Get a Slack alert when someone from a target account replies
When a reply comes from a domain on your target account list, Master Inbox posts it to an ABM channel in Slack, whatever the label, so the account owner sees every touch.

Account-based plays fail when a reply from a key account is treated like any other.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Get a Slack alert when someone from a target account replies.
- Set the trigger to Incoming Message and choose All channels.
- Add a condition: Domain is one of your target account domains.
- Add the action Notify in Slack: Post the prospect, company, reply and thread link to #abm.
- 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.
