Last Updated: August 4, 2026
Sending.ac (“Sending.ac,” “we,” “us,” or “our”) is operated by Scale With Value Limited, a company incorporated in Hong Kong (“Company”). These Terms of Service (“Terms”) govern your access to and use of the Sending.ac platform, including our website, dashboard, APIs, domain provisioning tools, email infrastructure, and related services (collectively, the “Service”).
BY CREATING AN ACCOUNT, CLICKING “I AGREE,” OR OTHERWISE ACCESSING OR USING THE SERVICE, YOU AGREE TO BE BOUND BY THESE TERMS. IF YOU ARE ENTERING INTO THESE TERMS ON BEHALF OF A COMPANY OR OTHER LEGAL ENTITY, YOU REPRESENT THAT YOU HAVE THE AUTHORITY TO BIND THAT ENTITY. IF YOU DO NOT AGREE TO THESE TERMS, DO NOT USE THE SERVICE.
1. Description of Service
Sending.ac provides email infrastructure, including domain acquisition and provisioning, DNS configuration (including SPF, DKIM, and DMARC), Azure mailbox creation, backup infrastructure, deliverability-related configuration, and integrations that connect provisioned mailboxes to supported third-party sending and warm-up platforms (the “Service”). Sending.ac does not itself provide campaign sequencing. The Service is intended for businesses and individuals engaged in lawful outbound email communication, including sales and marketing outreach conducted in compliance with applicable law.
The Service is provided on a subscription and/or usage basis as described at checkout or in your applicable order form (“Order Form”). Features, limits, and pricing tiers may vary and are subject to change as described in Section 10.
2. Eligibility & Account Registration
2.1 Eligibility. You must be at least 18 years old and capable of forming a binding contract to use the Service. By registering, you represent that all information you provide is accurate, current, and complete.
2.2 Account Security. You are responsible for maintaining the confidentiality of your login credentials and API keys, and for all activity that occurs under your account. You must notify us immediately through the message bubble in the bottom-right corner of our website if you become aware of any unauthorized use of your account.
2.3 Business Use. The Service is designed primarily for business/commercial use. You represent that any domains, mailboxes, or sending infrastructure provisioned through the Service will be used solely for lawful business purposes.
2.4 Account Use. You may maintain the accounts, workspaces, or client environments permitted by your plan. You may not create duplicate accounts to evade usage limits, trial restrictions, payment obligations, or a suspension.
3. Acceptable Use Policy
You agree that you will NOT use the Service to:
Send unsolicited bulk email in violation of the CAN-SPAM Act, CASL, the EU ePrivacy Directive, GDPR, or any other applicable anti-spam or electronic communications law;
Send content that is fraudulent, deceptive, phishing-related, or that impersonates any person or entity;
Use false or misleading sender information, routing information, headers, identities, or subject lines;
Distribute malware, ransomware, or any other malicious code;
Harvest or scrape email addresses without a lawful basis for contacting the underlying individuals;
Fail to maintain accurate suppression lists, provide a legally compliant opt-out method, honor unsubscribe requests within the period required by applicable law, or include required sender identification and address information;
Send content that is defamatory, obscene, hateful, harassing, or that promotes violence or illegal activity;
Engage in any activity that would cause Sending.ac’s, a customer’s, or an upstream provider’s IP addresses, domains, mailboxes, or infrastructure to be blocklisted, restricted, or suspended, or that otherwise threatens the deliverability or reputation of the Service;
Violate any third party’s intellectual property, privacy, or other legal rights;
Circumvent, disable, or otherwise interfere with security-related features of the Service, including rate limits, sending caps, or warm-up schedules;
Resell or sublicense the Service as a standalone product without our express written consent. Agencies may use the Service to manage lawful infrastructure for their clients, but remain responsible for each client’s activity, compliance, and use of the Service;
Use the Service in any manner that violates applicable export control or sanctions law.
Enforcement. We reserve the right, but not the obligation, to monitor use of the Service for compliance with this Acceptable Use Policy. Violation of this Section may result in immediate suspension or termination of your account without refund, in addition to any other remedies available to us at law, including recovery of costs incurred due to blocklisting, carrier penalties, or reputational harm caused by your use of the Service.
4. Fees, Billing & Payment
4.1 Subscription Fees. Fees for the Service are described at checkout, in your Order Form, or on our pricing page, and are billed in advance on a recurring basis (monthly or annually, as selected) unless otherwise agreed in writing.
4.2 Payment Method. You authorize us (or our third-party payment processor) to charge your designated payment method on a recurring basis until you cancel your subscription in accordance with these Terms.
4.3 Taxes. Fees are exclusive of applicable taxes, levies, or duties, which you are responsible for, excluding taxes based on our net income.
4.4 Failed Payments. If a payment fails, we will attempt to notify you and may retry the charge. If payment is not successfully collected within a commercially reasonable period, we reserve the right to suspend or downgrade your account and restrict or revoke access to domains and mailboxes in accordance with Section 6.
4.5 Price Changes. We may change our fees prospectively upon reasonable notice (e.g., 30 days). Continued use of the Service after a price change takes effect constitutes acceptance of the new pricing.
5. Refund Policy
This Refund Policy is a binding part of these Terms of Service.
5.1 General Rule — No Refunds. Sending.ac is an infrastructure and software service. Fees paid for subscription periods, domain provisioning, mailbox setup, integration or configuration services, backup infrastructure, or any other feature of the Service are non-refundable, in whole or in part, except as expressly set forth in this Section 5 or as required by applicable law. This includes, without limitation:
Partial-month or partial-billing-cycle cancellations;
Unused mailboxes, domains, or plan capacity within a billing period;
Downgrades made mid-cycle;
Suspension or termination of your account resulting from a violation of the Acceptable Use Policy (Section 3).
5.2 Rationale. Provisioning domains, DNS records, Azure mailboxes, cloud resources, and backup infrastructure involves real, largely non-recoverable third-party costs incurred by us at the time of purchase or renewal, regardless of your subsequent usage.
5.3 Limited Exceptions. We may, at our sole discretion, issue a full or partial refund in cases of:
A verified billing error or duplicate charge caused by our systems;
A documented, prolonged Service outage attributable solely to us that materially prevented use of core functionality, subject to our Service Level commitments (if any, as set out in your Order Form);
Circumstances required by mandatory consumer protection law in your jurisdiction (e.g., certain EU consumer withdrawal rights for first-time purchases by individual consumers, where applicable).
5.4 How to Request. Refund requests under Section 5.3 must be submitted through the message bubble in the bottom-right corner of our website within 14 days of the disputed charge, including your account details and a description of the issue. We will respond within a commercially reasonable timeframe.
5.5 Chargebacks. Initiating a chargeback or payment dispute with your bank or card issuer without first contacting us in good faith constitutes a material breach of these Terms and may result in immediate suspension or termination of your account and restriction of associated domain and mailbox services under Section 6.
6. Domain Provisioning, Ownership & Transfers
6.1 Types of Domains. You may connect a domain that you already own or control (a “Customer-Owned Domain”), or you may ask us to register or provision a domain through the Service (a “Sending.ac-Managed Domain”). The applicable plan, checkout terms, or Order Form will describe the registration, renewal, management, and transfer terms for a Sending.ac-Managed Domain.
6.2 Authorization. You represent that you have authority to connect each Customer-Owned Domain and authorize us to configure its DNS records, authentication settings, redirects, and related infrastructure as needed to provide the Service.
6.3 Registration and Renewal. Domain availability is not guaranteed until registration is completed. Registration and renewal are subject to registrar and registry requirements, pricing, transfer locks, grace periods, and other third-party rules. You are responsible for keeping your account in good standing and completing any action required to register, renew, verify, or transfer a domain.
6.4 Ownership and Use. You retain your rights in Customer-Owned Domains. Rights in a Sending.ac-Managed Domain depend on the plan or Order Form under which it was provisioned. Where a domain is purchased as a separately priced registration for your use, you may request transfer to your own registrar account, subject to payment of outstanding amounts and applicable registrar or registry restrictions. A domain supplied only as part of managed infrastructure may remain under our or our provider’s control unless the applicable plan or Order Form states otherwise.
6.5 Transfers. Transfer requests must be submitted through the dashboard or through the message bubble in the bottom-right corner of our website. We will make commercially reasonable efforts to facilitate eligible transfers, but we are not responsible for delays or failures caused by registrar locks, registry rules, DNS propagation, third-party providers, inaccurate information, unpaid amounts, or your failure to complete required steps.
6.6 Cancellation, Suspension, or Termination. When a subscription ends, access to associated mailboxes, DNS management, backup infrastructure, and other Service features may be disabled. Customer-Owned Domains remain yours, although configurations managed through the Service may stop functioning. Sending.ac-Managed Domains may expire, become unavailable, or be released in accordance with the applicable plan, Order Form, registrar rules, and any completed transfer request. You should request any eligible transfer before canceling whenever reasonably possible.
6.7 Domain and Provider Risks. We do not guarantee that any domain, mailbox, provider account, DNS configuration, or IP address will remain available, transferable, active, unrestricted, or free from reputation issues. Registrars, registries, Microsoft, Azure, and other providers may reject, delay, limit, suspend, or terminate services independently of Sending.ac.
7. Intellectual Property
7.1 Our IP. The Service, including all software, platform design, documentation, trademarks, and underlying technology, is owned by the Company or its licensors and is protected by intellectual property laws. These Terms do not grant you any rights to our intellectual property except the limited right to use the Service as expressly permitted herein.
7.2 Your Content. You retain all rights to content, email copy, contact lists, and other materials you upload or transmit through the Service (“Customer Content”). You grant us a limited, non-exclusive, worldwide license to host, process, transmit, and display Customer Content solely as necessary to provide the Service.
7.3 Feedback. If you provide suggestions, ideas, or feedback about the Service, we may use them without restriction or obligation to you.
8. Customer Data & Privacy
Our collection and use of personal data in connection with the Service is described in our Privacy Policy, which is incorporated into these Terms by reference. By using the Service, you also agree to comply with applicable data protection laws with respect to any personal data of third parties that you process or transmit through provisioned mailboxes or connected platforms. Where required by applicable law, the parties may enter into a separate Data Processing Addendum (“DPA”) governing our processing of personal data on your behalf.
9. Third-Party Services & Integrations
The Service depends on or may connect with third-party services, including domain registrars, Microsoft and Azure infrastructure, and sending or warm-up platforms such as Instantly and Smartlead. We are not responsible for the availability, functionality, security, enforcement decisions, or data practices of third-party services, and your use of them is governed by their own terms and policies.
10. Service Availability & Modifications
We strive to maintain high availability but do not guarantee uninterrupted or error-free operation of the Service. We may modify, suspend, or discontinue any feature of the Service at any time, with notice where reasonably practicable, provided that we will not materially reduce core functionality during a paid term without a pro-rated remedy where required by law.
11. Disclaimers of Warranties
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT EMAIL DELIVERABILITY, INBOX PLACEMENT, OR SENDING REPUTATION OUTCOMES WILL MEET ANY PARTICULAR STANDARD, AS THESE ARE SUBSTANTIALLY INFLUENCED BY THIRD-PARTY MAILBOX PROVIDERS, SPAM FILTERING SYSTEMS, AND YOUR OWN SENDING PRACTICES AND CONTENT, WHICH ARE OUTSIDE OUR CONTROL.
12. Limitation of Liability
12.1 TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT SHALL THE COMPANY, ITS OFFICERS, DIRECTORS, EMPLOYEES, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITY, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE, INCLUDING LOSSES RELATED TO DOMAIN, MAILBOX, DNS, PROVIDER, TRANSFER, DELIVERABILITY, OR REPUTATION ISSUES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
12.2 OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE TOTAL FEES PAID BY YOU TO US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.
12.3 Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above limitations may not apply to you to the extent prohibited by mandatory law.
13. Indemnification
You agree to defend, indemnify, and hold harmless the Company and its officers, directors, employees, and agents from and against any claims, damages, losses, liabilities, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your use of the Service in violation of these Terms or applicable law; (b) Customer Content; (c) your violation of any third party’s rights, including recipients of communications sent through the Service; or (d) any dispute arising from a domain that you connect, register, manage, or request to transfer through the Service.
14. Term, Suspension & Termination
14.1 Term. These Terms remain in effect for as long as you maintain an account or otherwise use the Service.
14.2 Termination by You. You may cancel your subscription at any time through your account dashboard or by contacting us through the message bubble in the bottom-right corner of our website. Cancellation is effective at the end of your current billing cycle unless otherwise stated. Domain and mailbox services following cancellation are handled under Section 6.
14.3 Termination or Suspension by Us. We may suspend or terminate your account, with or without notice, if: (a) you breach these Terms, including the Acceptable Use Policy; (b) required by law or a competent authority; (c) your use poses a security or deliverability risk to other customers; or (d) payment fails and is not cured within a reasonable period.
14.4 Effect of Termination. Upon termination, your right to access the Service ceases immediately. Sections 5, 6, 7, 11, 12, 13, 15, and 17 survive termination. Domain and mailbox lifecycle, access, and transfer matters are governed by Section 6.
15. Governing Law & Dispute Resolution
15.1 Governing Law. These Terms are governed by the laws of the Hong Kong Special Administrative Region, without regard to conflict-of-law principles, except where mandatory local consumer protection law requires application of another jurisdiction’s law.
15.2 Dispute Resolution. Any dispute arising out of or relating to these Terms shall first be addressed through good-faith negotiation. If unresolved within 30 days, the dispute shall be referred to and finally resolved by arbitration administered by the Hong Kong International Arbitration Centre (HKIAC) under the HKIAC Administered Arbitration Rules, seated in Hong Kong, conducted in English, before a single arbitrator.
15.3 Injunctive Relief. Notwithstanding the above, either party may seek injunctive or equitable relief in any court of competent jurisdiction to protect its intellectual property or confidential information.
16. Changes to These Terms
We may update these Terms from time to time. Material changes will be notified via email or in-app notice at least 14 days before taking effect. Continued use of the Service after the effective date of updated Terms constitutes your acceptance of them.
17. General Provisions
17.1 Entire Agreement. These Terms, together with any Order Form, DPA, and our Privacy Policy, constitute the entire agreement between you and the Company regarding the Service.
17.2 Severability. If any provision of these Terms is found unenforceable, the remaining provisions remain in full force and effect.
17.3 No Waiver. Failure to enforce any right or provision shall not constitute a waiver of such right or provision.
17.4 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 assets.
17.5 Force Majeure. Neither party is liable for delays or failures in performance resulting from causes beyond its reasonable control, including internet or carrier outages, natural disasters, or governmental action.
17.6 Relationship of Parties. Nothing in these Terms creates a partnership, joint venture, employment, or agency relationship between you and the Company.
