We are using newsletter to send bulk emails.
Newsletter software need cname for sub-domain verification. We using cloudflare nameserver. So we add cname in cloudflare.
Open cloudflare and add:
cname Name: news
Proxy status: DNS ONLY (cloud is grey)
3 days later we try to add subdomain in newsletter software and start cname verification.
But failed every time.
We got this instruction but still not working:
We also testing with online cname checker:
We get correct cname result.
But our newsletter software still not find this cname.
We try second test: deactivate cloudflare and cloudflare nameserver on domain. Then we add cname. After doing this cname was found by newsletter-software. So the problem is cloudflare. Adding cname to cloudflare not working with newsletter software.
