Did you know that the return on investment in email marketing can reach an impressive 3800%? But here’s the problem: this potential only becomes a reality when your emails are opened by your subscribers.
The open rate tells you exactly what percentage of your emails are reaching your audience’s eyes. Although the general average is around 20%, some sectors such as the religious sector can shoot this figure up to 59.70%. In fact, nearly 80% of marketers have seen an increase in engagement over the past 12 months.
This data reveals something fundamental: if your emails are not opened, your best content becomes invisible. Click-through rates, which typically range from 2% to 4%, depend entirely on how many people open your messages first.
In this article, you’ll learn exactly how to increase your open rate using proven techniques. You’ll discover everything from subject line optimization to how to effectively segment your audience. You’ll also see why personalized emails can significantly increase your opens and how event-triggered emails reach up to 46.53% open rate.
Do you want to get more people to open your emails and maximize the impact of your campaigns? We show you how to do it step by step.
Key points to increase the open rate
Mastering the open rate in email marketing is essential to maximize the return on investment of your campaigns. Here are the most effective strategies to get more people to open your emails:
• Personalize subjects and segment your audience: Segmented campaigns achieve 14% more opens, while 61% of users value seeing their name in the subject line.
• Keep your list clean and use double opt-in: Databases degrade 22.71% annually; Double opt-in guarantees truly interested subscribers. You can also use email checker services to validate email addresses.
• Optimize for mobile and A/B test: 70% of emails are opened from smartphones; A/B testing allows you to identify what works best.
• Create relevant content and avoid spam: 80.8% of consumers value content tailored to their interests; Maintain a good sender reputation to improve deliverability.
• Take advantage of specialized tools: Platforms like Mailchimp, MailerLite, or GetResponse offer detailed analytics and automation to optimize your campaigns.
Remember that a good open rate ranges between 30-40%, but it varies depending on the sector. The key is consistency, constant experimentation, and regular monitoring of metrics to adjust your strategy based on the results obtained.
What is open rate and why it matters
Open rate is the metric that tells you exactly what percentage of recipients opened your email. This figure goes beyond simple numbers: it reflects the initial interest generated by your campaign and predicts the success of your entire strategy.
How the open rate is calculated
The calculation is simple. You divide the number of emails opened by the number of emails delivered, multiplying the result by 100 to get a percentage. Remember that only emails that have actually been delivered are considered, excluding bounced emails.
Here’s a practical example: if you send 20 emails and five bounce, you have 15 emails delivered. If 10 of these are open, your open rate will be: (10/15)*100 = 66.67%.
An open rate considered good ranges from 30-40%, while the range of 20-30% is considered acceptable. However, these values change depending on the sector. The religious leads with rates of up to 59.70%, followed by hobbies (53.33%) and non-profit organizations (53.21%). In contrast, sectors such as travel and transportation (22.57%) or e-commerce (31.08%) register lower rates.
Difference Between Single and Full Aperture
To properly interpret this metric, you need to know the difference between unique and total opens:
- Unique opens: These indicate how many individual subscribers opened your email, no matter how many times each one has done so.
- Total opens: Represent the total number of times your campaign was opened, including multiple opens from the same subscriber.
This distinction is fundamental to the analysis. If you carry out a campaign to 10,000 emails and you detect 5,000 openings, of which 4,000 are unique, it means that 4,000 people opened your campaign and the remaining 1,000 correspond to those who did it several times.
Relationship with other email marketing metrics
Don’t analyze open rate in isolation. Combine it with other metrics to get a complete view of performance:
- Click-through rate (CTR): Measures the percentage of recipients who clicked on a link. The average rate is around 2.66%, although it varies by industry.
- Click-through-per-open rate (CTOR): Indicates how many people clicked after opening the email.
- Conversion rate: Reflects how many recipients performed the desired action (purchase, registration, etc.).
- Bounce rate: Percentage of emails that could not be delivered.
Remember that while open rate is valuable, it has limitations. Privacy changes, such as Apple Mail Privacy Protection, automatically mark emails from Apple Mail clients as opened, artificially inflating the rates. In addition, factors such as image blocking can prevent accurate registration of openings.
For this reason, we recommend complementing the analysis with other metrics such as CTR, which is currently considered a more reliable indicator to measure real subscriber engagement.
Factors Affecting Open Rate
Getting your emails opened is no coincidence. Several specific elements determine whether your message will capture attention or be ignored in the inbox. We show you the key factors you need to control to optimize your results.
Importance of the subject of the email
The subject line of the email represents your first opportunity to grab attention. 47% of recipients make the decision to open based solely on this line. An effective subject matter must be concise, informative, and arouse the necessary interest.
The subject lines that work best are those that clearly inform about the content, while the less effective ones try to oversell. We recommend using techniques such as personalization, creating urgency (without exaggerating), and incorporating emojis strategically. Remember that exaggerations or false promises generate distrust and negatively affect future openings.
Shipping frequency and schedule
Finding the perfect balance in sending frequency is essential to keep your audience engaged. Sending too many emails decreases engagement, increases unsubscribes, and leads to spam complaints. On the other hand, insufficient frequency causes you to miss sales opportunities and reduces your visibility.
To determine the optimal timing, consider the health of your domain, the type of content, and the quality of your list. The best days are usually from Tuesday to Thursday. Avoid Mondays (when people focus on urgent emails) and Fridays (when many mentally switch off).
Adapt your strategy according to your business model: for B2B use working hours, while for B2C you can experiment with leisure hours. The most effective is to perform A/B testing by modifying only times and days to identify when your specific audience responds best.
Contact list segmentation
The data speaks for itself: segmented campaigns get 14% more opens than generic ones. Targeting allows you to:
- Control precisely who you target and what message you send
- Significantly reduce unsubscribes
- Improve deliverability by generating more interaction
- Increase customer lifetime value by up to 33%
The smaller the segment size, the greater the increase in effectiveness. Demographic segmentation (age, gender, location) is particularly effective, but you can also segment based on behavior, interests, or stage in the sales funnel.
Sender reputation and deliverability
Sender reputation works as a trust index that determines whether your message arrives successfully, is marked as spam, or is blocked entirely. This reputation is built with each shipment and depends on factors such as:
- Quality of your address list
- Relevant, non-intrusive content
- Adequate technical infrastructure
- Engagement rate of your campaigns
Maintaining a good reputation is essential. The more opens and clicks your emails receive, the better your position will be with service providers. We recommend implementing authentications such as SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to verify that your emails come from legitimate sources, significantly improving your deliverability.
Strategies to improve open rate
Once you know the factors that influence opens, it’s time to apply specific techniques that will increase your results. Below, we show you the most effective strategies step by step.
Customize the subject and preheader
Personalizing your emails makes a significant difference to users. Including the recipient’s name in the subject line can increase open rates, although it’s not the most impactful technique. In fact, 61.2% of survey participants consider it important to see their name in the subject line.
We recommend that you also take advantage of the preheader as an additional opportunity to highlight the value of your email. Top-performing campaigns are 22.58% more likely to include a custom preheader.
Use A/B testing to optimize shipments
Which issue will work best? Which design will be the most effective? The answer lies in A/B testing. This technique allows you to gauge interest between different versions of the same email.
You can try elements such as:
- Shipping schedules
- Subject lines
- Message content
- Newsletter Design
Remember that to get conclusive results, you should modify only one item at a time and use samples of the same size.
Apply double opt-in to improve list quality
Double opt-in requires the user to confirm their email after subscribing to be added to your list. Although this method makes the list grow more slowly, it guarantees genuinely interested contacts.
The benefits you get include:
- Preventing Fake Addresses
- Increase in open rates
- Improved deliverability
- Compliance with regulations such as GDPR
This translates into subscribers who are more likely to engage with your emails and less inclined to mark them as spam.
Create relevant and useful content for the reader
80.8% of consumers value receiving content tailored to their interests when they decide to open an email. To achieve this, segment your database according to criteria such as age, interests, occupation, or location.
Once your audience is segmented, generate newsletters with valuable content specific to each list. To get to know your audience better, we recommend monitoring the results of previous campaigns and conducting short surveys that identify their preferences.
Harness urgency and scarcity ethically
78.7% of consumers consider it important that a limited-time offer or discount appears in the subject line. Scarcity marketing uses psychological levers such as urgency and scarcity to incentivize actions.
The most effective techniques include:
- Countdown timers
- Limited time offers
- Flash sales
However, use these strategies with integrity, avoiding exaggerating situations to put pressure on customers. Messages should be clear and direct, especially if they contain promotions or discounts.
Common mistakes to avoid
Knowing the most frequent mistakes is as crucial as mastering the best techniques. These mistakes can ruin the months-long work of building a solid email marketing strategy.
Not cleaning the database regularly
Outdated lists are the silent enemy of your campaigns. Keeping inactive subscribers or incorrect addresses directly damages your domain’s deliverability and reputation. Dirty databases cause low open rates, bounces, and increase the chances that your emails will end up in spam.
Remember that an email list degrades annually by at least 22.71%. We recommend that you perform periodic cleanups by removing addresses that do not interact and develop specific processes to reactivate inactive users.
Send unsegmented emails
Shooting the same message to your entire database is one of the most costly mistakes. The data doesn’t lie: segmented campaigns get 14% more opens than generic ones. Ignoring segmentation leads to mass unsubscribes and destroys key indicators such as open rate.
Divide your audience into groups based on interests, behavior, or demographics. Only then will you be able to send really relevant content for each segment.
Ignoring mobile optimization
70% of emails are opened from smartphones. If your design does not adapt correctly to these devices, you will be complicating the reading and navigation of your subscribers, drastically increasing the chances of unsubscribe.
Verify that the layout, layout, and images display correctly on mobile. Text links and buttons need at least 57 pixels in width and height to allow for easy clicks.
Not respecting unsubscriber cancellations
The “unsubscribe” button should be easy to locate for those who no longer wish to receive emails. Complicating this process can lead to serious legal consequences and damage to your reputation.
Making it easy to unsubscribe helps you clean up your list of disinterested subscribers, improve your credibility, and avoid spam filters. It is a practice that benefits both parties.
