Considered a form of interruption marketing, interstitials are any page or pop-up that forms a roadblock to users’ path to content, either by displaying over the content or interrupting it. Users have no choice but to interact with the display before they can proceed. Forbes was a classic example of the “before” interstitial (also known as a “prestitial”).
It’s important to note that these systems make your job a whole lot easier through automation. The leads can sign up, be added to the list, start getting emails, even make sales… All while you sleep. With these systems, you can send the same email to thousands of people at the same time, automatically. You could potentially set up a schedule of emails going out for weeks or more at a time. You can even manually send emails if you want to run campaigns or send out messages on the fly.
Give it a try. Every optin list provider gives a set of code to paste into your website. You can paste it anywhere you like. I put it on my contact page and on the end of most posts. They call the code a trip wire because you can scatter the code throughout your website to encourage people to sign in. When using visual editing I usually type 3 *** where I want to insert the code. Then I go to text edit find and remove the *** and replace it with the sign in code.
For effective and actionable results, you should do A/B tests, which test two (or more) different approaches. For example, you could send half of your list one subject line, and an alternate subject line to the other half. You could also A/B test the two approaches with a small subset of your list, then send the winning headline to the rest of the list.
