Flag quiet prospects for follow-up 24 hours after your reply
24 hours after a rep answers, if the prospect has not replied, Master Inbox adds a Follow-up needed label and moves the thread to the Follow-up list.
Why teams run it
Replaces snoozing threads in Gmail, so quiet prospects get a timely nudge.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Flag quiet prospects for follow-up 24 hours after your reply.
- Set the trigger to Sending Message and choose Your reply, 24 hours after it is sent.
- Add a condition: Last message is from your team.
- Add the action Add labels: Follow-up needed.
- Add the action Move to list: Follow-up.
- 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 \

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: "Flag quiet prospects for follow-up 24 hours after your reply". 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
Will it fire if the prospect answered?
No. If the prospect replied, the last message is theirs and the condition fails.
Can I use 48 hours instead?
Yes. Set the trigger delay to any value up to 30 days.
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.
