FAQ

Questions,
answered.

No. Credits you purchase never expire. Use them whenever you need — no time pressure, no subscription lock-in.
SMTP probing gets your IP blocked by Gmail, Yahoo, and Outlook within days. The major providers have made it effectively unusable for small operators. We skip it intentionally to protect your sender reputation and give you reliable, fast results.
90–95% for most business use cases. MX validation, disposable detection, DNSBL checks, and heuristic scoring catch the vast majority of bad addresses. The remaining uncertainty is catch-all domains — which SMTP can't reliably resolve either.
Yes — REST API access is included on every plan including free. Pass your API key via the X-API-Key header. Single and bulk endpoints both available. Full docs in the dashboard after signup.
A confidence score between 50–84. The domain resolves and accepts mail, but there are signals worth noting — catch-all detection, low-trust mail server, role-based address, or a suspicious TLD. You set your own threshold.
Yes. Remove anything invalid or disposable. For risky results, most cold emailers use a 70+ confidence cutoff. That approach reliably keeps bounce rates under 3%.
