Quit Mail. Back up all data.


Triple-click the line of text below to select it, then copy to the Clipboard:

/Library/Mail/Bundles

In the Finder, select Go Go to Folder from the menu bar. Paste into the box that opens, then press return.


A folder may open. If it does, move the following item in that folder to the Trash:


UnsubMailPluginMailAppOSX.mailbundle


You may be prompted for your password when you do this.


Launch Mail.
