Acceptable Use and Anti-Spam Policy

Effective and last updated: July 17, 2026

terriblemail is for legitimate, permission-based programmatic email. You may not use it to send spam, deceive recipients, compromise systems, or damage shared email reputation.

Consent and sender responsibility

You must have a lawful basis and any consent required to contact each recipient. You must accurately identify the sender, honor opt-outs, maintain suppression lists where required, and comply with laws and industry rules that apply to your messages, including commercial-email, privacy, consumer-protection, and telecommunications requirements.

Marketing email is permitted only to recipients with valid, documented permission and must include accurate sender information and a functional unsubscribe method when required. Purchased, scraped, harvested, or guessed address lists are prohibited.

Prohibited activity

You may not use terriblemail to:

• Send unsolicited bulk or commercial email, spam, list-washing, or snowshoe campaigns.
• Send phishing, credential-theft, malware, ransomware, fraudulent, deceptive, or materially misleading content.
• Impersonate another person or organization, spoof an identity without authorization, or conceal the origin of a message.
• Harass, threaten, exploit, discriminate against, or unlawfully monitor another person.
• Distribute illegal content or facilitate illegal goods, services, access, or activity.
• Send content that violates intellectual-property, privacy, publicity, confidentiality, or other rights.
• Probe, overload, bypass, reverse engineer, or interfere with the service, quotas, security controls, suppression controls, or provider restrictions.
• Create accounts or rotate domains, recipients, IPs, or credentials to evade enforcement.
• Use programmatic inboxes to collect stolen credentials, intercept communications without authority, or support fraud.

Automation and AI agents

You remain responsible for messages initiated by scripts, agents, models, integrations, and users acting through your account. Use appropriate human approval for consequential, sensitive, financial, legal, medical, employment, or high-volume messages. Protect API keys, constrain tools, test recipient selection, and implement safeguards against prompt injection and unintended sends.

Quality requirements

You must keep bounce and complaint rates low, stop sending to invalid or objecting recipients, and promptly investigate unusual activity. We may impose tighter limits, require evidence of consent, disable sending or receiving, suppress recipients, or request remediation to protect recipients and shared infrastructure.

Enforcement

We may investigate suspected violations and preserve or disclose relevant evidence as permitted by the Privacy Policy and law. Depending on severity, we may warn, throttle, block messages, suspend, or terminate accounts immediately. Serious abuse may be reported to infrastructure providers or authorities.

Report abuse

Report suspected abuse to help@terrible.llc. Include relevant sender and recipient addresses, timestamps, full headers, and the reason for the report. Do not include passwords or payment credentials.
