Email Verifier & Validator

Bulk-check email lists before your next lead-generation, outreach, or CRM cleanup campaign. The Actor validates address syntax, identifies common free and disposable providers, detects role-based mailboxes, resolves MX records, and assigns an easy-to-filter deliverability score and status.

Run it from n8n, Make, or Zapier, or on an Apify Schedule / API, to verify every new lead list before outreach.

The Actor uses Node.js DNS resolution and a built-in disposable-domain list. It requires no API key, paid data provider, or proxy.

Input

Field	Type	Required	Default	Description
emails	array of strings	Yes	Sample list	Email addresses to validate.
checkMx	boolean	No	true	Resolve mail exchange records for syntactically valid domains.

Example input:

{
  "emails": [
    "jane.doe@gmail.com",
    "ceo@stripe.com",
    "noreply@disposablemail.com",
    "bad@@format"
  ],
  "checkMx": true
}

Output

Each input email produces one dataset row containing:

• The original email, lowercase-and-trimmed normalizedEmail, domain, and localPart
• syntaxValid, mxFound, and the highest-priority mxHost
• isFreeProvider, isRoleBased, and isDisposable flags
• An integer deliverabilityScore from 0 to 100
• A status of deliverable (70–100), risky (40–69), or undeliverable (0–39)

Example output:

{
  "email": "jane.doe@gmail.com",
  "syntaxValid": true,
  "normalizedEmail": "jane.doe@gmail.com",
  "domain": "gmail.com",
  "localPart": "jane.doe",
  "isFreeProvider": true,
  "isRoleBased": false,
  "isDisposable": false,
  "mxFound": true,
  "mxHost": "gmail-smtp-in.l.google.com",
  "deliverabilityScore": 100,
  "status": "deliverable"
}

Scoring

Every address starts at 100 points. Invalid syntax subtracts 100, no MX record subtracts 60, a disposable domain subtracts 50, and a role-based local part subtracts 10. The final score is clamped to 0–100.

MX records confirm that a domain accepts email routing, but they cannot guarantee that a specific mailbox exists. Use the score as a practical screening signal rather than proof of inbox delivery.

How to use Email Verifier & Validator

1. Open Email Verifier & Validator on Apify Store and click Try for free.
2. Fill in the input (the form is prefilled with a working example) and click Start.
3. Watch results appear in the Output tab, then download them as JSON, CSV, Excel or HTML, or read them through the API.
4. Optional: save the input as a task and add a schedule to run it automatically, or connect it to your tools with integrations and webhooks.

How much does Email Verifier & Validator cost?

This Actor uses pay-per-event pricing: you pay only for what it delivers, and platform usage is included.

Event	Price
Result (one dataset item)	$0.001 each ($1.00 per 1,000)
Actor start	$5e-05 per run

Set Maximum cost per run in the run options to cap your spend; the Actor stops when the limit is reached. Check the Pricing tab for current prices and plan discounts.

Use Email Verifier & Validator with AI agents (MCP)

Give Claude, ChatGPT, Cursor, VS Code or any MCP client this Actor as a tool through the hosted Apify MCP server. The agent sees the input fields with descriptions and example values, runs the Actor, and reads the results.

MCP server URL (this Actor only):

https://mcp.apify.com/?tools=technicaldost/email-verifier

Claude Code:

$claude mcp add --transport http apify "https://mcp.apify.com/?tools=technicaldost/email-verifier" --header "Authorization: Bearer YOUR_APIFY_TOKEN"

Cursor, VS Code, Claude Desktop and other clients (mcp.json or the client's MCP settings):

{
  "mcpServers": {
    "apify": {
      "url": "https://mcp.apify.com/?tools=technicaldost/email-verifier",
      "headers": { "Authorization": "Bearer YOUR_APIFY_TOKEN" }
    }
  }
}

Clients that support sign-in (such as Claude.ai connectors) can use the URL without a token and log in to Apify instead. Get your token in Apify Console → Settings → API & Integrations, or generate a ready config for your client at mcp.apify.com. In the agent the tool is named technicaldost--email-verifier; ask it, for example, to "run Email Verifier & Validator with {"emails": ["jane.doe@gmail.com", "ceo@stripe.com", "noreply@disposablemail.com", "bad@@format"], "checkMx": true}".

AI agents without an Apify account can also run and pay for this Actor per request with x402 agentic payments.

Run Email Verifier & Validator via API

Run the Actor and get its results in one call (replace YOUR_APIFY_TOKEN):

curl -X POST "https://api.apify.com/v2/acts/technicaldost~email-verifier/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"emails": ["jane.doe@gmail.com", "ceo@stripe.com", "noreply@disposablemail.com", "bad@@format"], "checkMx": true}'

Python (pip install apify-client):

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("technicaldost/email-verifier").call(run_input={"emails": ["jane.doe@gmail.com", "ceo@stripe.com", "noreply@disposablemail.com", "bad@@format"], "checkMx": true})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

JavaScript / TypeScript (npm install apify-client):

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_APIFY_TOKEN' });
const run = await client.actor('technicaldost/email-verifier').call({"emails": ["jane.doe@gmail.com", "ceo@stripe.com", "noreply@disposablemail.com", "bad@@format"], "checkMx": true});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

Long runs: start them with POST /v2/acts/technicaldost~email-verifier/runs and fetch the dataset when the run finishes, or receive a webhook.
