1. Permission and lists
- Send only to people who have an existing relationship with you and expect your email (transactional mail), or who have explicitly opted in (bulk or marketing mail).
- Never use purchased, rented, harvested, scraped, co-registration or "opt-out" lists, and never send to role addresses (such as abuse@ or postmaster@) you did not collect directly.
- Keep proof of consent and be able to show it on request.
- Do not email addresses that unsubscribed, bounced permanently or complained.
2. Message requirements
- Use accurate From, Reply-To and subject lines; never impersonate another person, brand or organisation.
- Send from domains you own or are authorised to use and have verified with us.
- Bulk and marketing email must include a working one-click unsubscribe (List-Unsubscribe and List-Unsubscribe-Post headers), a visible unsubscribe link and your postal address where the law requires it, and must use the broadcast stream.
- Do not send marketing content through the transactional stream.
3. Prohibited content and activity
You may not use the service to send or facilitate:
- phishing, credential harvesting, malware, or links to them;
- fraud, scams, deceptive offers, pyramid schemes or fake invoices;
- illegal content or goods, or content that infringes others' intellectual property or privacy;
- child sexual abuse material (reported to authorities), sexually explicit content, or content promoting violence, hate or harassment;
- unlicensed gambling, unregulated financial or crypto investment offers, debt relief, payday loans, or unapproved pharmaceuticals and supplements;
- "get rich quick", adult dating, or affiliate marketing to recipients who did not opt in to that specific sender;
- attempts to probe, overload or bypass limits of the service, share credentials with third parties, or resell the service without our written agreement.
4. Bounce and complaint thresholds
To protect deliverability for everyone, accounts are reviewed and may be paused automatically when they exceed:
| Signal | Threshold |
|---|---|
| Hard bounce rate | above 5% of delivered messages |
| Spam complaint rate | above 0.1% (and well below 0.3%, Gmail's published limit) |
| Spam traps or blocklist listings | any, depending on severity |
5. Enforcement
We monitor sending for abuse signals and scan outbound mail for spam and malware. Depending on severity we may warn you, lower your limits, pause sending, require changes, or suspend or terminate your account, in serious cases without notice. Fees are not refunded for accounts terminated for violating this policy.
To report abuse sent through MailerAce, forward the message with full headers to [email protected].
