumble’s Charges vs. Meta’s

Overview

When you use the WhatsApp Business API through Mumble, you pay two separate entities: Mumble for the service (the monthly subscription and overage costs), and Meta for the conversations with your customers (charged per conversation). This is the single most common cause of end-of-month surprises. In this article you’ll learn the distinction between the two charges, how Meta prices by conversation category, where to see the cost in every place, and how to forecast your monthly spend.

Two entities, two charges

Here’s the full picture:

Two charges, two payment methods, two separate invoices. Mumble does not bill you for what Meta charges, and vice versa.

Mumble’s charges

Mumble charges for using the platform: access to the chat, team management, advanced features (automations, Dolores AI, chatbot) and monthly quotas of message templates, API actions, chatbot actions, and AI credits. Billing runs automatically on the credit card connected to the account through Stripe.

Mumble’s subscription plans:

• Standard. Basic, suited to small businesses.
• Pro. Includes Dolores AI, advanced automations, smart campaigns, and Mumble Tracker.
• Scale. Larger quotas and dedicated onboarding.
• Enterprise. A custom contract, a dedicated account manager, and 24/7 support.

Overage beyond your quotas is purchased manually through "Upgrade operations" on the main page — there’s no automatic overage charge. For current prices and a full breakdown of the quotas in each plan, see the Mumble pricing page, as well as the Mumble billing portal and Upgrading or changing your plan.

Meta’s charges

Meta charges for every conversation you have with customers. A conversation is a 24-hour window that begins with the first message. Within the window you can send as many messages as you need — the charge is only for opening the conversation.

The billing categories

Meta prices by conversation type. Four categories:

Conversations a customer opens (Service Conversations) — for example a CTWA inquiry or a message the customer sends on their own — are free, provided you reply within 24 hours of the first message.

Conversations that start from a CTWA ad get an extended free window under Meta’s current policy. The exact details are updated by Meta from time to time, so for the policy in effect see CTWA, the complete guide.

Pricing by country

Meta charges a different price depending on the customer’s country. A conversation with a customer in the US costs more than one with a customer in India, for example. For businesses operating in Israel, the current rates (April 2026, stated in USD and before VAT) are:

For prices in other countries and Meta’s current rate policy, see Meta’s pricing documentation.

How to forecast your monthly spend

Forecasting your spend requires two separate calculations — one for Meta and one for Mumble.

Forecasting Meta spend

1. Estimate the number of conversations you open per month (campaigns, automations, business-initiated messages).
2. Estimate the mix between Marketing, Utility, and Authentication.
3. Estimate the mix across customer countries.
4. Calculate: multiply the number of conversations by the cost per category and country.

Example for an Israeli business sending 5,000 outbound conversations a month, 80% Marketing and 20% Utility, all to customers in Israel:

• 4,000 Marketing conversations × $0.0353 = $141.20
• 1,000 Utility conversations × $0.0053 = $5.30
• Total expected Meta charge: about $146.50 per month (before VAT)

Note: since Meta updates its pricing from time to time, check the current figure in Meta’s pricing documentation before a large campaign.

Forecasting Mumble spend

1. Choose a plan that fits your expected volume of message templates, API actions, automations, and AI.
2. Add overage costs if relevant (for example, exceeding your Dolores AI credits or your monthly message-template quota).
3. Add extra agents beyond those included in the plan, if needed.

Where to see the cost in every place

In Mumble

• Campaign report. For each individual campaign you see the total cost. See Reading campaign results.
• Billing portal. Historical Mumble charges and invoices.
• Main page. Subscription status, remaining quotas, and the option to purchase overage.

In Meta Business Manager

• Billing < Account spending. The total you’ve paid Meta.
• WhatsApp Manager < Insights. A breakdown of conversations by category.
• Billing < Payment activity. Historical billing transactions.

Practices for saving

• Choose the right category. A Utility message template costs significantly less than Marketing. You may not use Utility for marketing purposes, but if you have genuine order-confirmation messages, Utility is the right category. See Message templates, the complete guide.
• Make the most of the 24-hour window. Once a customer reaches out to you, the first 24 hours are free. Plan your communication within that window rather than opening a new conversation the next day.
• Use CTWA as an entry point. Conversations that start from a CTWA ad enjoy an extended free window under Meta’s policy — a good way to lower the cost of warm leads.
• Clean your lists before a campaign. Sending to inactive customers costs money with no result. Remove customers who haven’t replied in 6 months.
• Segment instead of sending to the whole list. A targeted campaign to a small audience usually performs better and also costs less than a blanket campaign to a large list.
• Monitor spend in real time. Don’t wait for the end of the month. Check Account spending in Meta twice a week.

Common issues

I got an unusually high charge from Meta this month

Go to Meta Business Manager < Billing < Account spending and select the specific month. Break the cost down by category: if most of the charge is Marketing, you probably sent larger campaigns than usual. If most of it is Utility or Authentication, an automation may be generating more conversations than you estimated.

How do I know which category a message template will count as?

The category is set when you create the message template, and it has to match the content. A marketing message template classified as Utility will be quickly spotted by Meta and suspended. See Message templates, the complete guide.

I sent a message to a customer who replied a few hours earlier — does that cost money?

It depends when you replied. If the customer messaged at 10:00 and you reply at 15:00 the same day, you’re inside the 24-hour window = a Service conversation = free. If you reply the next morning at 09:00 (less than 24 hours from the first message), still free. If you reply only two days later, the service window has closed and you’ve opened a new conversation charged by category.

I don’t see Meta’s charge. Where is it?

Meta sends invoices to the email set in Business Manager < Settings < Business Info. Make sure the email is correct. You can also see everything directly in Business Manager < Billing.

I was charged for conversations I don’t remember sending

Check whether you have active automations. An automation that sends a message template every time a conversation changes status can generate a lot of conversations you’re not aware of. See Automations in Mumble.

Why does my Mumble campaign show a cost — and which charge does it refer to?

The cost in the Mumble campaign report is an estimate of Meta’s charge for the conversations the campaign created. It is not an additional charge from Mumble. That charge will appear on Meta’s invoice at the end of the month.

The bottom line

Two separate charges: Mumble for platform usage, Meta for conversations. Forecast them separately and add them up, use the right category, and make the most of the 24-hour window — and monitoring twice a week will prevent end-of-month surprises.
