This SEGA email has a solid foundation. The subject line grabs attention with a big discount, and the preheader effectively highlights a key game. The playful spring design adds charm, but the overall energy feels a bit flat. To enhance engagement, consider adding more excitement in the copy, maybe a fun call-to-action that sparks curiosity. Also, showcasing more visuals or game highlights could draw in the reader's interest. It’s good, but it could definitely shine brighter!
