Labelizer for Gsuite is best for managing emails such as archiving, filtering, creating groups, etc. Since I use Gmail professionally at work, and also for personal use, it helps me stay focused and efficient. By default, Gmail has limited features and this add-on is definitely beneficial. Review collected by and hosted on G2.com.

As mentioned before, as this is an add-on, many organizations will not allow external add-ons to be enabled on their systems. This had to go through approvals and IT process to get installed which is a pain. Review collected by and hosted on G2.com.
