From "The Email Design Best Practices You Need to Know [3]"

Like anything else in higher education, finding the best email design for your school, college, or program is an ongoing process. You’ll likely need to make adjustments over time to keep your constituents happy and interested.

Analytics data can provide insights about the effectiveness of your email designs. If you find engagement is consistently higher on emails that use just one or two photos, or if you see the highest open rates when you use a certain format for subject lines, take those metrics as signs you’re doing something right. Make sure you constantly review your results to find the email design best practices that work for your brand.
