End User License Agreement and Terms of Use

Effective and last updated: September 4, 2026

This End User License Agreement and Terms of Use ("Agreement") is a legal agreement between MailBond LLC, a California limited liability company ("MailBond", "we", "us", or "our"), and the individual or organization using the MailBond™ email security service, including its Microsoft Outlook add-in, websites, dashboards, APIs, and related services (collectively, the "Service").

1. Acceptance and Authority

By installing, accessing, or using the Service, you agree to this Agreement and our Privacy Policy. If you use the Service for an organization, you represent that you are authorized to accept this Agreement on that organization's behalf. If you do not agree, do not install, access, or use the Service.

If your organization has a separate written agreement with MailBond covering the Service, that agreement controls to the extent of any conflict with this Agreement.

2. Provider and Microsoft Relationship

The Service is licensed and provided by MailBond LLC, not by Microsoft Corporation. Microsoft is not a party to this Agreement and is not responsible for the Service, its support, maintenance, warranties, or claims relating to it. Microsoft Outlook, Microsoft 365, Microsoft Entra ID, Microsoft Azure, Microsoft Marketplace, and related Microsoft products and services are governed by Microsoft's own terms. Microsoft names and marks are the property of Microsoft and are used only to identify compatible products and services. MailBond does not claim Microsoft endorsement, sponsorship, or certification.

3. Service Description and Requirements

MailBond is an email security service for Microsoft Outlook. At a user's direction, it analyzes the currently selected message for signals that may include suspicious links, sender authentication, social-engineering language, supported attachments, image text, QR or barcode content, redirects, and domain reputation. The Service presents risk information to assist users and security teams; it does not replace professional judgment, security awareness, endpoint protection, email gateways, incident response, or other security controls.

Use requires a supported version of Microsoft Outlook or another expressly supported client, internet access, an active Microsoft work or school account, and an active MailBond entitlement provisioned by the user's organization. Some features may vary by client, platform, subscription, administrator configuration, or availability of message headers.

4. License Grant

Subject to this Agreement and any applicable order or subscription terms, MailBond grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable right to install and use the Service during the applicable subscription term solely for your organization's internal, lawful email security purposes. The Service is licensed, not sold. No rights are granted except those expressly stated in this Agreement.

5. Organizational Accounts and Authorized Users

An organization purchasing or receiving access to the Service is responsible for its authorized users, administrator decisions, license assignments, configuration, and compliance with this Agreement. Users must access the Service through their own authorized Microsoft identity and may not share credentials or attempt to use another person's account. Administrators are responsible for obtaining any notices, consents, or authorizations required to process organizational email content and related data through the Service.

6. Outlook Permissions, Data, and Privacy

The Outlook add-in requests ReadItem permission to analyze the currently selected message. It does not use that permission to browse unrelated mailbox items, modify or delete mail, or send mail on a user's behalf. The categories of information processed, purposes of processing, disclosures to subprocessors, security measures, retention periods, and available privacy rights are described in our Privacy Policy and Security & Trust page.

You represent that you have all rights and permissions necessary for MailBond to process data you submit to the Service. You must not submit data that you are prohibited from processing or disclosing under applicable law, contract, or organizational policy.

7. Acceptable Use

You may not, and may not permit another person to:

8. Third-Party Services

The Service interoperates with Microsoft services and uses carefully selected service providers to deliver specific functions. Third-party services are subject to their own terms and availability. MailBond is not responsible for third-party products or services that it does not control, but remains responsible for its own obligations regarding the Service and its handling of customer data. Current subprocessors and their purposes are identified on our Security & Trust page.

9. Ownership and Feedback

MailBond and its licensors retain all right, title, and interest in the Service, including its software, interfaces, documentation, designs, trademarks, and other intellectual property. You retain ownership of your data. If you provide suggestions or feedback, you grant MailBond a worldwide, perpetual, irrevocable, royalty-free right to use that feedback to improve and operate the Service without identifying you or your organization publicly.

10. Subscription, Fees, and Taxes

Subscription term, permitted user count, pricing, payment, renewal, and cancellation terms are stated in the applicable order, marketplace transaction, or separate customer agreement. You are responsible for applicable taxes except taxes based on MailBond's net income. Failure to pay amounts when due may result in suspension or termination after any notice or cure period required by the applicable order or law.

11. Updates and Changes to the Service

MailBond may provide updates, security patches, corrections, or feature changes. You agree that supported updates may be applied automatically. We may modify or discontinue features to address security, legal, technical, or business requirements, but will not materially reduce paid functionality during an active subscription term except when reasonably necessary for security, legal compliance, or third-party platform changes. Any Marketplace-specific preservation requirements applicable to existing users remain unaffected.

12. Availability and Support

We use commercially reasonable efforts to maintain the Service. The Service may be unavailable during maintenance, emergencies, internet or provider disruptions, or events outside our reasonable control. Unless a separate written service-level agreement applies, no specific uptime commitment is made. Technical and account support is available at admin@mailbond.us. Security issues may be reported to security@mailbond.us.

13. Security Results and User Responsibility

MailBond provides risk indicators and analysis, not a guarantee that a message, sender, link, website, attachment, QR code, or other content is safe or malicious. Threat intelligence can be incomplete, delayed, unavailable, or produce false positives or false negatives. You remain responsible for deciding whether to open, trust, respond to, download, or otherwise act on email content and for maintaining appropriate security controls, backups, policies, and incident-response procedures.

14. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." MAILBOND DISCLAIMS ALL EXPRESS, IMPLIED, AND STATUTORY WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR DETECT EVERY THREAT. NOTHING IN THIS AGREEMENT EXCLUDES A WARRANTY OR RIGHT THAT CANNOT LAWFULLY BE EXCLUDED.

15. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES, OR FOR LOST PROFITS, REVENUE, BUSINESS, GOODWILL, OR DATA, ARISING OUT OF OR RELATED TO THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF THOSE DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, MAILBOND'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THE SERVICE OR THIS AGREEMENT WILL NOT EXCEED THE AMOUNTS PAID OR PAYABLE FOR THE SERVICE BY THE APPLICABLE CUSTOMER DURING THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. IF THE SERVICE WAS PROVIDED WITHOUT CHARGE, MAILBOND'S TOTAL AGGREGATE LIABILITY WILL NOT EXCEED ONE HUNDRED U.S. DOLLARS (US $100). THESE LIMITATIONS DO NOT APPLY TO LIABILITY THAT CANNOT BE LIMITED UNDER APPLICABLE LAW.

16. Suspension and Termination

You may stop using and uninstall the Service at any time. MailBond may suspend or terminate access if you materially breach this Agreement, create a security or legal risk, fail to pay applicable fees, or if continued operation is prohibited by law or a third-party platform requirement. Where reasonable, MailBond will provide notice and an opportunity to cure. Upon termination, the license ends and you must stop using the Service. Provisions that by their nature should survive termination will survive, including ownership, disclaimers, liability limits, and general legal terms. Data handling after termination remains subject to our Privacy Policy and any applicable customer agreement.

17. Export and Legal Compliance

You must comply with applicable laws, including United States export controls, sanctions, privacy, communications, and computer misuse laws. You may not use or export the Service in violation of applicable restrictions or for prohibited end uses.

18. Indemnification

To the extent permitted by law, an organization using the Service will defend and indemnify MailBond against third-party claims arising from that organization's or its authorized users' unlawful use of the Service, violation of Section 7, or infringement caused by data submitted without the required rights or permissions. This obligation does not apply to the extent a claim is caused by MailBond's breach of this Agreement, negligence, or willful misconduct.

19. Governing Law and Disputes

This Agreement is governed by the laws of the State of California, without regard to conflict-of-law principles. The state and federal courts located in Ventura County, California will have exclusive jurisdiction over disputes arising from this Agreement, and each party consents to those courts. This section does not prevent either party from seeking urgent injunctive relief in a court of competent jurisdiction. Mandatory consumer-protection laws in your jurisdiction remain unaffected.

20. General Terms

This Agreement, the Privacy Policy, the applicable order, and any separate written customer agreement constitute the entire agreement concerning the Service. You may not assign this Agreement without MailBond's prior written consent, except as permitted by an applicable customer agreement. MailBond may assign it in connection with a merger, acquisition, corporate reorganization, or sale of substantially all relevant assets. Neither party is liable for delay or failure caused by events beyond its reasonable control, except for payment obligations. Failure to enforce a provision is not a waiver. If a provision is unenforceable, it will be enforced to the maximum lawful extent and the remaining provisions will continue in effect. Headings are for convenience only.

21. Changes to This Agreement

MailBond may update this Agreement to reflect changes in the Service, law, security requirements, or business practices. We will post the revised Agreement at this URL and update the date above. Material changes will apply prospectively and, when required, we will provide additional notice. Continued use after the revised terms take effect constitutes acceptance to the extent permitted by law.
