Verify a Domain (Bulk)
Upload a CSV containing domains in column A. We'll then verify and classify them into various categories.
Est run time: 15-100s, depending on rows.
Usefulness: Will respond with one of these cats - Active Domain, Dead Domain, Free Mailbox Domain, School Domain, Not a Domain, and Cannot Determine.
Caveats: This verifies the domain, so if you input a long URL it would attempt to validate just the basic domain.
Bot Blocking: Some sites - especially Cloudflare users - may block or throttle our bots. If so, the numbers will be empty or wonky.
