Should Digests Emails (html version) contain a summary with anchor links?
I get digest emails from Yahoo Groups and they contain a summary of messages at the top. Clicking the link in a summary takes me to an anchor within the email, so I can skip right to the message I want to read. Other digest emails, like the Burning Man newsletter, include a summary at the top, but you still have to scroll on your own to find the part you're looking for.
I hear that anchor links in email is a bad practice, but I rather like the experience. What are the best practices for designing email digests?
