Terms of Service

Effective date: 2026-08-01 Last updated: 2026-07-13

These Terms of Service ("Terms") govern access to and use of the skink email verification API and dashboard (the "Service"), operated by Sagar Parmar, an individual resident of India, trading as "skink" ("we," "us"). skink is not a registered company — you are contracting with an individual. By creating an account or using the Service, you ("Customer," "you") agree to these Terms. If you are entering into these Terms on behalf of an organization, you represent that you have authority to bind that organization.

1. The Service

skink provides an API and dashboard that assess the likely deliverability of email addresses submitted by Customer. skink does not send email on Customer's behalf and has no role in Customer's own sending infrastructure or practices.

2. Accounts

You must provide accurate information to create an account and are responsible for safeguarding your API keys. You must notify us promptly at `support@skink.dev` if you believe a key has been compromised; we will revoke and reissue it on request. Where an account is created with an email address and password, that account is not active — and no sign-in or credits are usable — until you confirm the email address via the link we send you.

3. Acceptable Use

Use of the Service is subject to our Acceptable Use Policy, incorporated into these Terms by reference. Without limiting that policy, you may not use the Service to facilitate spam, phishing, harassment, or any unlawful activity, or to verify addresses obtained through unlawful means (e.g., harvesting, purchasing without rights, or scraping in violation of a source site's terms).

4. Customer Warranties

You warrant that, for every email address you submit to the Service, you hold an independent lawful basis and any consents or rights necessary under applicable data-protection and anti-spam law (including GDPR, DPDP, CAN-SPAM, and CASL as applicable) to process that address, and that your use of the Service and any results it returns complies with applicable law.

5. Fees, Billing, and Credits

5.1 Prepaid credits

  • The Service is billed on a usage basis: one credit per verification, per the pricing published at skink.dev/#pricing. Credits may be purchased either as a fixed-price pack or at a pay-as-you-go rate that is quoted and charged at the time of purchase.
  • Credits do not expire, are non-transferable between accounts, and are consumed only by successful use of the Service. No charge is made for results returned as `unknown`.
  • Purchasing credits is a one-time payment. It does not create a recurring subscription or authorize any future charge; no further payment is taken until you initiate another purchase or enable auto top-up under Section 5.2.

5.2 Optional auto top-up

  • You may separately choose to enable auto top-up, which authorizes us to charge a payment method you provide (a "mandate") to repurchase a credit pack you select when your prepaid credit balance reaches zero. Auto top-up is disabled by default and is never enabled without your affirmative action. Nothing is charged when the payment method is saved.
  • Each auto top-up charge is for the full price of the pack you selected, at the same price shown in Section 5.1, and grants the corresponding credits immediately on successful payment.
  • If an auto top-up charge fails, auto top-up is switched off immediately and no further automatic charges are attempted until you re-enable it. Any remaining prepaid credit balance is unaffected and remains usable.
  • You may disable auto top-up at any time from your dashboard, and may remove the saved payment method via the billing portal. Disabling it ends future charges under this section; it does not affect credits already purchased under Section 5.1 or this section.

5.3 Payment processing and refunds

  • Payment is processed via Lemon Squeezy or Dodo Payments, our payment processors and merchants of record; skink does not store your full payment card number. An append-only usage and billing ledger is available in your dashboard.
  • Refunds are issued at our discretion or as required by applicable law. Where a purchase is refunded, we will claw back the corresponding unused credits from your account balance, limited to the credits remaining at the time of the refund; credits already consumed by verifications are not reversed.

6. Disclaimers

VERIFICATION RESULTS ARE PROBABILISTIC, NOT A GUARANTEE. A `deliverable` result does not guarantee the message will not bounce, and a `risky` or `unknown` result does not guarantee the address is undeliverable — this is inherent to email verification generally, and particularly for catch-all and security-email-gateway-protected domains, where no verifier (including skink) can determine mailbox existence with certainty. THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT, EXCEPT AS EXPRESSLY STATED IN THESE TERMS. skink is not responsible for Customer's downstream sending decisions, deliverability outcomes, or sender-reputation consequences.

7. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SKINK'S TOTAL LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE FEES PAID BY CUSTOMER TO SKINK IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM. NEITHER PARTY WILL BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES. Nothing in this section limits liability that cannot be limited under applicable law.

8. Suspension and Termination

We may suspend or terminate an account for violation of these Terms or the Acceptable Use Policy, suspected abuse, volume anomalies indicating misuse, or non-payment, with notice where practicable. You may terminate your account at any time; see our Data Retention schedule for what happens to your data on termination.

9. Confidentiality

Each party will protect the other's confidential information with the same degree of care it uses for its own confidential information of similar nature, and not less than reasonable care, and will use it only as necessary to perform under these Terms.

10. Changes to the Service and These Terms

We may update these Terms from time to time; material changes will be communicated by email or in-product notice with reasonable advance notice, and continued use of the Service after the effective date of a change constitutes acceptance.

11. Governing Law and Dispute Resolution

These Terms are governed by the laws of India, without regard to conflict-of-law principles. Subject to Section 7's limitation of liability, any dispute arising out of or relating to these Terms or the Service is subject to the exclusive jurisdiction of the courts at Surat, Gujarat, India.

12. General

  • Entire agreement. These Terms, together with the Acceptable Use Policy and the DPA, are the entire agreement between the parties regarding the Service and supersede any prior agreement or understanding on the same subject.
  • Severability. If any provision of these Terms is held unenforceable, the remaining provisions remain in full effect, and the unenforceable provision will be interpreted to best accomplish its original intent.
  • No waiver. Failure to enforce any provision is not a waiver of the right to enforce it later.
  • Assignment. You may not assign these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of substantially all our assets, with notice to you.
  • Force majeure. Neither party is liable for a failure or delay in performance caused by circumstances beyond its reasonable control, including infrastructure or internet outages beyond our direct providers' control.
  • Export compliance. You represent that you are not located in, and will not access the Service from, a country subject to a comprehensive trade embargo, and are not on any restricted or denied-party list, under applicable trade control laws.
  • Independent contractors. The parties are independent contractors. Nothing in these Terms creates a partnership, joint venture, agency, or employment relationship.
  • No third-party beneficiaries. These Terms do not confer any right or remedy on anyone other than the parties.
  • Notices. We may send notices to the email address on your account. You may send notices to `support@skink.dev`.
