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:

Check	Description
SMTP Handshake	Connects to the mail server and checks if the mailbox exists
MX Records	Verifies the domain has valid mail exchange records
Catch-All Detection	Identifies domains that accept all addresses
Disposable Detection	Flags temporary/throwaway email providers
Role Account Detection	Identifies generic addresses like info@, admin@, support@

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

Configuration

Parameter	Default	Description
`concurrency`	10	Parallel verification workers (1-50)
`timeoutSeconds`	30	Timeout per email verification (5-120)
