Reviewer scorecard
“Heroku DX on your own infrastructure. Docker-based deploys, SSL, and monitoring without cloud vendor lock-in.”
“The API is clean, the React Email integration is brilliant, and deliverability is excellent. Replaced SendGrid in 20 minutes and never looked back.”
“If you want control over your infrastructure without raw Docker/K8s complexity, Coolify is the sweet spot.”
“Young company with a smaller scale than SendGrid or Postmark. But the developer experience is so much better that it's worth the risk for startups. Monitor deliverability closely.”
“The self-hosting movement is growing. Coolify makes it accessible to developers who don't want to be sysadmins.”
“Building beautiful transactional emails used to be painful. React Email components make it feel like building a web page. Game changer for my client projects.”
