Terms of Service

Last updated: 14 November 2026

1. Who we are

Djinnletter is a service of DJINN FOUNDRY, S.L., tax ID (NIF) B88711726, registered office at Plaza Julio Pardo 10, 46625 Cofrentes (Valencia), Spain. Write to us at founders@djinnfoundry.com.

These terms are the agreement between you and DJINN FOUNDRY, S.L. for the use of Djinnletter. Creating an account accepts them, together with the Acceptable Use Policy and the Privacy Policy.

2. The service

Djinnletter stores your audience, sends your newsletters and email sequences from your own domain, and reports what happened to them. You can use it from the dashboard, through the API, or through an AI agent you connect to it.

The service is meant for businesses and professionals.

3. Your account

• Give accurate information and keep your password and API keys to yourself.
• You are responsible for what is done with your account and your keys, including by an agent or a tool you connect.
• Tell us at once if you think someone else has access to your account.

4. What you may send

You may email only people who asked to receive email from you, and you must follow the Acceptable Use Policy. You are responsible for your content and for complying with the laws that apply to your email, such as the GDPR and the rules on commercial email in your country and your recipients' countries.

5. Credits and payment

• Sending is prepaid with credits. One credit sends one email. The price is shown before you pay, and taxes are added where they apply.
• Credits never expire.
• If you turn on automatic recharge, we charge your saved card when your balance runs low, for the amount you set. You can turn it off at any time.
• Credits cannot be exchanged for money, except where the law requires it or where we close your account without you having broken these terms. In that case we refund the credits you bought and did not use.
• If a payment is disputed or reversed, we may hold sending until it is settled.

6. Your data

Your content and your audience are yours. We use them only to provide the service.

For the personal data of your subscribers you are the controller and we are your processor. We process it only on your instructions, which are these terms and what you do in the service; keep it confidential and secure; use the providers named in the Privacy Policy, bound to the same duties; help you answer requests from the people concerned; tell you without delay about a breach that affects it; and delete it when you delete it or close your account, apart from what the law makes us keep.

You can export your audience at any time.

7. Availability and changes

We work to keep the service available and your email delivered, but we do not promise that it will never fail, and delivery to an inbox depends on mail providers we do not control. We may change or remove features; when a change takes away something you use, we tell you in advance.

8. Suspension and closing

• You can stop using the service and ask us to close your account at any time.
• We may pause sending or close an account that breaks these terms or the Acceptable Use Policy, that puts the delivery of other customers at risk, or where the law requires it. Unless the matter is urgent, we tell you first and give you the chance to fix it.

9. Liability

As far as the law allows, our total liability for any claim about the service is limited to what you paid us in the twelve months before the claim, and we are not liable for lost profit or indirect loss. Nothing in these terms limits liability that the law does not allow to be limited.

10. Law and courts

Spanish law governs these terms. Disputes go to the courts of Valencia, Spain, unless the law gives you the right to another court.

11. Changes to these terms

We may update these terms. When a change matters, we tell you by email or in the dashboard before it applies. The date at the top says when they last changed.
