While email is 40 times more effective at acquiring new customers than Facebook or Twitter, crafting a poorly-optimized or “spammy” email will lose customers. In fact, many businesses don't know how to write a truly effective email subject line.
To help optimize your emails, we’ve put together tips to help you write great subject lines that convert.
First Impressions Are Everything
33% of email recipients open an email based on the subject line, so make sure yours are great. Your subject line should always contain two things: importance and relevance. This means balancing style and substance—make your email catchy without sacrificing its quality.
Urgency
If you’ve been in email digital marketing for a while, you’re familiar with the concept of urgency. Urgency tells people they must act "now" to receive a benefit. Urgency makes people anxious that they’ll miss out on a limited time offer, and makes your email seem more important. Creating urgency is a great way to ensure your email is opened.
Great email subject line examples conveying urgency:
- JetBlue: “You’re missing out on points”
- Warby Parker: “Uh-oh, your prescription is expiring”
- Digital Marketer “[Weekend only] Get this now before it’s gone…”
Curiosity
Your subject line is the hook into your email. Hinting at a benefit your audience will receive if they open it piques interest and leaves people wanting more.
Great email subject line examples conveying curiosity:
- Thrillist: “What They Eat in Prison”
- Grubhub: “Last Day to See What This Mystery Email is All About”
- Mary Fernandez: “A Surprise Gift for You!”
Promotional Offers
People love getting things for free. Offering something in your email subject line that conveys your audience will get something for free, or receive value from reading your email, instantly makes your email more popular. People want to feel special. Offer unique promotions and pique your audience's interest.
Great email subject line examples with promotions:
- The Black Tux: "Get priority access."
- Guess: 25% off Your Favorites
- Topshop: Get a Head Start on Summer
Personalization
Personalizing your subject line is about more than just changing the name of each recipient. These days you can access data about your subscribers preferences, occupations, and interests. By leveraging this information you can create content that people want to read on an individual level.
Great email subject line examples with personalization:
- Rent the Runway: “Happy Birthday Mary – Surprise Inside!”
- Guess: “Check out our hand-picked looks”

Relevance
Customers want to receive emails that are specific to them and timely. Sending timely emails can inform your subscribers about what’s to come and register people on different mailing lists.
Additional tips to write effective subject lines:
- Keep it short. Your subject line should be 60 characters (desktop) or 20 (mobile).
- Begin with your most important words and delete and filler words. Ex. “Age-defying beauty tricks”
- Make it easy for your audience to find your email in their inbox later, and include a keyword that they can search for.
- Always highlight the value of opening your email.
- Use emoji’s where appropriate (56 percent of brands using an emoji in their subject line had a higher open rate)
- DON’T USE ALL CAPS – it makes you seem like you are yelling and no one wants to be yelled at. If you need to use caps to get someone to read your subject line, then you need a better subject line.
