Email Verifier — Real SMTP Verification

Verify email addresses with real SMTP handshakes, catch-all detection, and deliverability scoring. Just upload your list and hit Start — no API keys, no setup, no third-party accounts needed.

Why this Actor?

Most email verifiers on Apify either:

• Only check DNS/MX records (can't confirm if the mailbox actually exists)
• Wrap paid third-party APIs (you pay their markup on top)
• Require you to bring your own API key from ZeroBounce, Tomba, etc.

This actor does real SMTP-level verification — we handle the infrastructure, you just upload your list.

What it checks

For each email address, the actor performs:

Output

Each email returns a clear, actionable result:

{
"email":"john.doe@company.com",
"verdict":"Valid",
"sendable":true,
"is_catch_all":false,
"is_role_account":false,
"is_disposable":false
}

Verdict values:

• Valid — Email verified as deliverable via SMTP
• Valid - Catch-all domain — Domain accepts all emails, so delivery is guaranteed but the specific mailbox can't be confirmed
• Valid - Role account — Shared mailbox (info@, hello@, support@) that is deliverable
• Likely Valid — Verification uncertain but no signs of invalidity
• Invalid — Email does not exist or is not deliverable
• Disposable — Temporary/throwaway email address
• Unverifiable — Could not determine (server timeout, etc.)

The sendable field is the key column — just filter on true to get your clean send list.

Input

Option A — Upload a CSV or TXT file: Upload a file with email addresses. The actor auto-detects emails from CSV columns or reads one email per line from TXT files.

Option B — Paste emails (one per line):

user1@example.com
user2@company.org
user3@startup.io
