When entering user profile details in Gong, you can enter an alias email address in addition to your mandatory primary email address.
Primary email address
A primary email address generally shares the same domain as your company, for example email@example.com is employed by company ABCD with the same domain: www.abcd.com. Meaning there is a direct correlation between the domain of the company and the domain of the user.
When a user participates in a call using their primary email address, it is less complex for Gong to authenticate the user, and less complicated to map the user to a company because they share the same domain. By leveraging the domain information Gong can quickly determine if a meeting is an external meeting or an internal meeting. For example, if all the meeting participants share the same email domain (@abcd.com) as the company domain (www.abcd.com), then it's a safe bet to assume the meeting is internal. Likewise, if meeting participants have a mixture of domain endings then Gong would naturally assume the meeting is external.
This simplistic approach to mapping works great if everybody in a company only ever uses one email address, and each email address has the exact same domain as the company. But what happens if a company has two domains, for example www.abcd.com and www.abcd.co.uk? How does Gong map a user to a company when the user has two email addresses? For example, an IT worker may have a company email address which includes their first name and surname (firstname.lastname@example.org), but the same IT worker may also have a secondary company email address according to their jobtitle (email@example.com). To resolve these issues (mapping and authentication), Gong allows you to enter multiple alias email addresses in a user's profile.
Alias email address
An alias email address is a secondary email address that can be used in addition to the primary email address. When a user's profile contains additional email addresses, Gong maps the addresses to the user's primary email address. Therefore, when participants join a meeting with a mixture of different email domains, Gong can still determine if the meeting is external or internal. In addition, by associating multiple emails to a primary email, Gong can optimize the process of authenticating users.
When to use additional or alias email addresses:
A user has multiple email addresses belonging to the same company, corporation or entity
A user has multiple email addresses that need to be associated to the user's primary email address
Never ever use a personal email address as an additional or alias email. A user's profile should only ever contain company email addresses.
