Arguably, this form of marketing is quite popular as well. Users love it when prizes are on offer, and they like it, even more, when they have to win them! Termed by many as digital sweepstakes, it enriches their competitive spirit and helps you to generate the right attention. Just get them to write some slogan, taglines, participate in quizzes, post pictures, or share your content—and in turn, offer them something.
Look into the statistics of your blog, what are the articles which are driving the biggest amount of traffic? It might be worthwhile to convert those blog post into white papers and setting up a landing page for them. Setting up a landing page takes to much time? Just offer for people to download the post in PDF format in exchange for their email address.
When it comes to designing an email for a specific offer, the main component to keep in mind is the offer itself. You want the copy to be brief but descriptive enough to convey the offer's value. In addition, make sure your email's call-to-action (CTA) link is large, clear, and uses actionable language. You can also include a large CTA image/button underneath to make the action you want email readers to take crystal clear.
