I like how smoothly it integrates email marketing directly into WordPress, you can make lead capture forms and popups that feed into the system, and then send emails automatically or schedule one off newsletters. Review collected by and hosted on G2.com.

I recently got told my account might get banned, very OTT reaction. Turns out a link I'd included to a source website was to a site on some banned list (how would I even know that?!). Support also went on about using shortlinks in the email. I hadn't used shortlinks. Review collected by and hosted on G2.com.
