Best mail checker tool on the market by far

We used and are still using Bouncer service to bulk verify mail adresses validity, so that our cold mail campaigns are more likely to be successful! Bouncer service is very efficient and fast! In a few minutes, it gives you all the unknown, unexistant and dangerous mail addresses from a list you give the tool. That way, you can clear a list very quickly and save a huge amount of time. We definitely recommend Bouncer for every company or person willing to reach people through mail and wanting to check the validity of their list.
