If Cloudflare or Vercel hosts your DNS, you no longer have to copy records by hand. Click Connect on the domain page and approve the access. Samva reads your zone and shows the records your domain needs to send, receive, and track. Select Add N records and it creates them.
Cloudflare shows a consent screen. Vercel asks which account or team to use. Either way you land back on the domain page.
If sign-in isn't available, create an API token with DNS read and write access, scoped to the zone if your provider allows it. Adding records yourself still works for every domain.
