## Pipeline Workflows

### Tab 1 — AirScale → Email
1. Export companies from AirScale as CSV
2. Upload → map domain column
3. Select decision maker categories
4. Start Enrichment → bulk API runs asynchronously
5. Export CSV/Excel

### Tab 2 — LinkedIn Sales Navigator → Email
1. Build search in Sales Navigator, copy URL
2. Paste URL + set max results → Start Scrape
3. Vayne scrapes profiles (polls until done)
4. Select profiles → Enrich with Emails
5. Export results

### Tab 3 — SERP → Email
1. Enter search term (e.g. `"Solaranlage Installateur Deutschland"`)
2. Set country/language, enable social filter
3. Select decision maker categories
4. Start → Apify scrapes Google, domains extracted, then bulk enriched
5. Export results

## How Anymailfinder Bulk Works

1. All domains submitted as one POST to `/v5.1/bulk/json`
2. Poll status every 5s until `completed`
3. Download results once (credits charged at download, not submission)
4. Speed: ~1,000 domains per 5 minutes

## Database

SQLite at `./leadflow.db`. Inspect with:

```bash
npx prisma studio
```

## Troubleshooting

| Issue | Solution |
|-------|----------|
| "API key not configured" | Add key in Settings |
| Job stuck at "running" | Check server console (`npm run dev` terminal) |
| Prisma errors on build | Run `npx prisma generate && npm run build` |
