Questions, answered

Will it send the reply for me?

No. WebRun only drafts a reply and leaves it unsent in Posteo. You read it, edit it if needed, and hit send yourself.

How does it decide a thread is stale?

It checks whether the last message in the thread is from someone else and how many days have passed, using the 3 day threshold you set.

What happens once I reply?

The next run sees your reply as the latest message, so the thread drops off the chase list and its calendar reminder can be removed.

Put this on autopilot.
