Our verdict on Reloop
Reloop is an open-source email infrastructure platform for developers, DevOps teams, and marketing teams. It supports transactional delivery through a REST API and SMTP relay, alongside inbound email processing, templates, delivery analytics, event webhooks, contacts, suppression management, campaigns, and workflows. Teams can use it as a hosted service or deploy it themselves with Docker, Kubernetes, or bare metal infrastructure.
The hosted plans provide a clear progression. Free costs $0 per month and includes community support, with 50,000 monthly emails. Pro costs $10 per month and adds dedicated support and no daily limit. Growth costs $20 per month and includes one dedicated IP, dedicated support, and no daily limit. Enterprise includes dedicated support and an SLA. Self-hosting has no Reloop license fee, while infrastructure and email delivery costs still apply. This structure suits teams that want to start without a license charge and move to paid support or dedicated delivery resources as requirements grow.
Reloop also fits development stacks that value deployment flexibility. Its integration list includes Vercel, Railway, Cloudflare, Netlify, Docker, Coolify, Lovable, Bolt.new, v0, Replit, MCP Server, Cursor, Windsurf, n8n, and Make.com. Official SDKs for multiple programming languages support application integration, while real-time delivery logs and analytics, templates, contacts, lists, suppression management, and workflows cover operational needs around email programs. Choose Reloop if open-source access, self-hosting, API and SMTP delivery, and broad ecosystem compatibility matter. Teams wanting a narrowly focused transactional email service may not need its wider campaign and workflow scope.
