Terms of Service

Last updated: April 2, 2026

1. Acceptance of Terms

By accessing or using the services provided by NorthHorizonMails ("Company," "we," "our," or "us"), you ("Customer," "you") agree to be bound by these Terms of Service ("Terms"). If you do not agree to all of these Terms, do not use our services.

These Terms constitute a legally binding agreement between you and NorthHorizonMails. You represent that you have the authority to enter into this agreement, either personally or on behalf of a business entity.

2. Description of Services

NorthHorizonMails provides Microsoft Outlook inbox infrastructure services for cold email marketing, including:

  • Provisioning of individual US-based Microsoft 365 tenants and Outlook inboxes
  • DNS configuration (SPF, DKIM, DMARC) for customer domains
  • Integration of inboxes into third-party sending platforms (Instantly, Plusvibe, and others)
  • Domain replacement services for burned or penalized domains
  • Optional Deliverability Guarantee add-on (subject to separate terms within these Terms)

We reserve the right to modify, suspend, or discontinue any service at any time with reasonable notice, except where required by law.

3. Accounts and Orders

When you place an order, you agree to provide accurate and complete information. You are responsible for maintaining the confidentiality of any account credentials we provide.

Orders are processed on a per-domain, per-month basis. Setup is initiated within 24-48 hours of confirmed payment. Delivery timelines are estimates and may vary due to technical or operational circumstances.

You are responsible for the security of credentials delivered to you. We are not liable for unauthorized use of credentials after delivery.

4. Payment and Billing

All services are billed on a month-to-month basis unless otherwise agreed in writing. Prices are listed in USD. Payment is due at the time of order for the first billing period.

Recurring subscriptions are billed automatically on your renewal date. You authorize us to charge your payment method on file for all applicable fees.

All fees are non-refundable except as expressly stated in our Refund Policy or where the Deliverability Guarantee applies. We reserve the right to change pricing with 30 days' advance notice.

Payments are processed through Stripe. By purchasing, you also agree to Stripe's terms of service.

5. Acceptable Use

You agree to use our services only for lawful cold email outreach in compliance with applicable law, including the CAN-SPAM Act (US), CASL (Canada), GDPR (EU/UK), and any other applicable anti-spam regulations in your jurisdiction.

You may not use our services to:

  • Send unsolicited bulk email that violates CAN-SPAM, CASL, GDPR, or other applicable laws
  • Send emails containing malware, phishing links, or deceptive content
  • Harass, threaten, or abuse recipients
  • Impersonate individuals, companies, or organizations fraudulently
  • Operate spam operations, affiliate marketing schemes, or deceptive advertising
  • Violate any third-party platform terms (including Microsoft's Acceptable Use Policy)
  • Resell our infrastructure to third parties without prior written consent

We reserve the right to suspend or terminate your account immediately if we determine, in our sole discretion, that your use violates this policy. Violations may also be reported to relevant authorities.

You remain solely responsible for the content of all emails sent through our infrastructure. NorthHorizonMails is an infrastructure provider, not a sender of record, and bears no responsibility for your email content or its legal compliance.

6. Intellectual Property

All content on the NorthHorizonMails website — including text, design, graphics, and software — is owned by or licensed to NorthHorizonMails and is protected by applicable intellectual property laws.

You are granted a limited, non-exclusive, non-transferable license to use the services for your own internal business purposes. You may not copy, resell, sublicense, or reverse-engineer any part of our services.

7. Termination

You may cancel your service at any time. Month-to-month services remain active through the end of the paid billing period. We do not prorate cancellations.

We may suspend or terminate your access immediately, without notice, if you violate these Terms — particularly the Acceptable Use Policy. Upon termination for cause, no refund will be issued for unused periods.

Upon termination, your Microsoft tenant credentials and inbox access will be decommissioned. You are responsible for exporting any data you need before termination.

8. Disclaimers

Our services are provided "as is" and "as available" without warranties of any kind, express or implied, except as expressly stated in these Terms or the Deliverability Guarantee.

We do not warrant that our services will be uninterrupted, error-free, or that emails sent through our infrastructure will achieve any specific delivery rate, open rate, or reply rate — except as covered by the Deliverability Guarantee add-on under the conditions stated therein.

Deliverability outcomes depend on many factors outside our control, including your email copy, recipient list quality, engagement history, recipient mail server settings, and global spam filter changes. The Deliverability Guarantee covers only the infrastructure factors under our direct control.

9. Limitation of Liability

To the maximum extent permitted by applicable law, NorthHorizonMails shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of revenue, loss of data, loss of business opportunity, or damage to reputation, even if we have been advised of the possibility of such damages.

Our total aggregate liability to you for any claims arising from or related to these Terms or our services shall not exceed the total fees paid by you to us in the three (3) months preceding the event giving rise to the claim.

10. Governing Law and Disputes

These Terms are governed by and construed in accordance with the laws of the United States, without regard to conflict of law principles. Any disputes arising under these Terms shall be resolved through binding arbitration in accordance with the rules of the American Arbitration Association, except that either party may seek injunctive or other equitable relief in any court of competent jurisdiction.

11. Changes to These Terms

We may update these Terms from time to time. We will notify customers of material changes via email or a notice on our website at least 14 days before the changes take effect. Your continued use of our services after the effective date constitutes acceptance of the updated Terms.
