Login Email Uniqueness
The Login Email of each traveller (profile), whether active or inactive, must be unique.
The Login Email of each traveller (profile), whether active or inactive, must be unique.
From time to time an agency may encounter a problem when creating a profile if the Login Email (address) provided is associated already with another profile in Kudos' database. This could be a profile for a company associated with your agency or a different one.
This usually occurs when a non-business email address (e.g. @gmail.com) is used.

As the Login Email must be unique for each profile, whether active or inactive, the agency could consider the following options.
If the traveller is no longer employed or travelling for a previous company, they could request the company or former agency to make their profile inactive (see sub-section below).
Use an email alias/alternative valid email of the user, or
Subaddressing as Gmail and other email providers allow i.e. inclusion of the "+" symbol
e.g. tony.stark+01@gmail.com, tony.stark+kudos@gmail.com (Google: email subaddressing), orA unique false email provided will never be matched to an email address whether it exists in Kudos' global database (DB) or not.
This option is not advisable as you never know if/when the "false email" may ever match a real one, as well as this information, is synced with integrated systems (e.g. GDS, OBT) which means suppliers and vendors (e.g. airlines, hotels) will be a recipient of fake info.
The agency would therefore be non-compliant with the IATA Resolution 830d (passenger contacts) mandate, and
An airline potentially now or in the future could issue an ADM (Agency Debit Memo) if mishandling of the passenger resulted (e.g. missed flight).
