# Email Validation - Bulk Email Verification (`pink_comic/email-validation-checker`) Actor Validate email addresses with format checks, MX record verification, and deliverability scoring. Detect disposable emails and catch-all domains. For list cleaning, lead verification, and reducing bounce rates.

The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Email Validation & Verification ($0.50/1K) Validate email addresses in bulk with no API key required. Clean your email lists before campaigns, verify leads, and reduce bounce rates. ### What it does For each email address, the actor checks: - **Syntax validation** - RFC-compliant email format check - **MX record lookup** - Verifies the domain can receive email - **Disposable domain detection** - Flags temporary/throwaway email services (Mailinator, Guerrilla Mail, etc.) - **Free provider detection** - Identifies Gmail, Yahoo, Outlook, etc. - **Role account detection** - Flags generic addresses (info@, admin@, support@, etc.) - **Catch-all detection** - Identifies domains that accept any address - **Domain typo suggestions** - Suggests corrections (gmial.com -> gmail.com) - **Optional SMTP verification** - Connects to the mail server to check if the mailbox exists ### Use cases - **CRM cleanup** - Remove invalid emails from your contact database - **Lead verification** - Validate scraped email lists before outreach - **Email campaign prep** - Reduce bounce rates and protect sender reputation - **Data quality** - Flag disposable, role-based, and catch-all addresses - **List hygiene** - Identify free vs business email addresses ### Input | Field | Type | Description | |-------|------|-------------| | emails | string[] | Email addresses to validate | | enableSMTP | boolean | Enable SMTP reachability check (default: false) | | maxResults | integer | Maximum emails to validate (default: 100) | | concurrency | integer | Parallel validations (default: 5, max: 20) | ### Output Each email produces a result with: ```json { "email": "user@gmail.com", "valid": true, "syntaxValid": true, "mxFound": true, "disposable": false, "freeProvider": true, "roleAccount": false, "catchAll": false, "domain": "gmail.com", "localPart": "user", "mxRecords": "gmail-smtp-in.l.google.com, alt1.gmail-smtp-in.l.google.com" } ```` ### Use with AI Assistants (MCP) This actor works as an MCP tool with Claude Desktop, Cursor, and other MCP clients. **Setup:** Add this to your MCP client configuration: ```json { "mcpServers": { "email-validator": { "url": "https://mcp.apify.com?tools=pink_comic/email-validation-checker" } } } ``` Then ask your AI: *"Validate these email addresses: john@example.com, sales@acme.com"* -- it will run the validator and return results. ### Pricing $0.50 per 1,000 emails validated. No API key or external account needed. ### Notes on SMTP verification SMTP checking connects directly to mail servers to verify mailbox existence. This is disabled by default because: - Datacenter IPs are frequently blocked by major mail providers - Some servers use greylisting which causes false negatives - Catch-all domains always report "deliverable" For most use cases, syntax + MX + disposable detection provides sufficient accuracy (~85-90%) without SMTP. # Actor input Schema ## `emails` (type: `array`): List of email addresses to validate. Checks syntax, MX records, disposable domains, free providers, and role accounts. ## `enableSMTP` (type: `boolean`): Enable SMTP reachability check (connects to mail server to verify mailbox exists). May be unreliable from datacenter IPs. Disabled by default. ## `maxResults` (type: `integer`): Maximum number of emails to validate. ## `concurrency` (type: `integer`): Number of emails to validate in parallel. Higher values = faster but more DNS/network load. ## Actor input object example ```json { "emails": [ "test@gmail.com", "user@mailinator.com", "ceo@apple.com", "info@microsoft.com", "fake@nonexistent-domain-12345.com" ], "enableSMTP": false, "maxResults": 100, "concurrency": 5 } ``` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "emails": [ "test@gmail.com", "user@mailinator.com", "ceo@apple.com", "info@microsoft.com", "fake@nonexistent-domain-12345.com" ] }; // Run the Actor and wait for it to finish const run = await client.actor("pink_comic/email-validation-checker").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
