Enhance Your Email Productivity: Sync Your Emails Directly from Litmus to Your ESP


Getting your email from your code editor into your ESP has always been a hassle. You had to copy your code and swap out image URLs, head to your ESP, create a new campaign there, and upload your email before you could send a test email or send your email to your subscribers. Whenever you spotted an error or made any change to your email, you had to copy and paste the code to your ESP again—a cumbersome, time-consuming, and error-prone process.

We decided that wasn’t good enough for Litmus Builder users.

With ESP Syncing in Litmus Builder, you can say goodbye to copy and pasting your code. Move your code from Builder to your ESP with a click of a button. Once connected, we automatically sync your email whenever you’re making changes to your code.


With ESP Syncing in Litmus Builder, you can automatically sync your email from Builder to your ESP in a single click.

Start by authenticating your ESP credentials and selecting where you’d like to sync in the the email in your ESP, such as Templates or Campaigns, and then we take care of the rest—no configuration required other than logging in. Builder will then compile the code for you, upload images to your ESP and swap out the image URLs, and upload the final HTML to your ESP.

Once your email is synced, any edit saved in Builder will also update within your ESP. Finally, Litmus Builder and your ESP are on the same page: no more switching back and forth between them when building your emails.

ESP Syncing also works with all Builder compilation features, such as CSS inlining, Partials, and Tracking Manager. It’s important to note that syncing is one-directional and only occurs from Builder to your ESP, not from your ESP to Builder.


If you’re on a Litmus Plus plan or above, you can start syncing your Builder emails with:

  • MailChimp
  • Campaign Monitor

If you’re on our Enterprise plan, you can also use:

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

We will be adding support for more ESPs soon.


You can access ESP Syncing from Builder. Simply click on the cloud icon in the top right of any Builder email to open the ESP Syncing modal.
