Hard Limits & Overages
To protect against unexpected bills, API requests are blocked with a 429 status code the moment your plan reaches 100% capacity. We do not automatically charge overages. You must upgrade to the next tier to resume service in the same billing cycle.
Frequently Asked
Is a credit card required for the trial? expand_more
Yes. To prevent abuse of our API and ensure service quality, we require a valid credit card to start the 7-day free trial. You can cancel at any time before the trial ends and you won't be charged.
What counts as one call? expand_more
One successful POST /v1/check request counts as one call. Malformed requests or 4xx/5xx errors returned by our API do not count against your limit. See our API Reference for details.
Do retries count against my limit? expand_more
Yes, if the retry results in a successful 200 OK response. We recommend implementing caching on your side for emails you've already checked.
What data is stored? expand_more
We process the full email address in memory to extract the domain, but we only store the domain name for our analytics and caching. We do not persist the full email address. For complete details, read our Privacy Policy.
Upgrade, Downgrade & Cancellation expand_more
You can change or cancel your plan at any time. Upgrades are prorated immediately. Downgrades take effect at the start of your next billing cycle. Cancellations stop the next renewal, but you retain access until the end of your current cycle.
What is the SLA and support policy? expand_more
We target 99.9% uptime, but formal SLAs are only available on Enterprise/Custom plans. Support responsiveness depends on your tier (Community, Standard Email, or Priority).
