Email template header from “WORDPRESS”

Hi,
if you are using Emails Module https://wpadverts.com/documentation/emails/ then you can set from wp-admin / Classifieds / Options / Emails panel the From header for each email individually.

Other than that to change the From header globally for all emails sent by WP you can use some third party plugin like https://ww.wp.xz.cn/plugins/wp-change-default-from-email/
