These Terms of Service govern access to and use of TETRUS AI and related TETRUS websites, dashboards, data, deliverability, and outbound workflow services operated by TETRUS Systems LLC ("TETRUS," "we," "us," or "our"), including tetrus.com, tetrus.ai, and related service domains. By creating an account, executing an Order Form, or using the Service, Customer agrees to these Terms.
Agreement: These Terms, any Order Form, Subscription Agreement, Data Processing Agreement, Acceptable Use Policy, Email Compliance Policy, and other incorporated policies.
Customer: The entity or individual that purchases, accesses, or uses the Service.
Service: TETRUS AI, including its websites, dashboards, APIs, software, lead intelligence, email workflow, deliverability tools, analytics, documentation, and related services.
Administrative Views: The Service may include platform-wide administrative views, customer-level administrative views, and per-customer Growth or Intelligence workspaces. Access to these views is controlled by permissions and account configuration.
Customer Data: Data, content, lists, contacts, records, messages, instructions, campaign materials, and other information submitted by or for Customer to the Service.
TETRUS Data: Data, models, templates, enrichment signals, deliverability logic, suppression systems, platform analytics, proprietary databases, and information developed, licensed, sourced, or maintained by TETRUS independently of Customer Data.

2.1 License
Subject to this Agreement and timely payment of fees, TETRUS grants Customer a limited, non-exclusive, non-transferable, non-sublicensable license to access and use the Service during the subscription term solely for Customer's internal business purposes.
2.2 Authorized Users
Customer is responsible for all Authorized Users and all activity under Customer's account, including campaign configuration, message content, list selection, sending instructions, and compliance decisions.
2.3 Restrictions
Customer may not use the Service to:
Resell, sublicense, rent, or make the Service available to any third party except Authorized Users.
Reverse engineer, decompile, disassemble, scrape, copy, or attempt to derive source code, models, databases, algorithms, scoring logic, or proprietary methods.
3.1 Orders and Subscription Term
Subscription plan, fees, term, usage limits, payment timing, renewal terms, and special commercial terms are stated in the applicable Order Form. Unless the Order Form says otherwise, subscriptions are prepaid and non-cancelable during the subscription term.
3.2 Payment and Taxes
Fees are due as stated in the Order Form and are payable in U.S. dollars. Customer is responsible for taxes, levies, duties, and similar government charges, excluding taxes based on TETRUS's net income.
3.3 Late Payment and Suspension
TETRUS may suspend or limit access if undisputed fees are more than fifteen (15) days past due after written notice. Suspension does not relieve Customer of payment obligations.
Customer is responsible for its business use of the Service. Customer represents and warrants that it has all rights, permissions, notices, consents, and lawful bases required to submit, process, target, contact, and use Customer Data and Prospect Data through the Service.
Customer is solely responsible for:
accuracy, legality, and appropriateness of Customer Data and campaign content;
products, services, claims, offers, pricing, guarantees, and statements contained in messages;
targeting criteria, prospect selection, sending instructions, and compliance settings;
using valid sender identities, domains, mailboxes, and physical mailing addresses where required;
honoring unsubscribe, objection, deletion, suppression, and no-contact requests;
complying with CAN-SPAM, CASL, GDPR, UK GDPR, PECR, CCPA/CPRA, state privacy laws, and other applicable laws.
TETRUS provides software, infrastructure, data, analysis, and workflow tools. Unless a separate written agreement expressly states otherwise, Customer is the advertiser, campaign owner, and primary sender or beneficiary of commercial outreach initiated for Customer's business. TETRUS may also be identified as a service provider, platform provider, technical sender, or other participant where required by law or operational configuration.
Customer must not use the Service to send misleading, deceptive, unlawful, or non-compliant commercial messages. Each commercial email must include accurate header information, non-deceptive subject lines, required sender identification, a valid physical postal address, and a clear unsubscribe mechanism. Customer must honor opt-outs promptly and must not re-upload or re-contact suppressed recipients.
TETRUS may suspend, throttle, block, or terminate campaigns, domains, accounts, or messages that TETRUS reasonably believes may violate law, harm deliverability, damage platform reputation, evade suppression controls, or create legal, security, or operational risk.
Messages may be routed through customer-approved domains, TETRUS-managed domains, mailboxes, subdomains, sending pools, and other then-current approved sending infrastructure and third-party providers as configured by TETRUS, depending on campaign configuration. TETRUS may add, remove, replace, or reconfigure sending domains, vendors, mailboxes, routing paths, verification gates, send-track rules, human approval steps, rate limits, suppression checks, and deliverability controls to protect compliance, security, deliverability, platform reputation, and service performance.
6.1 Customer Data Ownership
Customer retains ownership of Customer Data. Customer grants TETRUS a limited license to host, process, transmit, analyze, enrich, secure, support, and otherwise use Customer Data as necessary to provide, protect, and improve the Service and as otherwise permitted by this Agreement.
6.2 TETRUS Data and Platform Intelligence
TETRUS owns TETRUS Data, the Service, software, models, algorithms, databases, scoring logic, deliverability systems, templates, workflows, aggregated analytics, and all related intellectual property. TETRUS may use de-identified, aggregated, or statistical data to operate, secure, improve, and benchmark the Service, provided such data does not identify Customer as the source.
6.3 Data Protection Roles
For Customer Data submitted by Customer and processed only on Customer's documented instructions, TETRUS generally acts as processor/service provider and Customer acts as controller/business. For account administration, billing, security, platform operations, product improvement, compliance, fraud prevention, suppression lists, independently sourced or licensed data, TETRUS Data, and system-level deliverability or intelligence functions, TETRUS may act as an independent controller/business. The same data may be subject to different roles depending on the processing purpose. The DPA applies only where TETRUS processes personal data as processor/service provider for Customer.
6.4 Data Retention
After termination, Customer may request return or deletion of Customer Data. TETRUS will process verified deletion or return requests within a commercially reasonable period, subject to technical feasibility, backup cycles, legal obligations, security needs, dispute preservation, compliance obligations, and any different period stated in an Order Form. Customer should export Customer Data before termination. TETRUS may retain backup, security, audit, suppression, compliance, billing, abuse-prevention, and legal records as needed to operate the Service, prevent unlawful or unwanted sending, comply with law, resolve disputes, enforce agreements, and protect the platform. Suppression and no-contact records may be retained longer than ordinary account data because they are needed to prevent future re-contact.
Each party will protect the other party's confidential information using reasonable care and will use it only to perform under this Agreement. Confidentiality obligations do not apply to information that is publicly known without breach, independently developed without use of confidential information, lawfully received from a third party, or required to be disclosed by law after reasonable notice where legally permitted.
TETRUS owns all rights, title, and interest in and to the Service, TETRUS Data, software, algorithms, models, databases, designs, workflows, documentation, know-how, trademarks, service marks, trade names, logos, and related intellectual property. Customer may not use TETRUS names, marks, logos, screenshots, or branding without prior written consent, except to identify TETRUS as Customer's service provider in a truthful and non-misleading manner.
Customer grants TETRUS a limited right to use Customer's name and logo to identify Customer as a customer only if the applicable Order Form or written approval permits such use.
TETRUS will maintain commercially reasonable technical and organizational safeguards designed to protect Customer Data against unauthorized access, disclosure, alteration, and destruction. Customer is responsible for secure account administration, strong passwords, access control, authorized-user management, and lawful configuration of integrations, domains, and mailboxes.
This Agreement begins when Customer accepts it and continues through the subscription term. Unless an Order Form says otherwise, subscriptions renew for successive terms equal to the initial term unless either party gives at least thirty (30) days' notice of non-renewal before the current term ends. Either party may terminate for material breach if the breach is not cured within thirty (30) days after written notice. TETRUS may terminate or suspend immediately for nonpayment, unlawful use, security risk, abuse, or material violation of the Acceptable Use Policy or Email Compliance Policy.
Upon termination, Customer's right to use the Service ends immediately. Terms that by nature should survive will survive, including payment, confidentiality, intellectual property, data retention, disclaimers, indemnification, liability limits, dispute resolution, and compliance obligations.
Each party represents that it has authority to enter into this Agreement and will comply with applicable law in performing under this Agreement. TETRUS warrants that the Service will perform materially in accordance with its documentation. Customer's exclusive remedy for breach of this warranty is correction of the non-conforming Service or, if TETRUS cannot reasonably correct it, termination and a prorated refund of prepaid unused fees for the affected Service.
Except as expressly stated, the Service is provided "as is" and "as available." TETRUS disclaims all implied warranties, including merchantability, fitness for a particular purpose, non-infringement, accuracy, availability, deliverability, revenue results, sales outcomes, lead conversion, and uninterrupted or error-free operation. TETRUS does not guarantee that any data, lead score, AI output, deliverability signal, recommendation, enrichment result, or campaign outcome will be accurate, complete, current, lawful for Customer's use, or commercially successful.
To the maximum extent permitted by law, neither party will be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, lost goodwill, lost opportunities, business interruption, lost data, or cost of substitute services, even if advised of the possibility of such damages.
Each party's total cumulative liability arising out of or related to this Agreement will not exceed the greater of: (a) the fees paid or payable by Customer for the Service in the twelve (12) months before the event giving rise to the claim; or (b) $1,000. The liability cap does not limit Customer's payment obligations, either party's willful misconduct, Customer's misuse of the Service, Customer's indemnification obligations, or liability that cannot legally be limited.
Customer will defend, indemnify, and hold harmless TETRUS and its officers, directors, employees, contractors, agents, and affiliates from claims, damages, losses, liabilities, penalties, costs, and expenses, including reasonable attorneys' fees, arising from or related to Customer Data, campaign content, products or services promoted by Customer, Customer's use of the Service, Customer's violation of law, Customer's violation of third-party rights, Customer's sender identity or email compliance failures, or breach of this Agreement.
This Agreement is governed by the laws of the State of Delaware, without regard to conflict-of-law rules. Any dispute arising out of or relating to this Agreement will be resolved exclusively in the state or federal courts located in Delaware, and each party consents to personal jurisdiction and venue in those courts.
TETRUS may update these Terms, incorporated policies, legal pages, operational descriptions, vendor references, domain references, AI-provider references, subprocessor references, and platform-control descriptions from time to time. Material changes will be communicated with at least thirty (30) days' notice where required by law or by the applicable Agreement. Non-material operational changes, including changes to domains, subdomains, mailboxes, sending routes, infrastructure vendors, AI providers, security tools, suppression systems, verification tools, analytics tools, or administrative workflows, may be made without advance notice when TETRUS reasonably determines the change is operational, security-related, compliance-related, vendor-related, or does not materially reduce Customer's rights. Continued use after the effective date of a material change constitutes acceptance where permitted by law.
15.1 Platform Evolution
Customer acknowledges that TETRUS is an evolving software, data, email, deliverability, and AI-enabled platform. The Service may change over time, including features, dashboards, workflows, administrative views, data sources, email infrastructure, sending domains, vendors, AI systems, integrations, security measures, approval gates, suppression systems, enrichment logic, verification logic, and deliverability controls. TETRUS will not use operational flexibility to avoid material legal obligations, privacy obligations, or express contractual commitments, but may modify the platform in the ordinary course of business to improve, secure, scale, or comply with the Service.
