Terms of Service and
Acceptable Use Policy

These Terms of Service and Acceptable Use Policy ("Terms" or "Agreement") constitute the entire legal agreement between Mission Inbox Inc. ("Company," "we," "us," or "our"), a Delaware corporation, and you ("User," "Customer," "you," or "your") regarding your use of our email infrastructure platform, APIs, and all related services (collectively, the "Service").

By accessing, registering for, or using any part of the Service — including through any product line, API integration, or sub-account — you confirm that you have read, understood, and agree to be bound by these Terms. If you are entering into this Agreement 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, you may not access or use the Service.

Mission Inbox provides email delivery infrastructure designed for legitimate business communications. We operate two distinct product lines, each governed by separate acceptable use provisions within Section 4.

We maintain high deliverability standards through active management of our sending reputation, IP infrastructure, and enforcement of the quality standards in Section 4. Use of the Service constitutes your agreement to maintain those standards on your own sending activity.

Eligibility

• You must be at least 18 years old to use the Service.
• You must provide accurate, complete, and current registration information, including a valid business email address and billing details.
• You represent that you have full legal authority to enter into this Agreement, either individually or on behalf of the entity you represent.
• Accounts registered under false or fraudulent information are subject to immediate termination without refund.

Account Security

• You are solely responsible for maintaining the confidentiality of your account credentials, API keys, and any SMTP/IMAP credentials provisioned through the Service.
• You must notify us immediately at hey@missioninbox.com upon discovering any unauthorized access to your account or credentials.
• You are liable for all activity — including all sends and usage charges — that occurs under your account, whether authorized by you or not, until you notify us of unauthorized access and we confirm remediation.
• You may not share account access, API keys, or provisioned credentials with third parties not authorized under your account without our prior written consent.

Account Termination by Mission Inbox

We reserve the right to suspend or terminate your account immediately, with or without notice, for:

• Violation of any provision of these Terms or the Acceptable Use Policy.
• Fraudulent, deceptive, or illegal activity conducted through the Service.
• Failure to pay applicable subscription or usage fees as described in the Billing Policy.
• Activity that materially harms our sending reputation, IP pool health, or deliverability for other customers.
• Exceeding the deliverability thresholds defined in Section 4 without remediation.

Product-Line Philosophy

Mission Inbox operates on a quality over quantity principle. We support legitimate business communications — including high-volume cold outbound when done properly — and actively prohibit spam, abuse, and misuse that degrades deliverability for all customers. The standards below apply to both product lines, with additional provisions specific to each.

4.1 — Deliverability Requirements (Both Product Lines)

All accounts must maintain the following thresholds at all times. Exceeding any threshold may result in immediate account suspension pending review:

4.2 — Sales & Marketing: Permitted Use

The Sales & Marketing product line is designed exclusively for business-to-business (B2B) outreach. The following standards apply:

• B2B only: Sends must target business email addresses. Consumer or personal email addresses (Gmail, Yahoo, Hotmail, etc.) used for personal purposes are not permitted targets for cold outreach.
• Personalization required: Emails must be individually relevant to the recipient's business role, company, or function. Mass, non-personalized blasts are prohibited.
• Sender identification: All emails must include accurate sender name, company name, and a valid physical address.
• Opt-out mechanism: All outbound emails must contain a clear, functional, and immediately honored opt-out or unsubscribe mechanism.
• Reasonable volume: Send volumes must be proportionate to your mailbox count and warm-up status. Blasting unwarmed mailboxes is a Terms violation.
• Regulatory compliance: You are solely responsible for compliance with CAN-SPAM, GDPR, CASL, and all other applicable regulations in the jurisdictions you send to.

4.3 — Transactional: Permitted Use

The Transactional product line is intended for system-generated, event-triggered emails to recipients who have an established relationship with your product or service:

• Triggered by user action: Transactional emails must be sent in response to a specific user action (account creation, purchase, password reset, etc.) or a time-based system event tied to an existing user relationship.
• No marketing content: Transactional emails must not contain primary marketing or promotional content. Incidental product mentions are permitted where the core message is transactional.
• Opt-in recipients only: Recipients must have an established relationship with your product or service. Unsolicited transactional-style emails to cold lists are prohibited.
• Accurate sender information: From name, reply-to address, and subject lines must accurately identify the sending entity and the nature of the message.

4.4 — Strictly Prohibited (Both Product Lines)

4.5 — Technical Restrictions

• No attempting to circumvent rate limits, sending quotas, or platform-enforced warm-up schedules.
• No creating multiple accounts to evade restrictions, suspensions, or bans. Re-registration after termination is prohibited without our prior written consent.
• No interfering with platform operations, infrastructure, or other customers' service.
• No reverse engineering, decompiling, or attempting unauthorized access to Mission Inbox systems.
• No using the Service as a relay, proxy, or anonymization layer for third-party senders not authorized under your account.

All billing terms, pricing, usage definitions, refund conditions, dispute procedures, and payment obligations are governed by the Mission Inbox Billing Policy, which is incorporated into these Terms by reference and forms part of this Agreement.

The following is a non-exhaustive summary of key billing principles. The Billing Policy is authoritative in all cases:

Mission Inbox provisions and stores SMTP/IMAP credentials on your behalf, and provides API access to platform features. This section governs your obligations with respect to those credentials and API usage.

Your Credential Obligations

• Security responsibility: You are responsible for the secure storage and handling of all API keys, SMTP credentials, and IMAP credentials provided to or provisioned by Mission Inbox. Do not embed credentials in client-side code, public repositories, or shared documents.
• Authorized use only: Credentials may only be used by systems and personnel authorized under your account. You may not share, sublicense, or resell credential access to third parties without our prior written consent.
• Immediate revocation on breach: If you believe any credential has been compromised, you must notify us immediately at hey@missioninbox.com and rotate the affected credential. Mission Inbox will assist with revocation upon request.
• Termination revocation: Upon account termination for any reason, all credentials provisioned through the Service are immediately revoked. You must cease use and delete all stored copies. Continued use of revoked credentials is unauthorized access.

Third-Party Platform Integrations

• If you integrate Mission Inbox with a third-party platform, tool, or service, you are responsible for ensuring that third party complies with these Terms with respect to its use of your Mission Inbox credentials.
• You may not authorize a third party to use Mission Inbox infrastructure if that third party's own operations would violate these Terms. You are liable for violations by authorized third parties as if you had committed them directly.
• Mission Inbox may revoke access to any integration determined to be operating outside the scope of these Terms, without prior notice to you.
• You must disclose upon request the identity of any third-party platforms or services that have access to your Mission Inbox credentials or infrastructure.

API Rate Limits & Fair Use

• API usage is subject to rate limits defined in our platform documentation. Limits may be adjusted at any time with reasonable notice.
• Automated systems must identify themselves accurately and may not attempt to mask API calls as human interactions.
• Sustained API usage that materially degrades platform performance for other customers constitutes an abuse violation regardless of whether individual rate limits are formally exceeded.

Data We Process on Your Behalf

In the course of providing the Service, Mission Inbox processes the following categories of data on your behalf:

Security Standards

• Mission Inbox operates under an active SOC 2 compliance program. Controls cover access management, encryption in transit and at rest, incident response, and change management.
• SMTP/IMAP credentials stored in our platform are encrypted at rest using industry-standard encryption. Credentials are never exposed in logs, error messages, or support interfaces.
• Access to customer data is restricted to Mission Inbox personnel who require it to provide or support the Service. We do not sell customer data to third parties.
• In the event of a confirmed security incident affecting your account data, we will notify you within 72 hours of discovery via the email address on your account.

Data Deletion on Termination

• Upon account termination, your account data is retained for 30 days to allow for dispute resolution and final billing, then purged from active systems.
• You may request accelerated deletion of account data by submitting a written request to hey@missioninbox.com. Deletion requests do not affect our obligation to retain data required by law or for active dispute resolution.
• Billing records and usage logs may be retained for up to 7 years for tax and legal compliance purposes.

Your Data Obligations

• You are the data controller for all recipient data you send through the Service. Mission Inbox acts as a data processor on your behalf.
• You warrant that you have a lawful basis for processing all recipient data you introduce into the Service, including consent where required by applicable law.
• You are responsible for complying with data subject access, correction, and deletion requests under GDPR, CCPA, and other applicable privacy laws with respect to data you control.

Uptime Commitment

Mission Inbox targets 99.5% monthly uptime for core sending infrastructure across both product lines. Uptime is calculated as the percentage of minutes in a calendar month during which the sending API and SMTP relay are operational, excluding scheduled maintenance.

SLA Exclusions

The uptime commitment and any associated credits do not apply to downtime or degradation caused by:

• Scheduled maintenance windows communicated at least 24 hours in advance.
• Customer-side issues including invalid credentials, misconfigured integrations, or customer-initiated API abuse.
• Third-party provider outages outside Mission Inbox's reasonable control (upstream ISPs, DNS providers, cloud infrastructure).
• Deliverability degradation caused by the customer's own sending behavior or AUP violations.
• Force majeure events including natural disasters, government actions, or cyberattacks.
• Accounts in suspension or under active review for policy violations.

How to Claim a Service Credit

• Submit a credit request to hey@missioninbox.com within 14 calendar days of the incident.
• Include the date, time range, and nature of the reported downtime. We will verify against our infrastructure logs.
• Approved credits are applied to your next invoice. Credits are not redeemable for cash and are forfeited upon account termination.
• Service credits are your sole remedy for service unavailability. Mission Inbox is not liable for any indirect or consequential losses resulting from downtime.

Your Content

• You retain full ownership of all email content, recipient lists, and data you submit through the Service.
• You grant Mission Inbox a limited, non-exclusive license to transmit, deliver, store, and process your content solely as necessary to provide the Service.
• You are solely responsible for the legality, accuracy, and appropriateness of all content you send through the Service.
• You warrant that you have all necessary rights, licenses, and consents for all content and recipient data you introduce into the Service.

Mission Inbox Intellectual Property

• The Service, platform, APIs, AI Shield technology, deliverability infrastructure, and all original content remain the exclusive property of Mission Inbox Inc.
• Mission Inbox trademarks, logos, and brand assets may not be used without prior written consent.

Copyright Infringement

Our data handling practices are detailed in our Privacy Policy, which is incorporated into these Terms by reference. By using the Service, you consent to our collection and use of information as described in the Privacy Policy.

For data processing activities where Mission Inbox acts as a processor on your behalf (handling of recipient email addresses and content), the terms in Section 7 of these Terms of Service apply. For data where Mission Inbox acts as a controller (your account data, billing information), the Privacy Policy governs.

Enterprise customers requiring a formal Data Processing Agreement (DPA) for GDPR compliance should contact hey@missioninbox.com.

• Mission Inbox may modify, update, add, or discontinue features and product lines at any time. Material changes to core functionality will be communicated with at least 14 days' notice where practicable.
• We may update these Terms by posting a revised version on our website. We will notify you of material changes via email to your registered address. Continued use of the Service after the effective date of any revision constitutes acceptance.
• Pricing changes are governed by the notice provisions in the Billing Policy.
• Scheduled maintenance will be communicated in advance when possible. Emergency maintenance required to protect infrastructure integrity may be performed without advance notice.

Monitoring

Mission Inbox uses automated systems to monitor sending activity, complaint rates, bounce rates, and API usage for compliance with these Terms. Automated monitoring may trigger account flags, warnings, or suspensions. We may also conduct manual review of flagged accounts at any time.

Violation Response

Depending on the nature and severity of a violation, our response may include:

• Warning: Written notice with a defined remediation window. Appropriate for first-time, low-severity threshold breaches.
• Temporary suspension: Sending disabled pending investigation or remediation confirmation. Account data and billing obligations remain active.
• Permanent termination: For severe, repeated, or intentional violations. Final usage invoice is generated and collected. Re-registration is prohibited.
• Legal action: For violations involving fraud, unauthorized access, or harm to third parties, we reserve the right to pursue civil and criminal remedies.

Appeals

• Suspended accounts may appeal by emailing hey@missioninbox.com with subject line "Account Suspension Appeal" within 10 business days of suspension notice.
• Appeals will be reviewed within 5 business days. We will notify you of the outcome in writing.
• Decisions made upon completion of the appeals process are final.

Service Warranty Disclaimer

Deliverability Disclaimer

Mission Inbox provides infrastructure for email delivery. We do not guarantee inbox placement, open rates, or deliverability outcomes. Deliverability is influenced by factors outside our control including recipient mail server policies, sender reputation established by your sending behavior, and third-party blocklists. Failure to achieve desired deliverability outcomes does not constitute a service failure or grounds for refund.

Limitation of Liability

Indemnification

You agree to defend, indemnify, and hold Mission Inbox Inc., its officers, directors, employees, agents, and successors harmless from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to: (a) your use of the Service; (b) your violation of these Terms; (c) your violation of any applicable law or regulation; (d) your email content or recipient data; or (e) any claim by a third party that your use of the Service violated their rights.

Governing Law

These Terms are governed by and construed in accordance with the laws of the State of Delaware, United States of America, without regard to its conflict of law principles.

Dispute Resolution

Any dispute, claim, or controversy arising out of or relating to these Terms or the Service that is not first resolved through Mission Inbox's internal billing dispute process (as described in the Billing Policy) shall be resolved by binding arbitration administered in Delaware, United States of America. The arbitration shall be conducted on an individual basis. You waive any right to participate in a class action lawsuit or class-wide arbitration against Mission Inbox. Claims eligible for small claims court may be filed there instead of arbitration.

Entire Agreement

These Terms, together with the Billing Policy and Privacy Policy incorporated herein by reference, constitute the entire agreement between you and Mission Inbox regarding the Service and supersede all prior agreements, understandings, negotiations, and representations, whether written or oral, relating to the subject matter herein. Enterprise customers with a separately executed Master Service Agreement (MSA) are governed by the MSA to the extent it conflicts with these Terms.

Severability

If any provision of these Terms is found by a court of competent jurisdiction to be invalid, illegal, or unenforceable, that provision shall be modified to the minimum extent necessary to make it enforceable, and the remaining provisions shall continue in full force and effect.

Waiver

Mission Inbox's failure to enforce any right or provision of these Terms shall not constitute a waiver of that right or provision. No waiver of any breach shall be deemed a waiver of any subsequent breach.

Assignment

You may not assign or transfer your rights or obligations under these Terms without our prior written consent. Mission Inbox may assign these Terms without restriction in connection with a merger, acquisition, or sale of substantially all of its assets. These Terms bind and inure to the benefit of each party's permitted successors and assigns.

Force Majeure

Neither party shall be liable for delays or failures in performance resulting from circumstances beyond its reasonable control, including but not limited to natural disasters, acts of government, pandemics, network infrastructure failures, or cyberattacks. The affected party shall notify the other promptly and use reasonable efforts to mitigate the impact.
