Mailcheckers cannot currently confirm whether a specific inbox exists or accepts mail. You can still check an address’s format and inspect its domain’s public mail setup.
This page explains the current limits and points to checks that are available today. No email address is submitted to a verification provider from this page.
The email checker validates common syntax locally in your browser. This catches formatting problems, but a correctly formatted address may still not exist.
Domain health checks query public MX, SPF, DKIM and DMARC DNS records. Mail-routing records describe a domain’s configuration, not an individual mailbox.
We do not perform mailbox-existence or catch-all verification, connect to recipient SMTP servers, send test messages, or test inbox placement. No provider is called by this page.
Not right now. A syntax or domain DNS result is not proof that the specific inbox exists or can receive a message.
No. MX records identify mail exchangers for the domain. They do not establish that a particular recipient mailbox exists.
This page has no address input and makes no verification-provider request. On the free email checker, syntax is checked locally and only the domain is sent for DNS and disposable-domain checks.
