Email invites and responses can very quickly clog up your inbox. The following guide explains how to redirect or archive some of these. Be careful (if adapting this filter) not to accidentally filter out the invitations from others!
In Google Mail type the following in the search bar:
(subject:”declined:” OR subject:(“accepted:”) OR subject:(“maybe:”)) has:attachment invite.ics
Then click on the drop-down arrow to the right of the search box and select “Create filter with this search”
Tick or make a selection in the appropriate boxes and then click on “Create filter”.
All future email invitation responses will be filtered according to your settings.
