Skip paid enrichment when an interested lead already has a phone

When a reply is labeled Interested and a phone is already on file, Master Inbox labels it Call and alerts the rep, with no enrichment credits spent.

When

Add LabelInterested

Only if

Phone number is not empty

Then

Add labelsCall

And

Notify in SlackPost the phone and thread link to the rep's channel

Why teams run it

Saves credits and time, because signature numbers are often already in the thread.

Set it up in Master Inbox

In Master Inbox, open Settings, then Workflows, and click Add a workflow.
Name it Skip paid enrichment when an interested lead already has a phone.
Set the trigger to Add Label and choose Interested.
Add a condition: Phone number is not empty.
Add the action Add labels: Call.
Add the action Notify in Slack: Post the phone and thread link to the rep's channel.
Save the workflow and switch it to Active.

Before you start, connect Slack 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. This workflow also uses conditions: add them under trigger_config.conditions, as shown on the conditions page.

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 '{

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: "Skip paid enrichment when an interested lead already has a phone". 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

Where do existing numbers come from?

From your sequencer's lead data, or from Sales Intelligence reading the email signature.

What about leads with no phone?

Pair it with a workflow that runs phone enrichment when the phone is empty.

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.

Which plan includes this?

This workflow works on the Team plan. Every plan has unlimited users and starts with a free 7-day POC.
