Cllavio – Email Marketing and Email API platform built from scratch

Hacker News

Hi HN, I'm the solo founder of Cllavio, an email marketing + email API platform that I built from scratch. My goal was to create a simpler, faster, and more transparent alternative to typical email tools that hide essential features behind expensive tiers. Cllavio includes: - Email campaigns - SMTP + REST email API - Deliverability tools (SPF, DKIM, DMARC) - Bounce tracking - Analytics (opens, clicks) - Contact management - High-deliverability Postfix infrastructure on AWS If you’re into email infrastructure, Spring Boot, Postfix, or scalable messaging systems, I’d love your feedback or questions.
