Our engineers are working on incorporating Contacts into the new format. We appreciate your patience while we work on this.
In the meantime, you can access contacts by clicking on the icon on the upper right side (small icon made up of a rectangle with three small stacked squares). This will open Contacts in a new tab of your browser in the Classic Mail look. You can also access your contacts via https://contacts.yahoo.com.
