I like the import email address verification tool which identifies potentially bad email addresses and the ability to send mass bulk email to cold email addresses. I also like the ability to send from multiple domains.

MailClickConvert is a marketing system that allows us to send mass emails with advertising campaigns to as many customers as possible in order to attract traffic to our website in bulk and thus increase the profits of the company. We are happy because, in addition to that, we offer other types of features within its own panel a monitoring system that allows you to control the emails sent.

Not much. The UI is not bad, but the deliverablity rate was so low it defeats the entire purpose of the software.
