In their words
Their pitchVerify email address for free mail service such as Gmail, Yahoo!, AOL, Mail.ru etc. In many cases, it is perfectly acceptable to send email to a user of a free email service. However, in certain contexts, businesses can receive better open/response rates when only sending to non-free / business email addresses
