Frequently Asked Questions
What does email validation check?
Email validation checks format (proper structure with @ symbol, domain, etc.), domain validity, and common email patterns. It verifies that an email address follows standard email format rules.
Does validation verify that the email exists?
Format validation checks the email structure but doesn't verify that the email account actually exists. To verify existence, you would need to send a verification email.
What email formats are supported?
The validator supports all standard email formats including standard addresses, plus addressing (user+tag@domain.com), and other valid email patterns.
Can I validate multiple emails at once?
You can validate emails one at a time. For bulk validation, process each email address separately or use the tool programmatically for multiple addresses.
