How to Optimize Your Email Preheader Text

In email marketing, every element of an email plays a role in determining its success, from the subject line to the call-to-action (CTA) at the end. One often overlooked yet critically important component is the . This brief snippet of text, visible in the inbox next to or below the subject line, can have a significant impact on your open rates and overall email performance.

If used strategically, preheader text can effectively complement your subject line, engage your audience, and increase the chances of your emails being opened. This article explores how to optimize your email preheader text to improve engagement, boost open rates, and enhance the effectiveness of your email marketing campaigns.

What is Preheader Text?

Preheader text is the short snippet of text that appears in an email inbox preview, usually after or below the subject line. It’s the first thing subscribers see when they view their inbox, and in many cases, it helps determine whether they will open the email.

In the most basic sense, preheader text functions as a secondary subject line. Its purpose is to expand on or complement the subject line, offering more context, setting expectations, and enticing recipients to open the email.

For example, consider the following:

  • Subject Line: “Big Savings This Week Only!”
  • Preheader Text: “Up to 50% off select items. Don’t miss out!”

In this case, the preheader text directly supports the subject line by providing additional information, making the email more compelling.

Why is Preheader Text Important?

Optimizing preheader text can improve your email marketing performance in several key ways:

  1. Improves Open Rates: The preheader text is one of the first things recipients see, often alongside the subject line in the inbox preview. A well-crafted preheader text can make your email stand out and encourage the recipient to open it.
  2. Sets Expectations: The preheader text helps clarify what the email is about. It gives subscribers a preview of the content, making them more likely to engage if the subject matter is relevant to their interests.
  3. Increases Mobile Optimization: On mobile devices, where screen space is limited, the subject line and preheader text are often displayed together in a preview. A well-optimized preheader can provide additional context when the subject line is cut off, which is particularly important for mobile users.
  4. Supports Email Consistency: Preheader text allows you to reinforce your brand voice and messaging. When it complements the subject line and aligns with the body of the email, it creates a more cohesive and effective communication strategy.
  5. Increases Click-Through Rates (CTR): When combined with a compelling subject line, the preheader text can drive users to click through and engage with your email content.

Best Practices for Optimizing Email Preheader Text

Now that we’ve established the importance of preheader text, let’s dive into the best practices to ensure you’re using it effectively.

1. Align Preheader Text with the Subject Line

The preheader text should always align with the subject line, reinforcing the message and offering more context. If the subject line is intriguing but vague, the preheader can help clarify the value proposition. Together, they should work as a unified message that entices the recipient to open the email.

For example, if your subject line is promotional, the preheader text can provide specifics about the offer:

  • Subject Line: “50% Off All Apparel – Limited Time!”
  • Preheader Text: “Shop your favorite brands and save big before the sale ends!”

This combination gives the recipient a clear understanding of what they’ll get by opening the email: a limited-time sale on apparel.

2. Keep It Short and Sweet

Preheader text needs to be concise. While there’s no strict rule about the exact length, aim for about 35-90 characters to ensure your message fits well across devices, especially on mobile. On mobile, where space is limited, your preheader text could get cut off if it’s too long.

A short, punchy preheader text is more likely to grab attention, and it fits better with how most users scan their inbox. Be mindful of truncation across various devices and email clients.

3. Avoid Redundancy

Don’t just repeat what’s already in the subject line. The preheader text should add value by providing additional context, details, or a call to action that isn’t explicitly stated in the subject line.

For example:

  • Subject Line: “Shop the Best Gifts of the Season”
  • Preheader Text: “Find something special for everyone on your list!”

In this case, the preheader text adds a personal touch, creating a sense of excitement and urgency without merely repeating the subject line.

4. Create Urgency or Curiosity

Like your subject line, your preheader text should prompt action by appealing to emotions such as urgency, exclusivity, or curiosity. You want the recipient to feel like they might miss out on something important if they don’t open your email right away.

For example:

  • Subject Line: “Exclusive Sale – Today Only!”
  • Preheader Text: “Hurry, these deals won’t last long!”

This creates a sense of urgency, nudging recipients to open the email before the offer expires.

5. Personalize the Preheader Text

Personalization is a powerful tool in email marketing. When you use data about your subscribers—such as their names, past purchases, or browsing history—you can create preheader text that feels more relevant and personalized to each individual.

For instance, if you know the recipient recently browsed shoes on your website, you could use preheader text like:

  • Subject Line: “New Arrivals in Your Favorite Styles!”
  • Preheader Text: “Check out the latest shoes we think you’ll love.”

Personalized preheader text resonates with recipients, making them more likely to open the email.

6. A/B Test Your Preheader Text

Just like with subject lines, you should test different versions of your preheader text to see which performs best. A/B testing allows you to measure how small changes in phrasing, tone, and length can affect open rates and engagement.

For example, try comparing these two variations:

  • Preheader Text A: “Don’t miss out on our biggest sale of the year!”
  • Preheader Text B: “Shop now for exclusive discounts before time runs out!”

By testing these variations, you can determine which one resonates better with your audience, helping you optimize future emails.

7. Avoid Overloading with Too Much Information

While your preheader text should be descriptive, don’t overwhelm your recipients with too much information. The goal is to tease the content of the email, not to give everything away upfront. Keep it focused and succinct.

8. Include a Clear Call to Action (CTA)

Including a CTA in the preheader text can help guide the recipient on what to do next. Phrases like “Shop now,” “Learn more,” or “Get started” create a clear expectation of what’s inside the email, motivating recipients to engage.

For example:

  • Subject Line: “Ready to Save on Your Next Purchase?”
  • Preheader Text: “Click here to unlock your exclusive 20% discount!”

This approach uses the preheader text to tell the recipient exactly what to do next and what they’ll gain by opening the email.

9. Consider the Mobile Experience

Since a significant portion of email opens happens on mobile devices, your preheader text must be mobile-friendly. Keep in mind that on mobile devices, both the subject line and preheader text appear together, and space is limited. Make sure your preheader text doesn’t get cut off, and ensure it complements the subject line without being repetitive.

On a mobile device, you may see a subject line of 40-50 characters and preheader text that’s typically around 90 characters or less. Test your emails on various devices to ensure that both the subject line and preheader text appear as intended.

10. Stay On Brand

Your preheader text should reflect your brand’s tone, voice, and messaging. Whether your brand is casual, professional, or humorous, consistency in your preheader text helps build trust with your subscribers. Keep your language in line with how your brand communicates in other email components.

For example, if you have a friendly and approachable brand voice, you might use a preheader text like:

  • Subject Line: “Say Hello to Our New Collection!”
  • Preheader Text: “We’ve got something special for you. Take a peek!”

This friendly tone matches the subject line and maintains a consistent brand identity.

11. Avoid Spammy Words and Phrases

Be careful not to use language that could trigger spam filters. Words like “free,” “guaranteed,” “no cost,” and “risk-free” are often flagged by email clients, which could cause your email to land in the spam folder rather than the inbox. Always test your emails for spam triggers to maximize deliverability.
