I recently googled how to clear inbox of X recruiter emails. It was an interesting read about all the derogatory references to recruiters, but not terribly helpful.
Search your inbox by state references one at a time and delete all the emails. Most of jobs are concentrated on the east and left coasts so a few quick searches can hit a bulk of them.
There go about 10,000 emails….
Next you can search on Contract, H1B, Full Time
That should clear out a few 1,000
A search for Unsubscribe will probably hit most of the commercial emails.
You get the idea.
After a maybe an hours work you can get your inbox down to the personal emails you actually want to read.
I also use filters and labels as well as email rules to handle the volume of recruiter emails. Hopefully this has been helpful for someone.
