Ensuring your emails reach the inbox and don’t get caught in spam filters is critical for effective communication. At Govaio.com, we know how important it is for your emails—whether marketing campaigns, transactional messages, or personal correspondence—to be trusted and accepted by receiving mail servers.
The Email Deliverability interface in cPanel is your go-to tool for diagnosing and fixing common email authentication problems related to DKIM, SPF, and PTR (Reverse DNS) records. Properly configured, these records drastically increase your email acceptance rate and reduce spam labeling.
This comprehensive guide will walk you through:
- What Email Deliverability means
- Understanding DKIM, SPF, and PTR records
- How to use the cPanel Email Deliverability interface
- Common problems and how to solve them
- Best practices for flawless email sending from your Govaio hosting
What Is Email Deliverability?
Email deliverability refers to the ability of your emails to successfully reach the recipients' inboxes without being blocked, bounced, or flagged as spam. High deliverability means your emails are trusted by recipient mail servers and ISPs.
Poor deliverability can result in:
- Important emails landing in spam/junk folders
- Emails getting blocked entirely
- Reduced customer engagement and lost business opportunities
At Govaio.com, we empower you with tools and knowledge to maximize deliverability through proper DNS configurations.
Key Authentication Records Explained
1. SPF (Sender Policy Framework)
SPF specifies which mail servers are authorized to send email on behalf of your domain. When a recipient server receives an email, it checks your SPF record to verify if the sending server’s IP is allowed.
- Purpose: Prevents email spoofing and phishing.
- How it works: SPF is a TXT DNS record listing authorized IP addresses.
2. DKIM (DomainKeys Identified Mail)
DKIM uses cryptographic signatures to verify that the email message was sent by an authorized sender and was not altered in transit.
- Purpose: Confirms message integrity and authentic origin.
- How it works: Adds a digital signature linked to your domain in email headers. Recipient servers check this signature against your DNS public key.
3. PTR (Pointer or Reverse DNS Record)
PTR records map an IP address back to a domain name.
- Purpose: Ensures the sending IP can be resolved to a domain, improving trust.
- How it works: Recipient servers perform a reverse DNS lookup to verify the IP is associated with your domain.
How to Use the Email Deliverability Interface in cPanel
- Log into your Govaio.com cPanel account.
- Scroll down to the Email section.
- Click on Email Deliverability.
- Select the domain you want to check.
- The interface will display the status of your DKIM, SPF, and PTR records.
- If there are issues, cPanel provides recommended fixes and allows you to regenerate missing records.
Common Problems and How to Solve Them
Problem 1: SPF Record Missing or Incorrect
Symptoms:
- Emails marked as spoofed or spam
- Bounce-back messages mentioning SPF failure
Solution:
- Use the Email Deliverability tool to view your SPF record.
- Regenerate or manually update the SPF TXT record in your DNS zone to include all servers that send email for your domain.
- A typical SPF record looks like this:
v=spf1 a mx ip4:123.45.67.89 include:_spf.google.com ~all
- Tip: Use the include: mechanism to authorize third-party services like G Suite or Mailchimp.
Problem 2: DKIM Not Configured or Invalid
Symptoms:
- Email recipients see warnings about tampering
- Emails rejected or flagged as suspicious
Solution:
- Use cPanel Email Deliverability to check your DKIM record status.
- If missing, click Generate Local DKIM Key to create the necessary DNS TXT record.
- Add the generated public key TXT record to your domain’s DNS zone.
- Wait for DNS propagation (can take up to 48 hours).
- Verify using online DKIM tools or by sending a test email to services like Gmail.
Problem 3: PTR Record Missing or Incorrect
Symptoms:
- Emails bounce with messages about reverse DNS failure
- Some mail servers refuse connections from your IP
Solution:
- PTR records are controlled by the hosting provider or datacenter.
- Contact Govaio.com support at +91-657-3599171 to verify or request PTR configuration.
- Ensure your server IP resolves back to your domain name.
- This step is crucial for dedicated IPs; shared IPs typically have PTR set by the provider.
Advanced Tips for Optimal Email Deliverability
- Use consistent “From” addresses tied to your authenticated domains.
- Monitor blacklists regularly to ensure your IP is not flagged.
- Implement DMARC (Domain-based Message Authentication, Reporting & Conformance) policies to enforce SPF and DKIM and get reports on spoofing attempts.
- Avoid spammy content and large attachments.
- Regularly check Email Deliverability in cPanel after making DNS changes.
