Previously, when your subscribers wanted to update their subscription preferences (like changing their interest groups or their preferred email format) the only way to do that was by clicking a link in one of your email campaigns. We’ve made things much simpler, and now your subscribers can update their preferences from your subscribe form location just by entering their email address.
If they’re already on the list, we’ll send them an email with a link to update their subscription preferences. Clicking the "update your preferences" link in the email will then take the subscriber to a web-based version of your signup form with their current values pre-filled. The subscriber can then make and submit their changes.
This should be especially helpful for those of you who rely heavily on interest groups for list segmentation.
