Terms of Service
Last updated: 15 August 2026
These terms are a contract between you and the operator of SkipBounce. They are written to be readable. Where a plain-language summary appears in italics, the full clause governs.
1. Agreement
SkipBounce (“the Service”) is provided by Werunads Agency SRL, [Registered address — fill in], Romania (“we”, “us”). By creating an account, using the API, or using the free checker on our website, you (“you”, “the Customer”) agree to these Terms and to our Privacy Policy. If you use the Service on behalf of an organisation, you confirm you have authority to bind that organisation.
2. The service
SkipBounce checks whether email addresses are likely to accept mail. It performs syntax analysis, DNS lookups, list-based checks (disposable domains, role accounts, blacklists) and an SMTP-level mailbox check, and returns a status of deliverable, undeliverable, risky or unknown with a score. It also offers bulk processing, a REST API, free DNS lookup tools, and an integration with Klaviyo.
In plain terms: we tell you, as honestly as the receiving mail server allows, whether an address will work.
3. Accounts
- You must provide accurate information and keep your login credentials and API keys confidential.
- You are responsible for all activity under your account and API keys. Tell us immediately if you suspect misuse.
- You must be at least 16 years old and using the Service for business purposes.
- One person or organisation may not create multiple free accounts to circumvent the free-plan allowance.
4. Plans, quotas and billing
4.1 Plans
Current plans and prices are shown on our pricing page. The free plan includes a one-time allowance of validations. Paid plans include a monthly allowance that resets on the first day of each calendar month and does not roll over.
4.2 What counts
Every unique address checked counts once against your allowance, whether submitted through the dashboard, bulk upload, API or Klaviyo integration. Duplicates within one bulk job are removed before counting. Checks that fail because our service is unavailable are refunded to your allowance.
4.3 Payment
- Paid plans are billed monthly in advance, in euros, through Stripe. VAT is added where applicable.
- Subscriptions renew automatically until cancelled. Cancel any time from the billing portal; you keep access until the end of the paid period.
- Upgrades take effect immediately; the difference is prorated by Stripe.
- If a payment fails and is not resolved within 14 days, we may downgrade the account to the free plan.
4.4 Refunds
Fees are non-refundable except where required by law. If something went wrong on our side, contact us — we are reasonable.
4.5 Price changes
We may change prices with at least 30 days' notice by email. Changes apply from your next billing period.
5. Acceptable use
You agree not to use the Service to:
- validate addresses you have no lawful basis to process, or lists you obtained by scraping, purchasing without consent, or otherwise unlawfully;
- send spam or unsolicited email, or facilitate others doing so;
- harvest, guess or enumerate email addresses (for example, by validating dictionary-generated addresses at a domain);
- attack, probe or overload any mail server or third-party system, or circumvent our rate limits and quotas;
- resell the Service or provide it to third parties as your own, without our written agreement;
- reverse-engineer the Service, or use it to build a competing validation product;
- violate any applicable law, including anti-spam and data-protection laws (GDPR, CAN-SPAM, ePrivacy).
Why this matters: validation traffic that looks like a dictionary attack gets everyone's IPs blacklisted. We enforce this section to protect all customers.
We may suspend accounts that breach this section, with notice where practical.
6. Your data and your responsibilities
- You retain all rights to the email addresses and lists you submit (“Customer Data”).
- You are the controller of Customer Data and warrant that you have a lawful basis to process it and to have us process it on your behalf.
- You are responsible for how you act on results — for example, for confirming a suppression in Klaviyo before it runs.
- Bulk job results are deleted automatically 48 hours after completion. Export anything you need before then.
7. Validation results
Email validation is inherently probabilistic. Results reflect the response of the receiving mail server at the moment of the check, and some servers deliberately give ambiguous answers (catch-all configurations, greylisting). We report those honestly as risky or unknown rather than guessing.
We do not guarantee that a “deliverable” address will accept a specific message, that an “undeliverable” address will never accept mail, or any particular bounce rate, inbox placement or cost saving. Savings shown in the Klaviyo integration are estimates based on the plan price you enter.
8. API access
- API access is included in paid plans and subject to the rate limits described in the API documentation.
- API keys are personal to your account. Do not embed them in client-side code or share them.
- We may change the API with reasonable notice; we will not remove documented v1 endpoints without at least 90 days' notice.
9. Klaviyo integration
- You provide a Klaviyo Private API Key and authorise us to read lists, segments and profile emails, and — only when you explicitly confirm — to suppress profiles or set custom properties on them.
- Klaviyo is a third-party service governed by its own terms. We are not responsible for Klaviyo's availability, pricing or behaviour.
- Suppression is a significant action. Always review the confirmation dialog. We are not liable for suppressions you confirm.
- You may disconnect at any time; we delete the stored key immediately.
10. Data processing terms (GDPR article 28)
To the extent we process personal data in Customer Data on your behalf, the following terms apply and form our data processing agreement:
- Roles. You are the controller; we are the processor. Subject matter: email address validation. Duration: the term of your account. Nature and purpose: checking deliverability of addresses you submit. Data subjects: your contacts. Categories of data: email addresses and derived validation results.
- Instructions. We process Customer Data only on your documented instructions — submitting an address for validation is such an instruction — unless required by EU or member-state law, in which case we inform you first where lawful.
- Confidentiality. Persons authorised to process Customer Data are bound by confidentiality.
- Security. We implement the technical and organisational measures described in section 11 of our Privacy Policy, including encryption in transit, row-level access control, a stateless validation server, and automatic 48-hour deletion.
- Sub-processors. You give general authorisation to the sub-processors listed in our Privacy Policy. We will inform you of intended changes affecting Customer Data at least 14 days in advance so you may object; each sub-processor is bound by equivalent data-protection obligations.
- Data-subject requests. We assist you, taking into account the nature of processing, in responding to requests from data subjects. Given the short retention, in most cases the data will already be deleted.
- Assistance. We assist you with security, breach notification, and impact assessments to the extent relevant to our processing.
- Deletion. Validation results are deleted automatically 48 hours after job completion; on account deletion all Customer Data is deleted within 30 days unless law requires retention.
- Audit. We make available the information necessary to demonstrate compliance and, on reasonable written notice and no more than once per year, allow audits conducted by you or an auditor you mandate.
- Transfers. Transfers outside the EU/EEA rely on adequacy decisions, the EU-U.S. Data Privacy Framework or Standard Contractual Clauses, as described in our Privacy Policy.
If you require a countersigned DPA on your own template, contact us.
11. Intellectual property
The Service, including its software, design, documentation and the SkipBounce name and logo, is our property or that of our licensors. We grant you a limited, non-exclusive, non-transferable licence to use the Service in accordance with these Terms. You may use exported results freely for your own business.
12. Warranties and disclaimers
The Service is provided “as is”. To the maximum extent permitted by law we disclaim all implied warranties, including merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the Service will be uninterrupted or error-free, or that results will be accurate in every case (see section 7). We aim for high availability but the mailbox check depends on third-party mail servers we do not control.
13. Limitation of liability
To the maximum extent permitted by law: (a) we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or goodwill; and (b) our total liability arising out of or relating to the Service in any 12-month period is limited to the amount you paid us in that period, or €100 if you paid nothing.
Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud, or for any liability that cannot be excluded by law. Nothing limits your statutory rights as a consumer where consumer law applies.
14. Termination
- You may close your account at any time by emailing us; paid subscriptions can be cancelled in the billing portal.
- We may suspend or terminate accounts that breach these Terms, with notice where practical, or discontinue the Service with at least 30 days' notice (refunding any prepaid unused period).
- On termination, your access ends and your data is deleted per the Privacy Policy. Sections 7, 11, 12, 13 and 16 survive.
15. Changes to these terms
We may update these Terms. For material changes we will give at least 14 days' notice by email or in the dashboard. Continued use after the effective date means you accept the updated Terms.
16. Governing law and disputes
These Terms are governed by the laws of Romania and applicable European Union law. Disputes are subject to the courts of Romania, without prejudice to mandatory consumer-protection rules of your country of residence. EU consumers may also use the European Online Dispute Resolution platform.
