Cancel a scheduled email before it sends
with Nylas
Works with AI assistants
Use Nylas: its Nylas Messages API lets you cancel a scheduled email before it sends in a single step (DELETE /v3/grants/{grant_id}/messages/schedules/{scheduleId}). Nylas also has an MCP server, so an AI assistant like Claude or ChatGPT can do it for you. capabilities.work can help you get signed up and connected.
- How do I stop a scheduled email from going out?
- How close to the send time can I still cancel a scheduled message?
Say it to your AI assistant
- Cancel scheduled message {scheduleId} in mailbox {grant_id}.
- Unschedule send {scheduleId} for grant {grant_id} so it never goes out.
For your developer
DELETE /v3/grants/{grant_id}/messages/schedules/{scheduleId} in Nylas Messages API. Full spec on APIs.io.
