Plus Addressing for duplicate Email Addresses
If you have multiple Customer Profiles with the same email address, another option is to use 'Plus Addressing' instead of disabling the duplicate email check.
'Plus Addressing' is a feature that allows you to create multiple distinct email addresses that all send to the same address.
This is done by adding a plus "+" symbol followed by a Tag (any word) before the at "@" symbol in the email address
