Ready to buy, but have some previous questions:

1. Can I use It in Spanish language? Or any other language?
2. Can I set my custom CNAME? White-label the platform?
3. Can I set my own SMTP? Email notifications could be in Spanish too?
4. Can I create assigment templates that I can reuse it?
5. How works the user login process? I have to create users, or use magic link?

Thanks.
