If you want a .eus email account you can use the ni.eus service. It is free, it is in Basque, it does not show ads and it maintains the privacy of users’ data. As in any other email service (Gmail, Outlook, etc.), you can choose the address you want if it is available.
Also, you can add your ni.eus address to your usual e-mail service to be able to use all your addresses from the same place. You have help articles if you need assistance taking that step.
In addition to the free option, you can have your addresses with a .eus domain name chosen by you, instead of having the domain ni.eus. This option is paid and there are two different plans.
On the one hand, if you choose the Premium plan you can create 3 addresses with your domain paying € 3 / month. With the Erraldoia plan you can create as many email addresses as you want, paying € 9.99 per month. The cost of registering your domain name is included in the price of both plans.
Finally, if you want to have your e-mail address with another provider, that is also an option. In that case, it is usually purchased as an additional service when registering the domain name. However, some registrars that sell .EUS domain names offer an e-mail address free of charge. In our price table you can see which registrars offer free e-mail addresses and how many addresses they allow you to create. Depending on the number of addresses you need, you can register your domain name with one of these registrars so that you don’t have to pay for email accounts.
If this is not enough, you can sign up for more email accounts with any registrar in the table when you register your domain name.
