Frequently Asked Questions
What email subject lines get the highest open rates?
Personalized subjects (with first name), curiosity-gap subjects ("You made a mistake..."), and urgency subjects ("Last chance: offer ends tonight") consistently achieve the highest open rates. Keep subjects under 50 characters for mobile.
Should I use emojis in email subject lines?
Emojis can increase open rates by 10-15% when used sparingly and relevantly (1 emoji maximum). They stand out in crowded inboxes. Avoid overuse or spam-triggering emojis.
