Actually that's a very specific company's way to add it
Most of us have cPanel, and the way to do this is go into the Zone Records:
https://www.namecheap.com/support/kn...for-my-domain/
(someone out there on the web recommended TTL at 3600)

Free tool to check to see if your host already gave you a DMARC policy, I just found out that Namecheap added one for me: https://mxtoolbox.com/DMARC.aspx

For our cold email campaigns, which send 100,000+ cold emails per acct each month, we've stopped using Namecheap.

We discovered that a lot of the domains were blacklisted before we even sent a single email, despite having the three email security protocols (DMARC, SPF, and DKIM) correctly set up.

Important to know that these were also all new domains that had not even been created before.

Now we buy our domains from GoDaddy. Although it's slightly more expensive, we experience zero headaches.
