mxRaven is a programmable email delivery platform for not any one particular thing, but rather a flexible glue which can be used to build anything that requires receiving or sending emails in some form, be it agent mailboxes, personal mailboxes, transactional email, marketing campaigns etc. Think of it as a sort of WAF + Application Layer Router but for the SMTP world with ergonomic SDKs for keeping the developers in the driver's seat.

For this public demo (https://sandbox.mxraven.com/), I vibecoded a sandbox that (tries) to preview as many mxRaven features as possible publicly without possibility of abuse. You can try to send or receive emails from and to your designated sandbox addresses and play with some basic subset of programmable rules (https://mxraven.com/docs/concepts/routing-and-actions/introd...)

You can read the details about mxRaven from the docs https://mxraven.com/docs/concepts/start-here/why-mxraven/ and check out our first-party SDKs we have so far:

P.S. Unlike some of our competition we do not use relays like AWS SES. In fact mxRaven was born from the open source raven library (https://github.com/synqronlabs/raven) a high performance comprehensive ESMTP toolkit I wrote in Go. We ARE the email relay, and even the core transport and email auth library is first party and open source, something I am very proud of.
