@DavidLa_2387925 The only way you can have her account on smarty with the same email is to add her to a group as a nickname account - I recommend this help article https://help.smarty.co.uk/en/articles/3406401-how-do-i-start-a-group . As far as I am aware, you will not be able to get the referral benefit that way....unless anyone else can chip in with different information.
However, if she has her own email, you can refer her first to get the referral benefit and then invite her to join your group - you should each get a discount on standard plans then.
