I translated Japanese into English.
Please check.
The following is a question.
I added a new user, but I did not receive a confirmation email and cannot log in.
I tried resubmitting but did not receive the email.
I had registered the wrong email address the first time and did not receive the confirmation email.
I then registered the correct email address, but to no avail.
After checking, there is a possibility that the email is on the "suppression list" and I contacted you.
Could you please check if it is registered in the suppression list?
