Visual Strategy
Using 1-2 emojis in subject lines can boost open rates by 15-20% for marketing emails.
Adding emojis to subject lines can boost open rates, but selecting the wrong one or overcrowding your text can trigger spam filters or look unprofessional. Furthermore, emojis render differently on mobile vs desktop, often causing layout inconsistencies.
The Emoji Subject Line Previewer lets you visualize your subject lines before hitting send. Test various emojis, evaluate their visual impact in context, and simulate how they will appear in your recipient's actual inbox environment.
