Resumen
158,600 email addresses of people who received mail through the service between October 9 and 29, 2026. No names, phones or message bodies. Per the company, this stems from unauthorised access to the Arara email-delivery platform (recorded separately); this figure is a subset of the vendor scope and must not be added to it.
