Mail Domain Check: How to Verify Email Domain Health
In today’s digital age, email communication plays a crucial role in our personal and professional lives. However, with the ever-present threat of phishing attacks, spam, and other email-related security issues, it’s essential to ensure the safety and authenticity of your emails. This post will show you how to check email domains and prevent yourself from fraud and scams.
Why is mail domain check important?
- Prevent email spoofing. With a mail domain check, you can minimize the chances of email spoofing, where malicious parties impersonate a brand’s domain to send fraudulent emails.
- Protect against phishing. You can verify the source of an email, reducing the risk of falling victim to phishing attacks. Legitimate senders will have proper email domain configurations.
- Enhance email deliverability. If you’re the email domain owner, keeping proper SPF and DMARC records increases the chances of your emails reaching the recipient’s inbox, rather than getting flagged as spam.
- Maintain a good reputation. A well-maintained email domain helps build a positive email reputation, which is crucial for reliable email communications.
How to check mail domain health?
Performing a mail domain check is relatively easy. There are various online tools and services available that can help you check the health and configuration of your email domain.
— Extract email domain
The domain is the part of the email address that comes after the @ symbol. For example, the domain for example@gmail.com is gmail.com. However, sometimes you need to remove additional characters to find the primary domain. In the example, example@subdomain.example.com, the primary domain lies in example.com.
— Check email address
If you receive doubtful emails from brands (such as Amazon or USPS) and you suspect that someone is impersonating them, your go-to choice is to perform a reverse email lookup.
Simply type an email address into the search bar and tap Enter. BeenVerified looks at multiple databases to find potential sender’s name and identity matches and may even pinpoint the sender’s location.
What may you know about the email sender?
- Real name and age
- Address history and property information
- Contact information
- Social media profiles
- Education, job and employer info
- Possible relatives and associates
- Criminal and traffic records
If you find the email sender has no corresponding background with such brands, you’d better be careful before making financial decisions.

— Monitor mail domain reputation
Google provides a free tool named Postmaster Tools that will directly illustrate your domain reputation based on the engine’s standard. But note that it only applies to Gmail.
Generally, it shows data about SPF/DKIM/DMARC failures, spam complaints, IP reputation, encryption success rate, and more. Simply follow the Google instructions to add your domain to Postmaster Tools and verify your domain.
