Private messaging and email

Hi,

Was wondering if anyone was aware of a plugin that sends private messages to the user via email, and allows them to also reply via email.

Kinda of similar fashion to how Postmatic allows comments via email.

In a perfect world, I’d also like the user/admin private message inbox on the site to display in a similar way sms conversation as they display on most phones these days. The private messages using Ultimate Member plugin does this, as seen in this image: screen capture

Basically, on the site, it needs to display as a conversation thread as opposed to an email inbox with a separate entry for each message. That way, if you need to refer to something earlier in the conversation, you simply scroll up and down to find it, or search for a keyword within the content of the page to find what you need.

Any suggestions would be greatly appreciated. ??
