Email Validator
Check whether an email address is syntactically valid. It does not verify the mailbox.
Results appear here.
What the result means
The result is valid or invalid, with a short reason for that judgement. Valid means the address passed a practical syntax check: no spaces, a single at-sign, a local part, and a domain that has a dot and no empty labels. Letters, digits, and a small set of punctuation are allowed, and a plus sign in the local part is allowed, so plus addresses pass. The check does not prove that a mailbox exists, that mail will be accepted, or that the domain publishes an MX record. There is no SMTP conversation and no lookup of any kind. Quoted local parts and raw IP domains are rejected even though a strict reading of the mail standard sometimes allows them.

Questions
Does valid mean the inbox exists?
No. Valid means the syntax check passed. It does not prove that the mailbox exists, that the domain accepts mail, or that anyone reads it. The page never contacts a mail server.
Are plus addresses allowed?
Yes. A plus sign is allowed in the local part, which is the usual way to write a plus address. The check does not ask whether a provider routes the tag after the plus. It only accepts the character.
Why was a quoted name or an IP domain rejected?
This is a practical shape check, not the full mail standard. Quoted local parts, comments, and domains written as raw IP addresses are rejected. Use a plain local part and a hostname that contains a dot.
