Bulk Email Verifier & Validator: Catch-All Check

Bulk email verifier and email validator for Apify. Paste a list of addresses, or pipe in a dataset from any scraper, and get one row per email: a safe, risky, invalid or unknown verdict, catch-all and disposable flags, role and free-provider detection, typo suggestions and a 0–100 quality score. Check whether an email is valid without sending anything. No API key, no extra account, no setup.

What does this email verifier do?

It runs each address through syntax, MX and live SMTP checks, then tells you whether the mailbox can receive mail. Use it to clean an email list before a campaign, validate scraped leads before they reach your CRM, or score contacts by quality. The verification engine is built by Verifox.

• Real SMTP checks, not just a syntax or MX lookup.
• Catch-all deep check on accept-all Gmail and Microsoft domains. In realtime mode the Actor waits for it and retries a risky catch-all once.
• Disposable and role detection to drop temp-mail addresses and shared inboxes such as info@ or sales@.
• 0–100 quality score to rank and threshold a list.
• Reliable by default: automatic retry and backoff on rate limits and temporary errors, and every address gets a row.
• Up to 100,000 emails in one bulk job.

How to verify emails in bulk

1. Click Try for free.
2. Paste your emails into the Emails field, or map an email field from another Actor's dataset.
3. Click Start.
4. Download the results as CSV, Excel or JSON, or read them through the API.

Duplicates are removed before verification, so each unique address is checked once. Run time depends on list size and on how many domains are catch-all.

How much does email verification cost?

From $4.00 per 1,000 results ($0.004 per email), with lower prices on higher Apify plans:

Apify plan	Price per 1,000 results
Free, Starter	$4.00
Scale	$3.50
Business	$3.00

Each run also has an Actor start event of $0.00005. There are no platform compute charges on top, so the cost is list size × rate. You can cap any run with Maximum cost per run.

Each address produces one result. A row where an address could not be checked (ok: false) is still a result and is charged the same way.

Apify's free plan includes $5 of monthly usage, which covers about 1,250 emails at this price.

Use it as an email verification API

Call the Actor from your own code with the Apify API. This request runs it and returns the results:

curl -X POST "https://api.apify.com/v2/acts/verifox~verifox-apify/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"emails": ["jane@example.com", "sales@example.org"]}'

• Chain it after a scraper: map the email field of any lead scraper dataset into emails.
• Automate it: schedule runs, or connect it to Make, n8n, Zapier and other tools through Apify's integrations.
• Use it from an AI agent: call it through the Apify MCP server in Claude, Cursor and other MCP clients.

Use cases

• Clean an email list before importing it into a CRM or outreach tool.
• Protect sender reputation by removing invalid and disposable addresses before a cold email campaign.
• Validate scraped leads from LinkedIn, Google Maps or directory scrapers.
• Score and segment contacts with the 0–100 quality score.

FAQ

How do I check if an email address is valid? Paste it into the Emails field and start the run. The reachable field tells you whether the address is safe, risky, invalid or unknown, and isValid gives a yes or no.

Does verification send an email? No. The checks stop before any message is sent, so the person never receives anything.

What is a catch-all email? A catch-all domain accepts mail for any address, so a plain SMTP check cannot tell whether one mailbox exists. The smtp.catchAll field flags these domains. In realtime mode the Actor runs a deep check on them to reach a firmer verdict; a result can still stay risky.

What is the difference between an email verifier and an email validator? Most people use the terms interchangeably. Validation usually means format and domain checks, while verification also tests the mailbox over SMTP. This Actor does both.

Do I need an API key or a separate account? No. You only need an Apify account. Verification is fully managed.

How many emails can I verify at once? Up to 100,000 in one bulk job. Above 500 emails, auto mode switches to bulk.

What happens if an address can't be checked? You still get a row, with ok: false and the reason, so nothing is dropped from your list.

Something isn't working. What should I do? Open an issue on the Issues tab with the run ID and we will look into it.
