Epsilon Informs AbeBooks of E-mail Database Breach We have been informed by Epsilon, a third-party vendor we use to send e-mails, that an unauthorized person outside their company accessed files that included e-mail addresses of some AbeBooks customers. Epsilon has advised us that the files that were accessed did not include any customer information other than email addresses. As a reminder, AbeBooks will never ask customers for personal or account information in an e-mail. Please exercise caution if you get any emails that ask for personal information or direct you to a site where you are asked to provide personal information.
