Campaigns (bulk messaging)

In Campaigns you send the same message to many people at once — a promotion, a notice or a reminder. Campaigns use the Official API (WABA) and an approved template, which is the safe, Meta-approved way to send bulk messages.

Before you start

You will need:

1. A connected Official API instance. See Connect your WhatsApp.
2. An approved template. See Message templates.
3. A CSV spreadsheet with the numbers.

How to build the spreadsheet

• The first row is the header.
• A required column called phone, with numbers including country and area code, digits only (e.g. 15551234567).
• If the template has variables, create columns called 1, 2... They fill {{1}}, {{2}}... in the template.

Example (for the template "Hi {{1}}, your appointment is on {{2}}"):

phone,1,2
15550000001,Mary,Oct 12 at 2pm
15550000002,Charles,Oct 13 at 9am

In Excel or Google Sheets, use File › Save as / Download › CSV.

Create a campaign

1. Click Create Campaign.
2. Details: give it a Campaign Name and choose the Sender Instance (WABA Only). Click Next.
3. Leads: click Click to upload CSV and pick your spreadsheet. The system shows how many contacts were loaded. Click Next.
4. Content: choose the template in Select Template and check the preview.
5. Click Finish & Create.

Send it

The campaign is created as a draft (DRAFT). In the campaign list, click Start Now to begin sending. The system sends in batches, in the background — you can close the page.

Track the results

• Total Leads, Sent Successfully and Failed.
• The list of each phone with status Sent, Pending or Failed, and the error reason under Details / Error Log.

Good practices

• Only send to people who agreed to receive messages from your business.
• Start with smaller lists: Meta unlocks higher daily limits (1k, 10k, 100k contacts per day) as your number's quality improves.
• Common errors: invalid number or no WhatsApp, paused/rejected template and Meta daily limit reached.
