2. Definitions

For the purposes of these Terms, the following definitions apply:

• “Warmbox Services” or “Services” encompass email warm-up solutions, automated email interactions, reputation-building algorithms, and related infrastructure provided by Warmbox.
• “Users” include individuals, companies, or organizations that access or use the Services. A “Consumer” means a natural person who is acting for purposes which are outside his or her trade, business, craft or profession, within the meaning of Directive 2011/83/EU and § 34 of the Estonian General Part of the Civil Code Act; a “Business User” means any User who is not a Consumer.
• “Third-Party Providers” refer to external email service providers (ESPs), hosting providers, or any other integrated third-party service, including but not limited to Google Workspace and Microsoft 365.
• “ESP Terms of Service” refer to the terms and policies imposed by third-party email providers governing their infrastructure.
• “Misuse” includes spam, phishing, abuse of email systems, violation of ESP policies, or any illegal activities.
• “Force Majeure Event” includes unforeseen circumstances beyond Warmbox’s reasonable control, such as natural disasters, cyberattacks, regulatory actions, war, labour disputes, failures of telecommunications networks, and changes in third-party policies, within the meaning of § 103 of the Estonian Law of Obligations Act (Võlaõigusseadus, “LOA”).

The Warmbox Services are designed to assist Users in improving their email deliverability by simulating legitimate email interactions that build sender reputation over time. This service requires adherence to ESP regulations and industry best practices. Users must understand that Warmbox does not control ESPs and cannot guarantee specific deliverability outcomes. The effectiveness of the Services depends on various factors, including the consistency of email behavior, engagement levels, and sender history.

Users must ensure that they use the Services within the legal and ethical framework established by applicable data protection and electronic communications regulations, including Regulation (EU) 2016/679 (“GDPR”), Directive 2002/58/EC (“ePrivacy Directive”), the Estonian Electronic Communications Act, the CCPA, and other applicable laws. Any violation of such laws by Users will be their sole responsibility.

3. Acceptance of Terms; Eligibility

By accessing and using the Services, you represent and warrant that: (a) you have the legal capacity and authority to enter into this agreement (and, where you act on behalf of a legal entity, that you are duly authorised to bind that entity); (b) you are at least 18 years of age; and (c) you will comply with all applicable laws, regulations, and ESP Terms of Service. You further acknowledge the inherent risks of email warm-up services and their dependency on external factors. If you do not agree to these Terms, you must not access or use the Services.

Users must not engage in activities that could be considered fraudulent, deceptive, or unethical when using the Services. By continuing to use the platform, Users affirm their understanding of these Terms and their commitment to responsible and lawful use.

Warmbox reserves the right, subject to Section 14 (Suspension and Termination), to deny access to, suspend, or terminate the accounts of Users who are found to be in breach of these Terms.

4. Service Description

Warmbox provides email warm-up solutions designed to improve inbox reputation and deliverability. The Services automate warm-up sequences that simulate real interactions, offer customizable email behavior settings, provide analytical dashboards with inbox performance insights, and integrate with external email services such as Google Workspace and Microsoft 365.

Warmbox does not own or control Third-Party Providers and, to the extent permitted by applicable law, cannot be held responsible for any restrictions, limitations, or suspensions imposed by them. If an ESP enforces restrictions on an inbox due to policy considerations, Warmbox is not liable for any resulting service limitations, provided such limitations are not attributable to Warmbox’s own breach of these Terms. Service effectiveness may vary depending on the User’s domain reputation, email practices, and third-party provider rules.

Users acknowledge that results may vary based on factors beyond Warmbox’s control, including but not limited to the age of the email domain, frequency of email sends, content quality, recipient engagement rates, and changes in ESP algorithms. The Services are provided as a means (obligation of means) and not as a guarantee of specific results.

Users are responsible for ensuring that their use of the Services complies with all applicable laws governing electronic communications, direct marketing and data privacy. Failure to do so may result in the suspension or termination of their account in accordance with Section 14.

5. Account Registration and User Responsibilities

To use the Services, Users must provide accurate, current and truthful information, maintain the confidentiality of their login credentials, and immediately notify Warmbox of any unauthorized access to their account. Users are responsible for all activities carried out under their account, except where such activities result from a failure of Warmbox’s own security measures.

Users are responsible for ensuring that their use of Warmbox complies with all applicable laws and regulations. Any Misuse, fraudulent activity, or attempt to bypass ESP policies may result in suspension or termination of the account in accordance with Section 14 and, where necessary, further legal action.

Warmbox may conduct compliance audits to verify that Users are not violating any provision of these Terms. Users found engaging in prohibited activities will be subject to the measures set out in Section 14.

6. Acceptable Use and Misuse Policy

Users are strictly prohibited from:

• sending spam, phishing emails, or any form of unsolicited commercial communications in violation of applicable law (including Directive 2002/58/EC, the Estonian Electronic Communications Act, the CAN-SPAM Act, or equivalent legislation);
• engaging in fraudulent, deceptive, or abusive practices, or manipulating email interactions in violation of ESP guidelines;
• using the Services for illegal or harmful activities of any kind;
• introducing malware, bots, or any malicious code into the Warmbox infrastructure;
• attempting to bypass, probe, or circumvent security measures, or exploiting vulnerabilities in the Services.

To maintain service integrity, Warmbox may conduct routine audits of User activities. If unauthorized, fraudulent, or non-compliant activity is detected, Warmbox may suspend or disable the offending account and the associated inboxes in accordance with Section 14. Users found attempting to bypass security measures or exploit vulnerabilities may be reported to the relevant authorities.

7. Third-Party Providers

Warmbox does not control the actions of Third-Party Providers and, to the extent permitted by applicable law, is not liable for changes they implement that may affect the Services. If ESPs modify their policies, suspend email accounts, or restrict certain features, Warmbox cannot be held responsible for any resulting disruptions. Users remain bound at all times by the applicable ESP Terms of Service, which apply in addition to these Terms.

8. Subscriptions, Payment Terms and Billing

Payments for the Services are processed by Paddle.com Market Ltd. and/or its affiliates (“Paddle”), acting as authorized reseller and merchant of record. By purchasing a subscription, you also enter into a contractual relationship with Paddle under Paddle’s own terms of sale, which govern the billing relationship (including invoicing, payment processing, applicable taxes and VAT collection). All transactions are securely handled in compliance with applicable financial regulations.

Subscriptions are offered on a recurring basis (e.g., monthly or annual) and renew automatically at the end of each billing period at the then-current price, unless cancelled before the renewal date. The subscription price, billing frequency and renewal terms are clearly displayed prior to purchase. You may cancel your subscription at any time through your account settings or by contacting contact@warmbox.ai; cancellation takes effect at the end of the current billing period, and cancellation is no more burdensome than subscribing. Failure to maintain an active, paid subscription may result in suspension or termination of access to the Services.

Except as provided in Section 9 (Consumer Right of Withdrawal), in Section 10 (Conformity of the Services), or as otherwise required by mandatory applicable law, payments are non-refundable and no refunds or credits will be granted for partially used billing periods.

9. Consumer Right of Withdrawal

This Section 9 applies only to Users who qualify as Consumers within the European Union or the European Economic Area.

In accordance with Directive 2011/83/EU and §§ 52–56 of the Estonian Law of Obligations Act, Consumers have the right to withdraw from a distance contract for the provision of digital services within fourteen (14) days of the conclusion of the contract, without giving any reason. To exercise this right, the Consumer must inform Warmbox of their decision by an unequivocal statement sent to contact@warmbox.ai (or by using the electronic withdrawal function made available on the website). If the Consumer withdraws within this period, Warmbox will reimburse all payments received without undue delay and no later than fourteen (14) days from the day on which Warmbox is informed of the withdrawal, using the same means of payment used for the initial transaction.

If the Consumer expressly requests that the provision of the Services begin before the expiry of the withdrawal period, and acknowledges that they thereby lose the right of withdrawal once the service has been fully performed, the Consumer shall, in the event of withdrawal before full performance, pay Warmbox an amount proportionate to the services provided up until the time of withdrawal, in accordance with Article 14(3) of Directive 2011/83/EU.

Nothing in these Terms affects the mandatory rights of Consumers under the law of their country of habitual residence.

10. Conformity of the Services (Consumers)

Where the User is a Consumer, the Services are supplied in accordance with Directive (EU) 2019/770 on contracts for the supply of digital content and digital services, as transposed into the Estonian Law of Obligations Act. In the event of a lack of conformity of the Services, the Consumer is entitled to the statutory remedies provided by applicable law, including having the Services brought into conformity, a proportionate reduction of the price, or termination of the contract. These statutory remedies are not limited or excluded by anything in these Terms.

11. Intellectual Property

Warmbox and its licensors retain full ownership of the Services, including all software, user interfaces, branding, trademarks, algorithms, documentation and underlying technology, together with all associated intellectual property rights. Subject to compliance with these Terms and payment of the applicable fees, Warmbox grants the User a limited, non-exclusive, non-transferable, revocable licence to access and use the Services for the User’s internal purposes during the term of the subscription.

Users are not permitted to copy, reverse-engineer, decompile, disassemble, modify, create derivative works of, or distribute any part of the Services without Warmbox’s explicit prior written permission, except to the extent such restriction is prohibited by mandatory applicable law (including Articles 5 and 6 of Directive 2009/24/EC on the legal protection of computer programs). Users retain all rights in the content and data they submit to the Services.

12. Confidentiality

Users must not disclose or use, other than as necessary to use the Services, proprietary or confidential information relating to Warmbox’s algorithms, methodologies, pricing, or internal processes. Warmbox shall likewise treat the User’s non-public information as confidential and shall not disclose it to third parties except as necessary to provide the Services, as described in the Privacy Policy, or as required by law. This obligation survives the termination of these Terms for a period of five (5) years. Any breach of confidentiality may give rise to legal action.

13. Data Protection and Privacy

Warmbox processes personal data in accordance with Regulation (EU) 2016/679 (GDPR), the Estonian Personal Data Protection Act, and its Privacy Policy, which is available on the Warmbox website and forms an integral part of these Terms. The Privacy Policy describes the categories of data processed, the purposes and legal bases of the processing, retention periods, and the rights of data subjects (including the rights of access, rectification, erasure, restriction, portability and objection), together with the right to lodge a complaint with a supervisory authority, in particular the Estonian Data Protection Inspectorate (Andmekaitse Inspektsioon).

Where, in the course of providing the Services to a Business User, Warmbox processes personal data on behalf of that User as a processor within the meaning of Article 28 GDPR, such processing is governed by Warmbox’s Data Processing Agreement (DPA), available upon request at contact@warmbox.ai, which forms part of the contract between Warmbox and the Business User. The User, as controller, remains responsible for ensuring that a lawful basis exists for the personal data it submits to the Services.

14. Suspension and Termination

Warmbox may suspend or restrict access to the Services, in whole or in part, where: (a) the User materially breaches these Terms, including the Acceptable Use and Misuse Policy in Section 6; (b) suspension is necessary to protect the security or integrity of the Services or of Third-Party Providers; (c) suspension is required by law, by a competent authority, or by an ESP; or (d) subscription fees remain unpaid after notice and a reasonable cure period. Where practicable and lawful, Warmbox will give the User prior notice and an opportunity to remedy the breach; however, in cases of serious Misuse (including spam, phishing, malware or unlawful activity), Warmbox may suspend or terminate the account with immediate effect and without prior notice.

Warmbox may terminate the contract with immediate effect for good cause (mõjuv põhjus) in accordance with § 196 of the Estonian Law of Obligations Act. Users may cancel their subscription at any time as described in Section 8. Upon termination, the User’s right to access the Services ceases, and Warmbox will delete or return User data in accordance with the Privacy Policy and, where applicable, the DPA. Except where termination results from Warmbox’s breach or as provided in Sections 9 and 10, no refunds will be provided for the remainder of a paid billing period. Suspended or terminated accounts in breach of these Terms are not entitled to compensation or damage claims, without prejudice to mandatory statutory rights.

15. Warranties and Disclaimers

Warmbox will provide the Services with reasonable skill and care and substantially in accordance with their description. Except as expressly set out in these Terms, and to the maximum extent permitted by applicable law, the Services are provided “as is” and “as available” to Business Users, and Warmbox disclaims all other warranties, whether express, implied or statutory, including any implied warranties of merchantability, fitness for a particular purpose and non-infringement. Warmbox does not warrant that the Services will be uninterrupted, error-free or that they will achieve any particular deliverability outcome. Nothing in this Section limits the statutory conformity rights of Consumers under Section 10.

16. Limitation of Liability

Nothing in these Terms excludes or limits Warmbox’s liability for: (a) death or personal injury; (b) intentional breach or gross negligence (§ 106(2) of the Estonian Law of Obligations Act); (c) fraud or fraudulent misrepresentation; or (d) any other liability which cannot be excluded or limited under applicable law, including mandatory consumer protection law.

Subject to the foregoing, Warmbox’s total aggregate liability arising out of or in connection with these Terms and the Services, whether in contract, tort or otherwise, shall be limited to the total amount of fees paid by the User to Warmbox (via Paddle) during the twelve (12) months preceding the event giving rise to the claim.

Subject to the first paragraph of this Section, Warmbox shall not be liable for: ESP-imposed penalties, suspensions or inbox restrictions attributable to the User’s email practices; loss of profits, revenue, business or anticipated savings; loss or corruption of data (to the extent the User failed to maintain reasonable backups); or any indirect or consequential damages caused by service disruptions or changes implemented by Third-Party Providers. With respect to Consumers, this Section applies only to the extent permitted by Directive 93/13/EEC on unfair terms in consumer contracts and §§ 35–45 of the Estonian Law of Obligations Act governing standard terms.

17. Indemnification

Business Users agree to indemnify and hold Warmbox, its officers, directors, employees and agents harmless against any third-party claims, damages, penalties, or reasonable legal costs arising from: (a) the User’s violation of these Terms; (b) ESP restrictions caused by the User’s actions; (c) the User’s violation of applicable law, including anti-spam and data protection legislation; or (d) any unauthorized use of the Services under the User’s account. In respect of Consumers, this Section applies only to claims arising from the Consumer’s unlawful or wilful conduct and only to the extent permitted by applicable consumer protection law.

18. Force Majeure

Neither party shall be liable for any failure or delay in the performance of its obligations (other than payment obligations) to the extent caused by a Force Majeure Event, in accordance with § 103 of the Estonian Law of Obligations Act. The affected party shall notify the other party without undue delay and shall use reasonable efforts to mitigate the effects of the Force Majeure Event. If a Force Majeure Event persists for more than sixty (60) consecutive days, either party may terminate the affected subscription with immediate effect, in which case the User shall be entitled to a pro-rata refund of prepaid fees corresponding to the unused portion of the subscription period.

19. Modifications to these Terms

Warmbox may update these Terms from time to time for valid reasons, including changes in law or regulation, changes to the Services, or security requirements. Material changes will be notified to Users by email or through the Services at least thirty (30) days before they take effect. If a User does not agree to the modified Terms, the User may terminate the subscription with effect from the date on which the changes take effect; in that case, any prepaid fees relating to periods after termination will be refunded pro rata. Continued use of the Services after the effective date of the revised Terms constitutes acceptance of the revised Terms. The version applicable to each billing period is the version in force at the start of that period, and prior versions are available upon request.

20. Governing Law and Dispute Resolution

These Terms, and any dispute or claim arising out of or in connection with them, are governed by the laws of the Republic of Estonia, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods (CISG). If the User is a Consumer, this choice of law does not deprive the Consumer of the protection afforded by provisions that cannot be derogated from by agreement under the law of the country of the Consumer’s habitual residence (Article 6(2) of Regulation (EC) No 593/2008, “Rome I”).

The parties shall first attempt to resolve any dispute amicably through good-faith negotiation; Users are invited to contact Warmbox at contact@warmbox.ai. If no resolution is reached within sixty (60) days, disputes shall be referred to Harju County Court (Harju Maakohus) in Tallinn, Estonia, as the court of first instance. If the User is a Consumer domiciled in the European Union, the Consumer may also bring proceedings before, and may only be sued in, the courts of the Member State of the Consumer’s domicile (Articles 17–18 of Regulation (EU) No 1215/2012, “Brussels I recast”).

Consumers residing in Estonia may also refer disputes to the Consumer Disputes Committee (Tarbijavaidluste komisjon) operating at the Estonian Consumer Protection and Technical Regulatory Authority (www.ttja.ee), a recognised alternative dispute resolution body under Directive 2013/11/EU. Warmbox will consider participation in ADR proceedings in good faith.

21. General Provisions

21.1 Severability

If any provision of these Terms is held to be invalid, void or unenforceable, in whole or in part, by a court or competent authority, that provision shall be deemed modified to the minimum extent necessary to make it valid and enforceable or, if that is not possible, severed, and the remaining provisions shall continue in full force and effect.

21.2 Entire Agreement

These Terms, together with the Privacy Policy, any applicable DPA and any order or subscription confirmation, constitute the entire agreement between the parties with respect to the Services and supersede all prior agreements, negotiations and understandings, whether written or oral, relating to their subject matter. This clause does not exclude liability for fraudulent misrepresentation.

21.3 Assignment

Users may not assign or transfer their rights or obligations under these Terms without Warmbox’s prior written consent. Warmbox may assign these Terms to an affiliate or in connection with a merger, acquisition, corporate reorganisation or sale of all or substantially all of its assets, provided that the assignment does not reduce the User’s rights under these Terms.

21.4 No Waiver

A failure or delay by either party to exercise any right or remedy under these Terms shall not constitute a waiver of that right or remedy, nor shall any single or partial exercise preclude any further exercise of that or any other right or remedy.

21.5 Survival

Sections which by their nature are intended to survive termination — including Sections 11 (Intellectual Property), 12 (Confidentiality), 16 (Limitation of Liability), 17 (Indemnification), 20 (Governing Law and Dispute Resolution) and this Section 21 — shall survive any termination or expiry of these Terms.

21.6 Notices

Notices to Warmbox shall be sent to contact@warmbox.ai or to the registered office address stated in Section 1. Notices to the User shall be sent to the email address associated with the User’s account and shall be deemed received on the business day following transmission.

21.7 Language

These Terms are drawn up in English. Translations may be provided for convenience; in the event of any discrepancy, the English version shall prevail, except where mandatory consumer protection law provides otherwise.
