No upselling. Yes they might have something in the order process. Like when ordering a VPS you can add windows os or some control panel type software. I didn’t pay anything extra and my domains all have private whois details when lookups are done. The one thing they did offer in the order process for domain transfer was something to do with anycast DNS, but it was just a box on the page and wasn’t in your face or annoying.

No annoying emails either. I only get emails from them related to services I purchased from them which include changes to whois contacts(also usually get a email from CIRA for my .ca domains), bill PDF being ready for download, or additional IP is available and ready for use etc.
