A mobile-responsive email can increase clicks by 15%. Always check mobile previews before sending out emails. Get creative with emojis in email subject lines to increase open rates! Try different email subject line styles to find what gets the most opens. Don’t forget to add a fun, relevant call-to-action button to your email. Is anyone even reading this? Keep your email subject line short and attention-grabbing. Don’t forget to add a short preview description to encourage people to click on your email. Sit up straight.
