# B2B Email Permutation Generator & Live SMTP Checker

**Use case:** 

Generate 14+ corporate email pattern permutations (first.last@, first@, flast@, firstl@, etc.) from First Name, Last Name, and Domain, then verify each inbox via live SMTP handshake in parallel. Never guess corporate email formats again ($5 per 1,000 verified emails found).

## 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/blessiticus/b2b-work-email-finder-5-1k-find-emails-linkedin-or-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`).
