Understanding Subdomains, Business Email, and Subdomain Stripping

What are Subdomains?

A Business email subdomain stripping is a prefix added to a domain name to create a separate website or web service. One such subdomain of example.com is blog.example.com. Subdomains can be used for different purposes, such as hosting a blog, a forum, an online store, or a landing page. Subdomains are part of the domain name system (DNS), which maps domain names to IP addresses.

Types of Subdomains:

There are two main types of Business Email Subdomain Stripping generic and branded. Generic subdomains use common words or abbreviations, such as www, mail, or shop. Branded subdomains use the name of the business or the product, such as Apple, Amazon, or Netflix. Generic subdomains are more common and easier to remember, but branded subdomains can help build brand awareness and trust.

Subdomain vs. Domain:

A domain is the main part of a website address, such as example.com. A domain requires registration and renewal with a domain name registrar, while a subdomain can be created and deleted by the domain owner. A domain can have its own SSL certificate, while a subdomain can share the certificate of the domain or have its own.

Business Email and Subdomain Stripping:

A business email is an email address that uses the domain name of the business, such as name@example.com. A business email can help create a professional image and increase credibility with customers and partners. However, some email services may strip the subdomain from the email address and display only the domain name, such as name@example.com instead of name@blog.example.com.

This can cause confusion and miscommunication, especially if the subdomain is important for identifying the sender or the purpose of the email. To avoid subdomain stripping, it is advisable to use a branded subdomain for business email, such as name@apple.com instead of name@www.apple.com.

Why Use Business Email Subdomain Stripping?

  • Using a domain aliasing feature that allows you to map multiple subdomains to a single domain. For example, Zoho Mail offers this option for its users.
  • Using a subdomain stripping feature that automatically removes the subdomain from the email address when routing the email back. For example, Cloudflare plans to support this option for its customers.
  • Using a custom email routing rule that redirects the emails from subdomains to the main domain. For example, you can use this method if you have your own email server or use a third-party service.

Reducing spam and phishing attacks by filtering out emails from unknown or suspicious subdomains. Enhancing brand recognition and consistency by using a single domain name across all departments and teams.

Manual vs. Automated Stripping:

Manual subdomain stripping involves manually editing the DNS records of each subdomain and redirecting them to the main domain.

Manual subdomain stripping gives more control over the process, but it can also be time-consuming and error-prone, especially if there are many subdomains to strip.

Automated subdomain stripping involves using a tool or a script that automatically detects and removes subdomains from a domain name. This can be done using a web application, a browser extension, or a command-line tool. Automated subdomain stripping saves time and effort, but it can also be less accurate and flexible, depending on the quality and functionality of the tool.
