Privacy Notice
This notice explains the categories of data Postline may process and the controls available to customers.
Data categories
- Account and technical-contact details
- Sending domains and configuration
- Recipient addresses and delivery metadata
- Message content only when enabled or required for delivery
- API, authentication, audit, abuse, and webhook logs
Operator and legal basis
The Postline service and account data controller is Individual Entrepreneur Mishagin Vyacheslav Vladimirovich (INN 390609456123; OGRNIP 324390000046940). For email data submitted by a customer, the customer normally determines the purpose and lawful basis and Postline acts as processor under the applicable Terms, order, and DPA.
Purpose and roles
Postline processes service-account data to operate and secure the platform. For email data submitted by a customer, the customer normally determines the purpose and Postline acts as a processor under the applicable agreement.
Current retention
- Message records currently include recipient addresses, subject, and submitted text/HTML body and remain until project deletion, a verified deletion request, or an administrator cleanup. Plan retention labels are not yet an automated deletion guarantee.
- Login codes stop working after 10 minutes and dashboard sessions after 30 days; only hashes are stored by the API.
- The REST API rejects attachments. It accepts only In-Reply-To, References, List-Unsubscribe and List-Unsubscribe-Post custom headers (up to 8). Hosted mail is separate: the web client supports up to 20 attachments, 25 MiB total; the released desktop client has a 10 MiB sending limit. HTTP 202 and email.accepted mean acceptance into the processing pipeline; SMTP acceptance does not guarantee delivery or inbox placement.
- Suppression entries remain while their delivery-safety or legal basis remains valid.
Security and transfers
TLS protects supported network paths; it is not end-to-end email encryption. Mailbox passwords and TOTP secrets are encrypted by the application. Message bodies are stored for processing and history; this is not a claim that every stored record or backup is encrypted.
Requests
Customers can request access, correction, export, or deletion through privacy@srs-postline.com. Postline may require identity and authority verification and may retain data where legally or operationally required.
Browser storage
The marketing site does not store cookies or local-storage identifiers. After successful dashboard login, the dashboard sets the essential postline_session cookie described in the Cookie Policy.
