We take the protection of our users' data seriously and have established multiple levels of testing to ensure the integrity of our system, which includes the following.
- Penetration tests on an ongoing basis to find any vulnerabilities within our application
- Extensive background checks for all MailChimp employees
- Continuous education to staff to inform them of new risks
Security and Our Databases
MailChimp supports SSL encryption throughout the application. SSL is a security protocol that allows your information to be transmitted securely.
All large account databases are kept separate and dedicated to prevent corruption and overlap. Smaller and free user accounts are placed into the same large database. As accounts grow in list size, they are migrated into their own database.
All passwords stored in our databases are salted and hashed using an industry standard hash function. We do not store any credit card information on our servers.
MailChimp will not sell or rent your subscriber lists.
We collect and process data about our users and their subscribers to help us improve features and learn more about the email industry in general. You can change your participation in this research at any time.
