Why I need the www

I’m not very bright, but I’ve created several websites in my life. I’ve never needed to type www to view my website. Now I have a website in Kajabi and I’m using cloudflare and I need the www. Can anyone help me so I don’t need the www?

Thanks

That’s up to Kajabi. They probably use CNAMEs for this, which limits your options, but you can certainly redirect any request without the www to the www URL.
