Screen one trimmed address with the workspace's simple pattern: non-space text, one @ separator, a dot in the domain portion, and at least two trailing non-space characters. Useful for form validation, data cleanup, and quick sanity checks before sending. Note: this is syntax checking only, not mailbox existence verification.

Use this as a quick UI-level syntax screen—not RFC 5322 conformance, DNS/MX lookup, mailbox existence, deliverability, ownership, or anti-abuse verification.

Step 1
One address without spaces matching ^[^\s@]+@[^\s@]+\.[^\s@]{2,}$ after trimming.
Step 2
There are no RFC mode, internationalization, DNS, or deliverability options.
Step 3
The status changes immediately to valid or invalid using a local regular expression.
Step 4
Treat success as a shape check and confirm ownership with a consent-based verification email in the real system.
Step 5
Use Regex Tester to inspect application-specific patterns, but avoid pretending a single regex implements all mail standards.
Consequence: Spaces, commas, angle brackets, headers, and URL syntax are tested as part of one string, so an otherwise usable address can be marked invalid.
Fix: Extract one bare address before checking it; parse address lists and mailto links with a standards-aware mail library.
Consequence: The local regex can accept a misspelled, unregistered, disposable, or nonexistent domain because it performs no DNS, mailbox, ownership, or delivery check.
Fix: Apply product rules separately and confirm ownership with a consent-based verification message in the real mail system.
Consequence: Quoted local parts, domain literals, single-label domains, and other legal forms fall outside this deliberately simple regex.
Fix: Use a standards-aware mail library and delivery verification for production acceptance.

It has non-space text on both sides of @ and a dotted suffix of at least two characters.

No; it makes no network request and cannot establish DNS, existence, ownership, or deliverability.
