Prevent Gmail from delivering emails of a thread to the inbox once a label is applied to it

Question

I have a lot of emails to which I apply labels and remove it from the Inbox. However, when a new email in the thread arrives, it again comes to my Inbox (and is also in that label's folder). How do I prevent it from coming it to the inbox? Please note that many a times, there are no specific rules for these (when I do give rules however, I say skip the inbox but otherwise, how to do?)

Answer 1

You can use Gmail's Muting feature to automatically have subsequent messages bypass the inbox, but that won't automatically apply the label. For that, you would need to create a filter action based on the subject line.
