What’s New in MailChimp

Does a feature in MailChimp look different from the last time you used it? We update the MailChimp application every month or so to add new features and improve existing ones.

This article provides a high-level overview of what we've done in each update. You'll find descriptions of new or updated features, along with links to our Knowledge Base articles that explain how to use them.

MailChimp 10.6 - November 18, 2015

Our 10.6 release brings additional powerful features for MailChimp Pro users, as well as feature refinements that everyone can enjoy.


We're constantly working to make Automation more powerful and intuitive. With this release, we've redesigned the List and Workflow step into a split-pane layout, to make it easier to find the workflow you want. We've also included the option to set post-sending actions, which will allow you to automatically manage some list data for subscribers based on their interaction with an email in the workflow.

Learn how to use these new Automation features when you create your workflow.

RSS-Driven Campaigns

Previous to this release, we'd bring in content to your RSS Campaign as it appeared in your feed. This meant that if the images in the feed were gigantic, your template would stretch to fit the image. Now you can choose to have us automatically resize your images to fit your template width.

Learn more about using this feature in your RSS Campaign or when you add a blog post to a regular campaign.

New Pro Features

Users who have the MailChimp Pro add-on in their accounts will see several new exciting features.

  • Advanced segmentation to more precisely target subscriber sets
  • 50 additional merge fields to store more subscriber list data
  • Timewarp for Automation workflows to send emails based on each recipient's time zone
  • Inbox Preview to see how campaigns will look in different email clients

MailChimp 10.5 - September 14, 2015

MailChimp 10.5 brings some significant changes to the Automation Builder and a handy new way to pay with PayPal. 


The Automation Builder has been reorganized to give you greater control over when you send each automated email in your workflow, and to which subscribers. Now, when you design your email in the Email Builder, you'll also have the option to configure delivery settings for individual emails and segment the subscribers who receive them. 

Learn more about Automation.

Pay with PayPal

Many users have requested an alternate way to pay for their MailChimp accounts and add-ons, so we've added PayPal functionality to billing. To change your preferences, click your Profile Name and choose Account. When you edit your payment method, you'll be prompted to sign into PayPal and that's it!

More Tools

We also rolled out some other pretty neat tools and features recently, including MailChimp Pro and a new MailChimp Subscribe app for iPad and Android.

MailChimp Pro is an account add-on, which offers a set of advanced features for business like Delivery Insights, Compliance Insights, Multivariate Testing, Comparative Reporting, and even the ability to cancel a campaign send. 

MailChimp Subscribe is a new and improved version of our mobile signup app, Chimpadeedoo. We'll continue to support Chimpadeedoo for a little while, but we encourage you to check out Subscribe and see what's new.

MailChimp 10.4 - August 10, 2015

In this release, we made the list import process and A/B Testing Campaigns more intuitive and robust. Additionally, Pinterest users will be excited to see that we now have a Pinterest Social Card and a Social Share option.

List Import

You may notice that the list import process looks a little different. Because list import is the first thing many new users do in MailChimp, we wanted to make it as clear as possible. The list import process now walks users through each step with a Confirm step at the end to review the import before subscribers are added to the list.

A/B Testing Campaign

A/B Testing Campaigns are an updated version of the old A/B Split Campaign. Now you can test up to three different variations of a single variable. Test your subject line, from name, send time, and even content.

Incorporate A/B Testing Campaigns into your email marketing plan to see how small changes to your campaign content can impact your results.

Update Static Segment

If you ever needed to create a large static segment in the past, you know it’s not always easy if you have a lot of email addresses. Now you can create a static segment from a file import.


We want to make sure you can share your campaign on all your social channels, and now we've added a way to do that with Pinterest. Use our Social Cards feature to control how your campaign will appear when shared on Pinterest. Additionally, the Social Share content block includes a Pinterest icon, so your subscribers can share your campaigns on Pinterest.

MailChimp 10.3 - June 22, 2015

For 10.3, we redesigned and reorganized parts of our Account and Billing sections. 


With the goal of streamlining your experience in MailChimp's Account section, you'll find a basic Overview page, and familiar account options under the Settings tab, like Details, Users, and Security. MonkeyRewards and Partner Discounts are available in the Extras menu. 

In the Billing section, you'll see your pending purchases in a sidebar along with currency options and saved credit card information. When you add a Monthly Plan, Pay As You Go credits, or other add-on features to your cart, they'll appear in this area. When you're ready to check out, just click Complete Purchase and you're done!

You can still edit or remove your credit card information from the Billing information page, or right in the sidebar where you make your purchase. To change the currency that appears in the sidebar, click the $ US Dollars drop-down menu and choose your preferred currency.


MailChimp 10.2 - May 4, 2015

This release brings small user interface changes to improve your experience with MailChimp, along with a pretty major overhaul of the look and feel of our Knowledge Base.

MailChimp Updates

In addition to small text and label tweaks, we've made it possible for you to rename sent campaigns. You'll find groups more easily in the segmentation criteria menus on Lists and Campaign pages as well.

Knowledge Base Changes

The Knowledge Base redesign is something we're excited to share with you. The layout and typography look more like what you see inside the MailChimp application, and we've made the site easier to use and navigate.


We updated our printable layouts, so article pages will look nice and clean the next time you try to print a copy.

Search Results

Search results have been organized into filtered types: Articles, Quick Answers, and Glossary entries. If you’re looking for a tutorial or troubleshooting guide, try the main Articles tab first. A definition? Click over to Glossary. To view all your search results, be sure to click the tabs to see what else is listed.

Site Navigation

On any category or article page, you can jump to sub-categories or In this article sections with a sub-navigation on the left side of the page. It will follow you as you scroll, and highlight the section you're in. We've also added breadcrumbs to the top of article pages, which tell you where in the Knowledge Base you are and make it easy to navigate back to pages you visited earlier.

MailChimp 10.1 - April 1, 2015

Our 10.1 release enhances a few processes, and gives you further control over your lists and forms.

New Template Layouts

Many of our users have requested new template layouts, and now you've got eight of them! Choose between 1:3:1, 1:3:2, 2:1:2, and 3:1:3 templates, in the regular and banded styles, in addition to the traditional layouts we've always offered.

Automation Workflows

Four new Automation workflow types are available to help you streamline your email marketing, including:

  • Date subscribed
  • Subscriber joins group
  • Subscriber leaves group
  • API trigger

Import Unsubscribed and Cleaned Addresses

You can now import directly into the Unsubscribed and Cleaned sections of your list, which is a huge help if you've moved to MailChimp from other ESPs or need to create a suppression list.

Subscriber Pop-up Form Settings

Further customize your Pop-up Signup Forms in the Form Builder by including maximum width, and font colors to improve readability.

List Field Defaults

We've added list field default settings to the List fields and *|MERGE|* tags page, so you don't have to edit your signup forms every time you need to make a small change. You can also change formats for your date and phone number fields on this page.

Billing Invoice Changes

Billing statements got a facelift and can be found in their new home, the Billing history page.
