Pause an E2B sandbox from an email request
When a clear request arrives, let Notis suspend the specified sandbox while preserving its state.
Trigger
New Gmail Message Received Trigger
Triggers when a new message is received in Gmail.
Action
Pause Sandbox
Tool to pause a running E2B sandbox preserving its filesystem and memory state. Use when you need to temporarily suspend a sandbox while maintaining its state for later resumption. Takes approximately 4 seconds per 1 GiB of RAM to pause. Paused sandboxes can be stored for up to 30 days.
Why this helps
A sandbox can keep running because a pause request is waiting in an inbox.
- Act on explicit pause requests as they arrive.
- Preserve sandbox filesystem and memory state.
- Avoid a separate manual handoff to E2B.
Setup
Build it in a few focused steps.
- 1Connect Gmail and E2B once in the Notis portal.
- 2Create an automation and give it a clear name.
- 3Tell Notis to pause only when the message clearly requests it and provides a sandbox ID.
- 4Pick the New Gmail Message Received trigger and choose where run reports go.
- 5Test with one real pause request for a sandbox you can safely pause.
Questions about this workflow
Can the sandbox be resumed later?
Paused sandboxes preserve their state for later resumption, subject to E2B's sandbox limits.
What happens if the request is ambiguous?
Tell Notis to seek clarification instead of pausing a sandbox based on an unclear request.
