Email Normalization
Validate email format and standardize to lowercase.
Email addresses are case-insensitive, but inconsistent capitalization can cause duplicate entries in databases and CRM systems. Email normalization ensures all addresses use lowercase and have valid formatting.
Email (Lowercase)
Converts all email addresses to lowercase and validates the format. Emails must have an @ symbol and a domain with a valid top-level domain (like .com, .org). Invalid emails are flagged.
