Email Listeners

I’m experimenting with Foundry Email Listeners (they are cool)

One thing I’m unsure about: after I start/trigger the listener, the build appears to keep running continuously, which I assume is because it is acting as a listener rather than a normal finite build.

Is that expected behavior for Email Listeners? Or is there anything I should monitor / worry about, such as cost, stuck builds, resource usage, or misconfiguration?

Yes, that’s expected. Email Listeners run continuously by design, they stay alive to watch for incoming emails rather than completing like a normal build.

Things to monitor:

Stuck builds: If an unhandled exception occurs, it may stall silently. Check execution logs periodically.
Resource usage: Keep an eye on the Build Management panel, especially if running multiple listeners.
Trigger scope: Make sure your email conditions are well-scoped to avoid unintended high-frequency triggers.

Otherwise, no red flags.
