11 Best email subject line personalization practices

Here are the 11 cutting-edge ways to personalize email subject lines in 2023.

1. Use the recipient's name

Using the recipient's name in the subject line instantly grabs their attention and makes the email feel more personal. For instance:

  • "John, Unlock 20% Off Your Next Purchase!"

  • "Sarah, Your Exclusive Invitation Inside..."

2. Transaction history

Referencing past interactions or purchases can demonstrate that you remember your recipient's history with your brand. Examples include:

  • "Thanks for Being a Loyal Customer, Mark!"

  • "Recap: Your Recent Consultation with [Your Company]"

Use this as an opportunity to further resell/upsell your products and services.

3. Create a sense of urgency

Incorporate urgency to prompt immediate action. Examples may include:

  • "Last Chance: Limited Stock Left of Your Favorite Products!"

  • "Only 10 Hours Left! Quick, Secure Your Spot At The Webinar!"

4. Ask a question

Create curiosity-driven subject lines that lead to interactive experiences within the email. For example, you may pose a question that piques the recipient's curiosity.

  • "Ready for a Home Makeover, Jane?"

  • "Ever Wondered How to Boost Your Productivity?"

5. Social proof and testimonials

Incorporate social proof by showcasing testimonials or success stories in your subject lines. This builds trust and credibility. Here are the examples to better understand:

  • "See How [Customer] Achieved [Outcome] with [Product]"

  • "Join [Number] Happy Customers Raving About [Experience/Product]"

  • "Cheers to 5 years of Partnership, [Company Name] and [Recipient Name]!"

  • "Don't Forget: Your Event is Just 2 Days Away!"

Marketers can also leverage Mailmodo to embed forms and add widgets within the emails.

8. Dynamic content teasers

Tease the content within your email by showcasing a snippet of the valuable insights or offerings waiting inside. For instance,

  • "Get Ready to Unleash Your Creativity: Our Exclusive Guide Inside!"

  • "We've Got Something Awesome for You, Reena!"

9. Local flavor and culture

Infuse subject lines with local flavor or cultural nuances that resonate with recipients. This level of personalization demonstrates a deep understanding of their lifestyle. Let's take, for example, the following subject lines:

  • "Unveiling [Product Name] Inspired by [Local Landmark/Cuisine]!"

  • "Discover [Product Name] Infused with [Cultural Element]: A Taste of [Region]!"

10. Address pain points directly

Identify your audience's pain points and offer solutions directly in your subject lines. Examples include:

  • "Struggling with [Challenge]? Here's Your [Solution] Roadmap"

  • "Overcome [Pain Point] Today: Actionable Tips Inside"

11. Data-driven predictive personalization

Use data analytics to predict subscriber preferences and customize subject lines accordingly. This not only drives email opens but also enhances the overall user experience.

Furthermore, you can leverage advanced AI algorithms to analyze vast user data and create subject lines tailored to individual preferences.
