Vanity Email, Alias and Url

Summary:

How these three options are displayed and how they actually work

Dear Colleagues,

I have read the product documentation and I see that you can request the Vanity URL/Email feature in Controlled Availability in 21C.

Instead of the vanity email you can use an alias (Display Name field), for which you don't need to configure the SPF.

In the case of the vanity email I imagine that the communication to the candidate arrives as [email protected] 

If the alias is used instead the result would be CUSTOMER ALIAS + <career site URL>. Could someone confirm if this is correct?
