Terms of Service

KillBounce verifies email addresses you provide. We don't send mail on your behalf. We don't store your lists past the retention window in our Privacy Policy.

You're responsible for the security of your account credentials and API keys. Don't share them. If your key is compromised, rotate it from your dashboard immediately.

One person, one account — except for team and agency plans where multi-seat is the whole point.

You may not use KillBounce to:

• Verify lists you don't have permission to email (e.g. scraped/purchased lists used for unsolicited mail).
• Probe addresses to enumerate users for phishing or credential stuffing.
• Reverse-engineer the service, attempt to overload our infrastructure, or evade rate limits.

If we detect misuse, we'll suspend the account and refund any unused credits.

Credits are pay-as-you-go and don't expire. One credit = one verification, regardless of result. Charges are processed by our payment processor (Stripe). Refunds within 30 days on unused balances, no questions asked.

Accuracy guarantee: if a verification is demonstrably wrong (a deliverable address marked undeliverable, or vice versa), we refund the credit on request.

Business plans include a 99.99% uptime SLA. Below that threshold, prorated credits are issued for the affected period. Status is tracked at /status.

You can cancel any time from your dashboard. Unused credits remain redeemable for 12 months after cancellation, or refundable on request.

We can terminate accounts that violate Section 3 (Acceptable use) or remain in payment default after 30 days' notice.

To the maximum extent permitted by law, our total liability for any claim related to the service is capped at the amount you paid us in the 12 months preceding the claim. We are not liable for indirect or consequential damages.

These terms are governed by the laws of Delaware, USA. Disputes are resolved in Delaware courts unless local consumer-protection law gives you the right to a different forum.

If we change material terms, we'll email account holders 30 days before they take effect. Continued use after the effective date counts as acceptance.
