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

Mailjet's security standards are actually very high. Strong measures protect customer data from unauthorized access. We are committed to following applicable laws that protect your privacy.

You are the owner of the data associated with your account including transactions and customer records. We only provide service and maintain the integrity of your data. We run automatic encrypted backups to ensure your online data will always be safe and sound.

We systematically use a secure protocol for data transfers. Our team is also constantly checking for any possible security flaws and our servers’ integrity is closely monitored. However, nobody can consider being completely safe from hackers. To be clear, nothing is 100% secure and anyone who guarantees 100% security is making a promise they cannot even keep. The worst case scenario must always be considered. What we can promise is that we take all reasonable precautions to keep your data safe. Therefore, if a security breach occurs, Mailjet commits to notify you immediately. Mailjet will also take all the necessary measures to end the intrusion. If you have any questions about security on our Website, you should contact us at
