You can import an LP template, just save the html file and use the import tool. For email just copy and paste
Hey Tara, have you requested that support enable the feature that allows you to import from your Sandbox to your Production instance? This is something that they can do if you open a support ticket.
But, as Jamie mentioned, if it's an email template you can just copy the HTML and paste it into a template in your production instance.
Once you have requested the link that Dory Viscogliosi mentioned above, the way to actually move programs is such:
1. Log in to production Marketo and go to the home page and click on the “New” dropdown and import program as seen below.
2. Choose your subscription as the Sandbox instance and the Program will be “US New Member Form Update Recommendation"
3. Click next
4. For step 2 of the import program screen, choose where you’d like to clone the program to and make sure the check box is checked for using default conflict rules — as shown below. I would recommend putting the program in the Data Management folder
5. Click next, then import.
6. Pending there were no issues, it should be in the folder you directed Marketo to clone it to.
