Acceptable Use Policy

Last updated: 8 November 2026

Polpo Mail works because its servers are trusted by the rest of the internet. One sender's spam can get everyone's mail blocked, so we take this policy seriously. It is part of our Terms of Service.

1. No spam or bulk mail

• Do not send unsolicited commercial or bulk email, or any mail to people who haven't agreed to receive it.
• Do not use purchased, rented, scraped or harvested address lists.
• The Service is for person-to-person business email. Newsletters, marketing campaigns and large automated mailings belong on a dedicated bulk-email provider.
• Do not forge headers, hide the origin of messages, or use your account to relay other people's mail.

2. No harmful or illegal content

• No phishing, impersonation, fraud, scams or attempts to steal credentials or money.
• No malware, viruses or links to them.
• No content that is illegal where you or the recipient are, including child sexual abuse material, incitement to violence, harassment, threats, or infringement of others' intellectual property or privacy.

3. Respect the Service and other users

• Don't try to access accounts, mailboxes or data that aren't yours, or to get around authentication, quotas or rate limits.
• Don't probe, scan or load-test the Service without our written permission (good-faith security research is welcome under our disclosure policy).
• Don't register a domain you don't control, or create accounts in bulk.
• Don't resell the Service without our agreement.

4. Limits

To protect deliverability, each user may send to at most 500 external recipients per hour, and each message may be up to 25 MB. Exceeding limits causes messages to be deferred, not lost.

5. Enforcement

We may investigate suspected violations, including by reviewing message metadata and, where necessary to stop serious abuse, message content. Depending on severity we may warn you, throttle or block sending, suspend accounts or the whole workspace, and report illegal activity to the authorities. Where an account appears compromised, we may act first and contact you afterwards.

6. Reporting abuse

If you received spam, phishing or other abuse from a Polpo Mail address, please forward it with full headers to [email protected]. We review every report.
