# Lifecycle Mail Cadence

> Fire a milestone email cadence with an approval gate, idempotency, and no speculative figures.

A milestone email dispatcher that fires a fixed cadence (day 0, 3, 7, 14, 21, 30, 60, 90) from a scheduled-email queue and sends through a transactional email API. An approval gate hard-blocks any client email from going out before a new template is reviewed, an idempotency key makes a double send mathematically impossible, and a no-speculative-figures rule keeps invented numbers out of the body. Bounce and complaint webhooks automatically pause sending and raise an alert, so the list stays clean.

## Use cases
- Sending a consistent milestone email cadence to every client automatically
- Reviewing a new email template safely before it can reach a client
- Preventing duplicate sends with an idempotency key
- Auto-pausing a contact after a bounce or complaint
- Keeping speculative or invented figures out of client emails
- Tying email sends to lifecycle stage transitions

## Benefits
- Every client gets the same cadence with zero operator drift
- No client email ships before it passes an approval gate
- Duplicate sends are impossible thanks to idempotency
- List health protected by automatic bounce and complaint handling

## What’s included
- A fixed milestone cadence from day 0 through day 90, driven from a scheduled queue
- An approval gate that hard-blocks unreviewed client emails
- An idempotency key that makes double dispatch impossible
- A no-speculative-figures rule for email bodies
- Bounce and complaint webhook handling that pauses sending and alerts
- Stage-transition triggers that queue the right milestone email

## Who it’s for
Teams running lifecycle email at scale who need consistent timing, a safe review gate, and zero duplicate or speculative sends.

## How it runs
Lifecycle email fails on drift, duplicates and unreviewed sends. This dispatcher closes all three with a queue, a gate and an idempotency key:
1. Reads the due milestones from a scheduled-email queue on a daily run and matches each contact to the right cadence day
2. Routes any new template through an approval gate first, hard-blocking a live send until it is reviewed and signed off
3. Checks the idempotency key before dispatch so the same contact, milestone and date can never send twice
4. Sends through a transactional email API and scrubs the body of speculative or invented figures
5. Listens to delivery webhooks and, on a bounce or complaint, pauses live sending for that contact and raises an alert

## FAQ
### How does it stop a client getting the same email twice?
Every send carries an idempotency key tied to the contact, milestone and date. If that key already exists, the dispatch is skipped, so a duplicate is mathematically impossible even if the job runs twice.

### What is the approval gate for?
A new template is first routed to an internal address with a clear prefix, so it is reviewed before any real client receives it. Only after sign-off does live sending switch on for that template.

### What happens on a bounce or spam complaint?
The bounce and complaint webhooks automatically turn off live sending for that contact and raise an alert, so a bad address or an unhappy recipient cannot keep getting mail.
