Practical Ways to Boost Your Email Open Rates in 2025

(With Fresh Data, Simple Tips, and Real World Examples)

Email marketing still works–and it works well. However, in 2025, your audience is busier, inboxes are more crowded and attention spans are shorter than ever. So if your open rates aren’t where you want them to be, it might be time for a tune-up. 

Let’s start with a reality check, shall we?

• The average email open rate in 2025 across all industries is 26.64% (Omnisend).
• Over 70% of readers open emails on mobile; but… 
• 49.2% of people say they only open a few brand emails a day (Mailjet).

So, how do you make sure your email doesn’t get swiped past?

Here are 12 proven ways to boost your email open rate.

1. Nail the Subject Line

Usually, you have 3-4 seconds to make an impression. A great subject line is short, personal, clear, and sparks interest. 

Subject line quick tips:

• Keep it under 50 characters
• Add numbers (sparingly)
• Use light emojis for flair (if possible)
• Personalize with a name or reference
• Add urgency (“Last Chance to Register”)
• Ask a question (“Still Thinking About That Villa?”)

Good example: “24-Hour Flash Deal: New Properties Just Dropped”

Not-so-good: “Big News Inside You Won’t Believe”

2. Write a Killer Preheader Text

The subject line pulls readers in, while the preheader seals the deal.

It’s that little snippet of text that shows up next to or under your subject line, and yes, it matters a great deal.

Useful tips:

• Keep it short (30-90 characters)
• Make it continue your subject line, not repeat it
• Add a benefit or teaser

Example of the perfect combo:

Subject: “Unlock Your Free Consultation Today”

Preheader: “Let’s talk about your investment goals–book now.”

3. Use a Recognizable Sender Name

If the sender name is confusing or inconsistent, subscribers will hesitate.

Best practices:

• Use your brand name, or a combo like “Fatima from GreenKey Real Estate”
• Stay consistent across campaigns

Bonus: Enabling a BIMI logo (once your email is authenticated) means your brand logo can show up next to the email. It builds instant trust.

4. Personalize Beyond First Names

Sure, “Hi [Name]” still helps, but it’s no longer enough. 

Modern personalization includes:

• Product or service recommendations based on user behavior
• Localized content (e.g., events in the subscriber’s area)
• Dynamic offers or reminders based on past actions

Example:

If a subscriber browsed beachfront apartments, you can send:

Subject: “Still dreaming of Palm views? Here’s what’s available this week”

Body: Curated listings + time-sensitive offer.

5. Segment, Segment, Segment, and Did We Mention Segment?

Sending one email to your entire list is the digital equivalent of shouting into a crowd. 

Smart segmentation lets your tailor messaging based on:

• Demographics 
• Location
• Past purchases or interactions
• Engagement level 
• Buyer journey stage 

According to Litmus, 90% of marketers saw improved performance after segmenting their audience.

6. Time It Right

Your send time matters more than you think. While it varies by audience, Omnisend found that:

• 8 PM has the highest open rates
• Followed by 2 PM and 11 AM
• Avoid 4 AM (unless you’re emailing owls!)

But then again, test what works for your audience, and once you know it, stay consistent, because that’s the key!

7. Optimize for Mobile

With over 64% of emails opened on mobile according to ZeroBounce, your design can’t afford to fumble on small screens. 

Mobile friendly checklist:

• Use a responsive, single-column layout
• Keep the subject lines and purview text short
• Increase font sizes (14-16px min)
• Use large, tappable buttons
• Compress images for fast loading
• Always test on mobile before sending

8. Keep Your Email List Clean

A bloated, outdated list drags everything down. 

Check out these best practices:

• Use double opt-in
• Remove bounced and inactive emails
• Run re-engagement campaigns
• Make unsubscribing easy (yes, really)
• Monitor bounce rates and update data regularly

Remainder: 28% of an email list degrades every year according to ZeroBounce. 

9. Avoid the Spam Folder

Even a well-crafted email won’t perform if it gets flagged as spam.

Avoid:

• All caps or too many exclamation points (!!!)
• Words like “Free!!”, “Act now!”, or “Buy instantly”
• Excessive symbols
• No unsubscribe link
• Overloaded images with no text

Instead, try:

• Using a balance of clean text and visuals
• Adding authentication (SPE, DKIM, DMARC)
• Making your email readable, not robotic 

10. Use Action-Oriented CTAs

Don’t bury the CTA or make people guess what to do next. 

Examples of good CTAs:

• “Book Your Free Consultation”
• “Get the List of Hot Properties”
• “View Available Units Now”

Position CTAs high in the email and repeat (sparingly) toward the end. Test colors, wording, and placement. 

11. Automate With Purpose

Automated emails may only make up 2% of your volume, but they drive 37% of sales (Omnisend).

Examples:

• Welcome series
• Abandoned cart reminders
• Re-engagement nudges
• Upsell/cross-sell recommendations

Set them up once, monitor results, and let them work in the background. 

12. Test Everything!

Split-test subject lines, CTA placement, button colors, even emoji use. 

Track:

• Open rates
• click -through rates
• Unsubscribes
• Conversion rates

Every campaign is a chance to get sharper.

Final Thoughts: It’s a Game of Relevance, Not Volume

If you’re still blasting one-size-fits-all emails at random times, your results will match the effort. However, with smarter subject lines, clean lists, mobile-ready content, and timely sending, you’ll boost open rates and create emails people actually want to open.
