Hello @raltok,
Thank you for reaching out to us.
P?lease try installing Mail Logging plugin https://www.ads-software.com/plugins/wp-mail-logging/ on your website. It will add a log entry each time the wp_mail() WordPress function is called (our plugins use this function for all of the emails they send).
You will then be able to go to the Email Log page on your website’s Dashboard to see if the email is being sent after you test this.
If it is listed there then there is a good chance there are filters set up on the server that might block some outgoing emails and I would suggest you contact your web hosting provider and ask them if this is the case.
Best Regards,
Paul
