FAQ

Survey subject line FAQ

Should you incentivize a survey subject line or just ask?

Most brands just ask: only 5% of the survey lines we tracked use discount language, and 4% name an exact percent off. Incentives like PCMag's "Take Our Headphones and Speakers Survey for a Chance to Win Big" lift response volume, but they also attract prize hunters. Plain asks tend to pull feedback from customers who genuinely care, so match the approach to whether you need quantity or candor.

Do question-form subject lines work for survey emails?

Yes, a direct question like "How did we do?" starts the survey in the inbox by prompting a mental answer before the click. Keep the question about the reader's experience rather than your data needs, and reference the specific purchase or visit when you can. It reads as a conversation, not a chore.

How short should a survey subject line be?

Survey lines in our library average 42 characters, short enough to survive mobile truncation. Spend those characters on the ask and the time cost: Target's "Target.com Guest Survey – 2 minutes" does both in under 40. Cut brand taglines and filler; the sender name already carries your identity.

What actually drives survey response rates?

Timing and clarity beat clever copy: send while the purchase or support experience is fresh, state the time commitment up front, and say what the feedback improves. A follow-up helps too, which is why Target prefixes its second send with "Reminder:". Make sure the survey really takes as long as the subject promises, or the next ask gets ignored.
