Terms of Service
Last updated 30 October 2026
Conditions for using ZBounce verification and campaign services, including sender responsibilities and service limitations.
1. Operator and scope
ZBounce provides email verification, campaign tools and related software. These Terms apply when accepted in connection with registration, an order or access to the service. You must have legal capacity and authority to act for any organisation you represent.
Verification may use a purchased API key; campaign workspaces require an account and applicable sending setup. Keep credentials, keys and private payment links secure, manage authorised users and promptly report suspected misuse.
Website information is informational and does not constitute a public offer. Purchases and service commitments are formed through the applicable ordering and confirmation process. This does not remove information or rights that the law makes binding.
The License Agreement governs permission to use ZBounce software and materials; these Terms govern service use and purchases. An expressly agreed order or separate written agreement takes priority on the matters it specifically addresses. Applicable data-processing terms govern their subject matter. The Privacy Policy explains data handling and is not a waiver of statutory rights.
2. Permission to process and send
Submit only data and content you may lawfully use. Keep evidence of consent or another permitted basis, identify the sender accurately, provide required contact and postal details, and honour objections. Verification does not prove consent, ownership or permission to email. Do not use purchased, scraped or third-party lists without demonstrable lawful permission; permission-based sending is a service requirement even where local law is less restrictive.
Do not send spam, phishing, malware, deceptive messages, unlawful content, threats or harassment, or circumvent quotas, security or suppression. You retain ownership of your content and permit ZBounce to process, transmit and store it only as needed to provide the service and meet lawful obligations.
3. Regional email requirements
United Kingdom and EU/EEA: use a lawful basis under the applicable data-protection regime, including the UK GDPR and Data Protection Act or EU GDPR, and follow applicable electronic-marketing rules, including UK PECR. Provide required privacy information, obtain permission where required and respect objections. A data-processing agreement may also be required.
Canada: follow CASL requirements on consent or another permitted basis, sender identification, contact details and accessible unsubscribe options. Keep evidence of permission and honour requests within applicable legal timeframes.
United States: follow CAN-SPAM requirements on accurate sender information and subjects, required advertising disclosures, postal contact details and clear opt-out options. Respect requests and applicable legal timeframes. Using a provider does not remove the parties’ legal responsibility.
4. Unsubscribe and suppression
Do not remove or obscure unsubscribe controls. Apply a request across all marketing by the relevant sender, including other lists and API keys; do not reimport or switch keys to bypass it. An opt-out does not prohibit a genuinely necessary transactional message where law permits it.
Unsubscribe controls record the recipient’s choice within the relevant sending service. Senders must apply that choice across their marketing lists and connected keys and provide a working way to opt out for as long as applicable law requires. If a link is unavailable or messages continue, contact the sender or ZBounce support. Service features do not replace either party’s legal duties.
5. Prices, credits and cancellation
Review the price, credit quantity, taxes, expiry and any recurring billing terms shown before checkout. Agreed plan terms govern your purchase; do not assume credits roll over or never expire. Request billing assistance or cancellation through support. Mandatory consumer cancellation, refund and statutory remedies remain available; no blanket “all purchases final” term overrides them.
6. Results and availability
Verification reflects conditions at the time of the check. Remote-server behaviour, temporary errors and catch-all domains can make results uncertain. Results do not guarantee delivery, inbox placement, future mailbox availability or permission to send. Email opens may be generated by automated systems.
Except for express commitments and mandatory legal standards, the service is provided as available, without additional warranties of uninterrupted operation, complete accuracy, compatibility or fitness for a particular purpose. Keep appropriate copies of your data and assess whether the product meets your needs. A service-level or recovery commitment applies only if separately agreed. These provisions do not remove obligations to exercise reasonable care and skill where the law requires them.
7. Liability limits
Nothing in these Terms or the License Agreement excludes or limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot lawfully be excluded or limited. Mandatory consumer remedies and rights under applicable data-protection law remain unaffected.
For business customers, and subject to those exceptions and any applicable requirement of reasonableness, ZBounce is not liable for loss of profits, revenue, business, contracts, anticipated savings, opportunities or goodwill; loss, corruption or restoration of data; or indirect or consequential loss arising from use, non-use or inability to use the product or service. The listed business losses are excluded whether direct or indirect, to the extent the law permits.
Subject to the same exceptions and legal requirements, ZBounce’s total aggregate liability to a business customer arising from the affected product or service is limited to the fees paid or payable by that customer under the order for that product or service. This is a combined limit across these Terms and the License Agreement, not a separate limit under each. It applies to claims in contract, tort including negligence, breach of statutory duty or otherwise.
The business exclusions and cap do not apply to consumers. For consumers, ZBounce remains responsible for loss or damage that is a foreseeable result of its breach of contract or failure to use reasonable care and skill, and for any other liability required by law. No clause removes statutory rights to an appropriate remedy, including repair, repeat performance, a price reduction or refund where applicable.
8. Suspension, termination and changes
ZBounce may restrict or suspend access to address misuse, a material breach, nonpayment, security risks or legal requirements. Where reasonably practicable and lawful, we will explain the reason and allow a reasonable opportunity to remedy a remediable breach. Immediate action may be necessary to protect the service or others.
You may stop using the service and request account closure or subscription cancellation through support. Ending access does not by itself erase records, reverse charges already incurred or cancel commitments under an agreed order. Export, deletion, prepaid balances and refunds are handled under the applicable agreement, the Privacy Policy and mandatory law.
Material changes will be communicated as required, with notice appropriate to their effect. Changes do not retrospectively remove accrued rights or override an existing order without a valid contractual or legal basis.
9. Governing law and interpretation
These Terms, the License Agreement and related non-contractual obligations are governed by the law of England and Wales. For business customers, the courts of England and Wales have exclusive jurisdiction over related disputes.
Consumers retain the protection of mandatory laws applicable in their country of habitual residence and any right to bring proceedings before their local courts. Nothing prevents a complaint to a competent regulator or limits rights of individuals who are not parties to these agreements.
The English text is the primary version. Translations assist understanding; the English version prevails in a discrepancy only to the extent permitted by law, without overriding mandatory language requirements, consumer protections or binding information provided at purchase.
If a provision is unenforceable, the remaining provisions continue so far as legally possible.
Contact and requests
Use this address for privacy requests, billing questions or abuse reports. Include only what is necessary to identify the request; never send your password, API key or payment confirmation link.
