Find the email address for LinkedIn replies before handing them to sales

When a HeyReach LinkedIn reply comes in from a lead with no email, Master Inbox runs contact enrichment, so the AE can follow up by email and the CRM gets a usable record.

Why teams run it

LinkedIn conversations stall when nobody has an email to send the invite to.

Set it up in Master Inbox

In Master Inbox, open Settings, then Workflows, and click Add a workflow.
Name it Find the email address for LinkedIn replies before handing them to sales.
Set the trigger to Incoming Message and choose HeyReach and LinkedIn channels.
Add a condition: Email is empty.
Add the action Enrich the prospect: Contact enrichment waterfall.
Save the workflow and switch it to Active.

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 '{
  "name": "Find the email address for LinkedIn replies before handing them to sales",
  "trigger_type": "incoming_message",
  "trigger_config": {
    "channel_ids": [
      "-1"
    ]
  },
  "action_configs": [

      "action_type": "enrich_prospect",
      "enrich_with": "contact_enrichment_bundle"
    }
  ]
}'

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: "Find the email address for LinkedIn replies before handing them to sales". 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.
