Review for Sender Frequency by Gralth
Rated 5 out of 5 stars
Absolutely fantastic add-on that is extremely useful for keeping my inbox manageable. I use it to identify common "daily" spam emails that I get and rapidly select all and delete them if I am not interested at the time, but don't necessarily want to unsubscribe. Hopefully the API fix goes through and this can be compatible with 115 soon!
This review is for a previous version of the add-on (2.0.5).To create your own collections, you must have a Mozilla Add-ons account.
