Constant Contact: sovereignty score and 8 European alternatives

Constant Contact is an online marketing platform built around email marketing. Users send email campaigns and newsletters, build automations, add SMS messages, and promote events and social media from a single environment. The platform targets small organisations and is delivered as SaaS through the browser. As a processor, Constant Contact handles your customers' contact data on your instructions as controller.

Constant Contact, Inc. is headquartered in Waltham, Massachusetts. According to Wikipedia, it has been a standalone company since 2021, owned by the US investors Clearlake Capital and Siris Capital Group. It falls under US jurisdiction, including the CLOUD Act. The documentation consulted does not state where data is stored; for transfers outside the EEA, the data processing addendum includes the EU standard contractual clauses and the UK addendum, and the company does not rely on Privacy Shield. The software is proprietary and not open source. European organisations therefore need to assess for themselves whether their mailing lists comply with the GDPR.

Why digital sovereignty matters with Constant Contact

Constant Contact 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.

Constant Contact 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.

Constant Contact 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 Constant Contact together with your other vendors and gives a total score, a heatmap and the main risk drivers.
