Reloop

Reloop is an open-source email platform for transactional email, campaigns, inbound mail, templates, contacts and delivery analytics.

The stack includes PostgreSQL, Redis, NATS and persistent mail queues. Add DNS records for the main, link and inbound hostnames, then configure SPF, DKIM, DMARC and MX records in the dashboard before using email delivery. For sign-in codes and invitations, configure SMTP_HOST, SMTP_PORT, SMTP_USER, SMTP_PASSWORD and SMTP_SECURE, or set RELOOP_API_KEY and a verified RELOOP_SENDER_DOMAIN. Create the first administrator at /dashboard/setup using the generated ADMIN_SETUP_KEY from the deployment environment.
