Not just a pretty interface Don’t forget to add a short preview description to encourage people to click on your email. Sit up straight. Try different email subject line styles to find what gets the most opens. Want the loading time to be longer so we can spend more time together :) Keep your email subject line short and attention-grabbing. Don’t forget to add a fun, relevant call-to-action button to your email. Keep an eye on your email open rate to analyze and improve performance!
