Open source alternatives to Loops[007]

Loops sends marketing and transactional email for software companies, with event-triggered sequences, segments and analytics. Below are 7 self-hostable open source alternatives, ranked by GitHub popularity.

// EDITOR'S TAKE

Plunk is the closest fit, because like Loops it treats transactional and marketing email as one system driven by product events rather than two separate tools. Listmonk is far more mature and handles very large lists efficiently but is campaign-oriented with no real event triggers, and useSend is the leaner developer option when you mostly want an API over your own sending setup.
