# Direct mail on autopilot for Housecall Pro

## How it connects

1. **Connect Housecall Pro** — Paste an API key from Housecall Pro → My Apps → All Apps → API Key Management — validated live against your account before it saves, so a typo can't half-connect.
2. **Pick trigger events** — Native events like Job created, Job scheduled, Job started, Job completed, Job paid, Job canceled, Estimate created, Estimate sent, Estimate approved, Invoice created, Invoice paid, Customer created, Customer updated — filterable, e.g. “only completed jobs over $8k”.
3. **Approve and mail** — Approve the campaign once; cards print and mail automatically as events fire.

## Reactivation

Mailr imports your past jobs and customers from Housecall Pro — by work status, or since a date — then mails the nearest neighbors of every one. The customers source remails your whole book, not just addresses with a finished job.

## Lead delivery

Landing-page leads are created as Housecall Pro customers at capture time — “Mailr” as the lead source, deduped by email, anything that doesn't fit a field lands in the customer notes. Every lead deep-links straight to the customer in Housecall Pro.

## Automatic suppression

The moment an estimate is approved in Housecall Pro, that customer is removed from future mailing audiences. You never pay to advertise to someone you already closed.

## How fast triggers fire

Instant — signed Housecall Pro webhooks fire within seconds, and an hourly sweep backstops everything, deduped. Nothing missed, nothing doubled.

## Common questions

### What do I need to connect Housecall Pro?

An API key from Housecall Pro → My Apps → All Apps → API Key Management (admin access). Mailr checks it against your account before saving, then a 3-step confirm wizard shows real field samples from your own jobs.

### Do I have to set up webhooks myself?

Housecall Pro webhooks are signed, so the setup wizard shows you exactly where to paste Mailr's endpoint and signing secret. Skip it and everything still runs on the hourly sweep.

### What does Mailr write back into Housecall Pro?

Captured leads, as customers with the “Mailr” lead source. Everything else is read-only: jobs, estimates, and invoices power triggers, Reactivation, and revenue attribution.

### How fast do triggers fire?

Instant — signed Housecall Pro webhooks fire within seconds, and an hourly sweep backstops everything, deduped. Nothing missed, nothing doubled.
