The following features are included in the Spring '16 release. 

Email Insights

Email Insights is a brand new historical aggregate data email analytics experience — redesigned end-to-end for lightning fast performance based on the new Marketo Orion infrastructure, and a completely new user interface design optimized to fit the needs and workflow of Email Marketers. 

Email Template Picker

Create beautiful emails using our new Starter Templates! Also, quickly locate your templates from their live thumbnails.

Email Editing---Re-imagined

That’s right, a brand new email editor! Use lightweight drag-and-drop functionality to add and re-order content. New elements, including images, videos, variables, and modules, are sure to enhance your editing experience. Also check out the updated code editor, previewer, and preheader support.

Mobile In-App Messages

Create stunning in-app messages for your app right within Marketo. Define exactly who should see it and when with the in-app message program. Easily monitor its performance with the program dashboard.

No Draft Snippets

Gone are the days where you have to re-approve everything each time a snippet is updated! With No-Draft, all emails and landing pages using a snippet will get the snippet updates and maintain their prior statuses. Each time you approve a snippet, you’ll have a choice to run No-Draft and update everything, or create drafts. It’s up to you! No-Draft will be available to all customers and controlled by a new permission in Admin. 

Custom Activity Definition Modeler

Marketo admins can now define and manage their custom activity types via the Marketo Custom Activity Definition modeler. Similar to (and in conjunction with) the Marketo Custom Object Modeler, admins can now extend the data model to suit their exact business needs. Details on how to use this functionality is available on the Marketo documentation site.  

Landing Page, Landing Page Template, and Form APIs

The Marketo REST APIs now support control over Marketo landing pages, landing page templates, and forms. Users can now create, update content, approve, and delete these assets directly via the Marketo REST API. 

Details on these APIs and how to use them are available on the Marketo Developers site.

IP Whitelisting for API Access

Similar to the IP whitelisting feature for Marketo user logins, Marketo admins can now set up a whitelist of IP addresses that can access the Marketo SOAP and REST APIs, thereby blocking access from non-authorized IP addresses.  This provides an added layer of security to your Marketo instance, and ensures that API access can only occur from within your organization’s network.  Details on how to set this up are available on the Marketo documentation site.

Friendly Instance Name

Today, it’s hard to differentiate between Marketo instances, for example, sandbox and production instances. This feature lets you know which instances you're currently working on. 

Limited Time Access

Today, users are invited to Marketo subscription for an indefinite period of time. This feature enables admins to invite users to subscriptions for a limited period of time, for example, 2 weeks or 1 month.
