How can we use subdomains when thinking of your email optimization strategies? Every email address has two main parts: the sender’s username and the sender’s domain. For instance, in the email address katie@lancinglight.com, “katie” represents the username, and “lancinglight.com” is the domain. A subdomain acts like an additional piece of your main domain, added at the beginning. Think of it this way: katie@subdomain.lancinglight.com.

Now, here’s where it gets interesting. While a subdomain is linked to your main domain, it possesses its own unique IP address. Consequently, Internet Service Providers (ISPs) and mailing servers treat your subdomain differently than your main domain. This distinction can be quite advantageous.

Why Should You Use an Email Subdomain?

Email providers such as Google and Outlook keep a close watch on your sending domains, linking a sender’s reputation to each one. If your emails are frequently marked as spam or show low engagement, it can negatively affect your sender reputation.

A poor sender reputation leads to email deliverability issues, with ISPs possibly rejecting most of your emails due to reputation standards.

Improving the reputation of your main domain is tough, and changing it might not be possible because it’s often the recognizable business name. Managing your email reputation becomes simpler with a subdomain. A subdomain with a bad reputation can be switched out for another one! Using an email subdomain shields your main domain from reputation issues, ensuring that emails are sent from a subdomain trusted by email providers.

While it’s not necessary to use multiple subdomains, having at least one email subdomain is crucial to protect your root domain’s reputation.

These are some ideas behind having a subdomain for email delivery:

Partnership and Public Relations emails play a crucial role in building partnerships and fostering relationships with other brands or influencers. These emails often have different engagement metrics compared to operational emails. Subdomains provide an effective solution to maintain a positive reputation for partnership and public relations emails. By segregating these emails onto a separate subdomain, you can prevent any potential negative impact on the reputation of other types of emails sent from your main domain. Additionally, having a dedicated subdomain for partnership and public relations allows for customized tracking and analysis, enabling you to measure the effectiveness of your outreach efforts and make necessary adjustments to improve engagement and response rates.

Promotional emails are a crucial part of any marketing campaign, but they can be a double-edged sword. Subscribers may mark promotional emails as spam if they receive them too frequently or if the content isn’t relevant to their interests. By utilizing a separate subdomain for promotional emails, you create a distinct identity for these messages. This ensures that any potential negative reputation associated with promotional emails doesn’t affect the delivery of other types of emails sent from your root domain. Moreover, having a dedicated subdomain allows for specific monitoring and optimization of promotional email performance, enabling you to tailor your content and frequency more effectively to target audience preferences.

Operational emails, such as password resets, order confirmations, and payment receipts, are essential for providing a seamless user experience and maintaining customer trust. These emails typically have the highest engagement rates and must reach subscribers’ inboxes promptly. Utilizing a dedicated subdomain for operational emails ensures that they are prioritized and delivered efficiently, without the risk of being lost in spam folders. By separating operational emails from other types of communication, you can maintain a high sender reputation specifically for these critical messages. Moreover, having a separate subdomain for operational emails allows for specialized monitoring and optimization to ensure optimal deliverability and engagement.

Utilizing email subdomains can significantly improve your email strategy and safeguard your sender reputation. By segregating different types of emails onto separate subdomains, you protect your root domain’s reputation while ensuring important messages reach your audience.
