Anti-Spam Policy

Last updated: 2026-05-06

Mailmundo exists to help legitimate cleaning brands send email that recipients actually want. This Anti-Spam Policy defines our standards and the safeguards we run on every send.

1. Consent

You may only send marketing email to recipients who have given you affirmative consent to receive it. Acceptable consent methods include:

  • Web form opt-in with clear description of what you will send.
  • Double opt-in (required in EU, Germany, Austria; recommended elsewhere).
  • Existing customer relationship for transactional or service emails.

The following are NOT valid consent:

  • Pre-checked checkboxes.
  • Consent buried in unrelated terms.
  • Purchased, rented, or scraped lists.
  • Email addresses found via web scraping or LinkedIn export.
  • Implied consent because someone gave you a business card or attended a conference.

2. Required content for marketing email

  • Truthful sender name and FROM address.
  • Truthful, non-deceptive subject line.
  • Identification as commercial when applicable.
  • Valid physical postal address of the sender.
  • Clear, functioning unsubscribe link.
  • One-click unsubscribe via List-Unsubscribe-Post header (we add this automatically).

3. Suppression

Mailmundo automatically suppresses recipient addresses on:

  • Hard bounces (permanent delivery failure).
  • Complaints (spam button in recipient's mail client).
  • Unsubscribes (link, header, or reply parsed as opt-out).
  • Manual suppression entries you create.

Suppressed addresses are blocked across the project they were suppressed in. Removing a hard-bounce or complaint entry is not possible without auditable cause.

4. Engagement-based sunset

We automatically remove unengaged recipients (no opens or clicks in 90 days) from marketing audiences. This protects your sending reputation. Recipients can be re-engaged via opt-in campaigns.

5. Frequency capping

Default cap is 5 marketing emails per recipient per week. You can configure this per project. Transactional emails are not capped.

6. Authentication

We require SPF, DKIM, and DMARC for every sending domain. Emails failing alignment may be blocked. We support custom MAIL FROM, MTA-STS, TLS-RPT, and ARC.

7. Reporting spam

If you received unwanted email sent through Mailmundo, report it to abuse@mailmundo.com or via /abuse. We investigate every report and respond within 24 hours on business days.

8. Consequences of violation

Customers who violate this policy may be suspended or terminated. Severe violations are reported to relevant authorities (FTC, ANPD, ICO, CRTC, depending on jurisdiction) and to our upstream provider (AWS SES).
