Sephora's email strategy was analyzed over a 22 day period where the user signed up for their VIP program, abandoned a cart, and made a purchase. They received a variety of personalized emails including welcome emails, a birthday gift email, order confirmations, and an abandoned cart follow up. While Sephora collects good customer data and sends visually appealing emails, some improvements could be made such as implementing a double opt-in for signups, using smart sending to avoid overwhelming subscribers, and keeping a consistent sender address across emails.
