SendGate — self-hosted open-source alternative to ZeroBounce / MillionVerifier
Lately I was spending most of my time working on an email validation package. But since i decided to focus Senlo more on transactional and product lifecycle emails, the need for this validation logic inside the main project kind of disappeared. so instead of letting that work just sit there, i decided to release it on github as a separate self-hosted service.
