CSVgo is a fast email verification tool built for cold emailers. It cleans lead lists, verifies catch-all emails, removes invalid addresses, and identifies Gmail, Outlook, and SMTP providers so you can increase deliverability and protect your domains.
Most verifiers take 30–45 minutes to process a list and cannot validate catch-all emails. CSVgo verifies thousands of rows in minutes and recovers 20–30 percent more usable leads while automatically grouping results by ESP for higher reply rates.
