Email client recommendations in Litmus

Email previews help ensure your email looks great in all the environments you select. Email client recommendations add data-driven suggestions to help you get more out of your email testing. 

NOTE: Email client recommendations are available in Plus and Enterprise plans.

Types of Recommendations


For Enterprise customers, these include email clients most frequently used by your subscribers based on Email Analytics data available from previous email campaigns and unique to your account.  These personalized recommendations help you test the clients most relevant to your subscribers so you can ensure a great email experience.

If enough data exists from prior campaigns, you will automatically see these recommendations. To generate additional data or ensure you are always getting the most up-to-date recommendations, be sure to add Email Analytics tracking codes to every campaign.


Clients based on overall popularity from all Litmus customers and their engagement data in aggregate.  Think of these as recommendations based on the data that drives our Email Client Market Share report.


Clients that have recently been added to our supported list for Previews or that you may not have considered yet for testing.  Since we update existing clients and add new ones regularly, you will see in this section so you are always testing in the latest environments.

NOTE: For Enterprise customers with Global Email Clients selected, any that are hidden will not appear in recommendations.

If you are already testing all of the clients your subscribers are using, that are most popular based on aggregated Litmus data, or that have been newly added, you will not see any Recommended clients. In this case, congratulations! You are already testing where it matters most.
