Login Email Uniqueness

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), or
A 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).

What is Email Sub-Addressing?

Email sub-addressing, also known as "plus addressing" or "tagged addressing," is a technique that allows users to create multiple, unique email addresses with a single base email account. This is done by appending a 'tag' or 'modifier' to the local part of the email address, typically using a plus sign (+) followed by the tag, before the '@' symbol.

For example, if your base email address is john.doe@example.com, you can create sub-addresses like:

These sub-addresses will all route messages to the main email account (john.doe@example.com) while allowing you to easily filter, sort, or organize emails based on the tags used. It also helps in identifying the source of spam or unwanted emails if a specific sub-address was used only for a particular service or subscription.

Not all email service providers support sub-addressing, and the implementation might differ across providers. For example, Gmail uses the plus sign (+) for sub-addressing, while some other providers might use a different character, like a hyphen (-) or an equals sign (=). It is essential to consult your email service provider's documentation to understand if and how they support email sub-addressing.
