Philip Källberg reviewedEmail List Cleaner by MailSwiftClean email lists right in your browser for free
 RecommendedPros: 

Very easy, great results, runs 100% in browser

Cons: 

Not entirely sure how it scales - haven't tried any lists with 10k+ records

I've been using this to clean my email lists for a while, and it works great. It has reduced my bounces significantly and I love that it runs in the browser. In the privacy age it's great to know that I can control my own data locally.
