A clear email request can prompt Notis to refresh the named sandbox and extend its time to live.
Trigger

Triggers when a new message is received in Gmail.
Action
Refresh Sandbox
Tool to refresh an E2B sandbox and extend its time to live. Use when you need to keep a sandbox alive longer and prevent it from timing out.
Why this helps
An environment needed for ongoing work may time out while a request to keep it alive waits for attention.
- Respond to explicit keep-alive requests.
- Extend the named sandbox's time to live.
- Reduce manual checking and refresh steps.
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 refresh only when a message clearly requests it and includes a sandbox ID.
- 4Pick the New Gmail Message Received trigger and choose where run reports go.
- 5Test with one real keep-alive email for a sandbox you can safely refresh.
Questions about this workflow
Does refresh change the sandbox timeout to a chosen duration?
Refresh extends the sandbox time to live. Use Set Sandbox Timeout if you need to specify a timeout duration.
What if the email does not name the sandbox?
Tell Notis to request the missing sandbox ID rather than guessing.
