Snippet Library
Email snippets for WordPress
Snippets for the emails WordPress sends: change the sender name and address, add a Reply-To header, send HTML email and turn off notifications you do not need. For site owners who want their messages to arrive and look right.
Email When Plugin or Theme Updates Are Available
Checks once a day for plugin, theme and WordPress updates and emails the admin a list when there is something new to install, so outdated software does not linger.
Remove the [Site Name] Prefix From Email Subjects
Strips the "[Your Site Name]" WordPress puts at the start of its email subjects, which looks dated and wastes space on phones.
Send Admin Notifications to Several Addresses
Delivers emails addressed to the site admin email (new users, comments, updates) to additional team members as well.
Send Automatic Update Emails to Your Developer
Sends WordPress core, plugin and theme auto-update emails to your developer or agency instead of the site owner, who usually does not need them.
Stop Auto-Update Success Emails
Silences the emails sent after successful automatic updates of WordPress, plugins and themes. Emails about failed core updates are kept.
Stop Automatic Update Debug Emails
Stops the long technical "background update" debug emails WordPress sends after automatic updates on development, beta and nightly versions.
