One platform, not three
Analytics, identity, segmentation, automation, and email on the same event stream and the same customer record. No reverse-ETL, no nightly syncs.
About
One pipeline from event to email.
GetFluxly is a customer data platform built for engineering teams who want lifecycle email driven by what users actually do, not by lists they keep in sync by hand.
Built for developers
A real SDK, a clean HTTP API, idempotency keys, batch endpoints, and a Console you can read like a debugger. Marketing tools live downstream of you, not above you.
Quiet, predictable, behavior-first
GetFluxly turns real product events into the messages your users actually need. No noisy growth gimmicks, no manual list maintenance, no surprises in the audit log.
Why we're building this
The lifecycle stack is held together with duct tape.
Most teams stitch together a product analytics tool, a CRM, an ESP, a reverse-ETL, and a Zapier flow. Each piece is fine on its own. The seams between them are where the actual lifecycle email work breaks down, and where the most valuable moments get lost. We're collapsing the seams.
01
Behavior is the source of truth.
Email tools send what you tell them to send. Behavior happens in your product. We treat the event stream as canonical, with segments, profiles, and automations all just views over it.
02
Developers decide what gets tracked.
If your engineers don't trust the data, your marketing won't either. The SDK and API are first-class. The Console is for inspecting and operating; the source of truth lives in your code.
03
Boring infrastructure beats clever infrastructure.
We don't rebuild your data warehouse, and we don't pretend an event pipeline is a thinking machine. We do one thing: turn product events into well-timed emails, and we get out of the way.
04
Quietly confident, never loud.
No "delightful." No "powerful." No exclamation points. The product earns trust by being precise, fast, and predictable. The marketing should look the same.
05
Self-hostable on day one.
The control plane runs on Postgres and a couple of Go workers. The dashboard is a static React build. If you ever want to take the whole thing in-house, you can. Most won't, but the option matters.
