Email Deliverability (1): Domain Reputation

What is Email Deliverability?

Email deliverability means that the messages originating from your domain are received in the inbox and not considered junk or spam. Good email deliverability was achieved when 95 % of the emails reached the email inbox. One of the favourite online tools to measure email deliverability percentage is glockapps:

What is a Domain Reputation?

Your domain reputation is measured as a score from 0 to 100. As the domain reputation score is high near 100, your domain is considered trusted, and more emails from your domain are received in emails inbox. To increase the domain reputation score, you need to use the following best practice. You need to achieve all domain best practices to increase your domain reputation score.

WHOIS record:

What is the WHOIS record? 

Whois record is a record that indicates who owns the domain and how to contact them. ICANN regulates domain name registration and ownership.

What is Domain name privacy? 

When you enable domain privacy, the domain name registrar information replaces the domain owner’s contact information. It protects the domain owner’s information from spammers and junk emails.

Best Practice for WHOIS record: 

The email domain must have an accurate WHOIS record without domain name privacy. This means the domain owner’s contact information must appear, including an updated phone number and email address, because legitimate email senders do not hide their information.

The internet reputation systems assign an excellent reputation to domain names without confidential contact information, i.e., without domain privacy. ISP’s spam traps pass domain names with the correct contact details because it is easier to investigate when spam or abuse comes from a domain.

Ensure that The emails listed in WHOIS information are valid, and regularly access emails inbox and read received emails to monitor complaints and take suitable actions to prevent blocking your domain or singing it with a bad reputation.

Check the registration and expiration date from the WHOIS information:

The best practice is that domain registration time was more than six months ago, and the domain expiry date is more than one year away. To check domain WHOIS information and blacklists, you can use famous MXTOOLBOX website supertools:

RFC 2142 email :

RFC2142 determines the standard email addresses to contact the person with a particular role inside the organization. These emails are :

  • is used for general issues.
  • is used for reporting spam or abusive email that may originate from your domain.
  • is used for domain registration issues.

RBLs (Real-time Blacklists) list domains that do not comply with RFC 2142, so be sure these standard emails exist and regularly access and read inbox messages. These emails may contain messages that indicate an early sign of a bad reputation.

Use a reputable domain name service:

Sending emails depends on the Domain Name Service (DNS). So the existence of a perfect domain name service helps to resolve email queries quickly. A delayed or inadequate DNS service decreases email deliverability due to increased failed authentication, which may cause internet reputation service to mark your domain with a low reputation.

WHOIS information lists the DNS used by your domain, maybe the “domain registrar commercial DNS” or the DNS you configure yourself in the domain name management console. 

Your domain not listed in any Realtime Blacklists:

If your domain is listed, you can ask the RBL to delist your domain, but before doing that, you need to know the reason causes blocking your domain and fix the issue, then ask them to delist your domain.

Your website does not contain a virus or malware.

How to check your domain reputation?

There are many web tools to check domain reputation :

What are Real-time Blacklists (RBLs)?

Realtime Blacklists (RBLs) are a database containing a list of all domains and IP addresses considered a spam source. Barracuda and Spamhaus are examples of RBLs. Many RBLs use spam traps to detect spam.

What are the Spam Traps?

Spam traps are hidden emails used by RBLs to determine spammers and used by ISPs and email providers (like Gmail) to determine the unwanted senders.
