Best tool to scrape emails?

Hello,
I got 2k url's that i got from ahrefs with websites who have my 2 main keywords.

Im with a new mission to scrape those emails and send them cold emails.

Whats the best tool and faster or easyer to scrape those 2k websites?
I use Hunter.io but i think this tool dont fit for this big job.

Any idea of tools to scrape those 2k websites?

Hi,
WebHarvy is simple and have fast learning curve.
Using a programming langage like ruby is more powerfull, free but longer learning curve
