Recover no-shows with a reminder and a Smartlead rebook campaign

When a meeting is marked no-show, Master Inbox labels the lead No-show, sets a reminder for tomorrow and adds them to a Smartlead rebook campaign, so missed meetings get a second chance.

Why teams run it

No-shows are often busy, not lost, and most were never followed up when this was manual.

Set it up in Master Inbox

  1. In Master Inbox, open Settings, then Workflows, and click Add a workflow.
  2. Name it Recover no-shows with a reminder and a Smartlead rebook campaign.
  3. Set the trigger to Meeting No-show and choose From Cal.com or Calendly.
  4. Add the action Add labels: No-show.
  5. Add the action Set a reminder: Tomorrow, so the owner checks the rebook.
  6. Add the action Add to Smartlead campaign: Rebook campaign.
  7. Save the workflow and switch it to Active.

Before you start, connect Smartlead, Cal.com or Calendly under Settings, Integrations.

Or create it with the API

Everything in the workflow builder is also in the Master Inbox API. This request creates the same workflow. Replace the example ids with your own label, list and campaign ids from GET /workflows/filter-fields.

curl -X POST https://api.masterinbox.com/api/api-webhook/v1/api/workflows/create-workflow \
  -H "Authorization: Bearer $MASTER_INBOX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "name": "Recover no-shows with a reminder and a Smartlead rebook campaign",
  "trigger_type": "meeting_no_show",
  "trigger_config": {},
  "action_configs": [

Or ask Claude, ChatGPT or Grok to build it

Our workflow guide is written for AI agents to read. Give your assistant your API key and this prompt:

Read https://app.masterinbox.com/public-workflow-api.md and use my Master Inbox API key to create this workflow: "Recover no-shows with a reminder and a Smartlead rebook campaign". First call GET /workflows/filter-fields and look up my label, list and channel ids, then create the workflow and tell me what you set up.

Questions

How is a no-show detected?

The trigger fires when the meeting is marked no-show on the Meetings page or by the calendar's status.

What should the rebook campaign say?

Keep it short and easy: one line that you missed each other and a link to pick a new time.

Can I build this workflow through the API?

Yes. Send the create-workflow request shown on this page with your Master Inbox API key. The API checks the payload first and lists every problem by field if anything is off.
