WhatsApp broadcast lists: how they work and when to use the API

What is a WhatsApp broadcast list

A broadcast list sends a message to selected contacts while replies continue in individual conversations. A group serves a different purpose: a shared discussion. Choose based on who needs the information and how your team will handle the response.

Traditional broadcasts, business broadcasts inside the app and API campaigns are different products. Organizing contacts into a list does not itself activate an API campaign platform.

Choose the appropriate workflow

Meta introduced paid business broadcasts in the app. Check the option available in your account before assuming a free service or a universal menu. Sources: broadcast list help and Meta’s announcement.

Prepare the audience before sending

1. Choose one purpose. A service update and a promotion need different preparation.
2. Select eligible recipients. Keep the source of consent and exclude people who have opted out.
3. Check the app’s current options. The Android help describes access from Chats or Tools. Names vary by version and country. The new Lists feature organizes contacts; sending is configured separately.
4. Write a clear next step. Identify the business, explain the reason for the message and check every date, condition and link.
5. Assign replies. Decide who will respond and what action follows an expression of interest.

Lists are rolling out gradually. Read the official Lists help to check your account’s workflow. For shared conversations, use the group invitation guide.

Why broadcast messages may not arrive

Identify the sending method first. For a traditional list, ask whether the recipient has saved your number. For business broadcasts, review the app’s notices. For API campaigns, inspect the available delivery status and error: prepared, sent and delivered are different states.

Before retrying, record affected recipients, timing and status. This helps separate an isolated case from a broader setup or audience issue. Resending to everyone can create duplicates for people who already received the message.

When to consider Piyion campaigns

An API workflow can connect segmentation, scheduling, team ownership and commercial follow-up. Start by documenting the audience, purpose, template, time, advisor and next action.

Explore official API campaigns, template examples and campaign costs in Colombia. Platform service and Meta messaging are separate cost components.

Measure replies and qualified opportunities

Choose the outcome before sending: a catalog request, a service confirmation or a sales conversation. Record the segment, date, delivered messages, responses and qualified opportunities. Reads are not sales.

Illustrative example: 12 conversations from 80 delivered messages represent a 15% response rate. If four meet your qualification criteria, record those separately. These are example numbers, not Piyion customer results. Consistent definitions make campaign comparisons meaningful.
