We need to be able to merge our alumni ID numbers in order for our audience to register for various platforms and benefits. It seems ridiculous that you can merge suffix 2 but there is no ID option. There are also no fields on the list which can easily be repurposed as and ID field (and if it could, it would create a lot of unnecessary work). Please add the ID field as a merge option!
The absence of Constituent ID as a merge field has stopped us from using NXT Email Marketing.
As a University, having the Constituent ID (Alumni Membership Number) as an email merge field is essential.
