One of the main issues I've had (and read about) related to having an effective and engaged email marketing strategy is the ability of the email to be seen by the reader. Emails can often end up in spam folders or promo tabs (gmail). To combat this, I've read that a reader responding to your email will ensure that future emails go to their primary inbox. So, I was thinking it might be a cool idea if you had a basic survey tool built into author.email. Nothing fancy required. But it would allow us to ask a survey question to keep the reader engaged and allow them to receive and see future emails.
