Free Verification software

An email verification tool checks whether an email address is real and safe to send to. It pings the mail server, detects invalid addresses, spam traps, and catch all domains, and tells you which addresses will bounce. Verification is the quality control step between finding an email and sending to it. This page lists only permanent free tiers, not timed trials.
