An email validator performs a syntax check of an email address to ensure it uses the correct standard format. Validators typically use a regular expression (regex) algorithm to determine if the characters in the address match the allowed characters dictated by the expression. An email verifier takes this process further by confirming that the email address and the domain exist and are in use. Verification is typically done with SMTP checks (domain pinging), DNS record lookups, and other proprietary checks, depending on the tool.
