Text a prospect who missed the meeting to rebook

When a meeting is marked no-show and the lead has a phone, Master Inbox sends a friendly SMS with a rebook link from your Twilio number.

Why teams run it

A text gets seen faster than an email, and no-shows are easiest to rebook the same day.

Set it up in Master Inbox

  1. In Master Inbox, open Settings, then Workflows, and click Add a workflow.
  2. Name it Text a prospect who missed the meeting to rebook.
  3. Set the trigger to Meeting No-show and choose From Cal.com or Calendly.
  4. Add the action Send an SMS: Sorry we missed you, here is a link to pick a new time.
  5. Add the action Add labels: No-show.
  6. Save the workflow and switch it to Active.

Before you start, connect MI Inbox Dialer, 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": "Text a prospect who missed the meeting to rebook",
  "trigger_type": "meeting_no_show",
  "trigger_config": {},
  "action_configs": [
    {
      "action_type": "twilio_send_sms"
    },
    {
      "action_type": "add_labels",
      "label_ids": [
        176480
      ]
    }
  ]
}'

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: "Text a prospect who missed the meeting to rebook". 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

What if the lead has no phone number?

The SMS cannot send. The label still lets you follow up by email.

Is the SMS action live?

It is in beta and sends through your own Twilio account.

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.
