Email Normalizer
Normalize and deduplicate email addresses by removing dots, plus aliases, and provider-specific suffixes to find canonical forms.
FAQ
Why are dots removed only for Gmail addresses?
Gmail ignores dots in the local part of an email address, so john.doe(at)gmail.com and johndoe(at)gmail.com deliver to the same mailbox. Other providers like Outlook treat dots as significant characters, so removing them would change the recipient.
What is plus-addressing and which providers support it?
Plus-addressing (also called sub-addressing) lets you add a +tag after your username (e.g., user+newsletter(at)gmail.com). Gmail, Outlook, and many other providers support this. Emails sent to the tagged address are delivered to the base address. This tool strips the plus-tag to find the canonical address.
How does Yahoo alias detection work?
Yahoo uses a dash-based system for disposable addresses. A Yahoo user can create aliases like username-keyword(at)yahoo.com. The tool strips everything after the first dash to find the base Yahoo address.
Does this tool validate whether an email address actually exists?
No, this tool only normalizes the format of email addresses based on known provider rules. It does not verify whether the mailbox exists or is active. Use a dedicated email verification service for deliverability checks.
