Email Verifier & Disposable Email Checker

Clean an email list in seconds and catch the addresses that will bounce or abuse your sign-up. For every address you get:

• Status: deliverable_domain, risky, disposable, undeliverable, invalid or unknown
• Risk: low, medium or high, with plain-English reasons
• Disposable check against 98,000+ temporary and throwaway domains, including subdomains. The list is rebuilt every hour and each run uses the latest one (listUpdatedAt says when)
• Typo fixes: jane@gmial.com comes back with didYouMean: jane@gmail.com
• MX records: does the domain exist and accept email at all (including RFC 7505 null MX)
• Role accounts: info@, support@, sales@ and 40 more shared inboxes
• Free provider flag: Gmail, Outlook, Yahoo, iCloud, Proton and others

Built by Kaidn, the fraud-scoring API, using the same email checks Kaidn runs on live sign-ups.

Use it for

• Sign-up and trial abuse: stop throwaway addresses before they claim a bonus or free trial
• List cleaning: drop dead domains and typos before a campaign, protect your sender reputation
• Lead quality: flag role accounts and free-mail addresses in B2B lead lists
• Fixing typos at scale: recover real customers who mistyped their provider

Input

{ "emails": ["sundar@google.com", "someone@mailinator.com", "jane@gmial.com"] }

Output

{
  "ok": true,
  "input": "jane@gmial.com",
  "status": "disposable",
  "risk": "high",
  "reasons": ["disposable / temporary email domain", "looks like a typo of gmail.com"],
  "didYouMean": "jane@gmail.com",
  "hasMx": false,
  "isDisposable": true,
  "isRoleAccount": false,
  "isFreeProvider": false
}

Export as JSON, CSV or Excel, or call it from the Apify API, Make, Zapier or n8n.

What it does not do

It does not connect to the mail server to ask whether one specific mailbox exists (SMTP probing). That is slow, often blocked, and can get the checking IP blacklisted. deliverable_domain means the domain is real and accepts email; it does not promise the exact inbox exists.

Pricing

You pay per address checked. Text that is not a valid address at all (invalid syntax), and addresses whose domain DNS gave no answer (status: unknown), are returned but not charged. Domains are looked up once per run, so big lists stay fast.
