Security questions

Is Mailjet reliable, secure and confidential? Is our data safe?

Mailjet is ISO 27001 certified, the international standard for best practices in terms of information security. We are committed to following strong security measures to protect your data and applicable laws that protect your privacy.

Where is my personal data stored?

Your data are stored in our secure data centers located exclusively in the European Union, with Google Cloud Platform in London (United Kingdom), Frankfurt (Germany) and St. Ghislain (Belgium) and also with OVH in Roubaix (France).

Is our data backed up in case of an emergency?

The full data is hosted on highly secured servers. Data is backed up daily and written to multiple disks instantly. We can perform a full backup recovery in case of unforeseen event and system-wide emergency.

Are our emails lost in case of issues with Mailjet's servers?

Mailjet considers reliability as a first priority and the basis for high deliverability. We ensure that all emails are sent via queuing in case our servers encounter issues. Our hardware is also fully redundant so even if one disk or server fails nothing will be lost.
