Retention.com: sovereignty score and 8 European alternatives

Retention.com is a US identity-data service that resolves anonymous website visitors to a person with a single tag and adds identifiers such as hashed emails and attributes, delivered through real-time APIs and flat files. Its group of brands includes RB2B, for visitor identification in B2B, and Retention FLEX, formerly Retention.com, which targets direct-to-consumer ecommerce teams.

The service is operated by GetEmails, LLC, doing business as Retention.com, with an address in Austin, Texas. According to its privacy policy, the service and website are hosted in the United States and data is generally stored there. The policy does not mention the GDPR or describe a process for EU data subjects, and no EU hosting option is described. The product is proprietary. For a European organisation, matching website visitors to individuals requires a lawful basis under the GDPR and the ePrivacy rules, and the provider is subject to US law. A legal review and a written data processing agreement are advisable before use.

Why digital sovereignty matters with Retention.com

Retention.com is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Retention.com hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Retention.com is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Retention.com together with your other vendors and gives a total score, a heatmap and the main risk drivers.
