Acceptable Use Policy

This policy is part of the Terms of Service. It exists because the platform sends email in your name and shares delivery reputation across customers: one sender’s abuse lands in another customer’s spam folder.

1. Email and outreach

• Send only to people you have a lawful basis to contact. Purchased, scraped or rented lists are not allowed, and neither is importing a list you cannot explain the origin of.
• Honour opt-outs promptly. The product records them; ignoring the record is a breach of this policy and, in most places, of the law.
• Do not falsify sender identity, headers or reply addresses, and do not disguise who you are.
• Do not use the platform for phishing, malware distribution, or any message designed to deceive the recipient about who is writing.

2. Content and data

• No unlawful content, no content that infringes someone else’s rights, and no material that harasses or endangers a person.
• Do not load special categories of data the platform was not built for: health records, biometrics, government identity documents, payment card numbers, or anything covered by HIPAA or PCI DSS.
• Do not use the platform to build a product that competes with it, and do not resell access without a written agreement.

3. Technical limits

• Do not attempt to reach another workspace’s data, to bypass isolation or authentication, or to interfere with anyone else’s use of the service.
• Do not overload the API beyond published limits, and do not automate the interface to work around them.
• Security testing against your own workspace is welcome, and unwelcome anywhere else. Report what you find to [email protected]: we answer researchers, and we do not threaten them.

4. Enforcement

We would rather warn you than shut you down. For most breaches we contact you first and give you a chance to fix it. Where the abuse is severe, ongoing, or puts other customers at immediate risk — active phishing, malware, an attack on isolation — we suspend first and explain immediately after. Your ability to export your data survives any suspension. Report abuse to [email protected].
