Mailazy: sovereignty score and 8 European alternatives

Mailazy is an email tool for product teams at B2B and B2C SaaS companies. From a dashboard you build onboarding and drip flows on a visual canvas, send or schedule newsletters, and trigger emails from events in your own application with a single API call. It also provides contact lists, templates with version history, AI-generated drafts, logs of every send, and team roles with single sign-on. The service is delivered as SaaS; the emails themselves are sent through an SMTP provider that you connect yourself, such as SendGrid, Mailgun, Postmark or Amazon SES.

Mailazy's website does not state in which country the company is based or where its data is stored; for hosting details it refers customers to the vendor. Its privacy policy says data may be processed outside your own country. The software is not open source. Because sending runs through your own SMTP provider, the choice of that provider also shapes the jurisdiction of your email traffic. Ask Mailazy in writing about hosting and sub-processors before adopting it.

Why digital sovereignty matters with Mailazy

Mailazy 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.

Mailazy hosts data in EU, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

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