Email DNS Records: How to Set Them Up for High Deliverability

In the vast landscape of the internet, DNS (Domain Name System) records serve as the internet’s phonebook, translating human-readable domain names (like yourcompany.com) into machine-readable IP addresses. For successful email communication, and especially for robust email marketing, these records are absolutely crucial. Without correctly configured email DNS records, your marketing campaigns, transactional emails, and even internal communications might never reach their intended recipients, often ending up in spam folders or being rejected outright.

Here’s why properly configured email DNS records are paramount for your email deliverability:

Authentication: Records like SPF, DKIM, and DMARC are essential for verifying the legitimacy of your emails. They provide clear signals to receiving mail servers that your emails genuinely originate from your domain, effectively preventing spoofing and phishing attempts.

Deliverability: Strong email authentication builds trust with email providers. When your emails are authenticated, they’re far less likely to be flagged as spam, leading to significantly higher inbox placement rates.

Reputation:  Implementing reliable and precise email authentication methods strengthens your domain’s sender reputation. A solid reputation directly translates to improved deliverability and more effective email campaigns.

Compliance: Many email service providers and anti-spam organizations now strongly recommend or even require specific email DNS records for legitimate email sending. Adhering to these standards is essential for long-term email success.

Key Email DNS Record Types

Let’s explore the primary types of DNS records relevant to email authentication:

TXT (Text) Records

These versatile records serve various purposes, including housing:

DKIM (DomainKeys Identified Mail) Records: DKIM adds a digital signature to your outgoing emails, allowing the recipient’s server to verify that the email has not been tampered with and genuinely originated from your domain.

SPF (Sender Policy Framework) Records: An SPF record lists the mail servers explicitly authorized to send email on behalf of your domain. If an email claims to be from your domain but originates from an unlisted server, it’s highly likely to be marked as spam. If you use an external service to send mail, you might only need to include:spf.yourservice.com in your existing SPF record.

DMARC (Domain-based Message Authentication, Reporting, and Conformance) Records: DMARC builds upon SPF and DKIM, giving you control over actions taken for emails that fail authentication. You can instruct receiving servers to quarantine, reject, or simply report on such emails, offering valuable insights into potential abuse. If a DMARC record already exists in your DNS panel, avoid adding a duplicate entry.

OWNERSHIP Records: This type of TXT record is often used by platforms to verify domain ownership, helping prevent fraudulent activity.

CNAME (Canonical Name) Records

While not directly used for email routing, CNAME records are frequently used for:

Tracking Domains: A custom CNAME record can create a branded subdomain (e.g., cma.yourdomain.com) to mask default tracking URLs used by email marketing platforms (like click.emailplatform.com). This enhances brand consistency and can sometimes improve deliverability by avoiding generic tracking links.

How to Add Email DNS Records (Step-by-Step)

Adding email DNS records typically involves logging into your domain registrar or DNS hosting provider’s control panel. While the exact interface may vary, the core steps remain consistent. Always refer to your specific email marketing platform’s documentation for the precise values you need to enter for SPF, DKIM, and DMARC records.

General Steps:

1. Identify Your DNS Hosting Provider: This is usually where you registered your domain (e.g., GoDaddy, Namecheap) or where your nameservers are pointed if you’re using a separate DNS management service like Cloudflare.
2. Log in to Your DNS Hosting Provider’s Control Panel: Navigate to the section for managing your domain’s DNS settings, often labeled “DNS Management,” “Zone File Editor,” or “Advanced DNS.”
3. Add New Records: Look for an option to “Add Record” or “Add New DNS Record.”
4. Select the Record Type: Choose the appropriate record type (e.g., TXT, CNAME).
5. Enter the Details: Carefully input the “Host,” “Value,” and “TTL” (Time To Live) as provided by your email marketing platform.
6. Click to apply and store the updated DNS record settings.
7. Wait for Propagation: DNS changes can take anywhere from a few minutes to 48 hours to propagate across the internet. You can use online DNS lookup tools (like MXToolbox) to check if your records have been updated.

• Access DNS Settings: Find the “DNS Management,” “Zone Editor,” or “Advanced DNS” section in your hosting control panel (e.g., cPanel, Plesk).
• Locate “Add Record”: This is usually a clearly labeled button or link.
• Input Record Details: For each record (SPF, DKIM, DMARC, CNAME):
  • Type: Select the correct record type.
  • Host/Name: This is usually @ for the root domain or a specific subdomain (e.g., _dmarc).
  • Value/Content/Points to: This is the actual data string provided by your email marketing platform.
  • TTL (Time To Live): How long DNS resolvers should cache the information. Often set to a default (e.g., 3600 seconds or 1 hour).
• Save: Apply the changes.
