Acceptable Use Policy

Last updated: 14 November 2026

Djinnletter sends newsletters and email sequences for its customers. Every customer shares the same sending infrastructure, so a sender who mails people who did not ask for it hurts everyone's delivery. These rules apply to every workspace and are part of the Terms of Service.

Who you may email

You may email a person only if that person asked to receive email from you, and you can show when and how they asked.

Not allowed:

• Lists you bought, rented, traded or received from a third party.
• Addresses collected from websites, directories, social networks or any other place where the person did not give them to you for this purpose.
• Addresses guessed, generated or added from another source without the person asking.
• People who unsubscribed, whose address bounced for good, or who marked your email as spam. Djinnletter stops mailing them and does not let you add them back. Only the person can return, by signing up again.

A signup through a Djinnletter form is confirmed by the person from their own inbox (double opt-in) before they receive anything.

What you may send

Not allowed:

• Email that hides or misstates who sends it, or a subject line that misleads about what is inside.
• Email without a working way to unsubscribe. Djinnletter adds an unsubscribe link and a one-click unsubscribe header to every email; do not hide or disable them.
• Phishing, malware or fraud.
• Content that is illegal where you are or where your recipients are.

What Djinnletter does

• An unsubscribe takes effect at once. A permanent bounce or a spam complaint removes the address from your audience for good.
• Each workspace sends from its own verified domain and has its own sending reputation. A workspace whose bounces or complaints show a problem is paused until it is reviewed.
• We may ask how a list was collected, pause sending, or close an account that breaks these rules. Credits spent on email sent in breach of them are not refunded.

Report abuse

If you received email sent through Djinnletter that you did not ask for, write to founders@djinnfoundry.com and include the email with its full headers. We look at every report.
