Knak Builder allows you to build complete emails before they are synced to Marketo so you don't have to perform any edits once the email is synced if you don't want to.
However we understand that sometimes editing an email in Marketo will be necessary. To help with that Knak has improved the way our emails are synced to make editing from within Marketo as easy as possible.
How to edit an email in Marketo
Navigate to Marketing Activities and select the folder and program where your email was synced too.
Click on Email Actions > Edit Draft
You will see your email load into the Marketo editor, each piece of content will be separated so it can be edited separately.
You can select a piece of content to edit by double clicking either the section itself or on any of the 'modules' on the right of the screen.
This will open a popup window in which you can edit that particular piece of content.
If you have buttons in your email these need to to be edited in a different way. In the bottom right corner of the edit screen you will see a button called 'Global variables'. Select that to bring up a sidebar in which you can edit the link and display text for all buttons in your email.
If you want to take advantage of this new editing functionality with emails already in Marketo you would need to resync those emails to see the changes.
This update should also resolve any issue with buttons not displaying properly in Outlook as described in this article.
