Email open rates are the percentage of recipients who open an email campaign out of the total number of recipients who received the email. Emails are a crucial metric for measuring the effectiveness of an email marketing campaign in capturing recipients’ attention and engaging them with the content.

Email open rate provides valuable insights into the performance of an email campaign and for optimizing future campaigns for better engagement. 

Higher open rates generally indicate that recipients found the email subject line and preview compelling enough to open the email.

It offers a direct and personalized channel to reach potential and existing customers, allowing companies to deliver targeted messages, promotions, updates, and valuable content directly to their audience’s inbox.

The effectiveness of email campaigns depends on how those messages are received and interacted with by recipients. This is where email open rates come into play. Here are some of the reasons that make open rates an important metric.

What is the Email Click Rate?

The Email click rate or click-through rate (CTR) for emails, is a metric used in email marketing to measure the effectiveness of an email campaign. It represents the percentage of email recipients who clicked on one or more links within an email message.

Higher click rates often indicate that your content aligns well with the interests and needs of your subscribers.

Methods for Tracking Email Opens 

Tracking Email opens is a crucial aspect of email marketing analytics. Here are several methods used to monitor email opens and their explanations.

1. Tracking Pixels

Tracking pixels are tiny, invisible images embedded within the email’s HTML code. When a recipient opens the email, this image request is recorded by the server, indicating that the email has been opened. 

Advantage – Tracking pixels provide accurate data on email opens and are widely used by email marketing platforms.

Limitation –  Some email clients block images by default, which can result in underreporting of open rates.

2. Read Receipts 

Read Receipts typically function by embedding a special request within the email header. When the recipient opens the email, their email client may send a notification back to the sender’s email server, indicating that the email has been opened.

Advantage – provides direct confirmation of email opens, though it relies on recipient action.

Limitation – Read receipts depend on recipient consent and may not be supported by all email clients. 

3. Unique URLs

This method generates a unique URL for each recipient within an email campaign. When a recipient clicks on their unique URL, it signals that the email has been opened. The server logs the open event, allowing marketers to track which recipients have opened the email.

Advantage – This method offers accurate tracking, regardless of whether images are loaded, as it relies on URL clicks.

Limitation – Generating unique URLs for each recipient can be complex and impractical for large email lists. 

4. Software or Tools 

There are several tools to track email open rates and other email metrics. When choosing a tool, consider factors such as ease of use, pricing, integration options, and the specific features and functionality that meet your needs. 

 Here are some of the popular tools

Reason for Low Email Open Rate

There can be several different reasons that a marketer may face in an email marketing campaign that decrease the effectiveness and engagement of the recipients. Here are some of the common reasons marketers encounter. 

1. Email Content Quality 

The quality and relevance of email content greatly influence open rates. If the email contains irrelevant, uninteresting, or poorly formatted content, recipients are less likely to engage with them. 

2. Sender Reputation 

Recipients are more likely to open emails from those senders they trust and recognize. If your sender’s reputation could be better due to previous spam complaints or a low engagement rate, your emails may end up in the recipient’s spam folders or be ignored. 

3. Email Frequency 

Sending too many emails to recipients can lead to less email engagement. Overly frequent emails may cause recipients to ignore or unsubscribe from future communications, resulting in lower open rates.

4. Lack of Personalisation 

Personalized email that addresses the recipient by name and offers content tailored to their preferences tends to perform better than generic mass emails. Lack of personalization can lead to lower open rates as recipients may perceive emails as irrelevant.

5. Competition 

In a crowded market or industry, recipients may receive numerous emails about a specific area competing for attention. In such scenarios, standing out from the competition becomes challenging, leading to lower open rates.

6. Email List Quality

An outdated or poorly maintained email can lead to low open rates. If your email list contains invalid or inactive email addresses, your emails won’t reach their intended recipients, impacting open rates. 

7. Deliverability Issues 

Technical issues such as email bounces, spam filtering, or blacklisting can hinder email deliverability and reduce open rates. Ensuring proper email authentication, maintaining a clean email list, and practicing best practices can help mitigate deliverability issues.

Strategies to Improve Open Rate

1. Creating Relevant and Clear Content

Keep your email content clear, concise, and short, and focus on the important information to grab recipients’ attention and encourage them to open and read further. 

Personalize your emails with recipients’ names or other relevant information to make them feel more tailored and increase the likelihood of engagement.

2. Identify Audience

Identifying an audience is a crucial strategy for improving email open rates. Gather data about your subscribers, including interests, past behavior, and engagement with previous emails. 

Use surveys and feedback forms to gather information directly from your subscribers about their preferences, interests, and challenges. This can help to you resonate with them through your email content. 

3. Compelling Subject Lines 

Craft attention-grabbing subject lines that create a sense of urgency, or offer a benefit to encourage them to open your emails. Maintain consistency with your brand voice and messaging style to ensure your subject lines align with recipients’ expectations and build trust.

Here are some of the Tips to craft a compelling subject line 

  • Pose a question 
  • Use personalization 
  • Avoid spammy language 
  • Highlight benefits or offers 
  • Stay true to brand voice 

4. Optimize Send Time 

Determine the timing for sending your emails by analyzing past performance data and considering factors like recipients’ time zones and typical email-checking habits. 

Consider scheduling your emails to arrive at times that are convenient for recipients in each time zone. This ensures that emails are received when recipients are most likely to be checking their inboxes.

5. Maintain Sender Reputation 

Sending relevant, valuable content and practicing best email practices helps to maintain a positive sender reputation. It helps in increasing the open rates of email and builds trust among recipients. 

6. Segmentation of Email List 

Segment your audience email list based on relevance, and past behavior to send more targeted and relevant content to specific audience segments. 

Segmentation can also help marketers deliver emails at optimal times, as different segments may have varying email-checking habits and preferences.

By implementing these strategies or a combination of strategies email open rate increases and helps in overall engagement in your email marketing campaigns. Remember to monitor your performance and adjust your approach as needed.  


In conclusion, email open rates serve as a crucial barometer of the effectiveness of email marketing campaigns. Understanding and leveraging email open rates will remain essential for businesses seeking to maximize the impact of their marketing campaigns.
