How credits work
A credit is spent once per email check — one call to the real-time API, or one unique domain in a bulk CSV upload. Every plan includes the full feature set (real-time API, bulk CSV checks, analytics, per-team allow/deny rules); the tiers below differ only in monthly volume and cost per check — Starter works out to about $1.00 per 1,000 checks, with a lower rate at each higher tier.
Credits refresh to your plan's full allotment every billing cycle; unused credits don't carry over month to month. If your balance runs low, we email your team before you hit zero, so a signup form calling the API doesn't break without warning.
