# How to Send a Broadcast Using Multiple WhatsApp Numbers

Normally, when you send a broadcast, it goes out from a single WhatsApp number. With the **Send from Multiple WhatsApp Numbers** feature, DoubleTick can automatically send each message from a specific number assigned to that contact — allowing you to broadcast at scale across several WhatsApp Business Accounts (WABAs) at once.

This is especially useful for businesses that manage multiple regional numbers, different product lines, or want to distribute message volume across accounts to improve deliverability.

Before sending a broadcast from multiple WhatsApp numbers, DoubleTick needs to know which WhatsApp number should be used for each contact. You can set this up in one of two ways.

**Option 1 — Create a Custom Customer Field**

Create a custom customer attribute (for example, "Multiple WABA Broadcast") where you will store the WhatsApp number assigned to each customer.

**Option 2 — Update Your Customer Data via Excel Import**

1. Export or prepare your customer list in Excel.
2. Add a new column with a name like "Multiple WABA Broadcast."
3. For each customer, enter the WhatsApp number from which you want the broadcast to be sent.
4. Save the file and re-import it into DoubleTick.
5. During import, map the new column to your custom customer field.

Once imported, DoubleTick will store this information against each customer profile and use it when sending the broadcast.

**Example:**

| Customer Name | Phone Number  | Multiple WABA Broadcast |
| ------------- | ------------- | ----------------------- |
| Rahul Sharma  | +91XXXXXXXXXX | +91 9876543210          |
| Priya Patel   | +91XXXXXXXXXX | +91 9123456789          |
| Amit Shah     | +91XXXXXXXXXX | +91 9988776655          |

Each customer will receive the broadcast from the WhatsApp number specified in the Multiple WABA Broadcast column.

If this field is not populated for a customer, DoubleTick will use the backup WhatsApp number you select during broadcast setup (covered in Step 6 below).

<figure><img src="/files/KgRM3Hdl4el4jiUSwrF1" alt=""><figcaption></figcaption></figure>

#### <mark style="color:$primary;">**Step 1 — Go to Broadcast Lists**</mark>

From the left sidebar, click the **Broadcast** icon to open your **Broadcast Lists** page. Select the broadcast list you want to send to, or create a new one.

#### <mark style="color:$primary;">**Step 2 — Click "Send WhatsApp Template"**</mark>

At the bottom right of the screen, click the green **"Send WhatsApp Template"** button. This opens the **Templates** dialog showing all your approved message templates.

#### <mark style="color:$primary;">**Step 3 — Find and Click "Send" on a Template**</mark>

Browse or search for the template you want to send. Templates approved across multiple WhatsApp numbers will show a badge like **"3 WABAs"** next to the template name, indicating how many numbers that template is approved for.

Click the green **"Send"** button on the template you want to use.

#### <mark style="color:$primary;">**Step 4 — Switch to "Multiple WhatsApp Numbers" Mode**</mark>

The **Send Template** dialog will open. By default, it shows a **"Send broadcast via"** dropdown — this is the single-number mode. To use multiple numbers, click the green link that says:

**"or send from multiple WhatsApp numbers"**

The dialog will switch to multi-number mode.

#### <mark style="color:$primary;">**Step 5 — Select the Customer Field**</mark>

You will now see a section called **"Select customer field to send from multiple numbers."** This dropdown lets you choose which contact attribute tells DoubleTick which number to use for each customer.

You have two types of options:

**Default Fields:**

* **Last contacted on number** — DoubleTick sends from the same WhatsApp number that last messaged that customer. This is the easiest option if your team already uses different numbers for different contacts and no extra setup is needed.

**Customer Attributes:**

* Any custom attribute you have created (for example, "Multiple WABA Broadcast") — this uses the number you assigned to each contact during the setup above.

Select the field that matches how your contacts are set up.

#### <mark style="color:$primary;">**Step 6 — Check Coverage and Set a Backup Number**</mark>

After selecting a field, DoubleTick will check your contact list and show one of two statuses:

* **"All customers have this field set"** — every contact has a value assigned, so every message has a sending number.
* A warning if some contacts are missing a value.

Below the status indicator, select a **backup API number** from the dropdown. This is the WhatsApp number DoubleTick will use for any contacts whose field is missing or if delivery fails. Always select a reliable number here.

#### <mark style="color:$primary;">**Step 7 — Click "Next"**</mark>

Once you have selected your field and backup number, click the **"Next"** button in the bottom right.

#### <mark style="color:$primary;">**Step 8 — Send Now or Schedule for Later**</mark>

A final confirmation dialog will show how many customers the broadcast will reach. Choose one of the following:

* **Send now** — The broadcast goes out immediately.
* **Send Later** — Schedule it for a specific date and time.

#### <mark style="color:$primary;">**Tips and Things to Keep in Mind**</mark>

**Prepare your contact list before starting.** If you are using a custom attribute like "Multiple WABA Broadcast," make sure your spreadsheet includes a column with the correct WhatsApp number for each contact before you import it. Without this, those contacts will not have a sending number assigned.

**Use "Last contacted on number" for simplicity.** If your agents already reply to customers from specific numbers, this default field requires no extra spreadsheet setup.

**Always set a backup number.** Even if all your contacts have a field value, message delivery can occasionally fail. A backup number ensures no contact is missed.
