Email deliverability is a critical aspect of any business’s online communication. It refers to the ability of an email to reach the intended recipient’s inbox without being marked as spam or getting bounced back. Poor deliverability can hinder your marketing campaigns, customer interactions, and business reputation. Luckily, cPanel offers several built-in tools to ensure optimal email deliverability.
In this blog post, we’ll explore how email deliverability works in cPanel, the tools available to improve it, and why it’s essential for maintaining a healthy email communication system.

What is Email Deliverability?
Before diving into cPanel’s tools, it’s important to understand what email deliverability encompasses. Email deliverability isn’t just about sending an email successfully—it’s about getting it into the recipient’s inbox, not their spam or junk folder.
Several factors affect email deliverability:
- Sender Reputation: If your domain or IP address has a bad reputation, your emails are likely to be blocked.
- Email Authentication: Ensuring the sender is who they claim to be (via SPF, DKIM, and DMARC records).
- Email Content: Spammy language or suspicious links can trigger filters.
- DNS Configuration: Proper DNS settings, including reverse DNS and valid MX records, are crucial for deliverability.
cPanel provides easy-to-use tools to manage these factors effectively.
cPanel Tools for Enhancing Email Deliverability
- Email Deliverability Tool in cPanel
The first thing to know is that cPanel comes with a built-in “Email Deliverability” feature. It helps you identify and fix issues with your domain’s email configuration. This feature primarily checks for SPF, DKIM, and DMARC records, ensuring they are correctly set up.
How to Access the Email Deliverability Tool:
Log in to cPanel.
Scroll to the Email section.
Click on Email Deliverability.
This tool will display a list of domains hosted on your server and their current email configuration. If there are issues with SPF, DKIM, or DMARC, you’ll see error messages with suggestions for fixing them.
Understanding SPF, DKIM, and DMARC
Let’s take a deeper dive into these three critical protocols for email authentication, all of which directly affect your deliverability.
1. Sender Policy Framework (SPF)
The SPF record is a DNS record that tells receiving servers which IP addresses or servers are allowed to send emails on behalf of your domain. Without a valid SPF record, your emails may be flagged as potential spam.
How to Set Up SPF in cPanel:
- Navigate to Email Deliverability in cPanel.
- Find the domain you want to configure and click Manage.
- You will see the recommended SPF record. You can copy it and add it to your DNS settings manually if needed.
2. DomainKeys Identified Mail (DKIM)
DKIM is another email authentication technique that helps verify whether an email was sent by the owner of a domain. It works by adding a digital signature to the email header, which receiving servers can verify by checking against the sender’s DNS records.
How to Set Up DKIM in cPanel:
- Navigate to Email Deliverability.
- Select your domain and click Manage.
- If DKIM isn’t already configured, cPanel will suggest a DKIM record you can add to your DNS settings.
3. Domain-based Message Authentication, Reporting, and Conformance (DMARC)
While SPF and DKIM help verify the sender’s identity, DMARC is an additional layer of protection that tells the receiving server what to do if an email fails those checks. DMARC helps prevent phishing and spoofing attacks, which can damage your domain’s reputation.
How to Set Up DMARC in cPanel:
- You need to manually create a DMARC record in your DNS settings.
- Go to your DNS zone editor in cPanel.
- Add a new TXT record with the following format
_dmarc.yourdomain.com TXT "v=DMARC1; p=none; rua=mailto:youremail@yourdomain.com;"Replace the settings according to your preference, wherep=nonecan be changed top=rejectif you want to reject all emails that fail SPF and DKIM checks.
Improving Email Reputation with cPanel Tools
- Track IP Reputation The reputation of the IP address that your emails are sent from plays a significant role in deliverability. If your IP address is blacklisted, your emails are unlikely to be delivered. cPanel allows you to check your server’s IP address reputation and take action if it’s blacklisted.
There are third-party tools like MXToolbox that help monitor your IP reputation, and you can use cPanel’s built-in tools to change or mask the sending IP if necessary.
- Reverse DNS Configuration Another important factor is ensuring that reverse DNS (rDNS) is properly set up for your domain. Reverse DNS helps email servers verify your domain and IP address, improving your email deliverability. If your server doesn’t have an rDNS record, it can negatively impact email delivery, as some receiving servers may consider emails from such servers to be untrustworthy.
You can set up rDNS by contacting your hosting provider and requesting it for your server’s IP address.
Conclusion
Ensuring email deliverability is vital for successful communication, whether you’re running a personal blog, an eCommerce store, or a large corporation. cPanel simplifies the process by providing essential tools like the Email Deliverability interface, SPF, DKIM, and DMARC record management, along with tools to track email performance and IP reputation.
By configuring these features properly, you can significantly improve your domain’s email deliverability, ensuring that your emails reach their intended audience. Regularly monitoring and adjusting these settings will help you avoid common pitfalls and maintain a positive sender reputation.
Effective email communication is a key pillar of any business. Don’t let poor deliverability hold you back—use cPanel’s robust email tools to stay ahead!
