WordFly emails to Non-Primary email?

Hello WordFly users,

Does anyone send out campaigns to email addresses that are not the primary email?

We have a few cases were a customer may indicate that they want a certain e-mail subscription to go to a specific email address. The usual one is a teacher may want the education e-news to go to their work school email address, but keep their personal primary email for their login and ticket confirmations.

I understand that the approach would be to create an Output Set for use with WordFly that uses a custom element that pulls a specific email type and uses that if it exists, if not it would pull the primary email.

Has anyone tried this, or any other non-primary email campaign experiences?

Best,

Nicholas
