What ZeroBounce is known for
ZeroBounce is positioned as an all-in-one email deliverability platform: verification plus scoring, spam-trap and abuse detection, and enterprise compliance certifications (the kind of SOC 2 / HIPAA / GDPR paperwork that matters if procurement requires it). They publish a specific accuracy percentage, as does every vendor in this category - and every vendor's number is independently measured differently, so we're not going to repeat a number here and ask you to trust it over theirs. Compare published numbers yourself and weigh who ran the test.
Where EMCHEQ is actually different
- We say Unknown when we mean it. A catch-all domain or a server that won't confirm a mailbox gets reported as Unknown or Probably valid, with the reason shown - not folded into a confident-looking score.
- You see the evidence, not just a verdict. Every result shows which checks ran and what each one returned: syntax, domain, mail servers, disposable provider, role account.
- Mail security is in the same account. DMARC/SPF/DKIM posture checks and phishing simulation live alongside verification, not as a separate product or vendor relationship.
- The free tier is for testing, not a teaser. 100 verifications a month, no card, enough to run your own real, weird edge cases before anything costs money.
Where we don't win - said plainly
If you need SOC 2/HIPAA-level compliance paperwork for a procurement process, a decade-long public track record, or enterprise-scale infrastructure already proven at very high volume, that's a real reason to pick an established platform over a newer one. We're not going to pretend otherwise to win a comparison page.
The actual way to decide
Run the same list through both. Not a sample file - your own list, with your own catch-all domains and your own disposable-address edge cases. Whichever one's results you'd actually be comfortable explaining to your boss is the one that's earned the trust, not the one with the bigger claimed percentage.
