Are Email tools from EU companies GDPR-compliant?
EU-headquartered Email providers are subject to the GDPR by default and cannot be compelled to hand over your data under the US CLOUD Act. The Email startups on this page are based from Germany, Switzerland, and Austria, all within EU jurisdiction, which makes them a safer default for European businesses handling personal data.
How do I switch to a GDPR-compliant Email alternative?
Start by identifying which EU-based Email tools match your feature requirements from the list above. Most EU providers offer free trials and data migration guides to help you move from US-based incumbents. For a Email switch specifically, check what data export formats your current tool supports and whether the EU alternative offers an importer.
