What Reloop is

Reloop is an email delivery platform for transactional and programmatic workflows, available as a hosted service or for self-hosting. It provides a transactional API and SMTP relay, with webhook-based inbound routing and dedicated agent inboxes for programmatic email handling. First-party SDKs support Node.js, TypeScript, Python, Go, Rust, PHP, and Ruby; listed framework integrations include Next.js, Django, Ruby on Rails, and Laravel. Analytics cover delivery, opens, clicks, bounces, complaints, SMTP responses, and reputation. Template tools include AI-assisted generation, editing, previews, variables, and version history. Hosted plans provide 45 days of data retention, with plan-based limits on agent inboxes, webhooks, and custom domains. The Free plan allows 3,000 emails per month and 100 per day; sending pauses when either cap is reached. Pro costs $10 a month for 50,000 emails per month, with additional emails at $0.50 per 1,000. Self-hosting has no Reloop license cost, though server and delivery costs still apply. Reloop is open source under Apache 2.0 with Reloop Labs use restrictions.
