Manage emails not addressed to you in Yahoo Mail

If there are emails in your inbox that are not addressed to you, there are some things you can do. Once you identify the senders, deal with them depending on who they are.

Identify senders

Before acting, determine who is sending you these emails. This may not be as simple as marking the "From" field. Spammers and malicious programs may try to hide or falsify your identity. Check the full header of the email message.

Consider if you are the desired recipient

If your address is not in the "To" or "CC" fields, you can be a recipient of "BCC" (hidden copy). Senders use the BCC field to hide the addresses of non-BCC recipients, often for privacy reasons.

Yahoo email addresses are unique: emails in your inbox are never for another person with the same address. When users create new Yahoo accounts, their IDs are verified in our worldwide database and rejected if they already exist.

To take action

1. Notify senders: Inform known senders about your erroneous or excessive emails.
2. Filter emails: Automatically send emails from an address or domain to a separate folder.
3. Mark your emails as spam: notify Yahoo that an address is a spammer and automatically send all your incoming emails to the Spam folder.
