The MarketingSherpa 2013 Email Marketing Benchmark Report, clearly shows the popular fields included in the online registration pages. While name and email address takes the first two spots, telephone number only comes in the the fifth spot.
So, what information will you ask for new subscribers? Will you create a long registration page or an easier form to fill (minimal fields).
In many report on user behavior on websites, it’s found that most users resent long registration pages. Often, long registration page is directly linked to high bounce rates. So, it’s recommended to have a lean sign-up page for higher registration.
