MX Record

Definition

The mail server queries DNS for the recipient’s domain’s MX records to ensure deliverability, prevent bounces, and maintain communication. Proper MX record setup in email marketing ensures prompt delivery to subscribers’ inboxes.

How you can use

Example

Ensuring correct email delivery involves configuring MX records,, for example, if you handle email marketing.

  1. Access DNS Settings: Please log in to the domain registrar or hosting provider where you manage your DNS settings.
  2. Locate MX Records: Find the section for managing DNS records and locate the MX records.
  3. Add/Edit MX Records: Ensure that the MX records point to the correct mail servers. For instance:
    • Priority: 10, Mail Server: mail1.example.com
    • Priority: 20, Mail Server: mail2.example.com

Here’s how an MX record configuration might look:

Copy codeexample.com.    IN    MX    10    mail1.example.com.
example.com.    IN    MX    20    mail2.example.com.

Benefits

  • Improved Deliverability: Correct MX records direct emails properly, minimizing bounces and delivery issues.
  • Redundancy: Multiple MX records with different priorities provide a backup in case the primary mail server is unavailable.
  • Spam Prevention: Optimal MX configurations authenticate sending domains, decreasing spam risk.

Calculation

While there are no specific formulas for configuring MX records, following best practices and using priority values correctly are key. Mail servers prioritize based on value, with lower values getting top priority. Tools like MXToolbox can help verify and troubleshoot MX record configurations.

Key Takeaways

  2. Enhance Deliverability: Proper MX records reduce bounce rates and improve email deliverability.
  3. Provide redundancy: Use multiple MX records to ensure emails are delivered even if one server fails.
