Hi Partner
Do you want get account or contact related to the selected Quotes?

The ‘Potential Customer’ field type is customer, which value from Account and contact two entities, so which type the quote selected is very import.
You can refer following steps:
1.Add ‘Get record’ step.

2.Add ‘initialize variable’.

3.Add ‘condition’ to add a split based on the entity type in the “Customer-Field” do either load a contact or an account.

4.fill email ‘To’ field with the ‘email address’variable value.

Regards,
