LEGAL & COMPLIANCE DOCUMENTATION

Acceptable Use Policy (AUP)

Last updated: October 2, 2026 · Version 2.2 ·

Plain-English Summary: We protect our shared IP reputation so legitimate emails consistently hit the inbox.

1. Core Principles & Reputation Preservation

Centimailer maintains rigorous deliverability standards to protect shared and dedicated sending IP pools. High sender reputation ensures that legitimate cold outreach and newsletter campaigns achieve consistent inbox placement. Violations of this policy harm the collective infrastructure and are dealt with swiftly.

Plain-English Summary: Cold outreach is allowed if relevant to the recipient's role, with truthful headers and easy opt-outs.

2. Permitted Cold Outreach Standards

B2B outbound cold emailing is permitted on Centimailer only when adhering to the following ethical and legal criteria:

Relevance & Legitimate Interest: Messages must be targeted directly to business prospects with a clear, reasonable connection between your offer and the recipient's professional role.
Accurate Sender Identification: Senders must use truthful 'From' names and active, reply-monitored email addresses. Header manipulation and domain spoofing are strictly forbidden.
Clear Physical Address: Every commercial message must include a valid postal address or registered business entity identifier.
Accessible Unsubscribe Mechanism: Every message must include an active one-click opt-out link (using {{unsubscribe_url}}). Unsubscribe requests must be honored automatically without barrier or delay.

Plain-English Summary: Phishing, malware, get-rich-quick schemes, adult content, and illegal goods result in instant termination.

3. Strictly Prohibited Content & Verticals

The following categories of content are categorically banned from our platform. Any attempt to send emails containing the following will result in immediate permanent account termination:

Phishing, credential harvesting, social engineering, or fraudulent impersonation.
Malware distribution, spyware, ransomware, or links to deceptive or exploit-laden websites.
Predatory financial schemes, payday loans, get-rich-quick offers, multi-level marketing (MLM), or unregistered cryptocurrency investment solicitation.
Counterfeit products, unlicensed pharmaceuticals, prescription drug sales, or illicit substances.
Adult content, sexually explicit material, or escort services.
Hate speech, harassment, defamation, threats, or terroristic content.

Deliverability Thresholds: All workspace campaigns must maintain a hard bounce rate strictly below 5.0% and a spam complaint rate below 0.1% (no more than 1 complaint per 1,000 dispatches). Accounts exceeding these thresholds are automatically paused for deliverability review.

Plain-English Summary: No purchased, scraped, or unverified lists. Verify email addresses before uploading.

4. Audience List Sourcing & Hygiene

You may not upload purchased, scraped, rented, or harvested email lists from third-party lead brokers that have not undergone email verification. High bounce rates damage routing IPs and will result in sending queue locks. Senders are responsible for verifying list hygiene prior to importing contacts into Centimailer.

Plain-English Summary: Unsubscribed contacts are automatically suppressed. Never attempt to re-contact opted-out users.

5. Suppression List Enforcement

When a recipient clicks your unsubscribe link or submits an opt-out request, Centimailer records an automated suppression entry for your workspace. Attempting to circumvent suppression lists, re-upload suppressed addresses, or contact opted-out recipients is a direct violation of this policy.

6. Enforcement & Account Actions

Centimailer employs automated pattern detection and complaint monitoring. Violations result in the following progressive enforcement actions:

Level 1 (Warning & Throttling): Senders with elevated bounce rates will experience reduced batch dispatch speeds and receive list verification recommendations.
Level 2 (Queue Pause): Campaigns generating excessive complaints are paused pending compliance audit.
Level 3 (Permanent Termination): Severe intentional violations (such as phishing, fraud, or malware) result in immediate termination, IP banning, and complete forfeiture of remaining account balance.
