This plugin for WordPress MU is really simple. It allows site administrators to send a (plain text) to all users. You can type in the subject and text for the email, and it will try to send it to all user email addresses in the database.
That’s pretty much it.
There are two small additional features with this plugin. Firstly if any emails fail to be sent the failing email addresses will be shown in a list, so you can decide what to do. Secondly there is a “Test” checkbox, which when checked will only send the newsletter to the site admin email address.
If you have a lot of users this plugin may take a long while to run, as it sends a separate email for each user. There is some reasoning behind that: in the future I may write in some special codes that you can use in your emails that will insert the users email address (so they can unsubscribe, for instance), a link to their wp-admin folder, and more user-specific data. That stuff is pretty much impossible to do if you use BCC to send one email to multiple people.

Sitewide Newsletters

Sitewide Newsletters is a Wordpress MU plugin that allows site administrators to send an email message to all users.

Personal welcome is a WordPress/MultiSite/BuddyPress plugin that lists newly registered users, and allows site administrators to send them a personalised welcome message. The welcome messages are based on templates which you can write yourself (as many templates as you like). Once a message is sent that user won’t appear again.
There are four extra management features:
<ul>
<li>The ability to set all users as having been sent a welcome message (an easy way to bulk remove everyone from the list, for example when the plugin is first installed)</li>
<li>The ability to search for a user and send them a welcome message</li>
<li>The ability to set the new user as being spam</li>
<li>The ability to set the new user and all their blogs as spam</li>
</ul>
Of course, the templates don’t have to be just for welcoming people – they could contain FAQs, help information or anything else.
The plugin also makes use of the __() function to allow for easy translation.
