By default the ClickDimensions email marketing component sends emails to the email address 1 field on the CRM Lead and Contact records. However, we have now added the capability to allow you to specify which email address you want used.
This requirement came about because a large client of ours stores the email addresses of each Contact’s assistant in the email address 2 field. Some of their emails need to go to the Contact him/herself while others need to go to the Contact’s assistant. Of course, you could use this in a number of other ways.
Note that the newly added Email Address Field is not required. If you do not set it we will use the email address 1 field by default.
