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 10.4 - 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.

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, 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.

MailChimp 10.0 - February 19, 2015

In 10.0, you'll find helpful new tools in the main navigation bar, the Campaign Builder, and when you create segments.

Throughout MailChimp, you'll see a Help tool in the top navigation bar, next to your profile name. Click Help to browse, search, or open Knowledge Base articles right in your browser or tab. Learn more about the Help tool.
Top navigation bar shows cursor hovering over Help link.

If you've been sharing videos in your campaigns with merge tags, you'll be happy to know we've created a new content block to make this easier.

Once you drag the Video Content Block into your campaign layout, you'll input the video source URL, upload a thumbnail image to display in your campaign, and add an optional caption. If your video is hosted on YouTube or Vimeo, the content block will even create a default thumbnail image to use in the campaign.
