Good fit for Engineers who want a programmable SMTP layer and are comfortable shipping a small amount of glue code.
Weak at No GUI, no batteries-included dashboard; deliverability tooling is what you build.

Replaces these SaaS
- SendGrid · Transactional email API
Haraka is a Node SMTP framework, not a finished product. You install it, enable plugins (`tls`, `dkim_sign`, `outbound`), point your app at it via SMTP, and get a programmable, scriptable relay. Migration from SendGrid means dropping the HTTPS API in favor of SMTP and building any UI/dashboard you need.
