# Direct mail on autopilot for ProLine

> Point ProLine's webhooks at Mailr and it goes to work: projects, quotes, and invoices fire postcards into the right neighborhoods within seconds, landing-page leads land in ProLine through Web Leads, and approved quotes stop that home getting mail.

## How it connects

1. **Connect ProLine** — No API key needed. Paste Mailr's webhook URL into ProLine → Integrations → API → Webhooks, and your Web Leads URL into Mailr — the wizard shows you both.
2. **Pick trigger events** — Native events like Project created, Project reaches a stage, Project won, Project completed, Quote sent, Quote approved, Invoice sent, Invoice paid — filterable, e.g. “only won projects over $15k”.
3. **Approve and mail** — Approve the campaign once; cards print and mail automatically as events fire.

## Reactivation

Mailr keeps a running snapshot of every project and contact ProLine sends it, so Reactivation can import your past projects and contacts — by status, or since a date — and mail the nearest neighbors of every one.

## Lead delivery

Landing-page leads post straight into ProLine's Web Leads at capture time — name, phone, email, address, and message, auto-retried on failure — so they land in your pipeline like any other web lead.

## Automatic suppression

The moment a quote is approved in ProLine, that customer is removed from future mailing audiences. You never pay to advertise to someone you already closed.

## How fast triggers fire

Instant — ProLine webhooks (a two-minute setup Mailr walks you through) fire within seconds, and an hourly sweep backstops everything, deduped. Nothing missed, nothing doubled.

## Common questions

### What do I need to connect ProLine?

Nothing but your ProLine login. Webhooks and Web Leads are both configured inside ProLine — the Mailr wizard shows you exactly where — so there's no API key to find and no developer involved.

### Which events can fire mail?

Every project, quote, and invoice event ProLine sends: created, stage changed, won, completed, quote sent or approved, invoice sent or paid — each with custom-field filters on top.

### What does Mailr write back into ProLine?

Captured leads, through your ProLine Web Leads URL, so they arrive like any other web lead. Everything else is read-only: project, quote, and invoice events power triggers, Reactivation, and revenue attribution.

### How fast do triggers fire?

Instant — ProLine webhooks fire within seconds of the event. Every event is deduped, so a resend can never double-mail.
