Thank you for reaching out to the Constant Contact Community. I hope you're having a great weekend.
That's a great question. At this time anchor links aren't available in the Third Generation Editor. There is limited support for anchors in email clients, almost every mobile email client doesn't have support for it, and almost half of the most commonly used email clients are mobile. With this in mind, support for anchors is highly inconsistent. However, this editor does have a great Read More Action Block that can allow easier navigation within emails. If you have further questions, please feel free to reach out here.
Thank you for choosing Constant Contact. Have a great day!
