12 Practices That Drive Results

Follow these to get better opens, more clicks, and a healthier sender reputation.

✉️
Subject Lines That Get Opened
Avg lift: +25% open rate
  • Keep subject lines under 50 characters — most mobile clients cut off longer ones
  • Use the recipient's first name when possible — personalization boosts opens by ~20%
  • Create curiosity without being clickbait — tease the content without giving it all away
  • Avoid spam trigger words: FREE, GUARANTEED, ACT NOW, LIMITED TIME
  • Test emoji sparingly — they can increase opens but only when used appropriately
⏰
Send at the Right Time
Avg lift: +15% open rate
  • Tuesday, Wednesday, Thursday are consistently the best days to send
  • Best times: 10am–11am and 2pm–3pm in the recipient's local timezone
  • Avoid Monday mornings (inbox overload) and Friday afternoons (low engagement)
  • Use BouncePro's send-time optimization to automatically send at each subscriber's best time
🎯
Segment Your Audience
Avg lift: +40% click rate
  • Don't send the same email to everyone — segment by behavior, location, or purchase history
  • Create segments for new subscribers, active customers, and lapsed contacts
  • Tailor content to each segment's stage in the customer journey
  • Segmented campaigns generate up to 760% more revenue than blanket sends
📱
Design for Mobile First
60%+ of emails opened on mobile
  • Use a single-column layout — easier to read on small screens
  • Minimum 14px body text, 22px+ for headings
  • Make CTA buttons at least 44px tall — easy to tap with a thumb
  • Keep important content in the top 150px — visible before scrolling
  • Always preview your email on mobile before sending
🔁
Use Automation Wisely
Automated emails get 70% more opens
  • Set up a welcome sequence immediately — new subscribers are most engaged within 24 hours
  • Use behavior triggers — emails sent based on actions convert 3x better
  • Limit automation frequency — don't send more than 1 automated email per day per subscriber
  • Include an easy unsubscribe option in every automated email
🧪
A/B Test Everything
Ongoing improvement, every send
  • Test one variable at a time — subject line, send time, CTA, or layout
  • Use a minimum 1,000-contact sample per variant for statistically significant results
  • Run tests for at least 4 hours before declaring a winner
  • Document your test results and build on them over time
Pro tip: The single biggest lever in email marketing is list quality — not design, not subject lines, not send time. A small, highly engaged list will always outperform a large, cold one. Focus on growing slowly and organically.
