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.
Remove the X-Mailer Header From Emails
Stops outgoing emails announcing "PHPMailer" and its version in the X-Mailer header, which reveals details about your server and can count against you in spam filters.
Stop Automatic Update Debug Emails
Stops the long technical "background update" debug emails WordPress sends after automatic updates on development, beta and nightly versions.
