What makes an email survey subject line effective?

Effective survey subject lines are personal, create curiosity, and stay under 6 words. They should include clear value and trigger emotional responses through personalization, questions, or psychological triggers like authority recognition.

How long should my survey email subject lines be?

Keep them under 30 characters for mobile optimization, ideally 6 words or fewer. Mobile devices only show 25-30 characters before truncation, so front-load important information.

Should I personalize survey subject lines with names?

Yes—personalized subject lines get 26% higher open rates. Go beyond names by using purchase history, location, or behavioral triggers like 'Following your recent purchase...' for deeper connection.

What are the most common survey subject line mistakes to avoid?

Avoid spam words ('Free,' 'Winner'), writing over 50 characters, using ALL CAPS or multiple exclamation marks, and generic phrases like 'Please take our survey.'

How do I A/B test my survey subject lines effectively?

Test with 1,000+ recipients per variation, run for 24-48 hours, aim for 95% confidence. Test one element at a time: length, personalization, tone, or question vs. statement format.
