Subprocessors
Systems that may process customer personal data in providing Reloop Cloud.
Reloop Cloud runs on infrastructure and systems operated by Reloop Labs itself. As of the date above, no third-party vendor has standing access to Customer Personal Data as defined in our Data Processing Addendum. The table below lists the systems involved in providing the hosted service.
1. Systems
| System | Purpose | Data involved |
|---|---|---|
| PostgreSQL | Primary application database for accounts, domains, contacts, campaigns, and delivery records. | Account data, contact and recipient data, message metadata. |
| Redis | Sessions, rate limiting, caching, and short-lived pipeline state. | Session identifiers, rate-limit counters, transient job state. |
| NATS JetStream | Internal message queue carrying mail-pipeline events between service components. | Message metadata and delivery events in transit. |
| MinIO | Object storage for attachments, templates, and exports. | Message content including attachments, templates, export files. |
| ClickHouse | Analytics store for delivery and engagement events. | Delivery events (sends, bounces, complaints, opens, clicks). |
| KumoMTA | Outbound and inbound SMTP delivery agents. | Message content and envelope data during transmission. |
| Rspamd | Spam, phishing, and abuse scanning of inbound mail. | Inbound message content during scanning. |
| Inngest | Orchestration of background workflows such as automations and drips. | Workflow state referencing contact and message metadata. |
| Lago | Usage metering for billing. | Aggregated sending volumes per account. |
| Caddy | TLS-terminating edge proxy in front of the service. | No persistent storage; connection metadata in transit only. |
