WhatsApp automation: choose the right setup for the job
WhatsApp automation isn’t one tool. Choose it by the job: a welcome message, a buying question, a personalized follow-up or a booked call.

Chapter 01Decide
Which WhatsApp automation fits each job?
Pick the tool by the message you need to send, then check its cost and the 24-hour window.
Four jobs, the tool, the rule to check

Chapter 02Start
What should you automate first?
Start with one high-intent path: a prospect asks about your offer. More messages aren’t the goal; a better next step is.
- 01Inquiry“How much is it?”
- 02Useful answerOffer facts first
- 03One questionAsked for a reason
- 04Next stepPerson, resource or call
Prepare the offer facts, one clarifying question, an escalation rule and the condition for proposing a call. Save what the lead said, never a budget they didn’t share.
Chapter 03Setup
Set up WhatsApp automation in three steps
Welcome every new chat
Turn on the Business App’s greeting and away messages, or a Manychat Default Reply that asks one question. Menus and five messages to copy: WhatsApp auto reply.
Connect your number, build one path
In Manychat, connect an existing or new number on Pro or above; chat history doesn’t transfer (connection methods (opens in a new tab)). Then a welcome, one question and a human route: the WhatsApp chatbot guide.
Send the link, count the booking
Share your booking link when the lead fits or asks for a call. Count it only once the calendar confirms: WhatsApp appointment booking.
Chapter 04Rules
Respect WhatsApp’s message window
- 01They message youOpens 24 hours
- 02Reply freelyFlows and AI allowed
- 0324 hours passNo 7-day window
- 04Template onlyApproved, opted in
Unlike Messenger and Instagram, WhatsApp has no 7-day window: after 24 hours, only an approved template can reach the person, per Manychat’s messaging windows guide (opens in a new tab). On a Coexistence number, you can still write by hand from the Business App.
Templates are Marketing or Utility, approved by WhatsApp, and need a Manychat plan that includes them plus funds in your Wallet: see WhatsApp templates in Manychat (opens in a new tab).
Opt-in comes first
You can only message people who gave you their number and opted in to hear from you, per the WhatsApp Business Messaging Policy (opens in a new tab). A website form, an SMS or a phone flow can collect it (Meta’s opt-in guide (opens in a new tab)). Honor every opt-out.
US numbers: Marketing templates are paused
Meta paused Marketing templates to US numbers on April 1, 2025, with no end date confirmed. Utility templates and Click-to-WhatsApp ads still work (Manychat’s note (opens in a new tab)).

Chapter 05Budget
Plan the cost before a follow-up campaign
Three separate line items: your Manychat plan (WhatsApp starts on Pro, $39/month or $29/month billed yearly), WhatsApp message charges paid from your Wallet, and any AI layer you add, billed by its vendor.
Service messages are billed from October 1, 2026
Replies inside the window will be charged by destination, after 1,000 free service messages per phone number each calendar month, per Manychat’s WhatsApp pricing guide (opens in a new tab).
Before a campaign, write down these inputs, and redo the math after any policy or price change:

Test the failure path
A workflow is ready when these cases have predictable outcomes, not when the first happy-path reply looks natural.

Chapter 07Avoid
Common mistakes
Start from what the person asked, then ask one question that decides the next step.
Answer first. Collect only what changes the next action.
Count a booking only when the calendar event exists.
Use an approved template, with consent, or wait for the lead to write again.
Track qualified leads and confirmed calls instead.
Fix these in the workflow before you add more channels.
