# Check a cold outreach email list before you send

The Email Verifier with Owner Profile Actor is ready to run with the inputs already set for "Check a cold outreach email list before you send". [Sign up or log in](https://console.apify.com/create-task-from-example/OY6OsKzLO6omDblVv) and you'll land in Apify Console with a copy of this exact task.

### 2. Start the "Check a cold outreach email list before you send" task

The Email Verifier with Owner Profile Actor will start running based on the input automatically. You can also change all the input fields, like which email addresses?, max results in total, and more, to match your specific use case.

### 3. Receive the "Check a cold outreach email list before you send" output

Monitor the progress in real time. You will be notified as soon as your dataset is complete and ready for review. Each result includes data such as email, status, domain, and more.

### 4. Integrate into your workflow

The final output is delivered in JSON, CSV, or Excel format, ready to be plugged into your workflow. You can also [run the "Check a cold outreach email list before you send" task via API](https://apify.com/b2bdata/email-verifier.md).

## FAQ

### What does the outreach list email checker return?

The outreach list email checker returns one row per address with an email status of valid, invalid or catch-all, the domain, mail server, and owner name, title and company when known.

### What input does the outreach list email checker need?

Provide email addresses in the items field, one per entry. A Name <address> form is reduced to the address, repeats are checked once, and non-addresses are listed in the misses record.

### How do I run outreach list email check from the API, on a schedule or into a spreadsheet?

Run this outreach list email check 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.

### How should I read unknown results from the outreach list checker?

Large mail providers do not reveal whether a mailbox exists, so the outreach list checker reports those as unknown. Treat unknown as undecided, not as a rejection.

## About this Actor

This example demonstrates how to use [Email Verifier with Owner Profile](https://apify.com/b2bdata/email-verifier.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/b2bdata/email-verifier.md) to learn more, explore other use cases, and run it yourself.


## 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-verifier.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`).
