Hi all, I’m trying to host a newsletter on Ghost and am new to this. I’ve ChatGPT’d until I can no longer, need help please.

I registered icjoe.com with cloudflare and am using Ghost for newsletters. I want to manage auto response emails etc so i got Zapier. I need a place to host an email address “joe@icjoe.com” so I also got Zoho and set up that mailbox including adding a DNS entry at Cloudflare, after two days of mailing it it bounces back saying "DNS Error: DNS type 'mx' lookup of icjoe.com responded with code NOERROR DNS type 'mx' lookup of icjoe.com had no relevant answers. DNS type 'aaaa' lookup of icjoe.com responded with code NOERROR DNS type 'aaaa' lookup of icjoe.com had no relevant answers. DNS type 'a' lookup of icjoe.com responded with code NOERROR DNS type 'a' lookup of icjoe.com had no relevant answers. " It seems I need to add another or fix my DNS entry? I'm not sure, thank you
