Niche Emails

Hey, as the title says i need emails of people working in leading positions in certain niche businesses like cleaning companies etc

WH and BH are both welcome. Paid or free, a fast method would be good.

Buying from someone/software, doesn't really matter as long as i can get most of the emails from CEO/cfo etc in these biz's

USA only

Any suggestions?

Use LinkedIn in combination with the Hunter.io plugin.

GMass if you need to send bulk emails. Have fun. Thank me later
