This is a call to everyone who has a sufficient experience in any email verifying software. Your knowledge is precious for everyone!
Lately I have been experimenting with email grabbing (via SB) to compile niche lists, and then apply a lot of filtering to make them as relevant as possible. I then use Atomic Mail Verifier for the final verification. Then I upload the final list to my email delivery service (like MailChimp) and pray for good results and not getting banned.
Please have in…
