Why Do Funny Email Subject Lines Work?

Humorous email subject lines slice through the monotony, spark curiosity and tap into the reader’s reward center. Let’s see how they accelerate your email marketing efforts.

• Higher Open Rates: A subject line that makes someone laugh is more likely to be opened, as it stands out from the typical transactional or promotional language.
• Memorability: Humorous content is memorable. A recipient who enjoys a laugh is more likely to remember the email and the brand that sent it.
• Stress Relief: In a busy workday, a light-hearted subject line can be a welcome stress reliever, making the recipient more positively inclined towards the sender.
