When a new user registers (or subscribe to your mailing list), don't expect they already grabbed all the value your product can provide to them. Educate them one email at a time with an educative drip campaign and increase your activation in a significative way.
New visitors can either register by themselves or leave your product forever. Your mission is to always have a way to get back to them with a more attracting message. Asking for their email address as soon as they arrive on your website can sometimes be a winning strategy.
A certain percentage of your visitors like what you are doing but they leave and never come back. In order to reach them later, this experiment will teach you how you can install an exit-intent popup and ask for their email address.
Look at what your users are doing on your site as if you were standing behind their shoulders. Get a better understanding of where your visitors are dropping off, test new things and end up improving your conversion rate.
