Why Check DNS Records for Email Deliverability?

Email Deliverability & DNS Configuration

Properly configured DNS records ensure your emails reach their destination. Missing or misconfigured MX, SPF, DMARC, and DKIM records can cause delivery failures and spam filtering.

• MX records direct email to the correct mail servers
• SPF records prevent email spoofing and phishing
• DMARC records define email authentication policies
• DKIM records add digital signatures for verification

Security & Authentication

DNS records like SPF, DKIM, and DMARC help protect your domain from phishing attacks and ensure email authenticity.

• DKIM adds digital signatures to emails
• SPF specifies authorized sending servers
• DMARC provides reporting and enforcement

How to Interpret Your DNS Results

What do the status indicators mean?

✓ Found: This record type is properly configured on your domain. This is good for email deliverability.

✗ Not found: This record type is missing from your domain. This could negatively impact your email deliverability and security.

What if my MX records are missing?

Critical Issue: Without MX records, your domain cannot receive email. This is essential for any domain that needs to receive email.

Impact: All emails sent to your domain will bounce back to the sender.

Solution: Contact your domain registrar or DNS provider to add MX records pointing to your email server.

What if my SPF record is missing?

Important Issue: SPF records prevent email spoofing by specifying which servers are authorized to send email from your domain.

Impact: Your emails may be flagged as spam, and your domain is vulnerable to spoofing attacks.

Solution: Add an SPF record like:v=spf1 include:_spf.google.com ~all

What if my DMARC record is missing?

Recommended: DMARC records tell receiving servers how to handle emails that fail SPF or DKIM authentication.

Impact: Without DMARC, you won't receive reports about authentication failures, and you have less control over email handling.

Solution: Start with a monitoring policy:v=dmarc1; p=none; rua=mailto:dmarc@yourdomain.com

What if my DKIM record is missing?

Recommended: DKIM adds a digital signature to your emails to prove they weren't altered in transit.

Impact: Your emails may be treated with less trust by receiving servers, potentially affecting deliverability.

Solution: DKIM setup varies by email provider. Contact your email service provider for specific instructions.

What's the difference between A and AAAA records?

A Records: Point your domain to IPv4 addresses (like 192.168.1.1). Most domains have these for basic website hosting.

AAAA Records: Point your domain to IPv6 addresses (like 2001:db8::1). These are newer and provide better performance but aren't required for email.

For Email: A/AAAA records are mainly used for webmail interfaces. They don't directly affect email deliverability.

How do I fix DNS record issues?

1. Contact Your Provider: Reach out to your domain registrar, DNS provider, or email service provider.

2. Use Their Tools: Most providers have DNS management tools in their control panels.

3. Wait for Propagation: DNS changes can take up to 48 hours to propagate globally.

4. Re-check: Use this tool again after making changes to verify they're working.

What's a good email deliverability score?

Excellent (90-100%): All essential records present (MX, SPF, DMARC, DKIM)

Good (70-89%): MX and SPF present, missing DMARC or DKIM

Fair (50-69%): MX present, missing SPF

Poor (0-49%): Missing MX records or critical authentication records
