Connect the power of Litmus Extension directly to Oracle Responsys to streamline production, so you can drive better email results, faster. Learn more →

When it comes to email workflows, each team is unique—and so are the tools that help them get their campaigns out the door. Marketers can choose between hundreds of email service providers (ESPs) and dozens of code editors, localhosts, and task runners—and our research shows that many teams even use multiple of each of these tools. 

No matter which tools your team uses, we want to make sure that you can utilize Litmus to improve your campaigns and learn what content and tactics resonate best with your subscribers. That’s why Litmus is designed to work with any email tool, and to fit into your unique workflow.

Why connecting your marketing tools is the key to email success

We know that switching back and forth between tools can be a hassle. The more often you have to jump between different tools, the more time you lose—and the more likely it is for errors to creep in. When your marketing tools are connected, information seamlessly flows from one to the other so you can automate manual tasks, set your campaigns up for success, and make true improvements to your workflow. That’s why we’re set on a mission to integrate Litmus more seamlessly with your favorite email marketing tools. 

There is a whole set of integrations available with Litmus—each of them designed to automate manual steps that slow down your workflow and eliminate the risk of errors, so that your emails perform their best. Figure out which integrations can supercharge your team’s email workflow when we break them down one by one:

Stop copy and pasting your code from Litmus to your ESP with ESP Syncing

Getting your email from your code editor into your ESP has always been a hassle. And once your email is built, you need to get it from your ESP to your testing solution. It’s time to say goodbye to that manual copy and paste process.

With ESP Syncing, you can automatically sync your code from Litmus Builder to your ESP with a click of a button. Once connected, whenever you make any changes to your code in Builder, it automatically updates in your ESP, too. 

Once your email is complete and ready to test, use ESP Syncing to instantly begin testing your email across key spam filters to make sure it reaches the inbox and produces the best subscriber experience. 


This integration is for you if you use Litmus Builder to code and troubleshoot your emails and are looking for a way to eliminate the bothersome process of copy and pasting your code to your ESP. This integration is also for you if you’re looking for a more efficient way to import your emails from your ESP to Litmus for thorough pre-send testing.



If you’re on a Litmus Plus plan or above, you have access to ESP syncing with the following ESPs:

  • Campaign Monitor
  • Mailchimp

Litmus Enterprise plans come with access to ESP syncing for even more ESPs:

  • Acoustic Campaign (formerly IBM Watson Campaign Automation)*
  • Salesforce Marketing Cloud (formerly ExactTarget)
  • Eloqua
  • Marketo

* The Acoustic Campaign ESP Sync cannot currently be used for importing an email for testing.

Troubleshoot Your Emails Right Where You Build With the Litmus Extension

When you’re working with a local editor or your ESP’s email editor, email testing can be a cumbersome process. For example, you might build your email in your favorite code editor, then move it into Litmus for testing, and if you find an issue, the process starts all over again. That’s a lot of copying and pasting, and a lot of switching between tools. 

The Litmus Extension brings Litmus’ testing tools right into your favorite build environment. It’s a powerful Chrome extension that brings the power of Litmus Checklist and Email Previews wherever you build your emails. 


The Litmus Extension is for you if you use a local code editor (like Dreamweaver) or your ESP’s email editor to build your emails and are looking to bring the power of Litmus’ pre-send testing to your build environment.



The Litmus Extension is available on Litmus Plus plans and above. It works with all text editors, task runners, and localhosts, including:

  • Dreamweaver
  • Sublime Text
  • Atom
  • Coda
  • Brackets
  • Grunt
  • Gulp
  • Zurb’s Foundation for Emails
  • MJML
  • And really any editor you’re using!

Does your team use your ESP’s email editor to create emails? The Litmus Extension works with the following ESPs:

  • Campaign Monitor
  • Mailchimp

If you’re on a Litmus Enterprise plan, you can also use the Extension with the following ESPs:

Plus, if you’re working with dynamic content in Marketo, Salesforce Marketing Cloud, or Responsys, the power of the Litmus Extension lets you test multiple variations of your content in a single click as you build.

Use Litmus Email Previews inside your ESP

Litmus Email Previews are also integrated in hundreds of popular ESPs. While you won’t be able to use the full power of the Litmus Platform via these integrations—you typically only get Email Previews inside your ESP and can’t utilize the power of Litmus Checklist or Spam Testing for complete pre-send testing—it still is another great way to preview and test your emails right where you create them, without switching between your ESP and Litmus.


Litmus Email Preview integrations come in handy for everyone who’s looking to use the power of Litmus Email Previews within their ESP to compliment the full Litmus testing platform.


Direct integrations of Litmus Email Previews look different depending on the ESP (so you’ll have to check with your ESP for details), but check out this example of the Email Previews Integration within Salesforce Marketing Cloud:


Popular ESPs with Litmus integrated right into their services include

Pricing and usage limits differ from ESP to ESP. Please check your ESP’s help documentation to find out if Litmus Email Previews are integrated in your ESP, and to learn more about the pricing. 


Don’t use one of these ESPs? Don’t worry! No matter which email technology you use, Litmus can seamlessly integrate into your workflow. You can use Litmus alongside any of your existing email tools to create better email, faster, and increase your overall marketing effectiveness.
