Deliverability & the inbox8 min

Apple Mail Privacy Protection, four years in

Apple broke the open rate in 2021. Half the lifecycle industry is still pretending it didn't happen. Four years on, the programs that actually adapted are beating the ones that kept optimising a metric that doesn't exist anymore.

Channel & craft9 min

Braze naming conventions that survive a Friday afternoon

Every Braze workspace eventually becomes an archaeological dig. The convention that actually holds is four dimensions, six seconds to apply, and enforced by tooling rather than a Notion page nobody reads.

Strategy & economics10 min

Retention economics: proving lifecycle ROI to finance

Lifecycle programs get deprioritised when they can't defend their impact in dollars. The four models that keep the budget — LTV, payback, cohort retention, incrementality — and the four-slide pattern that wins a CFO room.

Programs & flows9 min

The welcome email sequence: the 7-day shape that actually moves new signups

Most welcome sequences over-pitch, under-onboard, and keep firing long after the user has either started using the product or wandered off. Here's the 7-day shape that gets new signups to a real first action — shorter, sharper, conditional on what they actually did — plus the stop rules that keep it from training people to ignore your email.

Measurement & testing10 min

A/B testing in email: sample size, novelty, and what to report

Most email A/B tests produce winners that don't reproduce. Three reasons keep showing up: under-powered samples, the novelty effect, and weak readout discipline. This guide is about designing tests that actually drive decisions instead of theatre.

Why Gmail clips emails at 102KB (and how to stop it)

Gmail has been clipping emails over 102KB since 2013. The 'View entire message' link almost nobody clicks is where your unsubscribe, secondary CTA, and legal footer go to die. Here's how bytes actually pile up and the discipline that keeps every send under the threshold.

Why Orbit exists

Built from 10+ years of doing this work.

Orbit isn't built by a team guessing what lifecycle marketers need. It's built by one person, from a decade of CRM and lifecycle work across consumer-scale programs — mostly on Braze.

Every skill comes from a real problem. The discovery questions I wish I'd asked earlier. The naming conventions that saved hours of cleanup. The QA steps that caught broken Liquid before it reached millions of inboxes.

I built Orbit to help me scale faster. It turned out to be useful for the whole lifecycle community, so it stays free — every guide, course, and tool, and the MCP that does the work for you.

The flagship path

Build your own lifecycle brain.

Orbit's flagship path isn't writing one email. It's giving the programme somewhere to live. Most lifecycle work rots for two reasons: the knowledge lives in one person's head, and the templates drift inside the ESP — the platform that actually sends. The repo is the source. The ESP is a derived output.

This is a design system derived from the email you already send, not a vendor's template gallery.

orbit_bootstrap_brain

Scaffold the repo

A git repo with operating rules, conventions, a folder per lifecycle stage, and the standing knowledge logs — the single source of truth for your programme.

orbit_learn_email_template

Ingest what you already send

Point it at an email you have shipped — HTML, Figma or PDF — and it derives a module catalogue plus brand tokens. That is your design system, taken from your real email.

orbit_generate_brain_gate

Generate the pre-send gate

A gate parameterised to your byte limits and templating branches. This is the difference between a design system and a folder of files.

orbit_scaffold_brain_program

Frame each programme

One PRD stub per programme — the one-page spec — so AI drafts never get built unreviewed.

Ask Claude: “Scaffold me a lifecycle brain from the last email I sent.” More starter prompts →

Capabilities

Figma Import

Import email designs from Figma and convert them to production code automatically.

Works with your stack

Works with the ESP you already run.

Orbit is methodology first, integration second. The skills, the frameworks, and the production email work — MJML and HTML built to render everywhere — run the same whether you send on Klaviyo, Iterable, HubSpot, Customer.io, Mailchimp, Salesforce Marketing Cloud, or Braze. No migration. No lock-in. Bring your stack.

Deepest integration: Braze.

Connect your API key and Claude reads every Canvas, campaign, and segment, then writes templates and Content Blocks straight back. The rest of the ESPs are catching up.

Instance Audit

Inventory your entire Braze workspace. Surface naming issues, stale content, and duplicates.

Canvas Reader

Read any Canvas and import its structure as an editable program.

Performance Data

Pull Canvas, campaign, and segment performance data over any time range.

Data Validation

Check that the events and attributes in your plan actually exist in Braze.

Template Sync

Publish templates and Content Blocks to Braze with version tracking.

Segment Analysis

Analyze segment sizes, growth trends, and tracking configuration.

Stripo email builder

Build in Stripo, push to Braze.

The Stripo-to-Braze push is Braze-only today — one command, no clipboard. On every other ESP you copy the finished HTML into your builder. More native pushes are on the roadmap.

Compose in chat

Brief Claude in plain language. It stitches your saved Stripo modules in the right order and renders the actual email inline.

Export to Braze

Send the finished email to a Braze template, deduped by name — no duplicate "Welcome Email (2)" to untangle later.
