10 Email Marketing hacks to skyrocket your open rates

Email marketing is one of the most powerful ways to connect with your audience, but let’s face it—getting people to open your emails can feel like pulling teeth. Whether you’re a startup founder, a marketer, or a business owner, you know the struggle.

In this post, we’ll go beyond the generic advice and dive into real, actionable strategies you can implement today to improve your email open rates. At the end, we’ll also show you how MailProfile can supercharge your targeting and deliver even better results.


1. Craft Subject Lines That Make People Curious

Your subject line is your email’s first impression—and you don’t get a second chance. It should make readers curious, excited, or intrigued.

Examples That Work:

  • "You won’t believe what we discovered about email marketing..."
  • "3 things you’re doing wrong with your emails (and how to fix them)"
  • "I made this one change and doubled my open rates"

Why It Works:

Curiosity triggers a psychological need to resolve uncertainty. Humans naturally want to know what’s behind a statement or claim.

Pro Tip: Avoid spammy words like “Free,” “Guaranteed,” or “Cash” to improve deliverability.


2. Personalize Beyond First Names

Addressing someone by name is step one, but it’s not enough anymore. Today, personalization means knowing your audience’s interests, behaviors, and preferences.

Example:

Instead of saying:

  • "Hey John, check out our latest blog post."

Try this:

  • "Hey John, since you’re a fan of digital marketing trends, I thought you might love this breakdown of 2024 marketing tactics."

How to Do It:

Use tools like MailProfile to analyze email addresses and uncover insights about user interests and online behavior. Then use those insights to deliver hyper-relevant content.


3. Send Emails at the Right Time

Timing matters more than you think. Studies show the best days to send emails are Tuesday and Thursday mornings. But don’t stop there—test different times based on your audience.

Action Steps:

  • Review your email analytics to see when your audience is most engaged.
  • Run A/B tests with different send times.
  • Automate email delivery based on time zones.


4. Use Preheaders to Complement Subject Lines

Preheaders are the short preview text that appears after your subject line in most inboxes. Use this space wisely to add context or amplify curiosity.

Example:

Subject Line: "Want more conversions?" 

Preheader: "Discover 5 email hacks top marketers use to double sales."


5. Segment Your Audience for Relevance

Generic emails don’t work anymore. Split your audience into groups based on demographics, behavior, or preferences to deliver messages that resonate.

How to Do It Easily:

Use MailProfile to automatically segment your email list based on user interests and platforms they engage with. This saves hours of manual work and improves relevance.


6. Optimize for Mobile Users

Did you know 60% of emails are opened on mobile devices? If your emails don’t look good on mobile, you could be losing half your audience.

Quick Fixes:

  • Use short paragraphs and bullet points.
  • Keep subject lines under 50 characters.
  • Test emails on multiple devices before sending.


7. Build Trust With Social Proof

People are more likely to trust and engage with emails that feature testimonials, reviews, or case studies.

Example:

“Over 10,000 marketers use MailProfile to boost their email targeting. See how they increased open rates by 47%."


8. Create Urgency Without Being Pushy

Limited-time offers and countdown timers can encourage immediate action—but use them sparingly.

Example:

“Only 5 spots left for our webinar—reserve yours now!”


9. Test Everything (Seriously, Everything)

Small tweaks can make a big impact. Test subject lines, sender names, CTAs, and layouts regularly to see what resonates best.

Pro Tip:

Use A/B testing tools built into your email marketing platform to experiment and refine over time.


10. Maintain a Healthy Email List

High bounce rates and spam complaints can tank your deliverability. Regularly clean your list to remove inactive or invalid email addresses.

Action Steps:

  • Use email verification tools to validate addresses.
  • Remove subscribers who haven’t opened an email in 6 months.
  • Send re-engagement campaigns to win back inactive users.
