Email marketing is one of the most effective ways to reach out to customers and potential clients. However, if your emails are not being delivered, your marketing efforts will fall flat. That’s where email deliverability comes in. Deliverability refers to the ability of your emails to reach the intended recipient’s inbox. In this article, we’ll explore the best practices for email deliverability, common issues that affect it, and proven strategies for improving email deliverability.

Understanding Email Deliverability Best Practices

Before diving into strategies for improving email deliverability, it’s important to understand some best practices. These practices ensure that your emails are more likely to reach the intended recipient’s inbox and not end up in spam or junk folders.

Firstly, ensure that your email list is clean and up-to-date. Remove inactive subscribers and those who have unsubscribed. Additionally, avoid purchasing email lists as these are often filled with invalid email addresses and can harm your sender reputation.

Secondly, always obtain permission before sending emails. This can be done through an opt-in process where subscribers voluntarily provide their email addresses. This ensures that your emails are targeted and relevant to the recipient, increasing the likelihood of them opening and engaging with your email.

Thirdly, ensure that your emails are well designed and formatted for easy reading. Use a clear subject line that accurately reflects the content of the email. Additionally, avoid using excessive capitalization and special characters as these are often associated with spam and can harm your deliverability.

Common Issues that Affect Email Deliverability

There are several common issues that can affect email deliverability. These include:

Spam Filters

Spam filters are designed to identify and block emails that are likely to be spam. To avoid being marked as spam, ensure that your emails are well-designed, contain relevant content, and are sent to a targeted audience. Additionally, avoid using spam trigger words such as “free” or “buy now” in your subject line.

Sender Reputation

Your sender reputation is a score assigned to your IP address based on your email sending history. A poor sender reputation can result in emails being blocked or sent to the spam folder. To maintain a good sender reputation, ensure that you are sending relevant, targeted emails to a clean and engaged email list.

Email Authentication

Email authentication is the process of verifying that an email is legitimate and not forged. This is done through technologies such as SPF, DKIM, and DMARC. Failure to authenticate your emails can result in them being blocked or sent to the spam folder.

Proven Strategies for Improving Email Deliverability

Now that we’ve covered best practices and common issues that affect email deliverability, let’s explore some proven strategies for improving it.

Segment Your Email List

Segmenting your email list involves dividing it into smaller groups based on specific characteristics such as demographics or behavior. This allows for more targeted and relevant emails to be sent, resulting in higher engagement and deliverability.

Monitor Your Sender Reputation

Regularly monitoring your sender reputation allows you to address any issues that may be affecting it. Keep track of your email metrics such as open rates and click-through rates, as well as any spam complaints or bounces.

Use Email Authentication Technologies

Implementing email authentication technologies such as SPF, DKIM, and DMARC can help to verify your email’s legitimacy and improve deliverability. These technologies work together to prevent email spoofing and ensure that your emails are delivered to the intended recipient.

Test Your Emails

Regularly testing your emails ensures that they are well-designed, formatted correctly, and free from errors. It also allows you to identify any issues that may be affecting deliverability, such as broken links or images.

Monitor Your Email Content

The content of your email can also affect deliverability. Avoid using spam trigger words, excessive capitalization, and special characters. Additionally, include a clear call-to-action that encourages engagement and avoids making false claims or promises.


Improving email deliverability is essential for the success of your email marketing campaigns.
