Setting Up Email With Namecheap

HELP ME PLEASE. My entire operation is being held up because I cannot for the life of me get my custom email working. They are requiring one for a business bank account and I need to add it to my website, and so on and so forth.

I bought both my domain and my custom email on Namecheap, and I followed the step by step instructions to host it on Cloudflare exactly as it was laid out for me. It isn’t working at all, and nowhere at all did it say anything about allowing any time for it to take affect.

Can someone help me out please?

It’s usually this (email-related DNS records need to be set to :grey: DNS Only):
