How to confirm if domain transfer from godaddy to cloudflare is complete or not?

I transferred domain to Cloudflare from Godaddy but there is no way to check the status.
Godaddy is still sending mails to renew the domain.
So who has the domain?

And now when I browse the support there is no section for domain and there is no category in list. Hope you guys do have proper support for people who are transferring domains to you.

You can check from the Cloudflare dashboard. The Overview for that domain should show you the Registrar.

Also from Dashboard Home, clicking on “Start transferring now” should get you into the registrar system to see which domains are eligible, and which ones are already in or in process.
