I initially configured my domain's (https://roblaxmod.com/) email with Zoho Mail while using Cloudflare to manage my DNS records (MX, SPF, etc.). All services were working correctly.

Recently, I have removed my site from Cloudflare and switched my domain's nameservers back to the default ones provided by my web hosting company.

My questions are:

Will my Zoho Mail setup continue to work automatically after this nameserver change, or are the required DNS records lost since they were configured in Cloudflare?

What is the best way to check and verify if my email is still being delivered correctly to my Zoho Mail inbox?

If it is not working, what steps do I need to take to reconfigure the necessary Zoho Mail DNS records with my current hosting provider?
