Trusted by Chicco, Metropolitan, Rozetka, and ecommerce and SaaS companies across Europe, with 24/7 support included on every plan and 6,000 free monthly emails during a four-month trial.
Why choose UniOne over Mailgun?
The decisive argument is data jurisdiction. Mailgun is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
UniOne removes that overhead. As a Cyprus-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.
