I built checkemail.dev to prevent fake signups, disposable emails, and trial abuse — a problem most SaaS products deal with. It verifies emails instantly without sending SMTP requests, so it’s fast, reliable, and lightweight. We also don’t rely on RCPT TO checks, since most email servers don’t actually confirm whether an email exists and often return misleading responses. Instead, the system focuses on smarter validation methods that are more reliable in practice. The product is simple, works.
