Crafting an email subject line is no small feat—it’s the make-or-break moment for your email campaign. In fact, 47% of people decide whether to open an email based on the subject line alone. Ready to take your subject line game to the next level? Here are 10 proven tips to help you create subject lines that convert.
Your subject line is the first thing your recipient sees. It’s the gateway to your email content and determines whether your email gets opened or ignored. Think of it as your headline—it needs to grab attention and spark curiosity.
A great subject line not only boosts your open rates but sets the tone for the rest of your email campaign.
Attention spans are short, and inboxes are crowded. Aim for subject lines with 6–10 words or fewer than 50 characters. Shorter subject lines ensure your message isn’t cut off on mobile devices or email previews.
Example:
Add a touch of personalization to make your subject lines more relevant. Include the recipient’s name, location, or even their past behavior. Personalized subject lines can increase open rates by up to 22%.
Examples:
Numbers help create specificity and grab attention. Use them to highlight lists, statistics, or offers.
Why it works: Numbers provide clarity and set expectations for the content inside.
Subject lines that emphasize urgency or scarcity motivate action. Tap into your audience’s fear of missing out (FOMO).
Urgency makes the reader feel compelled to act immediately, increasing open rates.
Intrigue your audience by sparking their curiosity. A well-crafted mystery can encourage them to click to learn more.
Tip: Make sure to deliver on the promise of your subject line to maintain trust.
Steer clear of words and symbols that might send your email to the spam folder. Overuse of words like “Free,” “Win,” or excessive punctuation (!!) can harm deliverability.
Instead of: "Win Big with This Free Offer!!!" Try: "Your Exclusive Gift Awaits – Claim Now."
Don’t guess—test! Use tools like A/B testing or subject line graders to see which subject lines perform best.
For instance, test:
Analyze the results and refine your approach over time.
Emojis can help your subject line pop in a crowded inbox. Use them sparingly and ensure they align with your brand’s tone.
But remember: Overusing emojis can make your email look unprofessional.
A misleading subject line might get clicks, but it harms trust. Your subject line should match the content of your email.
For example: If your subject line says "Exclusive Discount – Today Only!" ensure there’s a discount waiting inside.
Your email subject line is more than just a sentence—it’s your chance to make a first impression. Whether you’re crafting a listicle, creating urgency, or personalizing the message, the key is to always think about what will resonate with your audience.
