Sending a WhatsApp Campaign in Mumble

In short: A campaign in Mumble takes three steps: create a template and get it approved by Meta, put opted-in customers in a list, and send. Campaigns always use an approved template, because most recipients have not written to you in the last 24 hours.

Before you start

• Opt-in: send only to people who agreed to get WhatsApp messages from you. Bought lists and phone contacts do not count. See Opt-Out and Blacklist.
• Payment method at Meta: Meta charges for every delivered template, separately from your Mumble plan. See Paying Meta and WhatsApp Messaging Costs.
• Plan: campaigns are available from the Pro plan.

Step 1: Create a template

1. Go to Templates and click +.
2. Enter a name: lowercase English letters, numbers and underscores, for example summer_sale.
3. Choose the category: Marketing for promotions, Utility for updates about something the customer did.
4. Choose one language and write the text. Add variables like {{1}} inside sentences, not at the start or end.
5. Add buttons if needed. In Marketing templates, add an opt-out button from the opt-out word picker.
6. Save. Meta answers within minutes, and at most about 24 hours.

Templates cannot be edited. If one is rejected, delete it and create a new one with a new name. See Creating a WhatsApp Message Template.

Step 2: Import customers into a list

1. Go to Customers, click + and download the Sample file.
2. Fill in the customers. Put the list name in label_name.
3. Enter phone numbers in full international format with no + (972501234567), or as local numbers with a two-letter country code like IL in country_code.
4. Click + > Import new customers and match the columns.

Step 3: Send the campaign

1. Go to Campaigns, click + and choose an approved template. You can also click the template’s name on the Templates page.
2. Enter a campaign name you will recognize in reports, for example black_friday_2026.
3. Optional: choose a campaign bot to answer replies.
4. Optional: add actions for every recipient, like adding them to a list, changing their status, or assigning an agent.
5. Choose who gets it: one or more lists, or specific customers. You can also exclude lists.
6. Fill the variables: free text for everyone, or a customer field like first name.
7. Send now, or schedule a date and time. The time you pick is your computer’s local time.

• A customer in several lists gets the message once.
• Customers who opted out are skipped.
• A scheduled campaign can be cancelled, not edited.

Limits

Three limits apply, and the lowest one wins:

• Your Mumble plan’s monthly template quota. When it runs out, campaigns will not start.
• Meta’s messaging limit on unique customers per 24 hours.
• Meta’s per-person limit on marketing messages (error 131049). US (+1) numbers do not get Marketing templates.

Common questions

Some customers did not get the message

Open the campaign report and check the failed recipients. Usually the phone format is wrong or the number has no WhatsApp. See Campaign Troubleshooting.

Where do I see the results?

Click the campaign name on the Campaigns page. You see delivery status per customer, button clicks, an estimated Meta cost, and the golden hour when most people opened it. See Reading Your Campaign Results.

A scheduled campaign sent nothing

The list was probably empty at send time. Check the list before the scheduled time.

How do I make the message personal?

Use variables filled from customer fields, like first name or an order number added in the import file. See Dynamic Variables and Post-Send Actions.
