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.
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.
after adding this to Cloudflare, waiting some days… i still cant verify my subdomain cname.
I have an free Cloudflare plan. Is cname for sub domain possible? Maybe this is the problem?
