1. Scope and customers
These Terms apply to the AI Inbx website, dashboard, APIs, email infrastructure, integrations, documentation, and related services (the “Service”). A plan description, checkout page, or individual order forms part of the contract and takes priority where it expressly conflicts with these Terms.
A “Customer” or “you” may be an individual using the Service personally or professionally, or an organization. If you use the Service for an organization, you confirm that you are authorized to act for it. References to a “Consumer” mean a natural person acting mainly outside their trade, business, or self-employed professional activity. References to a “Business Customer” mean a customer acting for such an activity or another customer that is not a consumer.
You must be at least 18 years old and legally capable of entering into this contract. You may not use the Service if applicable law prevents you from doing so.
2. Contract formation and accounts
For a free plan, a contract is formed when you expressly accept these Terms and we provision access. For a paid plan, a contract is formed when the checkout process confirms the order or we accept an individual order. Product and pricing pages are invitations to place an order unless they expressly say otherwise.
We may use a third-party merchant of record to complete paid orders. Where checkout identifies Sold through Link, LLC or another Stripe affiliate as merchant of record, it collects payment and handles the transaction, indirect taxes, transaction support, and refunds on our behalf under the terms shown at checkout. AI Inbx remains the provider and seller of the Service.
Account information must be accurate and current. Accounts are personal to the named user and may not be shared. You are responsible for your users, API keys, connected mailbox credentials, and activity in your workspaces. Report suspected compromise promptly to me@paukraft.com.
3. Service and permitted use
AI Inbx provides programmable email sending, receipt, threading, categorization, scheduling, pacing, suppression, webhooks, and mailbox connections. Functionality, quotas, regions, and support depend on the selected plan or order.
We may maintain and improve the Service. For a paid Service supplied continuously, we will not materially reduce purchased core functionality during the current billing period except where needed for security, legal compliance, or circumstances outside our reasonable control. Section 15 contains additional rules for changes affecting Consumers.
Beta, preview, sandbox, and free features may be changed or discontinued on reasonable notice where practical. Unless an order states otherwise, no uninterrupted availability or specific delivery time is guaranteed. Email delivery also depends on recipients, networks, DNS, mailbox providers, reputation, and systems outside our control. Mandatory statutory rights remain unaffected.
4. Customer responsibilities and acceptable use
You must:
- use the Service lawfully and comply with applicable data protection, ePrivacy, anti-spam, competition, consumer-protection, intellectual-property, export-control, and sanctions laws;
- have any legal basis required for recipients and messages, provide required notices, honor objections and opt-outs, and retain evidence of consent where consent is required;
- configure sender identities, authentication, tracking, retention, webhooks, and connected mailboxes appropriately; and
- ensure your instructions and Customer Content do not cause AI Inbx to violate law or third-party rights.
You may not use the Service for unlawful unsolicited messages, phishing, fraud, malware, harassment, credential theft, deceptive impersonation, illegal content, or attempts to disrupt, probe, reverse engineer, overload, or bypass the Service's security or limits.
We may apply reasonable volume, rate, reputation, and abuse controls. Suppression controls must not be bypassed. You will reasonably cooperate with abuse, deliverability, security, and compliance reviews relevant to your use.
5. Content restrictions and illegal-content notices
We may investigate, restrict the processing of, remove, or disable access to Customer Content, accounts, or features where we reasonably believe this is necessary because the content or use is illegal, violates these Terms, threatens security or email-system integrity, or infringes third-party rights. We will consider the rights and legitimate interests of affected parties and give reasons where required by law.
Send a notice of suspected illegal content to me@paukraft.com. It should explain why the content is considered illegal, identify its exact electronic location or provide the message or resource identifier, provide the notifier's name and email address where legally required, and confirm a good-faith belief that the notice is accurate and complete.
A customer affected by a restriction may challenge it by replying to our notice or emailing the address above with the decision and reasons for the challenge. This does not limit judicial, regulatory, or statutory consumer remedies.
6. AI-assisted features
Classification, opt-out detection, and semantic thread matching use probabilistic systems and can be incomplete or incorrect. You must assess outputs for your use case and must not rely on them as the sole basis for decisions with legal or similarly significant effects on individuals.
AI Inbx does not guarantee that every unsubscribe, complaint, thread, category, or harmful message will be detected. You remain responsible for your communications and actions taken from an output.
7. Plans, fees, payment, and taxes
Fees, included usage, billing periods, overage rates, and payment terms are shown before you place a paid order. Consumer prices shown at checkout include VAT and other unavoidable charges. Prices for Business Customers may be shown net of VAT where clearly identified. Usage-based charges are calculated from our service records using the method disclosed with the plan.
Recurring plans renew for the period disclosed at checkout until cancelled. You can cancel through the cancellation function made available in the account or by the merchant of record. Cancellation takes effect at the end of the already-paid billing period unless a statutory right, checkout term, or plan gives an earlier date.
We may change a price only for a future renewal period and will give at least 30 days' notice. You may cancel before the new price takes effect. Overdue undisputed amounts may accrue statutory interest, and we may suspend paid features after notice if an amount remains overdue.
8. Consumer withdrawal and cancellation
If you are a Consumer and conclude a distance contract, you generally have a statutory right to withdraw within 14 days without giving a reason. The withdrawal information and model form at /withdrawal explain how to exercise that right. A merchant of record may offer an additional or longer refund policy; that does not reduce statutory rights.
If you expressly request that a paid service begin during the withdrawal period and then withdraw, you may have to pay the proportionate amount for service already supplied, but only where the statutory conditions are met. Any loss or expiry of the withdrawal right occurs only under mandatory law and after the notices and express confirmations required by that law.
Consumers may also end recurring paid plans using the continuously available cancellation function provided with the subscription. Statutory rights concerning digital services, defects, conformity, remedies, termination, and refunds cannot be waived by these Terms.
9. Customer Content, privacy, and confidentiality
As between the parties, you retain your rights in data, messages, domains, configurations, and other material you provide or receive through the Service (“Customer Content”). You grant us the non-exclusive rights necessary to host, transmit, process, reproduce, and otherwise handle Customer Content solely to provide, secure, support, and maintain the Service and comply with law.
Our Privacy Policy applies where we act as a controller. Where we process personal data on your behalf as a processor, the Data Processing Agreement is incorporated into the contract. The DPA applies according to the parties' actual data-protection roles, regardless of whether the Customer is a Consumer or Business Customer.
Each party will protect the other party's non-public technical, security, and business information using reasonable care and use it only to perform the contract. This does not cover information that is public without breach, already lawfully known, independently developed, or lawfully received from a third party. A legally compelled disclosure is permitted after notice where legally allowed.
10. Intellectual property and feedback
AI Inbx and its licensors retain all rights in the Service, documentation, software, designs, and brands. You receive a non-exclusive, non-transferable right to use the Service during the contract term for personal or professional purposes and permitted product integrations.
Feedback may be used without restriction or payment, provided we do not identify you or disclose confidential information.
11. Term, termination, and suspension
The contract runs for the period stated in the plan or order. If no fixed period is stated, either party may terminate it at the end of the current billing period. You may close a free account at any time. Statutory withdrawal and termination rights remain unaffected.
We may suspend affected access immediately where reasonably necessary to address a security risk, unlawful use, material abuse, harm to email reputation or third parties, a binding authority request, or a material breach. Where practical, we will give notice and an opportunity to cure and limit suspension to what is necessary.
After termination, access ends and Customer Content is returned or deleted under the DPA and Privacy Policy, subject to legal retention duties and reasonable technical deletion cycles. Export content you need before closing a workspace or account.
12. Conformity, updates, and warranty
Consumers have the statutory rights that apply to digital products and services. We will supply updates, including security updates, required to keep the Service in conformity for the legally required period. If the Service lacks conformity, Consumers may require that it be brought into conformity and may have rights to a price reduction, termination, damages, or reimbursement under applicable law.
For all customers, statutory defect rights apply subject to the agreed service description. Please report reproducible defects and provide information reasonably needed to investigate. We may remedy a defect by repair, replacement, workaround, or re-performance where legally permitted.
We are not responsible for a defect caused solely by unauthorized changes, unsupported combinations, customer systems, third-party services, or use contrary to documentation. This does not exclude responsibility where the defect would have occurred regardless or mandatory law provides otherwise.
13. Liability
We are liable without limitation for intent and gross negligence; for injury to life, body, or health; under the German Product Liability Act; for fraudulently concealed defects; and to the extent of an express guarantee.
For slight negligence, we are liable for breach of an essential contractual obligation whose performance makes the contract possible and on whose performance the customer may regularly rely. In that case, liability is limited to foreseeable damage typical for this type of contract. In other cases, liability for slight negligence is excluded to the extent legally permitted. These limitations also apply to our representatives and agents.
Where recoverable data-loss damage results from a Business Customer's failure to maintain reasonable, current backups or exports, damages are limited to the restoration cost that would have arisen with proper backup practices. Mandatory statutory liability and Consumer rights remain unaffected.
14. Additional Business Customer terms
This Section applies only to Business Customers. A Business Customer will indemnify us against third-party claims, reasonable costs, and damages arising from unlawful Customer Content or a culpable breach of Section 4, to the extent it is responsible. We will promptly notify the Business Customer, allow reasonable control of the defense, and provide reasonable cooperation. No settlement admitting our fault or imposing non-monetary duties on us may be made without our consent.
A Business Customer may set off or exercise a right of retention only with claims that are undisputed, finally adjudicated, or arise from the same contractual relationship, except where mandatory law provides otherwise.
15. Changes to the Service and Terms
We may change these Terms for future contracts. For an ongoing contract, we may make reasonable changes required by law or security, to prevent abuse, to reflect new or changed Service features, or to improve the Service, provided the change does not upset the contract's essential balance.
For Consumers receiving a digital service continuously, a change beyond what is necessary to maintain conformity will be made only for a valid reason stated above, without additional cost, and with clear notice. If such a change negatively affects access or use more than minimally, we will provide advance information on a durable medium and any statutory right to terminate without charge.
We will give at least 30 days' notice of other material changes to an ongoing contract. If a change materially disadvantages you, you may terminate before it takes effect. Where acceptance is legally required, we will ask for it rather than treating silence as consent.
16. Final provisions
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For a Consumer, this choice does not deprive them of mandatory protections of the country where they habitually reside.
If the Customer is a merchant, legal entity under public law, or special fund under public law, the exclusive venue is Freiburg im Breisgau, Germany. Mandatory venues, including those available to Consumers, remain unaffected.
A transfer of the contract by you requires our prior consent, which will not be unreasonably withheld. If a provision is invalid, the statutory rule applies and the remaining provisions continue where legally possible. We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board.
