The best thing about this software is that it helps me to send bulk emails in an organized manner which saves my time too! I have been using emailmeform for almost two years now, but there are some minor issues like sometimes when you try sending more than 10k mails then your server might get slow or even crash down completely due to high traffic of data being transferred over network/internet etc., But overall its one of those tools i can recommend without any hesitation as they deliver what exactly we need with no errors whatsoever!!
