We love to share examples of email done right. This referral announcement from business intelligence platform, Cyfe, is a perfect example of how sometimes, less is more. What Works: Cyfe relies on simple plain text email messages to communicate key information to their user base. In this case, they are announcing a new customer referral program that will help them acquire new users while rewarding their most valued customers. These three simple lines communicate the benefit and provide a clear call to action that can be easily read in any email reader or on any device. We also like that they use their third line to remind users of their value proposition. What Could Be Improved: We really like this email, but we’d love to see the Cyfe logo so they can extend their branding opportunities. The Verdict: Cyfe demonstrates the simple power of three key sentences. Additionally, they provide an unsubscribe link despite transactional email’s exemption from the CAN-SPAM Act. Way to raise the bar.
