I’ve managed to solve this issue! I did two things:
1) I saw there’s a ‘Move Followers from a WordPress.com Site’ option on Jetpack. So I moved my followers from theshoenazi.wordpress.com to theshoenazi.com.
2) I noticed that primary Site was pointing to theshoenazi.wordpress.com, so I changed it to theshoenazi.com
I published a test post and I got an email notif finally!
Sharing this, for everyone!
