How do I copy an email campaign between two accounts?

I am looking for an efficient or maybe automated way to forward email campaigns between different Constant Contact accounts. Right now, I am using this account to create and send emails to my mailing lists. I want my colleagues to efficiently be able to use the emails that I've created on my account and send them to their own mailing lists.

Does anyone have a suggestion on how to go about doing this? In the past we have just simply sent each other the templates of the email campaigns, I'm wanting to make it easier/faster to encourage my co-workers to want to quickly forward the campaign. 

Thank you!
