Intuit Mailchimp takes data security and privacy very seriously, and we recognize that our security measures and practices are important to you. While we cannot expose too much detail around our practices (as it can empower the very people we are protecting ourselves against), we can provide general information to give you confidence in how we secure the data you entrust to us.
Data Center Security & Server Locations
- Mailchimp delivers billions of emails a month for millions of users. Mailchimp's owned and operated servers are located in world class data centers in the United States. In addition, we leverage third-party vendors who process personal data and provide services to Mailchimp. We may transfer data to those third parties as outlined in our Privacy Statement and Data Processing Addendum (DPA), and in accordance with data protection laws.
- Our data centers manage physical security 24/7 with biometric scanners and the usual high tech stuff that data centers always brag about.
- We have DDOS mitigation in place at all of our data centers.
- We have a documented "in case of nuclear attack on a data center" infrastructure continuity plan.
Protection from Data Loss, Corruption
- User accounts are segregated from each other through multiple layers of logic which prevent corruption and overlap
- MailChimp’s technology infrastructure includes network devices such as firewalls, and IDS/IPS tools which are strategically placed to control and monitor network traffic for data loss and corruption
- Account data is mirrored and regularly backed up off site.
Application Level Security
- Mailchimp account passwords are hashed. Our own staff can't even view them. If you lose your password, it can't be retrieved—it must be reset.
- All login pages (from our website and mobile website) pass data via TLS 1.2 or higher.
- The entire Mailchimp application is encrypted with TLS 1.2 or higher.
- Login pages and logins via the Mailchimp API have brute force protection.
- We provide the ability to enable email or SMS notifications about key activity.
- We provide the ability to enable two-factor (2FA) authentication to your Mailchimp account.
- We perform regular external and internal security penetration tests throughout the year using different vendors. The tests involve high-level server penetration tests, in-depth testing for vulnerabilities inside the application, and social engineering drills.
- We can confirm that any findings are addressed and repaired. The findings of our pen-testing results are kept strictly confidential and are not shared externally- even under NDA. We can confirm that any findings are addressed and repaired.

- Employees on teams that have access to customer data (such as tech support and our engineers) undergo criminal history and credit background checks prior to employment.
- All new hires and contingent workers are required to sign Non-Disclosure and Confidentiality Agreements. Additionally they are required to attend and certify completion of training on Intuit's Code of Conduct and information security policies including acceptable use.

Coverage includes, but is not exclusive to: coverage for cyber incidents, data privacy incidents (including regulatory expenses), general error and omission liability coverage, excess cyber liability coverage, property and business interruption coverage, as well as international commercial general liability coverage.
