Email personalization is an email marketing process that uses personal information of subscribers to produce more targeted emails.
Personalized emails are great because they provide subscribers and users with more relevant information, that interests them specifically, instead of the generic, “mass-produced” email content, that attempts to accommodate to all customer types.

The recommendation engine analyzes the unique browsing and buying behavior of every visitor to your store and then builds a unit of recommendations for each visitor, based on individual ranked visitor interests and demographics, as well as crowd wisdom extracted from other traffic on your shop.

A/B testing is a great tool to help improve your email marketing performance. A/B  testing is the only way to statistically prove which email campaign brings you the most success. It’s also the fastest way to figure out what your audience likes (and optimize your email campaigns accordingly).
