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 Verifier & Validator - Bulk Email Verification ✉️✅ The **fastest, cleanest, and most transparent** native email verification engine on Apify. Stop relying on expensive third-party APIs or basic format checkers. This actor combines advanced syntax parsing, deep DNS/MX checks, live SMTP mailbox probing, and **Gravatar "Proof of Life"** integration to verify bulk emails with zero API fees. ### Why Use This Verifier? 🚀 Most free email verifiers suffer from the "Accept-All" problem (they can't tell if a Gmail address actually exists, so they just guess or fail). We solved this using a **two-tier fallback system**: 1. **Live SMTP Probing:** We establish a real handshake with the mail server (port 25) to check if the exact mailbox exists. 2. **Gravatar Proof of Life:** For massive "Accept-All" providers like Gmail or Yahoo, standard SMTP fails. We instantly hash the email and query the global Gravatar registry. If a profile photo exists anywhere on the web, we upgrade it to **100% Valid**. Plus, we load a **live blocklist of over 7,500+ disposable domains** on every run so you never waste time emailing burners! --- > 💡 **Pro Tip: Support the Project!** > If this bot saves you hours of manual validation and protects your sender reputation, please drop us a **5-star review**! ⭐⭐⭐⭐⭐ It helps us keep the tool updated and free for basic usage! --- ### What It Checks 🔍 * **Syntax Validation:** Catches bad formats and enforces provider-specific rules (like Google's period rules). * **DNS & MX Records:** Validates that the domain can actually receive mail. * **Disposable Domain Detection:** Uses a dynamically updated list of 7,500+ burner domains. * **Role-Based Filters:** Flags generic corporate emails (`info@`, `admin@`, `support@`). * **Live SMTP Handshake:** Connects directly to the mail server to verify the exact user without sending an email. * **Gravatar Fallback:** Bypasses Gmail/Yahoo limitations by checking for an active web profile. ### Output Schema 📊 To make things incredibly simple for you, the output includes a dedicated **`isRealEmail`** column. | Column | Type | Description | | :--- | :--- | :--- | | `isRealEmail` | `Boolean / String` | The ultimate verdict. Returns `True` (it's safe), `False` (it will bounce), or `"Unknown"` (could not be 100% confirmed). | | `status` | `String` | Technical status: `valid`, `invalid`, `risky`, or `unknown`. | | `reason` | `String` | Exact reason (e.g. `mailbox_exists`, `bad_syntax`, `gravatar_confirmed`). | | `email` | `String` | The email address checked. | | `domain` | `String` | The extracted domain. | ### Free Tier Limits 🛑 To protect our servers from abuse, runs on the **Free Tier** are strictly capped at **10 emails per run**. If you need to process large CSVs or lists of thousands of leads, please rent the actor or upgrade your Apify plan to unlock unlimited verification concurrency! # Actor input Schema ## `emails` (type: `array`): List of email addresses to check. ## `smtpProbe` (type: `boolean`): Connect to the mail server to check if the mailbox actually exists. Needs outbound port 25. ## `timeoutSecs` (type: `integer`): How long to wait per mail server before giving up. ## `fromAddress` (type: `string`): Sender address used in the SMTP probe (not emailed). ## `concurrency` (type: `integer`): How many emails to verify in parallel. ## `useGravatar` (type: `boolean`): If an email is 'unknown' (like Gmail), use Gravatar to check if an avatar is registered. A hit upgrades it to 'valid'. ## Actor input object example ```json { "emails": [ "info@apify.com", "support@github.com", "asdkjhaskjdh99q@gmail.com", "x@mailinator.com", "test@thisdomaindoesnotexistxyz123.com", "bademail" ], "smtpProbe": true, "timeoutSecs": 10, "fromAddress": "verify@email-check.io", "concurrency": 8, "useGravatar": true } ```` # Actor output Schema ## `email` (type: `string`): The email address tested ## `isRealEmail` (type: `string`): Boolean or Unknown indicating if the email is definitively real ## `status` (type: `string`): Technical status classification ## `reason` (type: `string`): The exact reason for the status ## `domain` (type: `string`): The domain of the email ## `hasMx` (type: `string`): Whether the domain has valid mail servers ## `microsoftConfirmed` (type: `string`): Whether Microsoft 365 confirmed the account ## `gravatarConfirmed` (type: `string`): Whether an active Gravatar profile was found ## `disposable` (type: `string`): Whether the domain is a known burner ## `roleAccount` (type: `string`): Whether it is a generic inbox (info, admin, etc) ## `catchAll` (type: `string`): Whether the domain accepts all emails # API You can run this Actor programmatically using our API.
