Unable to use CloudFlare

Dear,
I have a small domain and hosting reseller company
My official domain is registered with reseller-club where i define nameserver and child nameserver for the hosting
When I signup Cloudflare and update Cloudflare’s namerserver in reseller-club all my clients having issue with their emails
That’s why I revert back old nameservers and then issue resolved
My official domain email is working from google workspace
How can I use Cloudflare and what will be the settings?
please help … thanks
