Questions

Email Normalizer FAQ

What does the Email Normalizer do with plus-addressing tags?
It strips the plus sign and everything after it from the local part of the email address, converting plus-addresses to their base form.
How does the tool handle Gmail dot insensitivity?
It removes or normalizes dots in the local part of Gmail addresses, since Gmail treats dots as insignificant and delivers mail to the same address regardless of dot placement.
Can the normalized email be used for sending messages?
The tool produces a canonical format for data consistency; it does not verify deliverability or validate whether the address actually exists.
Is there a limit on how many emails can be normalized at once?
The material does not specify batch processing limits; users should check the tool interface for any restrictions on bulk input.
