How to send a campaign to a segment, once

Pick the segment, the message and the time. Boom sends it once to each person, lets the agent answer on WhatsApp and closes the campaign on its own when it's done. Step by step.

You want to tell your VIP customers about the Black Friday early access. Once, on Friday at 10:00, on WhatsApp. Someone who becomes a VIP next week shouldn't get a notice about an early access that's already over.

That's a campaign: one message per channel, to an audience, once. Here's how to set it up.

Before you start

  • A channel ready: a connected WhatsApp number, a verified email domain, or both.
  • A template per channel: a WhatsApp template approved by Meta or a published email template.
  • A segment with the people you want to reach. If it doesn't exist yet, create it in Segments.

Step 1: name and message

  1. Go to Campaigns and create a new one.
  2. In Name, use something you'll recognize in the report, for example Black Friday early access · VIP.
  3. In Message, pick the channel and its template. If you want both, add another message: email goes out first, then WhatsApp.
  4. Fill every template variable and open Preview to see it the way a real person from your audience would get it.

Step 2: who and when

In Who and when:

  1. Pick the segment as the audience.
  2. Decide when it's read:
    • Read at send time (the default): Boom reads the segment when the message goes out. Someone who already left it, say because they bought, doesn't get it.
    • Read now: Boom reads it when you schedule the campaign, and those people get it even if they leave the segment before the send.
  3. Pick Send now or a date and time.

The campaign never enrolls people who join the segment later. If every new person should get it, that's an initiative, not a campaign.

Step 3: replies and review (optional)

  • Replies go to the agent for 24 hours. With a WhatsApp message, whoever replies talks to the agent. Brief the agent lets you give it an objective, context, files or guiding questions. All optional.
  • Review before sending, under Delivery: every message waits in Drafts until someone approves it. Use it the first time you send to a large audience.

Step 4: schedule

Click Schedule. Nothing goes out before the time you picked. If you're not ready yet, Save draft keeps everything without scheduling.

What happens next

  1. At the time you picked, each person gets the message once.
  2. Whoever replies on WhatsApp talks with the agent for 24 hours.
  3. When the last conversation ends, the campaign becomes completed and its report is generated.

While it's open you can add people: if you add them after the send time, they get the message right away. Each person gets it once, even if you add them again.

Three common mistakes

  • Using a journey with a Segment entry for a one-time send. That journey keeps enrolling whoever enters the segment until you stop it. For a single send, use a campaign.
  • Variables with no value. If a variable comes from a field half your audience doesn't have, half of them get "Hi ,". Preview shows you before you send.
  • Sending all at once without reviewing. For your first campaign to thousands of people, turn on Review before sending and approve a sample.
