## Questions

### Is removing dots always safe?

No. This implementation removes dots only for `gmail.com` and `googlemail.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.
