Email Deliverability (1) : Domain Reputation



What is Email Deliverability?

The email deliverability means that the messages originating from your domain are received at the inbox, and not considered junk or spam. Good email deliverability achieved when 95 % of the emails reached emails inbox.

Domain Reputation:

What is a domain reputation?

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

1. WHOIS record:

What is the WHOIS record?

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

What is the Domain name privacy?

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

Best Practice for WHOIS record:

The email domain must have accurate WHOIS record without domain name privacy. Which means the domain owner contact information must appear, including 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 the 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.

2. RFC 2142 email :

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

postmater@yourdomain.com used for general issues.

abuse@yourdomain.com used for reporting spam or abusive email that may originate from your domain.

hostmaster@yourdomain.com used for domain registration issues.
RBLs (Realtime 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.

3. Use a reputable domain name service:

Sending emails depends on the Domain Name Service (DNS). So the existence of 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 which the domain registrar commercial DNS or you configure by yourself in the domain name management console.

4. 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.

5. You website does not contain a virus or malware.

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.
