What this is
EMCHEQ verifies email addresses - in real time, in bulk, and through an API - and checks the mail-security posture (SPF, DKIM, DMARC) of the domains you send from, including phishing-simulation testing. One account covers both, instead of a separate vendor relationship for each.
Who it's built for
Most of this category is priced and built for enterprise procurement: compliance paperwork, account managers, contracts sized for six-figure sending volume. If that's genuinely what you need, a larger, longer-established platform is probably the right call, and we say so plainly on our comparison pages rather than pretending otherwise.
This is built for the small team or solo developer who needs the same real checks - not a smaller, worse version of them - without the enterprise sales process. A free tier generous enough to test on your own real data, an API you can call directly, and a dashboard that doesn't assume you have a dedicated deliverability team.
How results are reported
Every verification result shows the checks behind it - syntax, domain, mail servers, disposable provider, role account - not just a score. When a result can't be confirmed (a catch-all domain, a server that won't answer), it's reported as Unknown or Probably valid, not quietly resolved into a confident-looking answer. That's a product decision, not a marketing line: see what it costs us in pricing, where we say the same thing about every competitor's accuracy claims, including our own.
