We recently discovered the ability to send e-mails to constituents PLUS relationships attached to the record (including spouses!) in Online Express. But it turns out there's still no way to send an e-mail to both constituents and spouses in RE NXT unless they have their own separate record. In order for us to be able to use the marketing e-mail feature in RE NXT, we need to be able to select multiple address types (primary, work, etc.) and include spouses.
