Email Subject Line Best Practices

Subject lines directly determine email open rates, making them one of the most critical elements of email marketing. Research shows that 33% of email recipients open emails based on the subject line alone, highlighting its importance in campaign success.

Length significantly impacts subject line effectiveness. Studies indicate that subject lines between 41-50 characters achieve the highest open rates on average. With 46% of all email opens occurring on mobile devices, keeping subject lines under 60 characters ensures they display properly across all devices.

Different approaches work for different goals. Question-based subject lines typically see 10-15% higher open rates for educational content, while urgency-based subject lines perform better for promotions, increasing open rates by up to 22%. Our generator provides a mix of approaches to test with your specific audience.

Personalization boosts performance. Subject lines that include the recipient's name have been shown to increase open rates by 29.3% on average. Similarly, subject lines relevant to the recipient's location, interests, or past behavior perform 50% better than generic alternatives.
