Terms of Service

Version 708e111923c4

The agreement between you and Blindrelay for use of the relay service.

1. The service

Blindrelay is a transactional email relay. We DKIM-sign and attempt SMTP delivery of messages you submit via the API, export delivery signals to your observability stack, and then discard message content. We do not store email body, subject, or headers at rest, except while a delivery that could not be completed immediately waits to be retried, for up to 24 hours. You can turn retries off for your workspace; message content then stays in memory and a temporary failure is final.

2. Business use and your account

Blindrelay is offered for use in your business or profession. By creating a workspace or buying a plan you confirm that you use Blindrelay for that purpose. Consumers may not buy paid plans; the Free plan is for evaluation.

You are responsible for activity under your account and API keys. Keep credentials secure. You must be authorized to enter this agreement and to send mail from the sending domains you configure.

3. Acceptable use

You must comply with our Acceptable Use Policy. It is incorporated into these Terms by reference. Violating it may result in suspension or termination without refund.

4. Plans, usage, and billing

Plans include a monthly message quota with overage billing and no daily send cap. Each accepted recipient counts as one message, and so does each message forwarded from your inbound aliases, if you set any up. Overage is billed until a hard stop, after which sends return an error and inbound forwards are retried for up to a day, then returned to the sender. Current prices are on the pricing page. The amount for your plan, including any VAT due for your billing country, is shown at checkout before you pay and applies to that billing period. Payments are processed by our payment provider.

5. Suspension and termination

We may suspend or terminate accounts that harm deliverability, violate the Acceptable Use Policy, expose us to legal liability, or abuse the service. Suspension may be automatic (based on complaint or bounce signals) or manual; a person reviews an automatic suspension on request. You may terminate at any time. On termination your workspace data is deleted as described in the Privacy Policy.

6. Your data and processing on your behalf

You are the controller of the personal data in the mail you send and receive through Blindrelay, and Blindrelay processes it for you as your processor. This section is the processing agreement between us under Article 28 of the General Data Protection Regulation; it applies to every plan for as long as your workspace exists. See also our Privacy Policy and the security overview. What we process for you:
  1. Subject matter and purpose: accepting, signing and delivering the messages you submit, forwarding mail received for your inbound aliases, keeping your suppression list, matching bounces, and reporting delivery events and statistics to you and to the endpoints you set up.
  2. Types of data: recipient addresses, the content of your messages, and delivery metadata such as status, time and recipient domain. Message content is held in memory during delivery. A message that must wait to be retried is kept on disk with its recipient address for up to 24 hours and then deleted, unless you turn retries off. Otherwise message content is never stored and recipient addresses are stored only as one-way hashes.
  3. Data subjects: the recipients of your messages, the senders of mail to your inbound aliases, and anyone named in message content.
  4. Duration: until your workspace is deleted, and afterwards only for the short periods stated in the Privacy Policy.
Our commitments:
  1. We process the data only on your documented instructions: these Terms, your workspace settings and your requests to the service. If the law requires other processing, we tell you first unless the law forbids it, and we tell you if we believe an instruction breaks the law.
  2. Everyone we authorise to process the data is bound by confidentiality.
  3. We keep appropriate technical and organisational security measures under Article 32, described in the security overview.
  4. You authorise the sub-processors named in the Privacy Policy. We tell you by e-mail before we add or replace one; you may object, and if we cannot resolve your objection you may end the service. We impose the same data protection obligations on each sub-processor.
  5. Taking into account what we can see (we cannot read back message content or recipient addresses), we help you answer data subjects' requests and meet your obligations under Articles 32 to 36.
  6. We notify you without undue delay after becoming aware of a personal data breach affecting your data.
  7. When your workspace is deleted, we delete your data; nothing remains to be returned, because message content is not stored.
  8. We give you the information needed to demonstrate these commitments and allow audits by you or an auditor you appoint, on reasonable notice.

7. No warranty

The service is provided "as is". We do not guarantee that any message will be delivered, accepted by a recipient mailbox provider, or pass spam filtering. Deliverability depends on factors outside our control, including your content and domain reputation.

8. Limitation of liability

To the maximum extent permitted by law, Blindrelay's aggregate liability for any claim is limited to the amount you paid in the twelve months preceding the claim. We are not liable for indirect or consequential damages. Nothing in these Terms limits liability that cannot be limited by law, such as for harm caused intentionally or through gross negligence, or the rights of consumers under mandatory law.

9. Changes

We may update these Terms. We notify the owners of each workspace of material changes by e-mail. Continued use after changes take effect constitutes acceptance. Every change to the wording is a new version of these Terms, and we keep a record of the version you accepted.

10. Governing law

These Terms are governed by Czech law, and the courts of the Czech Republic have jurisdiction.
