Gilt Groupe Inc. is moving to become more intimate with its members, via a new service that personalizes the daily sales offered by the flash-sale e-retailer.

Gilt, No. 54 in the Internet Retailer Top 500 Guide, says the Your Personal Sale feature will offer “completely unique” daily sales to individual consumers who have signed up to receive Gilt’s daily sale notifications. Gilt crafts the sales based on an algorithm that takes into account such factors as past purchases and browsing, what brands the shoppers look at most and seasonality. Shoppers can provide feedback to Gilt to make the sales even more personal, the e-retailer says.

Consumers can spot their personalized sales via a badge, and shop the personalized offers on Gilt’s e-commerce site along with its mobile apps. Sales last for 24 hours.

“We always look for new ways to offer our members more of what they love, so we’re thrilled to launch personalized sales and offer millions of loyal customers a unique way to access the Gilt vault and shop their favorite brands and categories every day,” says Steve Jacobs, Gilt’s chief information officer “This is the next phase of the flash sale model—we’re leveraging that sense of curation and discovery that our members already know and love about Gilt, and tailoring that shopping experience just for them.”

Gilt did not say what technology it used for the service, but according to the Top 500, Gilt handles personalization in-house. Less than half, or 47%, of merchants in the latest edition of the research and ranking publication personalize web site content to cater to shoppers’ interests. A larger percentage, 76.4%, of Top 500 retailers offer product recommendations.
