apply_filters( ‘wp_mail_from’, string $from_email )

Filters the email address to send from.


Email address to send from.

More Information

  • The wp_mail_from filter modifies the “from email address” used in an email sent using the wp_mail() function. When used together with the ‘wp_mail_from_name‘ filter, it creates a from address like “Name”. The filter should return an email address.
  • To avoid your email being marked as spam, it is highly recommended that your “from” domain match your website.
  • Some hosts may require that your “from” address be a legitimate address.
  • If you apply your filter using an anonymous function, you cannot remove it using remove_filter() .


$from_email = apply_filters( 'wp_mail_from', $from_email );
