Yes. If you want to have email hosting, then you will need to have a linked domain name. Part of what makes Titan a top solution for business owners is that it offers more than just email storage space. It also offers premium business tools that are valuable across the whole workspace. If you pay for a domain for your company, you want to ensure that no one else is using that email address. It’s also why there’s no way to create a free business email address. If you want business email addresses to match your domain name, you will need to look further afield than services like Gmail. Google workspace does allow you to create business email accounts but this is a paid service as is the custom domain that it is linked to.
