Hello @DawnMarieR41 ,
You can utilize Read More blocks for webpage links, or link to longer documents (e.g. PDFs or DOCs) uploaded to your library to help save length in your newsletters. Since the vast majority of email programs don't support (or actively spam out) anchor links, that table-of-contents type functionality is no longer available in our email builder.
