Email Validator – bulk email syntax and MX check

Paste in a list of email addresses and get back one row per address with a verdict you can filter on. Each row says whether the address is well formed, whether its domain can receive mail, whether it is a disposable or role address, and what the likely typo fix is.

No email is sent and no mailbox is contacted. The check uses a syntax test and public DNS lookups only. Schedule it to clean new lists on a regular basis.

Why this one

• No emails sent. It does not send mail and does not probe SMTP servers, so it can't hurt your sender reputation.
• Five checks per address. Syntax, DNS MX lookup (with A record fallback per RFC 5321), disposable domains, role accounts such as info@, and typo suggestions.
• A clear verdict. The status field is valid, risky or invalid, and reason tells you why.
• Duplicates removed. Repeated addresses are dropped, ignoring case, so you don't pay twice.
• Fair pricing. $43.10 per 1,000 results, and runs with no results cost nothing.

Quick start

{
  "checkMx": true,
  "emails": [
    "info@example.com",
    "john.doe@gmial.com",
    "test@mailinator.com"
  ],
  "maxEmails": 5
}

This returns one row per unique address, with its status, reason and any suggested correction.

How to use it

1. Click Try for free.

3. Set Maximum emails to cap the run, from 1 to 10,000. The default is 1,000.
4. Leave Check DNS MX records on to look up mail servers for each unique domain. Turn it off for a syntax-only check.

Good to know

• A valid status is not proof of a mailbox. It means the address is well formed and the domain can receive mail. The specific mailbox is never contacted.
• Limit of 10,000 addresses per run. Set by Maximum emails.
• Data source. Public DNS lookups and a bundled list of known disposable domains. The list is not exhaustive.
• Only your addresses are processed. Nothing is collected from other websites. Make sure you have a lawful basis to process the addresses you submit.
• Not affiliated. This tool isn't affiliated with or endorsed by any email provider.

FAQ

Does it send emails to check them? No. It never sends mail or talks to mail servers directly.

Does it catch typos? Yes. For common providers it suggests a fix, for example gmial.com to gmail.com, in the suggestion field.

What is a role account? An address like info@, sales@ or support@ that usually goes to a team, not a person.
