Hi, The issue here is some servers not correctly configured to send emails. So you need to change the email server. Use WP SMTP plugin this will resolve your issue
Wild guess: your SPF/DMARC/DKIM isn’t configured so outgoing emails are blocked.
Check DNS, email server settings and spam filters
For a quick fix you can use this plugin (I am a co-author with my friend developer and we have been using it on our sites when we want to change admin mail fast), until you setup some SMTP plugin for those mails: [https://wordpress.org/plugins/admin-email-address-changer/](https://wordpress.org/plugins/admin-email-address-changer/)
