# Enrich a conference attendee list

Event lists usually arrive as a name and a company name, sometimes a title, rarely an email. This skill resolves each company to a domain, finds each person's work email, verifies it and fills in missing titles, so the user can follow up after the event.

## When to use

- After a conference, trade show or meetup when the user has a badge-scan export or a published attendee list.
- Rows have `Name` and `Company` but no email or website.
- For lists that already have domains, enrich-csv with `search_business_email_by_name` is simpler.

## Before you start

1. Check the connection: `npx ravn whoami` (free).
2. `search_business_profile_by_name` and `search_companies` need your own provider key connected — run `ravn keys add pdl` first; these tools run on your own provider account. If a tool returns 403 `provider_key_required`, stop and tell the human to add their key. Finding and verifying emails are ours and need no key. Every call is one lookup; misses are free.
3. Ask where the list came from. Badge scans of people who visited the user's booth are a warm audience. A list of all attendees bought or scraped from elsewhere may not be allowed under the event's terms; check before going further.

## Steps

1. Resolve company names to domains. The email finder needs a domain. For each unique company name:
   - If you know the domain with confidence, use it.
   - If not, call `search_companies` with the name as `query` and `limit` 1 (one lookup per company found). Confirm the match by name and country.

```json
{ "query": "Northwind Logistics", "limit": 1 }
```

   - If still unsure, leave the domain blank and mark the row `needs_domain`. Do not guess.
2. Write the domain into a new `Domain` column and save `attendees-domains.csv`.
3. Find emails. Dry run, sample, full:

```bash
npx ravn enrich attendees-domains.csv --tool search_business_email_by_name --map name=Name,company=Domain --dry-run
npx ravn enrich attendees-domains.csv --tool search_business_email_by_name --map name=Name,company=Domain --limit 10 --out sample.csv
npx ravn enrich attendees-domains.csv --tool search_business_email_by_name --map name=Name,company=Domain --out attendees-emails.csv
```

Each hit already carries a verdict in `rw_verdict`, plus `rw_pattern` and `rw_confidence`.
4. Fill titles where the list has none, only if the user wants them. Make a copy of the rows with an empty title, rename the step 3 `rw_*` columns (for example `rw_email` to `found_email`, `rw_verdict` to `email_verdict`) so the next pass does not clash, then:

```bash
npx ravn enrich no-title.csv --tool search_business_profile_by_name --map name=Name,company=Domain --dry-run
```

5. Sort by verdict: keep `valid`; mark `risky` (catch-all) and `unknown` for manual review; drop `invalid`.
6. Tag each row with the follow-up track the user wants, for example `visited_booth`, `attended_talk`, `general`.

## Output

`attendees-enriched.csv` with the original columns plus:

- `Domain` and `domain_source` (`known`, `search_companies` or blank)
- `rw_status` (`ok`, `not_found`, `error`, `dropped`), `rw_email`, `rw_verdict`, `rw_risk_score`, `rw_pattern`, `rw_confidence`
- Title fields from the profile pass, where run
- `follow_up_track`

Summary: attendees in, domains resolved, emails found, valid versus risky, titles filled, and lookups used.

## Rules

- Respect the event's terms for how the list can be used, and honour any "do not contact" flag on the export.
- Never contact anyone who opted out. See [/privacy#optout](https://askravn.com/privacy#optout).
- Drop invalid and risky emails before any automated send.
- No FCRA uses.
- On a 429 `fair_use_exhausted` or a 403 `provider_key_required`, stop and tell the human; rows not reached are `dropped`.

## Example prompt

> We scanned 220 badges at the logistics expo. The export just has Name, Company and sometimes Title. Get me verified work emails and titles so we can send follow-ups on Monday.
