Maillayer

Acceptable Use Policy

Last updated November 12, 2026

Every Maillayer customer shares sending infrastructure and reputation. These rules keep email from all of us landing in the inbox. They apply to email sent from the dashboard, the API and AI agents alike.

Consent#

  • Only email people who asked to hear from you, or who have a clear, existing relationship with you (for example, customers getting receipts).
  • Don't use purchased, rented, scraped or shared lists, or addresses collected for a different purpose.
  • Be able to show when and how each contact agreed, if a recipient or mail provider asks.

Every marketing email must#

  • Say clearly who it's from, with an honest From name and subject line.
  • Include your postal address and a working unsubscribe link. Maillayer adds both to campaigns automatically; don't remove or hide them.
  • Honor unsubscribes. Maillayer suppresses them for you.

Not allowed#

  • Spam, cold email to purchased lists, or high-volume sending to people with no relationship to you.
  • Phishing, impersonation, spoofed senders, or anything designed to collect passwords or payment details deceptively.
  • Malware, or links to malicious or deceptive sites.
  • Illegal content or goods, and content that sexually exploits minors.
  • Harassment, threats, hate speech, or content that promotes violence.
  • Get-rich-quick schemes, pyramid schemes, and misleading financial, crypto or health claims.
  • Adult content, gambling, and pharmaceuticals, unless lawful where you and your recipients are and sent only to people who opted in.
  • Using shortened or hidden URLs to disguise where links go.
  • Trying to get around sending limits, suppressions, contact checks or account suspensions, including with multiple accounts.

Keep your lists healthy#

Keep bounces under 2% and spam complaints under 0.1%. Leave contact checks on, remove people who haven't engaged in a long time, and use domain warmup when you send to a large list from a new domain.

What happens if the rules are broken#

We watch bounce and complaint rates and review reports of abuse. Depending on the problem, we may warn you, slow or pause sending, or close the account, without notice when needed to protect recipients and other customers. See our Terms of Service.
