We are currently using rightmessage to create CTA popup widgets on our website. So far so good. We would need to embed rightmessage code in to our website and the code is light and clean. So it doesn't affect the load time. afterall, it is just a popup. With the popup, we are able to collect emails and as well as display message and announcement. It can either be a popup, a full screen, a sidebar or even embed it within the article in between the paragraph.

I love how easy it is to customize your site based on who is viewing it.
