Message Mate is a simple but wonderful slider add-on to your website that advertises a phone number which current and prospective customers can text with one click to reach you or your employees.
Your customers would rather text than call you. In fact, 76% of young adults prefer to interact with companies via texting (and not through calls, emails, live chat or contact forms). And thankfully for your business, texting is a more efficient and less distracting means of communication.
Texts also have much higher engagement potential with a 97% open rate, at least three times higher than email.
Up to three users can receive and respond to incoming messages via SMS, email, and a web dashboard. And you can even add automated responses and post-conversation rating requests.

This plugin is perfect for private message spam prevention. It allows site admin and users themselves to limit exactly who can send messages to the user.
This plugin creates an admin settings page called Restrict Messages. Here the site admin can choose to impose global restrictions over who can send messages to the user.
If message restrictions are delegated to the user, a user settings page is created at Profile>>Settings>>Messages.
Each of these settings pages, depending on which is active, allows private messaging to be restricted to:
<ul>
<li>Friend Connections</li>
<li>Follow Connections</li>
<li>Groups Connections – with further selection of public, private or hidden status levels.</li>
</ul>
The public setting allows connections from all groups to send messages to the user, otherwise private or public stipulate only messages from these types of groups.
Once a restriction has been implements, the plugin removes the private message from the users profile, removes the usename from the compose message send to auto-complete and rejects any messages send where the send to includes an excluded user.
This plugin was originally created by Rich @etivite and is now supported by Venutius.

Exactly what I needed to improve a situation on a client site's, and lovely to see @venutius supporting and maintaining this plugin! Thank you!

Does the job!
