I receive other people's email

Check the address shown in the To field of these messages.

If your address contains a hyphen but you receive email for an address with a dot, or vice versa, the messages are probably yours, not someone else's.

Yandex.Mail doesn't distinguish between dots and hyphens in email addresses. These are aliases — synonymous addresses for the same mailbox. They always belong to the same recipient. For example, if you registered my-address@yandex.com, you can also send and receive emails with my.address@yandex.com. No one else can use either of these addresses.

If your address contains uppercase letters but you get email meant for the same address with lowercase letters (or vice versa), the messages are probably meant for you.

If you're receiving emails from an address you don't recognize, there could be several reasons:

Sender error when providing the address of the recipient

If you received a message from an unknown sender, the sender may have made a mistake when specifying the address of the recipient. You can inform the sender of the mistake or just ignore the email.

Someone registered on a website using your email address as a contact
Some websites allow registration without email confirmation. This means that people can enter an email address that is not theirs. Even if someone enters your address on a website, they can't use your mailbox. If you don't want to receive email from this site:
  1. Add the sender's address to the Blacklist.
  2. Contact the website administrator and inform them that your address was used on their site by mistake.

If you've received an email from someone you know but it was sent to another address, then your address is probably listed in the Bcc field. Such messages may be meant for you. Contact the sender some other way and ask them.

In some cases, this may happen if another mailbox is configured to forward messages to your address. If forwarding was set up by someone else, contact the administrator of the server hosting the mailbox that forwards your email and attach a copy of the email along with its properties.
