Set a reminder when a rep opens a hot reply but does not answer it
When an interested reply is opened in Master Inbox and the prospect still has the last word, a two-hour reminder is set, so read but unanswered positives come back.
Why teams run it
Opened threads feel handled even when nobody replied. This closes that gap.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Set a reminder when a rep opens a hot reply but does not answer it.
- Set the trigger to Message Seen and choose All channels.
- Add a condition: Label is Interested.
- Add a condition: Last message is from the prospect.
- Add the action Set a reminder: In 2 hours.
- 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.

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: "Set a reminder when a rep opens a hot reply but does not answer it". 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
Why use Message Seen?
It fires when someone opens the message in Master Inbox, which is when a lead is most likely to be forgotten.
Can it alert instead of reminding?
Yes. Use a Due Reminder workflow to post the reminder to Slack.
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.
