Anti-Spam Policy

Last updated 16 October 2026

MailMonster AI has zero tolerance for spam. This policy sets the rules for every email and text message sent through MailMonster AI, whoever sends it. It forms part of our Terms of Service. You are responsible for every message sent from your account, including by anyone you let use it.

1. Permission

  • Every recipient must have given clear, explicit and provable consent to receive your marketing messages, on the subject you send about.
  • Consent must be collected through a confirmed single or double opt-in. A sign-up checkbox must be unticked by default and must say what the person subscribes to.
  • For every address you must be able to show when, where and how consent was given. You send us that record within two business days when we ask.
  • Text messages need the same consent, given for text messages, to the phone number used.
  • Consent cannot be transferred. It covers only the brand and the subject the person signed up for.

2. Lists you may never use

  • Lists that were bought, rented, traded, shared or obtained from any third party, list partner or affiliate.
  • Addresses that were scraped, harvested, guessed, generated or appended from other data.
  • Addresses that unsubscribed, complained or were suppressed, wherever that happened.
  • We do not clean or validate a list that breaks these rules, and you may not ask us to.

3. What every email must carry

  • Accurate From, To and Reply-To headers that truly identify the sender and its domain. No forged or misleading headers, routing or IP information.
  • A subject line that honestly reflects the content.
  • The name of the sender and a valid physical postal address.
  • A link to the sender's privacy policy.
  • A clear unsubscribe link that anyone can recognise, plus one-click unsubscribe headers. MailMonster AI adds these headers to every email.
  • When an email is sent for a brand from a domain that is not the brand's own, the email says on whose behalf it is sent.

4. Opt-outs

An unsubscribe takes effect at once, and a customer can never reverse it. MailMonster AI stops sending to an address within seconds of an unsubscribe click and blocks permanently every address that hard-bounces. You may not email an address again after it opted out, through us or anyone else, unless the person subscribes again. Text messages can be stopped by replying STOP or through the opt-out link.

5. What you may never send

  • Anything that breaks a law, including laws on privacy, data protection, unsolicited commercial messages and consumer protection.
  • Content that is illegal, deceptive, fraudulent, defamatory, obscene, offensive or malicious, or that infringes anyone's rights.
  • Phishing, malware, or links to either.
  • Child sexual abuse material, any content that exploits people under 18, bestiality, or non-consensual sexual content.
  • Violence, threats, incitement, harassment or hate speech, or content that endangers safety, health or national security.
  • Chain letters, pyramid schemes, and get-rich-quick or other deceptive offers.
  • Gambling that is not licensed in every place where it is offered or seen, or that is sent to anyone under 18 or where it is not legal.
  • Sensitive personal data, such as health records, government identity numbers, or full card or bank account numbers.

6. Restricted industries

Affiliate marketing, payday loans and debt collection are sent only with our prior written approval. Before we approve, you give us specific guarantees and the consent record for every address. We may refuse any sender or offer we consider abusive or dishonest.

7. Delivery thresholds

We watch every campaign. When any of these limits is passed, we pause the sending and review it:

  • Bounces above 5% of the messages sent.
  • Unsubscribes above 1.4%, or above 1% when unsubscribes outnumber clicks.
  • Spam complaints above 0.08%.
  • Blocks by receiving servers of 20% or more.

We may change these limits at any time to protect deliverability.

8. Enforcement

We may monitor and audit your lists, consent records and messages at any time. If we believe this policy has been broken, we may throttle, pause or suspend your sending, suppress addresses, or end your account, without notice. You remain responsible for any costs, fines or claims your messages cause.

9. Report abuse

If you received a message through MailMonster AI that you did not ask for, write to hello@mailmonster.ai and include the full message with its headers. We investigate every report.
