Resume the Smartlead campaign when an out-of-office reminder is due
When the 14-day reminder on an out-of-office lead falls due, Master Inbox resumes the lead in Smartlead and removes the Out of office label.

Why teams run it
OOO leads return to the cadence on time without anyone tracking dates.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Resume the Smartlead campaign when an out-of-office reminder is due.
- Set the trigger to Due Reminder and choose Reminder set when the lead was out of office.
- Add a condition: Label is Out of office.
- Add the action Resume in Smartlead: Resume the lead in the campaign.
- Add the action Remove labels: Out of office.
- Save the workflow and switch it to Active.
Before you start, connect Smartlead 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 \

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: "Resume the Smartlead campaign when an out-of-office 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
Will other reminders resume leads?
No. The label condition limits it to out-of-office leads.
What if they replied in the meantime?
Add a condition that the last message is from your team.
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.
