You can easily give access to your team to contribute to your newsletter. They will have access to all features that you have apart from sending the final newsletter unless you make them an 'admin' of your newsletter.
To give access to your team member, go to your newsletter "Settings -> Team" and enter their name and email. We will send them an invite or give them access if they already have a Goodbits account.
This feature is great to give those the ability to use our Chrome Extension to queue up content for the next newsletter.
