Email Verifier, Finder & Deliverability Checker

Verify known emails, find publicly listed business contact emails, and audit domain email authentication in one batch. The Actor exports transparent MX, SPF, DMARC, DKIM, provider, disposable, role-account, and confidence signals without treating MX records as proof that a mailbox exists.

Who is it for?

Sales operations teams, lead-generation agencies, recruiters, founders, and developers can use this Actor to qualify public business-contact data and diagnose domain email setup before outreach.

What you can do

• Clean CRM and lead-list emails before outreach.
• Find a named person's email when it is publicly listed on the supplied company website.
• Audit company domains for mail routing and authentication gaps.
• Separate invalid, risky, ready, not-found, and domain-only results.
• Process up to 10,000 deduplicated targets with bounded concurrency and resumable cutoff evidence.

Example input

{
  "emails": ["sales@example.com", "person@company.com"],

Input settings

At least one target is required. Inputs are deduplicated before network work.

Input recipes

Verify a pasted list

{ "csvText": "hello@example.com\nsales@example.org" }

Audit domains

{ "domains": ["google.com", "microsoft.com"] }

Find a public contact email

{ "contacts": [{ "firstName": "Jane", "lastName": "Smith", "domain": "example.com" }] }

Limits and data availability

• The maximum batch size is 10,000 unique targets; finder mode checks a bounded set of public company pages.
• Results depend on public DNS and website availability. Missing public evidence produces NOT_FOUND rather than a guessed address.
• A valid format and MX record do not prove that a specific mailbox exists.
• isVerified: null and isCatchAll: null mean the claim was not conclusively tested, not false.
• DKIM selectors are chosen by each sender; common-selector discovery is useful but not exhaustive.
• Public contact discovery returns only an address found on the supplied company's public pages and textually matching a conventional person pattern.
• DNS changes can take time to propagate; use checkedAt when comparing runs.
• Large workloads may stop before the platform cutoff and preserve pending targets in the run key-value store.

API usage

curl -X POST "https://api.apify.com/v2/acts/fetch_cat~email-enrichment-scraper/runs?token=$APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"emails":["hello@example.com"]}'

JavaScript:

import { ApifyClient } from 'apify-client';
const client = new ApifyClient({ token: process.env.APIFY_TOKEN });
const run = await client.actor('fetch_cat/email-enrichment-scraper').call({ emails: ['hello@example.com'] });
const { items } = await client.dataset(run.defaultDatasetId).listItems();

Python:

import os
from apify_client import ApifyClient

client = ApifyClient(os.environ['APIFY_TOKEN'])
run = client.actor('fetch_cat/email-enrichment-scraper').call(
    run_input={'emails': ['hello@example.com']}
)
items = client.dataset(run['defaultDatasetId']).list_items().items
