Verify Email Address — Check If It's Real

Not all email addresses are real. Verify any address in seconds to find out if it's deliverable, risky, or a throwaway — before you send, import, or act on it.

10 free verifications per day · No signup required

What Mailbeam checks

Every verification runs 7 checks in parallel and returns a structured result in under 100ms.

SMTP mailbox confirmation

Goes beyond syntax — actually contacts the mail server to verify the specific mailbox exists.

Deliverability status

Returns Deliverable, Risky, Undeliverable, or Unknown — not just valid/invalid — so you can make nuanced decisions.

Typo correction

Catch common misspellings like 'gmial.com' and suggest the correct domain before the user submits.

Disposable email detection

Identify throwaway email addresses from Mailinator, YOPmail, and 50,000+ other services.

Free tool available

Verify individual email addresses without an account using the free verifier. Up to 10 per day.

API for developers

Integrate email verification into your application with one REST endpoint and official SDKs.

How it works

1

Enter or submit the address

Input the email address manually into the free tool, or submit it programmatically via the API.

2

Multi-layer checks run

Syntax, MX record, SMTP handshake, disposable database, role prefix, and catch-all detection all run in parallel.

3

Score calculated

Each check contributes to a 0-100 deliverability score. The overall status (Deliverable / Risky / etc.) is derived from the score and check results.

4

Actionable result returned

You receive the status, score, individual check results, and any typo suggestion — ready to act on in your product or campaign.

When to use it

Before sending an important email

Verify a key contact's email before sending a proposal, invoice, or important communication.

Validating form submissions

Run verification on every email submitted through your signup, contact, or lead capture forms.

Checking a suspect address

Use the free tool to manually investigate an email address that looks suspicious or was flagged as bounced.

Data entry validation

Verify emails as they are entered into CRM fields or spreadsheets to prevent bad data at the source.
