already exists vs is already existed

[harusbisa]

Dear teachers,

I want to ask about these statements that I found on the internet:
This email-user already exists.
This email-user is already existed.
I know that the first sentence is more common and grammatically correct.
But how about the second one (it is a bit like a passive voice?? but I find it weird to think of it as a passive since we can't put "by" after the "existed").
Please help me to understand this.
Thank you in advance.

"This email-user is already existed" is wrong.
