Check in 2 days after sending pricing if the prospect goes quiet
Two days after your team answers a Pricing or Information request, if the prospect has not replied, Master Inbox labels the thread Check in and pings the rep in Slack.

Why teams run it
Deals stall right after pricing goes out, and a timely check-in keeps them moving.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Check in 2 days after sending pricing if the prospect goes quiet.
- Set the trigger to Sending Message and choose Your reply, 48 hours after it is sent.
- Add a condition: Label is Pricing or Information request.
- Add a condition: Last message is from your team.
- Add the action Add labels: Check in.
- Add the action Notify in Slack: Post the prospect 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.

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: "Check in 2 days after sending pricing if the prospect goes quiet". 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
Can the AI draft the check-in?
Yes. Scope a reply agent to the Check in label in human-in-the-loop mode.
Why not wait longer?
Slack, email and webhook notifications skip threads whose last message is older than 72 hours, so keep the delay under that.
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.
