I increased my open rates by 17% with these 5 subject line tests: Your subject line is the first impression your email makes. It determines whether your audience opens the email or skips it entirely. Here are 5 subject line tests I ran that actually moved the needle (and why they work): 1. Add Personalization: Instead of: “Improve Your Email Marketing Results” I tested: “Chase, These Email Tips Could Boost Your Revenue” Why this works: Seeing their name feels personal and grabs attention in a crowded inbox. Personalization also shows you’ve tailored the content specifically for them. --- 2. Tap Into Curiosity: Instead of: “Email Marketing Strategies for Your Business” I tested: “You’re Leaving Money on the Table with Email” Why this works: Curiosity compels people to open. But the key is delivering on the promise—your content has to match the intrigue, or you’ll lose trust. --- 3. Create Urgency: Instead of: “How to Improve Your Email Campaigns” I tested: “Last Chance to Fix This Email Mistake” Why this works: FOMO (fear of missing out) gets people to take immediate action, especially when there’s a sense of a ticking clock. --- 4. Go Shorter: Instead of: “Here’s Everything You Need to Know About Email Marketing” I tested: “Better Emails, Today” Why this works: Short, punchy subject lines cut through the noise, especially on mobile where 50%+ of emails are opened. --- 5. Use Numbers or Specificity: Instead of: “Email Tips for Business Owners” I tested: “3 Subject Lines That Boosted Open Rates by 17%” Why this works: Numbers and specificity make your email feel actionable and credible. People know exactly what they’re getting. --- The Big Lesson: Your subject line is your email’s best salesperson. Start testing small variations today—personalization, curiosity, urgency, or brevity. Even a 1% improvement across a large list can make a massive impact. What’s the best subject line you’ve tested?

💡 Your objective with cold email: open, read, reply Part 1: Using “boring subject lines” to drive 40%+ open rates The overwhelming majority of reps make this mistake with their subject lines: ⛔️ Me-centric ✅ You-centric They talk all about their solution, making it easy for prospects to delete the email without even opening it. 🎯 Here’s the key strategy: Match internal communication style - Be familiar - Talk about their world, not your solution or how you help - Keep it short (Salesloft’s data supports subject lines with <5 words) Here are five subject line frameworks with examples of good vs. bad: === 1/ Point out specific problems This tactic works great if you can find specific problems on their website. The key: talk about the problem, not how you can help. ✅ Canada Goose chatbot ⛔️ AI-powered enterprise CX ✅ negative review from Pham T. ⛔️ We can get you more 5-star reviews === 2/ Industry trends or problems This tactic works great if there’s an industry trend or challenge every prospect is thinking about. The key: talk about the trend, not how you can help. ✅ Engage platform R&D credit ⛔️ Pay Less Taxes ✅ Welders ⛔️ Automate welding at ABC COMPANY === 3/ Company initiatives This tactic works great if they’re a publicly traded company or have an investor’s page (pro tip: use Seeking Alpha to find these). The key: talk about the initiative, not how you can help. ✅ 28% growth in Q3 ⛔️ Grow Your Revenue ✅ Interconnection cost reduction ⛔️ Reduce Call Center Costs === 4/ LinkedIn quote This tactic works great if the prospect posts LinkedIn content or has a detailed experience section. The key: talk about them, not how you can help. ✅ Salesloft IPO ⛔️ Finance analytics software ✅ Officer or captain? ⛔️ Reduce project waste === 5/ People on their team This tactic works great if you can find specific people on the prospect’s team who are likely experiencing the problem you help with. The key: talk about their team, not how you can help. ✅ Barry Parker and Katie Grouper ⛔️ HR Hiring Solution === Which subject line formula do you like the best? 👇 Let me know in the comments below #Sales #Prospecting #Outbound
