I’m trying to parse exactly how I can accomplish verifying a txt record for a third party mail service. I’ve read a few posts, but it’s unclear if they apply to my situation. I have a domain purchased from BlueHost, hosted at InfinityFree, and am looking to use addy.io for a mail service. Am I right to assume that InfinityFree is the DNS here, as I am using it’s name servers to point traffic there (via BlueHost’s registration)? If so, is there really no way to add a txt record for verification?
It’s possible, but you can’t do it directly from InfinityFree’s system. Instead, you can set up Cloudflare with the custom domain you use on your InfinityFree account, and from there you can add a txt record on Cloudflare’s end. You can find a guide to setting up Cloudflare with your InfinityFree account, here.
