Connect your ESP

Connect your ESP to Litmus in your account settings. Each ESP connection is custom built to the service provider's specifications so there may be some special steps depending on which you choose. You can connect multiple ESPs to your Litmus account, even more than one of the same service. Once you complete the sync setup for each of them, you'll be able to select the version you need for any of your emails.

  4. Find your email in the list of your most recent drafts or you can use the search box to find it. Then use the Start your spam test button in the lower right corner.
  5. Your test results will automatically begin to start populating. Litmus uses your ESP to send your email to 25+ spam services to assess issues that may lower your deliverability rates.
