change of e-mail address

dear opentuition,
i just lost my previous email (jkdseebun@hotmail.com) and i want you to send all correspondences on my new one (kaseebun@hotmail.com).
My previous e-mail has hacked by someone else and i don’t want the hacker to view your correspondences addressed to me.

Please help, and give me a quick reply.
Thanking you for your support and understanding.
yours, kavit
