CaptainVerify

CaptainVerify protects deliverability by validating email addresses before you send. Upload a CSV for bulk cleaning or connect the real time API and widget to verify at the point of capture. The service checks syntax, domain, MX records, and SMTP responses, and flags disposable or catch all addresses so your lists stay healthy. Clear status codes and downloadable reports make it easy for marketing and sales teams to maintain hygiene, reduce bounce rates, and protect sender reputation. If your growth relies on email, CaptainVerify is a fast, accurate layer that pays for itself by keeping more messages in the inbox. It scales with your team, includes helpful templates and examples, and keeps setup simple so you can launch fast and iterate based on results.
