How much does WhatsApp Business API cost in Mexico in 2026?

Three things change: marketing rises from USD 0.0305 to USD 0.0397, and from MXN 0.5614 to MXN 0.7298; utility templates inside the 24-hour window are charged; and service messages are charged above 1,000 per phone number per month. Utility and authentication keep their list amount.

The change starts on October 1, 2026 at 12am in your Meta Messaging account timezone, not at midnight in Mexico City. If your account sits in another timezone, that day begins a few hours earlier or later than you expect.

Meta charges per delivered message: each billable message counts on its own, and messages your customer sends you are free. Templates have been charged this way since July 1, 2025, by category and by the country of the number receiving them, except as the table shows; from October 1, 2026 so are the service messages beyond the free allowance of 1,000 per phone number per month.

For most Mexican accounts the hit is not the marketing increase but the two deliveries that become billable: the utility template you send after the customer has written to you, and the service messages beyond the monthly allowance. If your operation is support rather than broadcast, that is where the new invoice comes from.

From October 1, 2026, every WhatsApp Business phone number has one shared allowance of 1,000 delivered service messages per month, with no rollover into the next month. Above that allowance, each service message delivered in Mexico costs USD 0.0085 (MXN 0.1565), with no volume discounts.

A service message is the free-form reply, with no template, that your team or your agent sends inside the 24-hour customer service window a customer opens by writing first. From October 1, 2026 those replies are charged as soon as the number passes its monthly allowance.

An example, using arithmetic on the official rate from October 1, 2026: a number that delivers 3,000 service messages in a month has 1,000 inside the allowance and 2,000 to pay for. The sum is 2,000 times MXN 0.1565, which is MXN 313.00, or 2,000 times USD 0.0085, which is USD 17.00.

If a customer writes from the WhatsApp app on Android or iPhone through a Meta ad that opens WhatsApp and you reply within 24 hours, a free entry point window may stay open for up to 7 days from your reply. Messages delivered while it stays open pay none of these charges. Arriving from Google or your site does not open that window. So where your customers come from changes what you pay Meta.

Each provider decides whether it passes Meta's fee through at cost, adds its own fee, or folds everything into a single per-message rate. What follows are the sentences each provider publishes about its own fees, read on September 17, 2026. They are evidence of what that provider charges, never of Meta's amounts.

Always ask two things in writing: whether Meta's fee reaches you at cost or with a margin, and what the provider charges on top per message or per conversation. Watch the unit: Meta charges per delivered message, while some providers, such as Zoko, charge per conversation, and that unit does not compare line by line with Meta's.

Wati, ManyChat, Leadsales and Infobip publish no verifiable markup or per-message fee, so this page does not say what they do with Meta's fee.

Meta charges per delivered message, not per conversation: the cost depends on how many billable messages you send in each one. From October 1, 2026, 100,000 marketing templates delivered in Mexico cost USD 3,970.00 (MXN 72,980.00) and 100,000 utility or authentication templates USD 850.00 (MXN 15,650.00). Your provider's fee comes on top.

Service messages, the free-form replies inside the 24-hour window, are counted per phone number: if one number delivers 100,000 in a month, the first 1,000 are free and the other 99,000 cost USD 841.50 (MXN 15,493.50), if none of them goes out inside the free window a Meta ad opens. Meta does not charge for the messages your customer sends you.

The provider's share comes from what each one publishes, read on September 17, 2026. Twilio charges USD 0.005 per message, inbound or outbound, so 100,000 messages add USD 500.00 of Twilio fees on top of Meta, and on Twilio the messages your customer sends you pay too: a ten-message conversation, five each way, is ten Twilio charges. Gupshup charges USD 0.001 per message, USD 100.00 per 100,000, plus the conditional surcharge it publishes on marketing.

respond.io and Kommo say they add no per-message fee: you pay Meta's rate and, separately, their plan. 360dialog says the same of the product where it publishes it, not of every contract. Whaticket says Meta sets and charges the rate directly. Sinch and Bird publish no per-message surcharge that would let you do the sum, so this page does not do it.

Eva, our artificial-intelligence agent for WhatsApp with a CRM included, costs from $191 USD per month on an annual plan or $229 USD month to month. Meta bills these messages directly to your WhatsApp Business account, with the payment method you add in Meta. Eva does not collect these charges, and they are not included in your Eva plan price.

If a customer writes from the WhatsApp app on Android or iPhone through a Meta ad that opens WhatsApp and you reply within 24 hours, a free entry point window may stay open for up to 7 days from your reply. Messages delivered while it stays open pay none of these charges. Arriving from Google or your site does not open that window. If most of your customers come from Meta ads, these charges can be very low.

What an agent does change is the mix. Eva documents that reopening a conversation outside the WhatsApp window requires an approved template, and Meta charges those deliveries. It also charges service replies after 1,000 free per phone number each month, even inside the 24-hour window.

Before any platform price, check two of your own numbers: how many utility templates you send inside the 24-hour window, because from October 1, 2026 they are charged, and how many service messages each number delivers per month, because from that same date only the first 1,000 are free.
