If you delete a user while he/she is still part of an active Monitor pairing, the monitoring user will continue to receive emails; this is because monitoring triggers are stored within Google's system. To remove this pairing, please complete the following steps:
1. Re-create/re-activate the user
2. Re-create the pairing in BetterCloud
3. Delete the pairing in BetterCloud
4. Delete the user once more
You will no longer receive messages.
If you have removed the BetterCloud app from your domain and are still receiving email monitors, you must re-install BetterCloud, recreate the pairing, and remove the pairing.
