They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows. 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/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.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/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 High-speed, cost-effective pre-filtering tool designed to verify email address deliverability and status before routing lists through expensive premium verification platforms. From tools like Debounce, Zerobounce, Icypeas, Leadmagic, Lemlist, Neverbounce, MillionVerifier, Bounceban and others. By executing syntax, domain MX record, and SMTP mailbox availability checks, this tool categorizes emails into valid, invalid, or catch-all statuses to help optimize email marketing campaigns and maintain high sender reputation. ### FEATURES Syntax & Format Validation: Instantly checks if an email string adheres to standard RFC formatting rules (valid_syntax). MX & Domain Health Checks: Verifies that the destination domain (domain) has active Mail Exchange (MX) records configured to receive emails. Catch-All Domain Detection: Identifies whether a target domain is configured as a catch-all server (catch_all), accepting emails sent to non-existent addresses. Mailbox Status Diagnostics: Detects specific mailbox flags, including whether an inbox is full (inbox_full), disabled (disabled), or currently deliverable (deliverable). Cost-Optimization Pre-filtering: Filters out obvious bounces and invalid formats before uploading lead lists to paid verification services like DeBounce, ZeroBounce, NeverBounce, or BounceBan. ### USE CASES Lead List Cleansing: Pre-screen large cold outreach databases to discard invalid formatting and domain errors before running final verification passes. Form Registration Protection: Connect to signup workflows to block invalid or misformatted email submissions in real time. Sender Reputation Safeguard: Reduce hard bounce rates on cold email platforms (e.g., Lemlist, Instantly) by filtering out dead or disabled email addresses ahead of campaigns. Sales Intelligence Pre-Verification: Quickly segment contacts into definitive deliverable leads versus catch-all addresses to adjust sending strategies accordingly. ### OUTPUT ```json { "email": "dev@saswave.com", "status": "catch-all", "username": "dev", "domain": "saswave.com", "valid_syntax": true, "deliverable": true, "catch_all": true, "disabled": false, "inbox_full": false } ```` ### 🛟 SUPPORT Share your runs with the developer team and create issues on error to help us improve actor quality. You might discover edge case we didn't test yet We stay available anytime # Actor input Schema ## `emails` (type: `array`): Provide email list to find valid / invalid / catch-all status ## Actor input object example ```json { "emails": [ "dev@saswave.com", "dev@sasswave.com", "thomas@saswave.com" ] } ``` # Actor output Schema ## `results` (type: `string`): No description # 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": [ "dev@saswave.com", "dev@sasswave.com", "thomas@saswave.com" ] }; // Run the Actor and wait for it to finish const run = await client.actor("saswave/email-validation-tool").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 📖?
