Is this plugin install contact form 7 too?

No. We have to install contact form 7 first and then we have to activate this plugin.


Works as expected

Installed easily and worked on test first go. Displayed error "Email address entered is not valid, DNS resolution failed." when using a fake address. Real address goes through without issue.
