Mailjet vs Mailgun — FAQ
Is Mailgun GDPR compliant?
Mailgun may offer GDPR compliance features and EU data residency options, but as a US-headquartered company, it remains subject to the US CLOUD Act and FISA Section 702. These laws can compel US companies to hand over data regardless of where it is stored. The EU-US Data Privacy Framework provides some safeguards, but its predecessors (Safe Harbor and Privacy Shield) were both invalidated by the European Court of Justice. Mailjet, as a European company, is not subject to these US laws at all.
How does Mailjet compare to Mailgun in features?
Mailjet offers Transactional email API, SMTP relay, Drag-and-drop email editor, Real-time collaboration on templates, and 5 more features. While Mailgun's ecosystem may be larger due to its market position, Mailjet covers the core functionality that most teams need. The trade-off is typically between breadth of integrations (Mailgun) and data sovereignty with regulatory certainty (Mailjet).
Can I migrate from Mailgun to Mailjet?
Yes. Most European software providers, including Mailjet, offer migration tools or documentation to help you transition from US-based services. Under GDPR Article 20, you have the right to data portability — meaning Mailgun must provide your data in a machine-readable format. The migration process varies in complexity depending on your data volume and integrations, but for most teams it can be completed within a few days to a few weeks.
