Transactional Messaging for SaaS teams - One API for all your product notifications

by•
Staccats is a transactional messaging platform for SaaS. Define events like invoice_overdue or password_reset and send email, or in-app notifications through one event-based API. Multi-tenant support, provider-agnostic routing (SendGrid, SES, etc.), and searchable logs make it easy to debug issues and embed notification history in your own app.

Hey PH 👋 I’m one of the makers of Staccats. We built it after repeatedly re-implementing notification systems inside SaaS products, wiring SendGrid directly into app code, hacking together logs, and regretting it when we had to change providers or add channels. With Staccats, the idea is simple: - Treat notifications as events, not ad-hoc function calls - Use a single headless API for email / webhooks - Keep everything multi-tenant aware from day one - Expose logs & history back inside your own product A typical integration looks like this: await staccats.notify({ event: 'invoice_overdue', userId: 'user_123', data: { amount: '$120', dueDate: '2025-01-15' } }) Behind the scenes, Staccats picks the right template and provider, sends the notification, and records attempts so you can debug issues or show history to support teams and customers. I’d love feedback on: - What would make you comfortable using this in production? - Which channels/providers you’d want first? - Any “I wish my notification system could…” wishes from your current stack. Happy to answer any technical questions about how it’s built or where it’s going!

This is really amazing. So do you handle all kinds of notifications (both in-app and emails)?
What about the content?

@chilarai Currently just in-app and emails. The content is controlled by the templates you create, and can be chosen for each notification/message sent.

@stacware_team Amazing. I would love to explore more about this product. How about a demo sometime?

I think it's really wonderful how you took insights from a personal problem and turned it into a legible product. Really glad to have you part of the @Flowglad community and excited to see what else you come up with in the future!
