## FAQ

### What does the company email format task return?

The company email format task returns one row per domain with the pattern, a readable format, an example, how many people confirm it, how much they agree, and any other patterns seen.

### What input does the company email format task need?

Provide company domains, website URLs or emails, which are reduced to the domain. Optionally raise sampleSize to read more of a large company's people for a steadier pattern.

### How do I run company email format lookup from the API, on a schedule or into a spreadsheet?

Run this company email format lookup task from the Apify console, call it through the API with your own input, or put it on a schedule. Export the dataset as CSV or JSON to open it in Google Sheets or Excel.

### What if a company has too little evidence for an email format?

When the company email format task finds thin evidence for a domain, it returns a notice row instead of a guessed pattern, so you only act on formats backed by real addresses.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/b2bdata/email-pattern-by-domain.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
