How do you delete a contact from Yahoo mail?
Log into your Yahoo mail and select Contacts from the column on the left-hand side.

When your contacts appear, put a check next to the contacts or contacts you wish to delete.

Then select the trashcan icon to the right of your contact.

You’ll be asked to confirm the request to delete. Now your contact will be gone.

The format for my account is the same as the first step but there is no small box next to the name.
