Don’t make ‘em yawn! Keep your emails exciting and brief. Keep your email subject line short and attention-grabbing. Don’t forget to add a fun, relevant call-to-action button to your email. Let your imagination run wild. A mobile-responsive email can increase clicks by 15%. Always check mobile previews before sending out emails. Sit up straight. Avoid getting marked as spam! Only email people who have agreed to receive emails from you. Test, test, and test again! Make sure your email looks good on all devices before you send it out.
