CloudflareAccess Verification Email is not delivered to .company domain


I was trying to sign in to my Cloudflare account using the WARP application on my mac. After I clicked the “Login to Cloudflare Zero Trust” button, I was prompted to visit the “” website. Yet, after I entered my email, I didn’t get any email in regard to the one-time pin code.

I have checked that I do not have any restrictions restricting what domain is allowed and what is not allowed to sign in.

My email domain is .company. I suspect that the email address that ends with this domain cannot receive verification emails. I used another email that ends with and I found out Cloudflare emails can reach that Gmail mailbox. I verified that my mail server was in operation and could receive emails from other email addresses. I also checked my Junk mail, no emails from Cloudflare were found.
