Terms of Service
Last updated: 15 June 2026
These Terms of Service (“Terms”) are a binding agreement between you (“you” or “Customer”) and mittera, a service operated by flndrn (“mittera”, “we”, “us”), governing your access to and use of the mittera website at mittera.eu and the mittera email-sending platform, APIs, dashboards, and related services (together, the “Service”). By creating an account, accessing, or using the Service you agree to these Terms. If you do not agree, do not use the Service.
1. The Service
mittera is an email infrastructure platform that lets you send transactional and marketing email at scale through our API, SMTP relay, and dashboard. We may add, change, or remove features over time. Parts of the Service may be in beta or early development.
2. Accounts & eligibility
You must be at least 18 years old and able to form a binding contract to use the Service. You are responsible for the accuracy of your account information, for keeping your credentials and API keys secure, and for all activity that occurs under your account. Notify us promptly at admin@flndrn.com of any unauthorised use.
3. Acceptable use & anti-spam
Email is a shared resource, and our sending reputation protects every customer. You agree that you will not use the Service to:
- send unsolicited bulk email (spam) or email to recipients who have not consented to hear from you;
- send content that is unlawful, fraudulent, deceptive, infringing, harassing, or that distributes malware or phishing;
- omit a functioning unsubscribe mechanism in marketing email, or fail to honour opt-out requests promptly;
- falsify headers, sender identity, or routing information;
- violate applicable email and data laws, including the EU GDPR and ePrivacy rules and anti-spam laws such as CAN-SPAM and CASL.
You are solely responsible for obtaining lawful consent from your recipients and for maintaining accurate suppression lists. We may throttle, suspend, or terminate sending that harms deliverability or violates this section.
4. Fees & payment
Paid plans, where offered, are billed in advance and are described at the time of purchase. Unless stated otherwise, fees are exclusive of taxes, are non-refundable except where required by law, and usage above your plan’s included allowance may incur additional charges or require an upgrade. We will give reasonable notice of material price changes.
5. Your content & data
You retain all rights to the content you send and the recipient data you upload (“Customer Data”). You grant us a limited licence to process Customer Data solely to operate and provide the Service. With respect to personal data contained in the email you send, you act as the controller and mittera acts as your processor; our handling of that data is described in our Privacy Policy.
6. Intellectual property & open source
The mittera platform is open source and released under the GNU AGPL-3.0 licence; the governing licence text is in the LICENSE file of the source repository at codeberg.org/flndrn/mittera. Your use of the hosted Service is governed by these Terms. The mittera name and marks remain the property of flndrn.
7. Availability & changes
We work to keep the Service available and reliable but do not guarantee uninterrupted operation. We may perform maintenance, modify, or discontinue parts of the Service, and will use reasonable efforts to give advance notice of material changes.
8. Suspension & termination
You may stop using the Service and close your account at any time. We may suspend or terminate access if you breach these Terms, create risk or legal exposure for us or other customers, or harm deliverability. On termination your right to use the Service ends; you may export your data for a reasonable period unless prohibited by law.
9. Disclaimers
The Service is provided “as is” and “as available” without warranties of any kind, whether express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that any email will reach a recipient’s inbox, as delivery depends on factors outside our control.
10. Limitation of liability
To the maximum extent permitted by law, mittera and flndrn will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits or data. Our total aggregate liability arising out of or relating to the Service will not exceed the greater of the amounts you paid us in the three months before the claim or €100. Nothing in these Terms limits liability that cannot be limited by law.
11. Indemnification
You agree to indemnify and hold harmless mittera and flndrn from claims, damages, and costs arising out of your content, your use of the Service, or your breach of these Terms or of applicable law.
12. Governing law
These Terms are governed by the laws applicable to flndrn’s place of establishment, without regard to conflict-of-law rules, and the competent courts there will have exclusive jurisdiction, subject to any mandatory consumer protections in your country of residence.
13. Changes to these Terms
We may update these Terms from time to time. If we make material changes we will update the date above and, where appropriate, notify you. Your continued use of the Service after changes take effect constitutes acceptance.
