A Developer's Guide to the Email Validator

The Email Validator is a simple tool designed to check whether one or more email addresses are syntactically correct. It's a first-line-of-defense tool for cleaning data or validating user input on a form.

Note: This tool currently only checks for valid email address syntax (i.e., if it looks like an email address). It does not check for the existence of the domain (MX records) or whether the mailbox is disposable.

Features

• Bulk Validation: Check multiple email addresses at once by entering one per line.
• Syntax Checking: Uses a regular expression compliant with common email formats to validate the structure of each address.
• Clear Results: Each email in the list is clearly marked as having "Valid Syntax" or "Invalid Syntax".
• Instant Feedback: The validation process is fast and provides immediate results after you click the button.

How to Use

1. Enter Emails: Paste or type one or more email addresses into the input text area. Make sure each email is on a new line.
2. Click Validate: Press the "Validate" button.
3. Review the Results: A list will appear below showing each email you entered.
   • Green "Valid Syntax" Badge: The email follows a standard format like user@example.com.
   • Red "Invalid Syntax" Badge: The email is missing an @ symbol, has invalid characters, or is otherwise malformed.
