We are trying to set up Sendgrid for a subdomain and are unsure where to start. We ideally want to keep the DNS for the root of the domain with Azure but the subdomain on Cloudflare.
That’s called Sub-Domain Delegation - In order to do this you need an Enterprise account at Cloudflare.
If you have one it’s totally possible, you will add Cloudflare NS records on AZURE for the SUB domain in your Cloudflare account. But without an enterprise account, you won’t be able to get it accomplished.
Thank you. I have submitted a contact me form to talk to sales, for just this feature I am afraid that the enterprise account may be prohibitively expensive, but it doesnt hurt to ask and see what else may be available.
