Survey Email Best Practice

Write emails that actually get opened — and answered.

You built a great survey. Now make sure people actually open the email. The subject line is everything. Keep it under 50 characters, make it personal, and tell them how long it takes. No mystery, no fluff.

What Works

• Short subject line. Under 50 characters. Personal and specific.
• A real sender name. People ignore "noreply@". Use a human.
• One single button. One CTA. No competing links. No distractions.
• Set expectations. "Takes 2 minutes" beats "quick survey" every time. Be specific.
• Tell them why it matters. "Your feedback shapes what we do next" gives purpose.
• Keep it tight. 3–4 lines max before the button. Say less, get more.
• Send fast. Within 24 hours of the interaction. Memory fades, and so do response rates.
• Mobile-friendly. Over half will open on their phone. Design for it.

What Kills Response Rates

• Generic subject lines ("Customer Satisfaction Survey Q2")
• Massive banner images pushing the button below the fold
• "Dear customer" — zero personalization
• No mention of how long it takes
• "Please answer our 12 questions" — never reveal a high question count
• Multiple links competing for attention
