The .su top-level domain was originally delegated to the Soviet Union. However, even when the USSR was dissolved in 1991, the top-level domain remained. Unlike the majority of abandoned country-code top-level domains (ccTLDs), .su is managed by the Russian Institute for Public Networks (RIPN). Now, .su is actively a functional domain, and end users or organizations are able to register domain names with the .su extension. It boasts a dedicated though specialized set of users who use it symbolically, historically, or ideologically. If you also have the .su domain name, then you can easily register your .su email address for business communication through email. Let’s understand how you can create your .su email address. 

Create a .su email address if you have a domain name. 

To get a custom .su email address, you need two things: a registered .su domain name and a suitable email hosting service provider. Since you have the .su domain name, you need an email hosting service provider. If you want to establish your online presence with email and web hosting at cost-effective prices, Neo is a suitable option.

Step 1. Click on Get Started.

Go to Neo, and click on Get Started.

Step 3. Enter your desired domain name.

Whether you want the domain name to be your brand name (for businesses) or based on your profession or your name (for freelancers), enter your desired domain name and see if it is available. Remember, as per your subscription plan’s term (annual or monthly), you will have to pay the domain name’s renewal fee. 

Step 4. Sign up with Neo. 

Enter your name, personal email address, and a password to create your account with Neo. 

Step 5. Set up your custom email address. 

Now, you can set up your custom email address for your admin account, like admin@cybercore.co.site. Create your other member’s email address, set up email aliases and a catch-all account, and finalize the other settings. 

Then, you can start building your online presence with Neo’s features, like email campaign, signature designer, AI website builder, email templates, email tracking, and others. It has different features to simplify email management as well, like priority inbox, flexible storage, Smart Write, and email rules. You can download the Neo app to check your emails from your phone, whether Android or iOS. 

Concerns with the .su Domain Name

There are no strict eligibility rules or procedures to register for the .su domain name. However, there are some risks associated with this domain extension. 

The .su domain has a higher-than-average association with cybercrime, phishing, and malware distribution. Due to lenient registration policies and a lack of enforcement, it's been exploited for illicit activities.

That’s why some cybersecurity firms flag .su domains or block them by default in email or browser filters. Also, many internet users are unfamiliar with .su, which may lead to skepticism or distrust. Besides, the ICANN has notified the operator about the .su extension that it plans to retire the domain name by 2030. 

In March 2025, the operator Russian Institute for Development of Public Networks, received the planned phase-out of the domain name from ICANN. So, even if the .su domain is active today, but it is long-term usage cannot be guaranteed.
