Mail ist set up wanting cloudflare log ins

[skippyinspace]

Hopefully something simple, have migrated to shopify from Magento 2 and moving our mail list from mailchimp to Klavio and have changed webdevelopers,

Currently trying to ensure our mailist emails are verified which they are not but when going to verify them its asking us to log into cloudflare.

We dont have a cloudflare account but our domain supplier is showing the standard 2 nameservers for cloudflare

I know Shopify now has something to do with cloudflare so are the nameserves becouse of that, But then again how do we log in.

Where should the nameservers point
