Note: This plugin only works with WordPress 4.2 or higher
This plugin will enable the site administrator to easily create an admin message present on all pages. The admin has the option to let the user dismiss the message for the duration of his session.

Admin User Message

I love to use it when a website is migrated over to a new host and the DNS propagation may take a lot to be updated. Editors need to know they should stop publishing for a while :)



Useful

This does just what I want. Thanks for making it. :)
It's definitely better than https://wordpress.org/plugins/admin-screen-messages
You might want to also tag it as:
https://wordpress.org/plugins/tags/admin-message



Perfect

Add message to users of your site. Choose wheter they can dismiss it or not.

Better Notifications for WP Support

Better Notifications for WP is a simple but powerful plugin for that allows you to customise the email notifications that WordPress sends using a WYSIWYG editor and shortcodes. All of the default WordPress email notifications are available to customise as well as lots of new ones. You can choose to send notifications to individual users, multiple users, all users in a user role, multiple roles – you name it! You can also power-up your notifications with <a href="https://betternotificationsforwp.com/downloads/" rel="nofollow ugc">Premium Add-ons</a>. Emails are sent out via your WordPress website (using <code>wp_mail</code>) but can be sent via SMTP using a 3rd party plugin should you wish. 
If you want to let users create their own email notifications/subscriptions/alerts, check out my other plugin: <a href="https://contentnotify.com" rel="nofollow ugc">Content Notify</a>.
Here’s a quick walkthrough of the plugin in action: 
<iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/MxPUyRZPJ1Q?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe>
<h4>An Example:</h4>
You want all the users in the Editor role to be notified via email when a new post is published and you’d like to customise it to include your logo along with the author’s name and date / time it was published – with this plugin, that’s easy.

A handy list of shortcodes you can use is available <a href="https://betternotificationsforwp.com/documentation/notifications/shortcodes/" title="Shortcodes for use in Better Notifications for WP" rel="nofollow ugc">here</a>.
