This blog post will share some tried-and-true tips to help enhance your subject lines and boost your email engagement.

Best Practices for Email Subject Lines

Grab Attention

Your email subject line is a mini advertisement for your content. To stand out in the inbox, you need to instantly grab your audience's attention. This could be through a catchy piece of copy, including the recipient's name in the subject line, or using pictorial additions like emojis to help separate your business’ subject line from the rest of the inbox.

Convey Relevance

Email subject lines should offer information that is relevant to the recipient and hint at the content they can expect to find if they open your email. Subject lines that speak to the value or relevance of a product are especially effective for emails meant to drive customers to a product.

Create Curiosity

Email subject lines should pique your audience's interest. You want to grab their attention, but you also want to make them curious. The goal is to provide a tantalizing taste that makes them decide whether they want to invest their time in reading further.

Drive Action

Think about the main goal and call to action of your email campaign. What action do you want your audience to take once they've read your email? Make sure your subject line is clear about your business's desired action.

Create a Sense of Urgency or Exclusivity

Creating urgency in your subject line captures your audience's attention and encourages them to open your business’ email immediately. Crafting an exclusive air in your subject line can promote feelings of specialty.

Personalize When Possible

People respond best when they feel communication is personal. Use dynamic fields to auto-populate your subject lines with the recipient's name to grab their attention.

Use a Familiar Sender Name

Your audience is more likely to open emails from a sender name familiar to them. Selecting a regularly occurring sender name to represent your business can help build trust with your audience, increasing their likelihood of opening.

Tips to Create Good Email Subject Lines

Keep It Short and Snappy

With nearly 50% of all emails now opened on mobile devices, shorter subject lines are more effective. Most mobile email clients will only display around four or five words before your subject line is cut off. Therefore, it's important to make your subject line pop in those first few words.

Avoid Spam Words in Your Email Subject Lines

With 333 billion emails sent and received every day around the world, standing out from spam is increasingly difficult. Avoid spammy words or phrases to ensure your emails are not flagged as spam.

• Specific word choice (#1, 100% satisfied, bonus, certified, cheap, join millions, etc.)
• Messages in ALL CAPS
• Emails without an unsubscribe button
• Colorful, hard to read, and different sized fonts

Ask Open-Ended Questions in the Subject Line

Asking a question in your email subject line is a great way to pique your audience's interest and curiosity.

"Hi Tosan, do you want 20% off your next order? "

"How do your results compare to the competition?"

Include a Deadline in the Subject Line

Including a deadline in your subject line creates a sense of urgency that can encourage readers to prioritize your email.

“Don’t open this email… Just kidding, you totally should!”

“Oops, We Found Your Secret Dancing Video!”

“Your Boss Approved Extra Nap Time!”

Say Something Unexpected or Intriguing
