Send reach out next quarter replies to a Smartlead subsequence
When a prospect asks you to come back later and the reply is labeled Future, Master Inbox moves them into a Smartlead follow-up subsequence timed for next quarter.

Why teams run it
You keep the promise to follow up later without a spreadsheet of dates.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Send reach out next quarter replies to a Smartlead subsequence.
- Set the trigger to Add Label and choose Future.
- Add the action Move to Smartlead subsequence: Next quarter follow-up subsequence.
- Save the workflow and switch it to Active.
Before you start, connect Smartlead under Settings, Integrations.
