Send from on Email- how do I overwrite WordPress as Sender

You can overwrite this by modifying the functions.php file that is located within your theme.

This file can be accessed via Appearance ->Editor and look for Theme functions OR by FTP wp-content/themes/whatevertheme/functions.php

Add the following (but modify “admin@domainaddress.com” and “Your Blog” to match what you want the display email address and ‘from’ field to show)

add_filter('wp_mail_from', 'new_mail_from');
add_filter('wp_mail_from_name', 'new_mail_from_name');

function new_mail_from($old) {
 return 'admin@domainaddress.com';
}
function new_mail_from_name($old) {
 return 'Your Blog';
}
