Common Email Domain Issues

Email domain issues can significantly disrupt communication with your customers and partners. To prevent or resolve these problems, collaborate with your IT department. Below are some common email domain issues that may require attention:

• Has your email domain been impacted by Breach?: Use a secure password and enable two-factor authentication (2FA). Regularly check for breaches and change compromised passwords.

• Is your email domain missing MX/SPF/DNS Records?: Ensure proper mail exchange (MX) records, sender policy framework (SPF), and domain name system (DNS) configurations are in place to validate your domain for email delivery.

• Are you using a Disposable/Free Email Service?: Use a verified, reputable email provider associated with your business domain.

• Invalid Domain: Register your domain properly, and ensure it is active.

• Risky TLDs: Opt for more trusted top-level domains (TLDs) such as .com, .org, or .net to reduce the risk of being flagged.

• Missing ICANN Suffix: Verify that your domain includes a valid ICANN suffix, confirming its registration.

• Alias Email Address: Use a direct, non-alias email address for important communications to reduce suspicion.

There are public tools and databases that can help verify email addresses and domains against some of those criteria. For example:

• Have I Been Pwned ( https://haveibeenpwned.com/): Checks if an email address has been involved in any breaches.
• MXToolbox ( https://mxtoolbox.com/): Validates MX, SPF, and DNS records.
