Email verification checks whether an email address is real, deliverable, and safe to send to. Without it, invalid addresses pile up in your list — hurting your sender reputation, increasing bounce rates, and getting you flagged as spam. Mailtrix runs a 5-layer check (syntax, MX records, DNS, disposable detection, SMTP handshake) to give you a definitive verdict on every address.
