Maybe try dropping the " @chess.com"> " from the email address.
Chess.com account support mailbox is undeliverable
well, that seems weird because I'm simply "replying" to the original email. You'd assume the mailbox was correct. I've tried @chess.com">accounts@chess.com and @chess.com">account@chess.com from a different email system and they both still bounce back.
No link in the email body. This is exact wording:
"We are always sad when we close any account. We want everyone to be able to enjoy chess. However, we must protect the experience of all of our members, and cannot allow players to repeatedly stall, quit, or otherwise create a negative experience for their opponent. We hope you understand that we work hard to keep Chess.com a safe, fair, and positive community for chess players around the world.
We would like to offer you the chance to re-open your account if you can respond to us and acknowledge the terms that you have violated. Please let us know if you are interested in re-opening your account, along with an acknowledgement of the policies and why your account was closed."
For the record, I got into it verbally with a player during a tournament. But there's not link meaning the only option is to "reply". If you hit reply the only email account that populates is 'noreply@chess.com ' clearly that wont work. So you can go with account or @chess.com">accounts@chess.com
Any mods on this forum have any ideas or advice??

Staff are looking into why the wrong email was sent. You should contact Support directly using the option in the menu instead
I got a closed account email from Chess.com support with the option of 'reply acknowledging you offense and the account would be considered for reactivation". However, every reply I send to @chess.com">accounts@chess.com or @chess.com">account@chess.com gets bounced back as undeliverable. When I use the support bot it simply tells me to follow the options laid out in the original email. I'm caught in a loop. Anyone else have this issue or know the correct mailbox I'm supposed to respond too? Thanks!
