Email Normalizer applies a few text rules to one address per line. This is a convenience transform, not a universal canonical form. Different mail providers can treat the same spelling differently; never automatically merge user accounts based only on this output.
See what the tool changes
Paste John.Doe+news@Gmail.com into Email address(es). Normalised should show johndoe@gmail.com. The tool lowercases the address, removes the Gmail dots and +news, and changes googlemail.com to gmail.com too. Add First.Last+demo@example.com on another line: the output keeps the dot but removes +demo and lowercases the letters.
This tool removes everything after a + at every domain, even where the provider does not promise that this is an alias. It also lowercases the local part, which not every receiving system treats as interchangeable. For sensitive mail or account records, keep the original address and verify provider-specific rules separately. Do not paste real customer lists into screenshots or shared documents.

Questions you might have
- Is removing dots always safe?
- No. This implementation removes dots only for
gmail.comandgooglemail.com, but removes a+suffix for all domains. That second rule may also merge different addresses at some providers. Keep the original address; do not use normalized text as proof two people are the same.
