Send a Microsoft Teams notification when a follow-up reminder is due
When a reminder on a positive lead falls due, Master Inbox posts it to Microsoft Teams with the prospect, the last message and a thread link, so the promised follow-up happens on time.

Why teams run it
Follow-ups promised on a call or in a reply stop slipping when the team lives in Teams, not in the inbox.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Send a Microsoft Teams notification when a follow-up reminder is due.
- Set the trigger to Due Reminder and choose Any reminder set by a rep or a workflow.
- Add a condition: Label sentiment is positive.
- Add the action Notify in Microsoft Teams: Post the prospect, last message and thread link to the rep's Teams channel.
- Save the workflow and switch it to Active.
Before you start, connect Microsoft Teams 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.
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" \

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: "Send a Microsoft Teams notification when a follow-up reminder is due". 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
Who sets the reminder?
A rep from the thread, or another workflow with the Set a reminder action. Keep it within 72 hours of the last message, because notifications skip threads that have been quiet longer.
Can I send it to Slack instead?
Yes. Swap the action for Notify in Slack. Everything else stays the same.
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.
