Email issue

The problem I am currently facing is that my bound email cannot receive any system emails (such as confirmation codes).
The reason may be that my previous email was disabled due to being idle, but I have now reapplied and successfully enabled it.
Unfortunately, I can no longer receive any system emails, which has resulted in me being unable to obtain confirmation codes to log in to the game.
This problem is very urgent for me and urgently needs support and solutions.
If you have any good suggestions, please let me know at any time. Thank you!
