Understanding Email Deliverability in cPanel

Email deliverability refers to the successful delivery of emails to the recipient's inbox without being marked as spam or bounced back. In cPanel, a popular web hosting control panel, you have the tools and settings to optimize your email deliverability and enhance your email campaigns.

When you set up email accounts in cPanel, it is essential to configure various records and settings, such as SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records. These records play a crucial role in verifying the authenticity of your emails, reducing the chances of your messages being marked as spam by receiving email servers.

However, some users might encounter challenges or confusion when dealing with email deliverability in cPanel, particularly if they don't see specific options or face mail delivery problems. In this guide, we will cover the steps to optimize email deliverability and address common issues to ensure smooth communication through cPanel.

Setting Up SPF and DKIM Records in cPanel

SPF and DKIM are essential email authentication methods that help ensure the validity and authenticity of your emails. Setting up these records correctly is a critical step in optimizing your email deliverability in cPanel.

1. SPF (Sender Policy Framework) Records:

SPF records specify which mail servers are authorized to send emails on behalf of your domain. It helps prevent email spoofing and improves your email deliverability. To set up SPF records in cPanel, follow these steps:

Step 1: Log in to your cPanel account.

Step 2: In the Mail section, click on "Email Deliverability."

Step 3: Click on "Manage" next to the domain you want to configure.

Step 4: Under the SPF section, choose the appropriate settings. You can use the default "Only use the hostname" or select "I will manually manage my SPF record."

Step 5: If you choose manual management, add the SPF record provided by your email service provider or web host.

Step 6: Click on "Update Email Deliverability" to save your SPF record.

2. DKIM (DomainKeys Identified Mail) Records:

DKIM adds a digital signature to your outgoing emails, allowing receiving servers to verify the authenticity of the messages. To set up DKIM records in cPanel, follow these steps:

Step 1: Log in to your cPanel account.

Step 2: In the Mail section, click on "Email Deliverability."

Step 3: Click on "Manage" next to the domain you want to configure.

Step 4: Under the DKIM section, enable DKIM by clicking on the toggle button.

Step 5: Click on "Enable Email Deliverability" to activate DKIM for your domain.

Common Email Deliverability Issues and Solutions

Despite configuring SPF and DKIM records correctly, some users might still experience email deliverability issues. Let's address some of the common problems and their solutions:

1. Emails Going to Spam Folder:

If your emails are consistently landing in the recipient's spam folder, it could be due to various factors, such as poor content quality, excessive use of spam-triggering words, or a low sender reputation. To improve email deliverability and avoid the spam folder:

  • Focus on sending relevant and valuable content to your subscribers.
  • Avoid using spam-triggering words and phrases in your email subject lines and content.
  • Keep your mailing list updated and engaged to improve your sender reputation.

2. Emails Not Being Received:

If your recipients are not receiving your emails at all, there could be issues with your email server configuration, DNS settings, or the recipient's mail server blocking your emails. To troubleshoot this problem:

  • Check your cPanel email settings for any misconfigurations or errors.
  • Ensure that your DNS records, including MX records, are correctly configured.
  • Ask your recipients to check their email filtering settings, including any email rules or blacklisting that may be affecting your emails.

3. Mail Delivery Delay:

Email delivery delays can be caused by various factors, including network congestion or issues with the recipient's mail server. However, if the delays persist, consider the following steps:

  • Check your email server's outgoing mail queue for any bottlenecks or delays.
  • Investigate the recipient's mail server for any performance issues that could be causing the delay.
  • Consider using a third-party email delivery service to ensure faster and more reliable email delivery.


Email deliverability in cPanel is a critical aspect of efficient communication, whether for personal or business purposes. By setting up SPF and DKIM records correctly and addressing common email deliverability issues, you can ensure that your emails reach their intended recipients and enhance your overall email marketing success. Remember to keep your email content engaging and relevant, maintain a healthy sender reputation, and regularly monitor and optimize your email deliverability settings in cPanel for the best results.
