GetFluxly is a product analytics + lifecycle email platform. It captures browser and server events through a JavaScript SDK or HTTP Events API, builds unified customer profiles, and triggers lifecycle email through the email service provider your team already uses.

How do I install the GetFluxly browser SDK?

Install the @getfluxly/sdk-js package from npm or drop the script tag onto any page. Set window.__GFLUX__ with your API key, then GetFluxly auto-captures pageviews, clicks, and form submissions out of the box. The window.gflux global exposes identify, track, reset, and destroy.

What does GetFluxly do?

GetFluxly captures product events from your app through a JavaScript SDK or HTTP Events API, builds unified customer profiles, and runs behavior-driven lifecycle automations on top of those profiles.

When does the private beta open?

The free private beta opens May 18, 2026. Accepted teams get three months of full GetFluxly platform access at no cost. Request access from /request-access.

Is GetFluxly developer-friendly?

Yes. The browser SDK is 7KB minified, ships zero-config auto-capture, and the HTTP Events API accepts JSON over POST with a Bearer gf_live_… token. SDK examples are available for React, Next.js, Vue, Svelte, Node.js, Express, Python, Go, PHP, and cURL.

Email editor

Compose lifecycle emails. Personalize from the same profile that triggers them.

A block-based editor wired directly to your event stream. Drop in personalization tokens, branch on plan or behavior, preview against real profiles, and send a test before you commit.

From hello@getfluxly.comTo {{user.email}}Subject {{user.first_name}} — your first project is one click away

Hey Neo, your first project is waiting.

You signed up {{user.signup_age_days}} days ago but haven't created a project yet. The fastest way to feel what your team can do here is to start one — even an empty one. We'll have it ready in under a minute.

If this isn't useful, you can unsubscribe from onboarding emails. We won't send these forever.

Add block

Block-based, not blank-canvas

Heading, text, button, image, columns, divider, condition, raw HTML. Drag in, drop out. No template chaos.

Variables from real profiles

Any trait, any event property, any computed value on the profile. Type two braces to insert.

Conditional blocksComing soon

Show a block only if the user is on a specific plan, in a segment, or matches a property. One template, many audiences.

Test against a real profile

Render the email exactly as it'll send for any profile in your workspace. Catch broken variables before they go out.

Built for lifecycle, not for newsletters

Behavior in. Personalized email out.

The editor isn't a separate tool — it lives next to the same automations and segments that decide who gets the email. Edit the template and the next run picks it up.

Variables

Any trait. Any event property. Any computed field.

Use anything that's on the profile — no separate "merge fields" to maintain. When a trait updates, the next send picks it up.

Conditional blocksComing soon

One template, many audiences.

Show or hide a block based on plan, segment, or any trait. The same trial-activation email can read differently for free, team, and self-serve users.

Test mode

Preview the email as any real profile.

Pick a specific profile, render the template the way it'll actually send for that user, and ship a test send to your inbox before going live.

Specs

The boring details (that aren't, actually).

Rendering

Rendered server-side, sent through your provider

Templates render to HTML on send, with your variables resolved against the customer profile at that exact moment. Not at template-edit time, not at queue time.

Compatibility

Email client compatibility you can audit

HTML output uses table-based layouts under the hood. Renders cleanly in Gmail, Apple Mail, Outlook 2016+, and the major mobile clients. Dark-mode friendly.

Versioning

Every save is a version

Every save creates a version you can roll back to. See who changed what, when, and which automation runs used which version of the template.

Localization

Locale-aware (coming soon)

Per-locale variants of the same template, picked by user.locale. Shipping during beta.

Try it during the private beta

Compose your first lifecycle email in under 10 minutes.

During beta, the email editor is included with full access — no separate plan, no add-on. Pair it with a single tracked event and a one-step automation, and you've got behavior-driven email running.
