Best Practices for Maximizing Email Deliverability with Mailerlite

Improving your email deliverability isn’t a one-time task—it requires consistent efforts and a meticulous approach.

Thankfully, Mailerlite vast array of features is designed to make this task more manageable. Let’s explore some of these practices in detail.

Maintaining a Clean Email List

An email list is the lifeblood of your email marketing efforts. However, a more extensive list isn’t necessarily better. Having a clean, high-quality email list matters when it comes to email deliverability.

A clean email list is free from invalid, inactive, or unengaged email addresses. These low-quality addresses don’t just waste your resources—they can harm your sender reputation, leading ISPs to flag your emails as spam.

So, how does Mailerlite help maintain a clean email list?

It starts with robust double opt-in features. When subscribers must confirm their email addresses, you ensure your list is free from invalid addresses.

But Mailerlite doesn’t stop there. It offers detailed analytics about bounce rates and subscriber engagement.

image 530

These insights allow you to identify and prune unengaged or bouncing addresses from your list.

Moreover, Mailerlite automation tools help manage inactive subscribers.

You can set up automated re-engagement campaigns targeting subscribers who haven’t interacted with your emails. If they remain unengaged, Mailerlite allows you to remove them from your list easily.

By leveraging these features, you can maintain a clean, high-quality email list—an essential step toward maximizing email deliverability.

Improving Sender Reputation

Understanding and Improving Sender Reputation

Sender reputation is a significant metric ISPs use to decide whether your email should land in the inbox or spam folder. It is like a credit score for your email deliverability.

A high sender reputation increases your email deliverability rate, while a low score may mark your emails as spam.


Factors influencing your sender reputation include bounce rates, spam complaints, email volume, and recipient engagement. Mailerlite provides valuable tools to monitor and manage these factors, improving your sender reputation.

Mailerlite analytics dashboard gives you real-time insights into bounce rates and engagement levels. By closely monitoring these metrics, you can proactively address issues and prevent them from damaging your sender reputation.

Additionally, Mailerlite automation tools can be used to manage email volume effectively. By scheduling your email campaigns, you avoid sending too many emails simultaneously—a red flag for ISPs.

Mailerlite A/B testing feature helps optimize your email content and subject lines, improving open and click-through rates and boosting your sender reputation.

Mailerlite feedback loop integration helps you keep track of spam complaints. If a subscriber marks your email as spam, you’re notified immediately, allowing you to remove the subscriber from your list and prevent further damage to your sender reputation.

Creating Email Content

Creating Engaging Email Content

It’s not just about getting your email into the inbox; it is also about ensuring your emails are opened, read, and engaged with.

The more engaging your content, the higher your open and click-through rates, and the better your email deliverability.

Mailerlite is a pro for helping you create captivating email content. It comes with a range of features that ensure your emails look good and resonate with your audience.

The platform offers a drag-and-drop editor that allows you to design professional-looking emails without any coding skills.

This, coupled with a library of customizable templates, enables you to create visually appealing emails that capture your audience’s attention.

But what makes content truly engaging is personalization, and Mailerlite excels at this.

With its dynamic content feature, you can customize your emails based on your subscribers’ information, ensuring that your messages resonate on a personal level.

image 532

Additionally, Mailerlite A/B testing feature lets you experiment with different subject lines, content layouts, and call-to-actions to find what works best for your audience.

This feature ensures your emails are engaging and optimized for maximum response.

Lastly, the platform rich media options allow you to incorporate videos, images, and interactive elements into your emails, making them more engaging and interactive.

With Mailerlite, creating engaging email content is not a daunting task—it is a creative journey that leads to improved email deliverability and successful email marketing campaigns.

Email List Segmentation

Proper Email List Segmentation

One-size-fits-all is a term that rarely applies in successful email marketing. Your audience is diverse, with different needs, interests, and behaviors.

Treating them all the same is a surefire way to diminish engagement and harm your email deliverability. Enter the power of email list segmentation.

Email list segmentation is dividing your email list into smaller, more targeted groups based on various criteria like demographics, past purchases, browsing behavior, and email engagement.

The result? More personalized and relevant emails that your audience is more likely to engage with.

Mailerlite makes the task of segmentation straightforward and effective. It offers a flexible segmentation feature that lets you categorize your subscribers based on various criteria.

Whether it is location, engagement level, or custom fields, you can easily tailor your segments to align with your marketing strategy.

image 533

But Mailerlite goes beyond basic segmentation. Its advanced segmentation feature allows for more complex criteria based on combinations of conditions. This means you can target particular groups, like users who clicked on a particular link in your last email but didn’t make a purchase.

You can create more targeted and personalized campaigns with the right segments in place.

This improves engagement and minimizes the chances of your emails being marked as spamboosting your email deliverability.

In essence, Mailerlite empowers you to tap into the power of segmentation, ensuring your emails hit the mark every time.

The result?

A better relationship with your audience and a higher email deliverability rate.
