Understanding and Implementing DMARC for Enhanced Email Security

[Dynaweb]

What is DMARC?
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol designed to protect your domain from email spoofing. It helps verify that emails claiming to originate from your domain are indeed sent by you or an authorized sender.  

Why is DMARC Important?

• Enhanced Email Deliverability: Emails with proper DMARC authentication are more likely to reach recipients' inboxes, reducing spam filtering issues.
• Protection Against Phishing: DMARC helps prevent unauthorized use of your domain for phishing attacks.
• Increased Trust: Implementing DMARC demonstrates your commitment to email security, building trust with your recipients.

When to Implement DMARC
While often associated with email marketing platforms like Mailchimp, Constant Contact, or HubSpot, DMARC is equally beneficial for businesses sending emails from their own hosted email servers. If you're concerned about email spoofing or want to improve email deliverability, DMARC is a valuable tool.

Setting Up DMARC
Implementing DMARC involves adding specific records to your domain's DNS settings. This is often performed through your server control panel such as cPanel or Plesk, but could also be through your DNS management at your domain registrar if your nameservers point to them and your DNS is managed there (less common). It's essential to follow the specific instructions provided by your service provider.

Important Considerations:

• Backup Your DNS Records: Before making any changes to your DNS settings, create a backup of your current records. It is sufficient to perform a full domain backup using cPanel or Plesk, but you may also want to screenshot your current records before performing any changes or additions to DNS records for good practice.
• Test Your Emails: After implementing DMARC, closely monitor your email delivery rates for any potential issues.
• Seek Support: If you encounter difficulties, consult your email provider for assistance or open a ticket with us.

By understanding and implementing DMARC, you can significantly enhance your email deliverability trust level, reputation, and security.
