Acceptable Use Policy

Effective October 23, 2026.

This policy applies to everyone who uses Breaker's services, including the app, email sending, automations, web publishing, custom domains, the API and MCP server, and any feature we add later. It covers all content you upload, send, publish or process through Breaker ("Content"). It is part of the Breaker Terms of Service. Breaker may investigate, remove Content, pause sending, restrict features, or suspend or terminate accounts for violations, and for any conduct that creates legal, security, reputational or deliverability risk to Breaker, its customers or recipients, even if it is not listed here. Report abuse to report@joinbreaker.ai.

1. Email: consent, lists and sending

Consent. Send only to people who have given you affirmative consent to receive your email, or whom you have another lawful basis to contact under the laws that apply to you and to them (including CAN-SPAM, CASL, GDPR and the ePrivacy Directive, UK GDPR, and CCPA). Consent must be freely given, specific and informed, and given by a clear action such as filling in a signup form or ticking an unticked box.

Lists that are never acceptable. Purchased lists, even if sold as "opt-in". Rented or co-registration lists. Addresses scraped or harvested from websites, social networks, directories or public sources. Lists supplied by partners, affiliates or lead-generation networks. Addresses collected under a blanket consent that did not name you as a sender. Addresses from business cards or event badge scans without a separate opt-in.

Proof of consent. Keep a record of how and when each contact consented: source, date, method, and the form or page used. Breaker may ask for it, and may pause sending until you provide it.

Unsubscribes. Every email must carry the unsubscribe link Breaker inserts. Do not remove, hide, delay or alter it. Opt-outs are processed automatically and must be honored for every list and automation in your account. Do not re-add anyone who unsubscribed, complained or withdrew consent, on Breaker or any other platform, without a new and specific opt-in. Do not import a list to Breaker in order to get around suppression on another platform.

Sender identification. Every email must include your valid physical postal address. From names, reply-to addresses, subject lines and headers must be accurate and must not impersonate anyone. Subject lines designed only to trick a recipient into opening ("Re:" on a first contact, fake invoices, fake replies) are prohibited.

Sending quality. Breaker monitors bounce, complaint and unsubscribe rates per account and per domain. Accounts above 2% hard bounces or 0.1% spam complaints on a send, or whose rates Breaker considers abnormal, may be paused for review. Repeated or severe complaints may result in termination without refund. The following are prohibited: list washing (using Breaker to test or clean a list by observing bounces or welcome-email results), snowshoeing (spreading sends across accounts, domains or newsletters to evade reputation limits), and repeatedly deleting and re-importing contacts.

Automations. Messages sent by automations are your messages. Test automations before enabling them, keep their consent basis current, and pause them when they should no longer run. Automations that re-engage contacts who have not interacted in 12 months must use a confirmed re-opt-in step before resuming regular sends.

2. Prohibited content

Do not upload, send or publish Content that:

• Is illegal, or promotes or facilitates illegal activity, violence, terrorism, human trafficking or exploitation.
• Sexualizes or endangers minors. Zero tolerance: accounts are terminated immediately and reported to NCMEC and law enforcement.
• Promotes hatred, discrimination or violence against people based on race, ethnicity, national origin, religion, sex, gender identity, sexual orientation, disability, age or similar characteristics.
• Harasses, threatens, bullies, doxxes or stalks any person, or coordinates others to do so.
• Is sexually explicit or pornographic, or promotes escort, adult-webcam or similar services.
• Promotes self-harm, suicide or eating disorders other than in a supportive or educational way.
• Is fraudulent, deceptive or misleading, including phishing, fake invoices, impersonation of a person, brand or government body, deceptive landing pages, fake reviews or testimonials, and "guaranteed results" claims.
• Infringes copyright, trademark, trade secret, privacy, publicity or other rights.
• Contains malware, forced downloads, injected scripts or deceptive redirects.
• Is AI-generated or manipulated media intended to deceive, including non-consensual deepfakes and synthetic impersonation. Clearly disclosed AI assistance in your own voice is fine.
• Collects, stores or transmits sensitive personal data through Breaker: government ID numbers, payment card numbers, bank credentials, health records, or precise geolocation. Breaker is not designed to hold these.

3. Restricted industries and content

The following are prohibited, or permitted only on the stated conditions. Breaker may ask for evidence of compliance and may decline any account in these categories at its discretion.

4. Web publishing and custom domains

• Hosted pages are for your publication: newsletter archives, landing pages, signup pages and related content. Not for file distribution, software downloads, backups, or hosting assets for other sites.
• Pages whose main purpose is to redirect visitors, manipulate search engines (link farms, cloaking, hidden text, keyword stuffing) or harvest data are prohibited.
• Adult, age-gated or geo-restricted material is not supported on hosted pages.
• Published Content must follow sections 2 and 3 of this policy. Breaker may unpublish pages that do not.
• Connect only domains you own or are authorized to use. Keep the DNS records Breaker requires in place. Do not connect a domain to impersonate another organization, and do not rotate domains to evade sending restrictions.

5. API, MCP server and AI clients

• Use the API and MCP server only for your own account, through documented interfaces, within published rate limits. Do not attempt to bypass limits or scopes.
• API keys and OAuth grants are yours to protect. Do not share them, embed them in public code, or use them on behalf of a third party without written permission from Breaker.
• Everything an AI client does through your connection is your action. Review drafts before you send, and do not connect an agent that updates contacts or segments without a person reviewing the result.
• Do not use the developer tools to scrape, extract or copy data beyond your own account, to test Breaker's security without written approval from security@joinbreaker.ai, or to build a product that replaces or interferes with the Services.

6. Platform and account integrity

• No unauthorized access, probing, vulnerability scanning or denial-of-service against Breaker or other customers.
• No fake accounts, no selling or transferring accounts, and no creating multiple accounts or newsletters to get around billing, limits or a suspension.
• No inflating or falsifying engagement, including self-clicks, click farms or scripts that simulate opens and clicks, and no misrepresenting subscriber counts or engagement to advertisers or sponsors.
• No payment or chargeback fraud.
• No use by or on behalf of anyone on a U.S., EU, UK or UN sanctions list, or from a comprehensively sanctioned jurisdiction.

7. Enforcement

Breaker may act on a violation in any proportionate way: a warning, removal of Content, pausing a send or automation, rate limits, disabling a feature or domain, suspension, or termination. Breaker will usually notify you by email and give you a chance to fix the problem, but may act first without notice where there is a risk to recipients, other customers, deliverability or Breaker, or where the law requires it. Fees are not refunded for accounts terminated under this policy. Breaker may cooperate with law enforcement, mailbox providers and anti-abuse organizations, and may preserve and disclose account information where required by law.

To appeal an enforcement action, reply to the notice email within 14 days. To report abuse, email report@joinbreaker.ai with the message or page in question.
