Email Marketing Hacks: 8 Mistakes That Tank Your Open Rates

by | Oct 13, 2023


Email marketing is a powerful tool for businesses to connect with their audience, drive engagement, and increase sales. However, it’s not just about sending emails; it’s about sending the right emails to the right people at the right time. One crucial metric that measures the success of your email campaigns is the open rate. If your emails aren’t being opened, all your efforts go in vain.

In this blog post, we’ll explore 8 common mistakes that can tank your email open rates and provide you with hacks to overcome them.

Neglecting Your Subject Line (Hack: Craft Irresistible Subject Lines):

The subject line is the first thing recipients see in their inbox. If it doesn’t grab their attention, they’ll likely ignore your email. Avoid generic or misleading subject lines and instead opt for something intriguing, personal, or time-sensitive. Use action-oriented language and keep it concise (under 50 characters if possible). A/B testing subject lines can help you find what resonates best with your audience.


Sending Emails at the Wrong Time (Hack: Know Your Audience’s Schedule):

Sending emails at the wrong time can result in them getting buried in crowded inboxes. Research your audience’s behavior to determine when they are most likely to check their emails. Tools like email schedulers can help you time your emails for maximum impact. Consider time zones if your audience is global.


Overloading Subscribers with Emails (Hack: Segment and Target):

Bombarding subscribers with too many emails can lead to email fatigue and increased unsubscribe rates. Segment your email list based on factors like demographics, purchase history, or engagement level. Send targeted emails to each segment at a frequency that suits their preferences. This personalized approach can significantly improve open rates.


Ignoring Mobile Optimization (Hack: Design for Mobile):

With the majority of email opens occurring on mobile devices, it’s crucial to ensure your emails are mobile-friendly. Use responsive email design to ensure your emails look good and are easy to read on all screen sizes. Test your emails on various devices before sending them out.


Failing to Build Trust (Hack: Establish Trustworthy Sender Reputation):

Your sender reputation can impact whether your emails end up in the inbox or spam folder. To build trust, use a recognizable sender name and email address. Authenticate your domain and use proper email authentication protocols like SPF and DKIM. Encourage recipients to add you to their address book.


Neglecting Email List Maintenance (Hack: Regularly Clean Your List):

Over time, email lists can accumulate inactive or invalid email addresses. These can hurt your open rates and email deliverability. Regularly clean your email list by removing bounced or unsubscribed email addresses. Consider re-engagement campaigns for dormant subscribers before removing them from your list entirely.


Ignoring Email Preview Text (Hack: Craft Compelling Previews):

The email preview text, often displayed alongside the subject line, can impact open rates. Don’t leave it blank or use default text. Craft compelling preview text that complements your subject line and entices recipients to open your email. This is another element that can benefit from A/B testing.


Lack of Personalization (Hack: Personalize Your Content):

Generic, one-size-fits-all emails are less likely to capture the attention of your subscribers. Use personalization techniques to tailor your content to each recipient’s preferences and behavior. Incorporate their name, recommend products based on past purchases, or send personalized offers. Personalization shows that you value your subscribers and their interests.



Improving your email open rates requires careful attention to detail and a commitment to delivering value to your subscribers. By avoiding these common mistakes and implementing the hacks provided, you can significantly increase the chances of your emails being opened, read, and acted upon. Remember, email marketing is not just about sending messages; it’s about building and nurturing relationships with your audience through meaningful and relevant content.
