What Subdomains To Use For Different Types Of Email

What Subdomains To Use For Different Types Of Email

All businesses today recognize what a powerful tool email is for their marketing efforts, and for boosting the value of their product or service. 

From promotional emails to transactional emails, confirmation emails, a weekly newsletter for your email subscribers, and more—email is essential for both building important relationships with new customers and for building lasting relationships with existing customers. 

For a quick intro and insight into transactional emails, watch the following video by RedFork Marketing.

Now, while it may be a bit old-school (email has been around for about 50 years, and there are 1000s of email providers), email is an essential part of business that will help you to reach your target audience and boost sales.

Email subdomains are vital to getting your email marketing and customer retention campaigns to land into your customers’ inboxes where they belong. 

Otherwise, there is a very high chance that they'll be spammed by overzealous detection tools, seriously lowering views, clicks, customer loyalty, and marketing strategy effectiveness. 

However, choosing the right subdomain to send messages from, whether using email automation for your email marketing or not, is also an essential part of the game.

What are email subdomains?

Hold on, let’s not get ahead of ourselves! Before we begin talking about subdomains, we should get down to the basics of understanding domains.

Every email address, whether from a free email service, iCloud mail, Yahoo mail, Gmail, or another email provider, contains a sender username and a sender domain. 

For the sake of this post, we’ll be using our lovely made-up company “Blumiblum,” a cat dating app for cats of all kinds.

We met on Blumiblum ...

Blumiblum operator’s email address is bluma@blumiblum.com (Bluma is my beautiful tricolor cat), the username is “bluma” and the domain is “blumiblum.com”.

Domains are the unique, human-readable identifiers of services on the internet such as websites, FTP servers, email services, API endpoints, and many more. 

Domains are frequently referred to as “root domains” or “parent domains,” which are titles given to them because they can be accompanied by subdomains (often referred to as “child domains”), indicating that they are a subsection of a larger domain (the parent). 

For example: bluma@blumiblum.com can have its very own “child”: bluma@marketing.blumiblum.com.

Why use an email subdomain?

Nowadays, email reputation is EVERYTHING! What is an email reputation, you ask? Well, it is essentially a score assigned to your organization (or domain) by the internet and email service providers after calculating different metrics.

These include metrics that can be built up through all parts of your sales funnel via targeted email campaigns, email strategy, and professional transactional emails like announcement emails, milestone emails, welcome email, and more. 

They include metrics such as sending volume over time, complaint rates, new subscribers, bounce rates, spam trap hits, message filtration rates, and more. The higher the reputation, the more likely it will be that your email will be delivered. So, what does that have to do with subdomains, exactly? 

Sender reputation is directly connected to the domain you are sending your email from. 

If you’re sending your weekly newsletter from one subdomain and those email subscribers who don’t remember signing up to your newsletter mark them as spam, this shouldn’t affect the sender reputation for the subdomain from which you’re sending promotional emails and transactional emails.

Which email subdomains should I use to send different types of email

You have now reached the fun examples part, yippee!

With so many different types of emails, including promotional emails, marketing emails, transactional emails, and valuable content for your email subscribers, you may be wondering which subdomain to use for which type of email.

Remember, choosing subdomain names for different types of emails is your job, so choose wisely! 

We recommend going for a safe and clear subdomain name that reflects the different types of emails’ goals, making it easy for your customers to recognize the purpose of your email.

1. Email newsletters

Newsletters are a vital part of any email marketing and content marketing strategy. 

They are a great way for businesses to share relevant content to establish and maintain a continuous relationship with their customers, keeping them updated via their email accounts.

Some examples of subdomains that work well for Blumiblum’s newsletter are: newsletter.blumiblum.com, news.blumiblum.com or, if you’re a real cool cat: extra-extra.blumiblum.com.

2. Automated/triggered emails

Automated emails are carefully planned messages businesses send to customers at scheduled times or in direct response to actions made on their website or web app. 

Some examples of automated emails are promotional emails, welcome emails, milestone emails, emails for new subscribers, confirmation emails, anniversary email, review request email, mid-trial reminders, and billing issues alerts.

Here are some subdomains that work well for automated emails from Blumiblum: alerts.blumiblum.com, notice.blumiblum.com, or notifications.blumiblum.com.

3. Billing emails

It’s true, billing emails are also automated emails. However, they get a subdomain of their own since they are related to what some believe is the most important aspect of a business—money.

Emails such as payment collection, late payment alerts, and credit card updates should get their own assigned domain. 

For example: billing.blumiblum.com and accounting.blumiblum.com.

4. Sales emails

Businesses utilize sales and promotional emails and email campaigns to introduce and promote products or services to customers. This is a popular approach when it comes to increasing revenue, attracting new customers, and strengthening relations with existing customers.

A subdomain for sales emails from Blumiblum’s may be: promote.blumiblum.com.

Another effective method is to use the geo (eu, us for example) or hq (for headquarters), if your business is broken down into geographic regions, to show customers that your email is specific to people such as them. Well, people from the same continent anyways! 

In any case, it’s a bit more personal and it’s a completely different subdomain to use. For example: eu.blumiblum.com.

5. Support emails

Every business needs a support team, and every support team uses emails to assist their customers. Let's face it: no product or service is entirely perfect. 

When sending a support email, you want your customers to recognize that the purpose of the email is to provide them with a solution to their problem even before opening the email. 

This is why your support team should have its own subdomain, preferably something like: support.blumiblum.com or hello.blumiblum.com to highlight their friendly and welcoming nature.

6. Day to day emails (to suppliers, customers)

We covered email newsletters, automated emails, billing emails, sales emails, review request email, welcome email, announcement email, and support emails, but what about your day-to-day correspondence with customers, suppliers, and even your boss? 

You want to avoid sending your suppliers an email from a newsletter.blumiblum.com address since they are not likely to open it. 

For this case, we recommend using a simple one like mail.blumiblum.com or not using a subdomain at all, but instead using your primary domain (i.e. blumiblum.com).

Frequently asked questions

What are the different types of email and why is it important to use different subdomains for them?

Different types of email include newsletters, automated/triggered emails, billing emails, sales emails, support emails, and day-to-day emails. Using different subdomains for each type helps maintain your sender reputation, as issues with one type (like newsletters marked as spam) won't affect the deliverability of others (like billing notifications).

How can I choose the right subdomains for different types of email?

The subdomain should reflect the purpose of the email. For example, newsletters could be sent from "newsletter.yourdomain.com", billing emails from "billing.yourdomain.com", and support emails from "support.yourdomain.com". This helps recipients recognize the purpose of your email and can improve open rates.

Why are there different types of emails?

Different types of emails serve different purposes and help to engage with your audience in various ways. For example, welcome emails help onboard new users, offer emails drive sales, and newsletter emails keep your audience informed. Using a variety of email types allows you to provide value to your audience, build relationships, and achieve different business goals.

How do I choose the right type of email to send?

The type of email you should send depends on your goal for the email and where your audience is in their customer journey. For example, welcome emails are appropriate for new subscribers, while offer emails might be more suitable for customers who have shown interest in your products or services.

Understanding your audience and their needs can help you choose the most effective type of email.

What is a transactional email?

A transactional email is a type of email that's triggered by a specific action or behavior from the user. Examples include order confirmations, password reset emails, and account notifications.

Transactional emails are important for providing users with necessary information and updates about their interactions with your service or product. They can be effectively managed using a service like Mailer To Go.
