Terms of Service
Effective date: July 19, 2026 · Last updated: July 19, 2026
These Terms of Service ("Terms") are a binding agreement between you and Extreme Results Technologies Inc. ("Extreme Results," "we," "us," or "our"), the company that provides Newsletter Engine AI ("the Service"). Newsletter Engine AI is a product and service of Extreme Results Technologies Inc.
1. Agreement and Acceptance
By creating an account or using the Service, you agree to these Terms. If you accept these Terms on behalf of an organization, you represent that you have the authority to bind that organization, and "you" refers to that organization as well as to you individually. If you do not have that authority, do not use the Service on behalf of an organization.
2. Eligibility
You must be at least 18 years old and have the legal capacity to enter into a binding contract to use the Service. You must not use the Service where doing so would be prohibited by applicable law. You agree to provide accurate registration information and to keep it up to date.
3. Account Registration and Security
You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. You must notify us promptly at support@newsletterengineai.com if you suspect unauthorized use of your account. Account sharing is not permitted unless your specific plan expressly supports multiple users. You must not impersonate another person or entity. We may suspend an account that appears to be compromised, without that suspension constituting a breach of these Terms.
4. Platform Description
Newsletter Engine AI provides AI-assisted editorial analysis, coaching, and rewriting for newsletters and similar written content, including Editorial Intelligence™ analysis, Editorial DNA™, the Living Writer Brain™, Generate V2™ rewrites, Editorial Strategy™, Knowledge Sources™, Research Intelligence™, Sessions™, and Markdown/PDF export. Features, their availability, and their exact behavior may change over time as we improve the Service.
5. Subscription Plans — Free Plan
The Free plan includes 3 Editorial Intelligence™ analyses and 2 Generate V2™ rewrites, basic Editorial Coaching, Markdown export, and community support. These limits do not reset automatically unless our pricing page specifically states that they do. We do not guarantee that the Free plan’s features or limits will remain unchanged indefinitely — we may change them prospectively, consistent with Section 29.
6. Subscription Plans — Pro Plan
The Pro plan is billed monthly or annually, in USD or BRL depending on the billing currency you select, at the rates displayed on the Pricing section of our website at the time of purchase — we do not restate specific prices here so this clause does not go stale when pricing changes. Annual billing includes a discount compared to paying monthly, as shown there. The price and currency shown at checkout control in the event of any discrepancy with marketing copy or this Section, and we take reasonable steps to keep marketing, checkout, and these Terms consistent. Applicable taxes may be added at checkout depending on your location. See Section 7 (Billing) for how price changes are handled for existing subscribers.
7. Billing
Paid subscriptions are billed on a recurring basis (monthly or annually, as selected) and renew automatically until canceled. By subscribing, you authorize us and our payment processor, Stripe, to charge your payment method on each billing date. If a payment fails, we or Stripe may retry the charge, and we may restrict access to paid features until payment succeeds. We may change our prices prospectively with reasonable advance notice; a price change will not apply retroactively to a period you have already paid for. Invoices are delivered electronically. All payments are processed by Stripe; see our Privacy Policy for how Stripe handles your payment data.
8. Cancellation
You may cancel your subscription at any time through your account’s billing settings (which use Stripe’s secure billing portal) or by contacting support@newsletterengineai.com. Canceling stops the next renewal; you retain access to paid features through the end of the billing period you have already paid for. Deleting your account is not automatically the same as canceling a subscription — if you have an active paid subscription, cancel it before or as part of closing your account to avoid being charged again. Cancel before your renewal date to avoid the next charge.
9. Refund Policy
Monthly and annual subscription fees are non-refundable once the applicable billing period has begun, except as described below or as required by applicable law. We do not provide refunds for partial billing periods, for features you did not use, or for failing to cancel before renewal, and account termination for a violation of these Terms does not entitle you to a refund. We will correct duplicate charges and confirmed billing errors. Initiating a chargeback with your card issuer does not replace or excuse you from following the process above, and we may dispute unwarranted chargebacks. Nothing in this Section limits any non-waivable statutory consumer right you may have under applicable law.
10. Free Trials and Promotions
If we offer a free trial or a promotional discount, its duration and terms will be disclosed at the time it is offered. A trial will convert automatically to a paid subscription only if we clearly disclose that in advance. Promotions are limited to one per eligible user unless stated otherwise, and we may revoke a promotion we determine, in good faith, to have been obtained through abuse of these Terms. We do not guarantee that any particular promotion will be offered again in the future.
11. User Content Ownership
You retain ownership of the content you submit to the Service. You grant us a limited license to host, process, reproduce, transform, and transmit your content solely to provide and improve the Service for you. We do not claim ownership of your newsletters or uploaded documents. You warrant that you have all rights and permissions necessary to upload your content, and you remain responsible for any personal data or third-party content it contains.
12. AI Output
AI-generated output — including analyses, scores, coaching recommendations, research suggestions, and Generate V2™ rewrites — may be inaccurate, incomplete, or may resemble content generated for other users, and is not guaranteed to be unique. Scores and recommendations are informational and are not a guarantee of quality, originality, legality, or non-infringement. You are responsible for reviewing and verifying all facts, citations, legal claims, and permissions before relying on or publishing any AI output, and you are solely responsible for the decision to publish. AI output does not replace professional editorial, legal, or compliance review, and you must not represent unverified AI-generated content as fact.
13. Intellectual Property
We and our licensors own all right, title, and interest in the Service’s software, source code, interfaces, algorithms, prompts, models, design system, documentation, and workflows. "Newsletter Engine AI," "Editorial Intelligence," "Editorial DNA," "Living Writer Brain," "Generate V2," "AI Workforce," and related names may be trademarks, service marks, or trade names of Extreme Results Technologies Inc.; we do not represent that any of these are federally registered unless we have separately confirmed that registration. You may not copy, modify, reverse engineer, or create derivative works from the Service except as expressly permitted by these Terms or by law.
14. Feedback
If you send us feedback, suggestions, or ideas about the Service, you grant us the right to use that feedback without payment, attribution, or other obligation to you. This does not give us rights to any unrelated confidential content you separately share with us.
15. Acceptable Use
You must not use the Service to: engage in unlawful activity, fraud, spam, or phishing; impersonate any person or entity; harass or discriminate against others; distribute malware; scrape or reverse engineer the Service; attempt credential attacks; circumvent usage limits or paywalls; engage in automated abuse; resell access to the Service without our authorization; infringe intellectual property or other rights; create deceptive content; attempt political manipulation or election interference; exploit or endanger minors; generate content prohibited by applicable law (including certain regulated categories); upload personal data without a lawful basis to do so; or violate the terms of any third-party platform, including Meta’s policies, in connection with your use of the Service.
16. Marketing and Advertising Compliance
If you use the Service in connection with your own marketing or advertising campaigns — including on Meta, Google, or any other platform — you agree to comply with that platform’s advertising standards and policies (including Meta’s Advertising Standards, Lead Ad Terms, and Custom Audiences Terms where applicable), to provide any required privacy notices and obtain any required consent from the people you target or contact, to maintain your own opt-out and suppression records, to avoid targeting minors where prohibited, to avoid using sensitive or prohibited data categories, not to sell any leads you collect, not to upload customer lists without the legal authority to do so, to honor opt-outs and suppressions you receive, and to comply with CAN-SPAM, the Telephone Consumer Protection Act (TCPA), GDPR, the ePrivacy Directive, the LGPD, and other applicable advertising and marketing laws. Newsletter Engine AI is not responsible for campaign rejection, account suspension, ad disapproval, delivery failure, a third-party platform’s policy changes, or your campaign’s performance.
17. Third-Party Services
The Service integrates with third-party providers, including Stripe (payments), OpenAI (AI processing), and Resend (email delivery); if we integrate with additional providers such as Meta or Google in the future, this Section will be updated. Each third-party provider has its own terms, which apply to your use of their services in connection with ours. Integrations may change or be discontinued, and we are not responsible for a third-party provider’s availability, performance, or policies. By using an integration, you authorize the transmission of the data necessary for it to function.
18. Beta and Experimental Features
We may offer features labeled beta, preview, or experimental. These are provided "as is," may be changed or discontinued at any time, may be less reliable than generally available features, and are not covered by any production-level guarantee. If we ask you to keep a beta feature confidential, additional confidentiality terms disclosed at that time will apply.
19. Service Availability
We do not guarantee uninterrupted or error-free access to the Service. We may perform maintenance, modify the Service, or apply usage or rate limits at any time. Because the Service depends on our AI provider, OpenAI, AI-dependent features may be unavailable or degraded if OpenAI’s own services are unavailable or degraded, and we are not responsible for that unavailability.
20. Suspension and Termination
We may suspend or terminate your access to the Service if you violate these Terms, present a security risk, fail to pay applicable fees, engage in fraud or abuse, or if we are required to do so by law or by a third-party platform requirement that affects the Service. Where reasonably practicable, we will provide notice and, where applicable, a limited window to export your data before final deletion, as described in Section 21.
21. Data Export and Account Closure
We recommend exporting any data you want to keep before closing your account. Export capabilities may vary by plan and feature (for example, Markdown and PDF export of individual analyses are currently available; an automated, account-wide data export tool is not yet available — contact support@newsletterengineai.com to request your data manually in the meantime). Deletion of your account is subject to the retention obligations described in our Privacy Policy; backups may retain your data for a limited period after deletion, and certain records may be retained for tax, fraud-prevention, dispute, or other legal purposes even after your account is closed.
22. Confidentiality
Each party agrees to protect the other party’s non-public confidential information disclosed in connection with the Service, using at least the same degree of care it uses to protect its own confidential information, and not to disclose it except to the extent required by law or reasonably necessary to perform its obligations. This Section describes the actual controls we apply and does not create enterprise-grade contractual confidentiality obligations beyond what is stated here, unless we have entered into a separate written agreement with you providing for that.
23. Disclaimers
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR AVAILABILITY. WE DO NOT WARRANT THAT THE SERVICE WILL MEET YOUR REQUIREMENTS, THAT AI OUTPUT WILL BE ACCURATE OR ORIGINAL, OR THAT USE OF THE SERVICE WILL RESULT IN ANY PARTICULAR PUBLICATION OUTCOME, OPEN RATE, CLICK RATE, CONVERSION, REVENUE, AUDIENCE GROWTH, RANKING, ENGAGEMENT, OR CAMPAIGN PERFORMANCE. NOTHING IN THIS SECTION LIMITS ANY CONSUMER RIGHT THAT APPLICABLE LAW DOES NOT PERMIT US TO DISCLAIM.
24. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, EXTREME RESULTS TECHNOLOGIES INC. WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, LOSS OF DATA, LOSS OF GOODWILL, LOST OPPORTUNITIES, OR LOSSES RELATED TO A CAMPAIGN OR PUBLICATION, ARISING FROM YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM ARISING FROM THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE FEES YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE, OR (B) US$100 FOR FREE-PLAN USERS. THIS LIMITATION APPLIES ONLY TO THE EXTENT PERMITTED BY APPLICABLE LAW. This liability cap is our current commercial position and, like the rest of these Terms, is subject to legal counsel review before final publication.
25. Indemnification
You agree to indemnify and hold harmless Extreme Results Technologies Inc. from claims, damages, and reasonable expenses arising from: your content; unlawful advertising or marketing campaigns you run in connection with the Service; your violation of applicable privacy law; your infringement of a third party’s intellectual property; your misuse of the Service; your violation of a third-party platform’s terms (including Meta’s); your unauthorized upload of personal data; or your noncompliance with Meta or other advertising-platform requirements. We will provide you reasonable notice of any such claim, and you will have the opportunity to participate in its defense; we retain the right to assume control of the defense of any claim that affects us.
26. Governing Law and Venue
These Terms are governed by the laws of the State of Florida, without regard to its conflict-of-laws principles. Any dispute arising from these Terms or the Service will be brought exclusively in the state or federal courts located in Miami-Dade County, Florida, and you consent to personal jurisdiction there. This Section does not waive any mandatory consumer-protection right you have under the law of your own country or state, including any non-waivable rights under EU consumer law or the LGPD, to the extent those rights cannot lawfully be waived by contract.
27. Export Controls and Sanctions
You may not use the Service if you are located in, or a resident of, a country or region subject to comprehensive U.S. sanctions, or if you are listed on any applicable denied-party or restricted-party list. You agree to comply with all applicable export control and sanctions laws in your use of the Service.
28. Copyright Complaints (DMCA)
If you believe content on the Service infringes your copyright, send a notice to support@newsletterengineai.com including: identification of the copyrighted work; identification of the allegedly infringing material and its location; your contact information; a statement of good-faith belief that the use is not authorized; a statement that the information in the notice is accurate and, under penalty of perjury, that you are authorized to act on the copyright owner’s behalf; and your signature. We have not yet designated a registered DMCA agent separate from this contact; the email above is our designated contact for copyright notices in the meantime. A user who receives a takedown notice may submit a counter-notice using the same contact and a comparable set of required statements.
29. Changes to These Terms
We may update these Terms from time to time. The "Last updated" date above reflects the most recent revision. We will provide reasonable notice of material changes by email or an in-product notice before they take effect. Your continued use of the Service after a change takes effect constitutes your acceptance of the updated Terms.
