Free Fire OTP Emails Stopped After Unsubscribing Garena Gmail Sender

I am facing a serious problem with my Garena Free Fire account on my Android device, which is linked to the email address kktah***[email protected]. On 3 June 2026, I accidentally unsubscribed from the sender address [email protected] in Gmail. I did not know that unsubscribing from this sender would block important OTP emails. As a result, I have completely stopped receiving OTP codes and I am no longer able to log in to my Free Fire account. Since the day I unsubscribed, I have not received a single OTP message and I am unable to access my account at all. This situation is causing me a lot of difficulty because my game progress is stuck and I cannot use my account in any way. This was an unintentional mistake, and if I had known that OTP emails would be blocked, I would never have pressed unsubscribe. I kindly request that my email address be re-subscribed and reactivated for OTP delivery so that I can start receiving OTP codes again and log back into my Free Fire account. I would be very grateful if you could restore the email subscription or give the necessary permission so that OTP emails from Garena are delivered to my inbox again as soon as possible.
