Welcome to the forum @bd8392
If you’re trying to get a previous poster’s attention, especially awhile later, using the Reply button on a particular post will do better than the Reply button for the topic at the bottom (which won’t send email).
Mentions like the following also work, but if @Igor_Goloma is unable to help, another method may be Apprise - Push Notifications that work with just about every platform! as now supported by dupReport.
Announcing dupReport - A Duplicati Email Report Summary Generator will discuss this third-party tool.
Notify_telegram is the Apprise page on Telegram Notifications.
