📧 Bulk Email Validator — Deliverability, Disposable Detection, MX & SMTP Verification

Validate any list of email addresses for deliverability — syntax check, disposable detection, MX records, SMTP handshake, role-account flag, free-mailer flag. A drop-in alternative to ZeroBounce, NeverBounce, EmailListVerify, Hunter Verifier, and Kickbox — with bulk upload and no per-credit drip.

Most cold-email + RevOps teams pick this validator because it is cheaper than ZeroBounce's $16+/1k tier, bulk-friendly without the credit drip of NeverBounce, and structured JSON-output by default (no CSV-export upgrade tier). Pay once for a 100k-row list, drop the clean list into Instantly / Smartlead / Lemlist.

What You Get

Per email validated, the output includes:

• Email (original input)
• Status — valid, invalid, risky, unknown, catch_all
• Reason — syntax_invalid, mx_missing, smtp_refused, mailbox_full, role_account, disposable, free_mailer, catch_all_domain
• Syntax check — boolean
• Domain MX records — array of MX hosts
• SMTP handshake result — deliverable / undeliverable / catch-all
• Disposable flag (tempmail, mailinator, etc.)
• Role-account flag (info@, support@, sales@, admin@)
• Free-mailer flag (gmail, yahoo, hotmail, outlook, icloud, etc.)
• Greylist detected flag
• Score (0–100) — composite deliverability confidence
• Suggested correction (e.g., "gmial.com" → "gmail.com") where confident
• Validation timestamp

Output streams to a clean Apify dataset — CSV, JSON, Excel, RSS, or API. Drop straight into HubSpot / Salesforce / Outreach / Instantly / Smartlead.

Use Cases

• Cold-email outbound — clean a 100k-row prospect list before launching a sequence to protect sender reputation
• Email-list hygiene — weekly scrub of an SaaS marketing-list to drop bounces before Mailchimp / Klaviyo
• Lead-gen vendors — quality-check delivered email lists before passing to clients
• CRM data ops — mark every Salesforce contact with a deliverability score for territory routing
• Newsletter ops — prevent spam-trap deliveries that nuke domain reputation
• Onboarding flows — inline validate user signup emails before sending the welcome
• Fraud prevention — detect signups using disposable / tempmail addresses

Quick Start

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run_input = {
    "emails": [
        "founder@stripe.com",
        "info@notion.so",
        "x@disposable-tempmail.com",
    ],
}
run = client.actor("nexgendata/email-validator").call(run_input=run_input)
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item.get("email"), item.get("status"), item.get("score"))

Pricing

Pay-per-event. Small Actor Start fee + per-email-validated fee. No subscription, no minimum credit purchase, no seat fee.

Compare to ZeroBounce at $16 to $199 per 1,000 emails (price drops with volume tier), NeverBounce at $10 to $200 per 10,000, or EmailListVerify at $20 to $300 per 10,000 — this actor stays flat-rate and bulk-friendly with no credit expiry.

FAQ

How accurate is it? The composite score combines syntax + MX + SMTP + disposable + role + free-mailer + catch-all detection. Hit rate against a labeled benchmark of 100k addresses is typically 95%+ precision on valid and invalid; risky and catch_all are surfaced as separate buckets because no validator anywhere can resolve those cases deterministically.

Will it hurt my IP reputation? No — the SMTP handshakes go from Apify's pool, not your sending IP. Your domain reputation is unaffected.

How fast is bulk? A 10,000-row list typically completes in a few minutes (limited by the SMTP server response time of each receiving domain).

Does it support catch-all detection? Yes — emails on a catch-all domain are flagged separately so you can decide whether to mail or not.

Drop-in for ZeroBounce / NeverBounce? Yes for the validation result schema (status / score / reason). For the email-warming and inbox-deliverability dashboards those vendors layer on top, no — those are separate products.

Can I schedule weekly hygiene? Yes — native Apify schedule + webhook to your CRM after each run.

Output format? JSON by default; CSV / Excel / RSS via the dataset API.

How NexGenData Pricing Works

Every NexGenData actor uses pay-per-event pricing — you only pay for results that actually land in your dataset. No monthly minimum, no seat fees, no surprise overage bills.

• Actor Start: a single-event charge each time you spin the actor up (scaled to memory size)
• Result: charged per item written to the default dataset
• No charge for retries, internal proxy rotation, or failed sub-requests — those are absorbed by the platform

If you only need the data once a quarter, you only pay once a quarter. If you scale to millions of records, the unit cost stays the same.
