Hello,
1) wordpress@ct.com is the default WP email address. Read this post if you want to change it https://www.wpbeginner.com/plugins/how-to-change-sender-name-in-outgoing-wordpress-email/
2) It was my manipulation to remove your previous account and create the new one with your correct email address. So, any third-party person. I have removed my temporary account, you can check the users’ list.
Regards
