Bulk Email Verifier — Validate & Clean Email Lists

Verify and validate thousands of email addresses in bulk before you hit send. This actor is a fast bulk email verifier and email list validation tool that runs a full signal stack on every address and returns a clear status plus a deliverability score.

Use it to clean an email list after any scrape or purchase, cut your bounce rate and protect your sender reputation before outreach. Pass a list, a pasted blob or objects piped from another actor — export CSV, JSON or Excel.

What you get

For every email, one row with:

• email — the address checked
• status — valid · risky · invalid
• score — 0–100 deliverability score
• reason — why it landed in that status
• syntaxValid — RFC-style format check
• domain, hasMxRecord — MX/DNS lookup against clean public resolvers
• isDisposable — disposable / temporary domain (Mailinator, 10MinuteMail, Guerrilla Mail, YOPmail, and more)
• isRoleAccount — role address (info@, sales@, support@, noreply@, …)
• isFreeProvider — free provider flag (Gmail, Outlook, Yahoo, iCloud, …)
• didYouMean — typo suggestion (gmial.com → gmail.com)

A run summary with valid / risky / invalid counts is also saved to the key-value store as SUMMARY.

Status meaning

Status	Meaning	What to do
valid	Good syntax, domain has a mail server, not disposable/role	Safe to send
risky	Deliverable but lower quality: role account or MX-via-A fallback	Send with care / segment
invalid	Bad syntax, disposable, or no mail server	Drop it

Use cases

• Cold email & outreach — remove bounces before they hurt your domain reputation.
• Lead-list cleaning — validate scraped, exported or purchased lists.
• CRM hygiene — periodically re-verify your contact database to keep it deliverable.
• Signup / form validation — batch-check captured addresses for typos and junk.
• Agencies & SaaS — clean client lists at scale before every send.
• Deliverability protection — keep bounce rates under provider limits (Gmail, Outlook, Mailchimp, etc.).

Why this verifier

• No SMTP spam, no blacklisting — it does not hammer mailboxes on port 25 (blocked on most clouds and a fast way to get sending IPs blacklisted). It removes the bulk of undeliverable, junk and disposable addresses with safe, fast signals.
• Clean public DNS — queries resolve against public resolvers, so a dead domain reads as dead instead of being hijacked into a "parked" answer by a local resolver.
• Pipe-friendly — pass a plain list, a pasted blob, or objects piped from another actor (just set the email field name).
• Fast & parallel — bounded-concurrency DNS lookups with per-domain caching, so large lists with repeated domains fly through.
• Transparent — every signal is exposed as its own field, so you decide how strict to be.

How to use

1. Add addresses to Emails (list) and/or paste them into Emails (paste) (separated by spaces, commas, semicolons or new lines).
2. If you are piping objects from another actor, set Email field name (default email).
3. Tune Concurrency for large lists if needed, then run.
4. Export the valid rows to CSV, JSON or Excel, or pull them via the Apify API.

Example input

{
  "emails": ["business@mkbhd.com", "test@gmial.com", "hello@mailinator.com", "info@google.com"]
}

Example output

{
  "email": "test@gmial.com",
  "status": "invalid",
  "score": 10,
  "reason": "no_mail_server",
  "syntaxValid": true,
  "domain": "gmial.com",
  "hasMxRecord": false,
  "isDisposable": false,
  "isRoleAccount": false,
  "isFreeProvider": false,
  "didYouMean": "test@gmail.com"
}

How it compares

• vs. SMTP "ping" verifiers — connecting to mailboxes over port 25 is slow, often blocked by clouds, and risks blacklisting your sending IPs. This actor filters the vast majority of bad addresses safely — no risky probing.
• vs. paid SaaS verifiers — same core checks (syntax, MX, disposable, role, free, typo) on pay-per-result pricing with CSV/Excel/JSON export and full API access — no monthly subscription.
• vs. doing nothing — sending to an unverified list spikes bounce rate, damages domain reputation and lands future emails in spam. A quick verification pass keeps deliverability healthy.

FAQ

Does it confirm the exact mailbox exists?

It confirms the domain can receive mail (MX/A) and filters syntax, disposable, role and typo issues — the checks that remove the overwhelming majority of bounces — without the risky SMTP probing that gets sender IPs blacklisted. For most outreach, that is the right tradeoff.

Why is a valid-looking Gmail address marked risky?

Role accounts (info@, sales@, …) and addresses that only resolve via an A-record fallback are flagged risky because they have lower deliverability quality — not because they are necessarily bad. You decide whether to include them.

Can I feed it the output of a scraper?

Yes. Pass the dataset items as emails and set emailField. It pairs well with any lead- or email-scraping actor as the final step before outreach.

How many emails can I verify?

As many as you like. DNS lookups run in parallel with per-domain caching, so large lists with many repeated domains are processed quickly.

Can I export to CSV, JSON or Excel?

Yes. Every run produces an Apify dataset you can export to CSV, JSON, Excel, XML or JSONL — and a SUMMARY with valid/risky/invalid counts is saved to the key-value store.

How fast is it?

DNS lookups run in parallel with per-domain caching, so large lists with many repeated domains are processed quickly. Tune the concurrency input (1–50) to balance speed against your environment.

How do I verify an email list without SMTP?

This actor is a bulk email validation tool that runs syntax, MX/DNS, disposable, role and typo checks instead of probing mailboxes on port 25. You get a deliverability status and score with no SMTP connection and no blacklisting risk.

Is there a disposable email checker built in?

Yes. Every address is flagged with isDisposable, catching Mailinator, 10MinuteMail, Guerrilla Mail, YOPmail and many more temporary domains, so you can drop throwaway signups before sending.

How do I clean an email list and export to CSV or JSON?

Pass your list, run the verifier, then export the dataset to CSV, JSON, Excel, XML or JSONL — or pull clean rows via the Apify API. It works as a drop-in email list verifier API step after any scrape, signup capture or purchase.
