How to Increase Email Open Rates [7 Easy Ways]

Is your email marketing strategy falling flat? Here’s the hard truth: Even the most beautifully designed email campaign is worthless if your subscribers don’t open your emails.

The average email open rate across industries sits around 39.64%, according to recent email marketing statistics. While that’s a decent benchmark, your goal should be to outperform it. Why? Because a higher open rate directly leads to a better email click-through rate, increased conversion, and more revenue. 

If you’re tired of sending bulk emails to people who never open them, this guide is for you. Below, you’ll learn how to increase email open rates and overall engagement with your email campaigns.

Why Email Open Rates Matter in 2025

Your email open rate reflects the percentage of email recipients who open an email. 

It’s a key metric that gives insight into how effective your email content, subject lines, send times, and sender reputation are. 

To calculate your email open rate, divide the number of emails opened or read by the number of recipients, then multiply by 100.

Assuming you sent 100 emails and 10 bounced, the number of recipients becomes 90. If only 50 out of the 90 recipients opened the email, your open rate will become: 

(50/90) x 100 = 55.56%

A low open rate signals that your audience is disengaged or your emails are ending up in spam folders. When fewer people open your email, your click-through and conversion rates also suffer. In today’s competitive market, learning how to increase email open rates is essential to the success of your email marketing campaign.

What is a Good Email Open Rate in 2025?

Email open rates can vary, depending on the type of email, region, and industry. Recent email marketing benchmarks show that marketing emails in the religion niche had the highest open rate (59.70%), while travel and transportation had the least (22.57%).

Here are some updated email open rates by industry:

Proven Tips to Increase Email Open Rates

Now that we’ve seen the average open rate for different industries, let’s get into the actionable stuff. Below are proven tips to improve email open rates and boost your overall email marketing efforts.

1. Write Subject Lines That Spark Curiosity and Clarity

The subject line is the gatekeeper to your email. If it fails to capture attention or clearly communicate value, it doesn’t matter how compelling the content inside is; recipients won’t open your message. 

In 2025, email users are more selective than ever, scanning dozens of messages daily and choosing which ones are worth their time in mere seconds. That’s why it’s critical to balance curiosity and clarity in your subject lines. 

Avoid misleading language or spammy all-caps words; instead, use specific, relevant phrasing that tells the reader what they’ll gain by opening. Keep your email subject line concise, ideally under 50 characters, so it’s visible on mobile devices.

For example, a subject like “Tonight: Emergency Session!” clearly states the offer and adds urgency without being pushy.

2. Personalize Every Email Beyond Just the First Name

Email personalization has gone beyond including someone’s first name in a greeting. Today’s most effective email campaigns use behavioral and demographic data to craft tailored experiences for each recipient. 

Your email can feel personal when you recommend products based on browsing history, send content aligned with the subscriber’s interests, or reference their location or purchase history. In fact, studies show that personalized emails increase open rates by as much as 44.30%, and the impact on click-through rates and conversions is even greater.

Implementing true personalization requires robust data collection. Start by organizing subscribers based on how they interact with your site, what content they engage with, and what actions they’ve taken in past emails. With this information, you can craft emails that speak directly to their needs and goals. 

Email service providers, like AWeber and GetResponse, may include dynamic content tools that allow you to easily switch out images, text, and offers depending on the recipient’s profile. The more relevant your message, the more likely your email is to be opened and read. Here’s how Netflix personalizes its emails:

3. Segment Your Email List for Relevance and Engagement

Sending the same message to your entire email list is a guaranteed way to get overlooked. People expect content that feels like it was made for them, and that’s exactly what email segmentation delivers. You can send targeted emails by dividing your list into groups based on characteristics like age, purchase behavior, location, engagement level, or even sign-up source.

Email recipients are much more likely to open your emails when they see content that’s directly relevant to them. It helps avoid email fatigue and unsubscribes by ensuring that people aren’t receiving irrelevant promotions or repeated messages. For example, a first-time visitor might receive an educational email sequence, while a repeat buyer could get a loyalty discount or VIP offer.

4. Choose the Right Send Time and Frequency

Timing plays a massive role in whether your email gets opened or ignored. If your message lands in someone’s inbox while they’re busy, sleeping, or offline, it may be buried by the time they check their emails again. To increase your email open rate,  identify when your audience is most likely to check and engage with their inbox. 

General studies suggest that the best time to send emails is weekdays, particularly Tuesday and Thursday mornings. However, the ideal time for your list will depend on your specific audience. Use A/B testing and the analytics tools provided by your email platform to track when your emails perform best.

Alongside timing, email frequency is also key to engagement. If you send too many emails, you risk annoying your subscribers and driving them to unsubscribe. But sending too few may cause them to forget about your brand entirely. The best approach is to establish a consistency that aligns with your subscribers’ expectations and your content schedule. 

Always provide an option for recipients to manage their email preferences, such as choosing how often they hear from you. 

5. Maintain a Clean and Healthy Email List

An often-overlooked strategy on how to boost your email open rates is practicing regular email list hygiene. Over time, your email subscriber lists can become cluttered with inactive, invalid, or outdated email addresses. These dead-weight contacts increase your bounce rate, which can damage your sender reputation and impact your deliverability across all emails. 

You ensure that your messages are reaching real people who are interested in hearing from you by routinely removing unengaged users and correcting typos in email addresses. You should also confirm new subscribers with double opt-ins. This also means letting go of subscribers who haven’t interacted with your emails in months. 

You can first attempt a re-engagement campaign to reignite interest, perhaps offering a discount or asking if they’d like to stay on your list. If they still don’t engage, it’s better to remove them than risk hurting your metrics. 

Email platforms often penalize marketers with low engagement, so trimming your list can help increase email open rate. A smaller, more active list will always outperform a larger, disengaged one. Remember: quality is more important than quantity when it comes to your subscriber base.

6. Make Your Emails Mobile-Friendly and Accessible

About 81% of people prefer to open emails on their smartphones, making mobile optimization essential in email marketing. 

If your emails aren’t designed to display properly on mobile devices, you risk frustrating users who might delete them without a second thought. It’s important to use responsive design to ensure images, text, and buttons adjust to different screen sizes. Keep your layouts simple, your fonts legible, and your calls to action easy to tap. 

Accessibility is also important, so make sure your email is easy to navigate for all users. This includes those who rely on screen readers or have vision impairments. Use clear contrast between text and background, add alt text to images, and avoid relying solely on images to convey key information. 

7. A/B Test Regularly to Refine What Works

If you want to consistently improve your email open rates, regular A/B testing should be a core part of your email marketing strategy. Rather than guessing what your audience prefers, A/B testing allows you to compare two variations of a single element. These can be the subject line, sender name, or send time to see which version performs better. 

Even small changes can lead to meaningful gains in your open rate. For example, tweaking a subject line from “Our Monthly Newsletter” to “This Month’s Exclusive Deal Inside” can increase the number of people who open your email. Over time, these insights help you build more productive campaigns.

Most email service providers offer built-in A/B testing tools that automate the process and report on performance. Use those tools to test different copy styles, emojis in subject lines, or even calls to action in the preview text. As you gather more results, you’ll uncover trends unique to your audience, like which days deliver the highest open rates or what tone resonates best.
