Ask HN: What is a good open-source marketing automation tool
I'm looking for an open source marketing automation tool, i.e. something that allows you to create segments of your users and send triggered transactional emails (like braze, salesforce marketing cloud, intercom, etc). Any recommendations, folks? Not really open source but a small one time fee.
https://sendy.co/ This looks very useful for newsletters, but what I'm seeking is a tool that lets you create a live segment of users and send a message to them when they enter the segment. So - transactional product emails, rather than newsletters.
