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.
