Email Marketing
Email Subject Line
An email subject line is the first line of text recipients see in their inbox and is the primary factor determining whether they open the email. Compelling subject lines dramatically impact open rates and campaign success.
Examples
A subject line test reveals that "Your exclusive 40% discount expires tonight" outperforms "Special offer inside" by 65% in open rate.
Best Practices
Keep subject lines under 50 characters, create urgency or curiosity, personalize when possible, and always A/B test variations.
