Overview

TrueMail.io provides email verification services designed to help businesses maintain clean email lists and protect sender reputation. The platform performs syntax validation, domain health checks, and authentication record verification (SPF, DKIM, DMARC) to identify invalid, risky, or duplicate addresses. It supports both single email checks and bulk list processing, with a real-time API for integration into CRMs, marketing automation tools, and custom applications. By removing bad addresses before sending, users can lower bounce rates, avoid spam traps, and improve overall email deliverability.

SPF, DKIM, and DMARC verification
