How to Write an Email Subject Line That Will Boost Open Rates

Every day, our email inboxes are flooded with newsletters, special offers, event invites, and other similar material. Most of us only open the emails that are relevant to us and trash the rest.

It’s critical to understand how to make your email stand out in a sea of overbearing inboxes. Let’s take a look at the necessary ingredients for crafting an appealing email subject line in order to improve open rates.


1. Make it personal

You’ve built your email list into something more than a database of addresses. It’s a list of people who have opted to share their email addresses with you because they are interested in what you have to offer. Your email subscribers, like you and I, have a variety of interests, professions, ages, and more. Segmenting your email list is the first step toward generating personalised subject lines that catch your recipients’ attention.

It’s a good idea to get to know your customers. Sending an email with a personalised subject line increases the chance of your email being opened by 26%. You may personalise subject lines by suggesting products to your readers based on their previous purchases, request information from them, or even utilise their names from time to time. Here are some examples of how certain companies add personal touches to connect with their email subscribers:

  • “We’re sure you’ll enjoy it!” – Rocketbook
  • “Thank you, Katelyn, for your valuable contribution.” – LinkedIn
  • “Are you ready to boost your productivity levels?” – Fossil


2. Create a sense of urgency

You’re more likely to pique your readers’ attention and motivate them to open your email when you request immediate action in the subject line. Instead of implying scarcity or a time limit, claim offers that urge recipients to take action immediately rather than later. People are typically hesitant to believe they have missed a chance, therefore let your users know that you have something remarkable in store for them if they don’t act quickly.

Urgency may be a useful strategy, but if it’s overused, your audience will notice. If you use urgency too frequently, your recipients will become weary of your emails and lose interest in them. To avoid losing subscribers to email boredom, utilize urgency wisely and how often you employ this approach. You can easily create urgency as these brands do in the examples below.

  • “Trust us, you won’t want to miss this.” – Girlfriend Collective
  • “Don’t miss out on these 3 features” – Grammarly
  • “Shop these new arrivals now” – Madewell


3. Give an offer

It’s no secret that everyone likes a great bargain. If you’re sending an email with a deal, make sure to state so in your subject line! Because readers will see the immediate benefit of opening your email, an offer will improve your open rates and create quicker responses. The use of offers has the advantage of boosting open rates and subject lines may improve them.

Offering discounts or special offers are an excellent approach to reconnect with your followers. However, don’t make promises in your subject line that you can’t keep. If the bulk of your email doesn’t contain a deal or actionable steps to obtaining it, users will lose faith in your company. These situations may provide inspiration for using an offer in the next subject line of your emails.

  • “Unlock 20% Off” – Jimmy John’s
  • “Up to 70% Off Clearance!” – Express
  • “Don’t forget it all ships F-R-E-E” – Loft
4. Spark curiosity

Make your subject line a cliffhanger. When you leave your audience wanting to know more, they will be inclined to click and learn what you have to say. You may entice your audience to read your email by posing an open-ended question, providing exclusive knowledge, or creating a sense of suspense. Your readers’ natural thirst for knowledge will make your email hard to put down.

The subject line is one of the most important aspects of your email marketing campaign. However, if it’s too mysterious or irrelevant to your brand, it might seem like clickbait. To create interest, you don’t need to use ridiculous subject lines. The examples below illustrate the topics without going into too much detail, in keeping with what the businesses provide.

  • “The biggest drop is tomorrow” ­– Adidas
  • “You Won’t Believe Your Eyes” ­– Fossil
  • “5 Tips to Make Online Ordering Easier” ­­– GoDaddy


5. Be timely and relevant

Your email subscribers provided you with their emails for a reason. It’s critical to give your readers timely information that is of interest to them. Sending hundreds of bulk emails to hundreds of people who have bought from you will undoubtedly result in hundreds of junk folders since what you’re offering isn’t relevant to them. Using popular subjects or recent news in your subject lines may help you demonstrate how your brand fits into your readers’ lives. By becoming a useful resource for your audience, your brand will gain credibility. Provide timely and relevant content to intrigue your audience with subject lines like these:

  • “The Best Cold Weather Moisturizer” ­– Healthyish
  • “How to Bake Better Bread” – Bon Appétit
  • “Reminder: Election Day is Tomorrow, Nov 3, 2020” –


When utilised correctly, email marketing may be a significant help to your business. The first step in attracting people to interact with your email ads begins with attention-grabbing subject lines. There are several methods to play with in order to create a subject line that will stand out — keep it focused on the user and true to your brand.
