The Fundamentals Of Email Subdomains

How to manage email subdomain custom mailboxes using SMTP/IMAP mailserver settings.

Sending an email entails more than just drafting the emails and sending them, especially if they are transactional, mass, or marketing emails, to name a few types of communications. Subdomains are an unseen but essential component of the email delivery process for businesses worldwide. And this article will teach you all you need to know about them from the ground up. Even so, we will offer you an email subdomain example when it comes to set up.

So let's get started.

Subdomain definition

A domain is a one-of-a-kind, human-readable identifier for a website. This is frequently referred to as the parent domain or root domain.

A prefix that appears before the root domain is known as a subdomain. Websites frequently utilize subdomains to redirect traffic to a new IP address while keeping users on the same parent domain. Any company by the name DataSolutions, for example, hosts the developer documentation on a different service; thus, they use documentation.DataSolutions.com as a subdomain.

Email subdomain definition

Subdomains for email are the most frequent means for professionals to send and receive emails. A @yourdomain.com domain, rather than a @gmail.com or @yahoo.com address, gives your company a far more professional appearance. Many organizations choose to send professional emails from their root domain since it allows them to verify that the email was sent from the company readily.

Why do you need to use email subdomains?

The most significant benefit you celebrate is brand reputation.

Email reputation, which is a score for how successfully consumers interact with your emails, is essential. Major email providers like Yahoo and Gmail will use your analytics to gauge your brand reputation. If Gmail notices that your emails have a high level of engagement, it's a good bet that you're following email best practices. However, if people give negative signals to Gmail, such as flagging your email as spam, that's a problem.

The reputation of your email is dependent on both domain and IP address reputation.

This is a good thing because your email marketing campaigns' reputation could affect whether or not potential consumers receive emails from your sales staff.

How To use email subdomains

The procedures of using the email subdomains might vary, but here is a generalized process you may employ. In this example, we have used Mailgun's implementation procedure.

  • Log in to the email subdomain provider site and select 'Sending' from the left-hand menu to begin sending messages.
  • In the upper right corner of your screen, click on the green 'Add New Domain' icon to get started. Please keep in mind that you must first link a credit card to your Mailgun account before you can add custom domains. If your button is greyed off, you will need to enter your credit card information before proceeding.
  • Select 'Add Domain' from the drop-down menu.
  • On the following screen, Mailgun gives you several DNS records that you can use to point your domain to Mailgun. MX Records, SPF Records, and DKIM Records are some of the record labels that have come out recently.

As soon as you've added your DNS records and Mailgun has confirmed them (which can take up to 48 hours), you may start using email for subdomain.

Best practices to optimize email subdomains performance

  • Separate your marketing emails and transactional emails using subdomains.
  • Use the specific email subdomains for emails exclusively.
  • Track your sender's statistics and analytics reports.
  • Observe your feedback loops.
  • Use a set sending schedule.

With our discussion of what an email subdomain is, why they're essential, as well as how to set up one up for an email marketing platform, you're now ready to send some emails.
