How to change the FROM address for MainWP emails

By default, MainWP uses the Administration Email Address from your WordPress General Settings for email notifications. You can change the FROM address specifically for MainWP emails without modifying that WordPress setting.

Add the PHP code

Go to the PHP tab and add this code:

add_filter( 'mainwp_send_mail_from_header', 'myhook_mainwp_send_mail_from_header', 10, 3 );
function myhook_mainwp_send_mail_from_header( $input, $email, $subject ) {
    return array(
        'from_name'  => 'Your Name',
        'from_email' => 'your-email@example.com',
    );
}

Customize the values

Replace the placeholder values:

'Your Name' - The sender name recipients will see
'your-email@example.com' - The email address to send from

Save changes

Click Save Changes. All MainWP emails now use your custom FROM address.

Change FROM Address for Specific Emails Only

To customize the sender only for certain MainWP emails (e.g., Daily Digest), use this conditional version:

add_filter( 'mainwp_send_mail_from_header', 'myhook_mainwp_send_mail_from_header', 10, 3 );
function myhook_mainwp_send_mail_from_header( $input, $email, $subject ) {
    // Only change FROM for specific email/subject combinations
    if ( 'recipient@example.com' == $email && 'Daily Digest' == $subject ) {
        return array(
            'from_name'  => 'Custom Name',
            'from_email' => 'custom@example.com',
        );
    }
    // Return original for all other emails
    return $input;
}

Adjust the $email and $subject conditions to match the emails you want to customize.
