Reloop
Reloop is an email delivery platform for transactional and programmatic workflows, available as hosted plans or self-hosted on infrastructure you control. It provides a transactional API and SMTP relay, plus webhook-based inbound routing and dedicated agent inboxes. 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. Templates support AI-assisted generation, editing, previews, variables, and version history. Hosted plans retain data for 45 days and set limits for 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 overage at $0.50 per 1,000 emails. 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.
