Hey HN, we are sharing again, after a year of updates! Laudspeaker (https://laudspeaker.com/) is an open source customer engagement suite (also called marketing automation software). If you've used tools like Braze, One Signal, Airship, Iterable, Customer.io or some others, Laudspeaker is an alternative to these. Here is a quick demo: https://www.loom.com/share/4b309390ee274ea491981e1394e9abc4. And here is a link to sign up and try free (no cc needed): https://app.laudspeaker.com/signup. Or if you prefer to just jump in, go to https://app.laudspeaker.com/login and use this test account: email: [email protected] pw: [email protected] The main things Laudspeaker lets you do are: 1. Define 'segments': which of your users should receive messages. 2. Define 'messaging journeys': when, where and with which channels you want to reach users. Right now we support push, email, SMS, and soon we'll also include in-app messages and WhatsApp. For example, one customer of ours runs a journey like this: "Wait for a user to complete onboarding on our mobile app, then send a welcome push. If they complete an action the next day on the app, stop sending messages, otherwise send a followup email." There are quite a few big updates since our last Show HN (https://news.ycombinator.com/item?id=34835559): We now have a mobile SDK for sending and receiving push notifications. We have revamped the journey builder, and made our segment builder much more comprehensive. Our application is also a lot more battle tested - we are deployed with a major fintech in Asia and are sending XX million messages a week to more than x million users. We've seen a lot of demand from consumer focused apps and websites who find most of the existing solutions' pricing models prohibitively expensive so please reach out if that sounds like you. We have successfully migrated people over from Braze, customer io and others.
