All private information, like account passwords, are encrypted—MailChimp’s staff can’t even view them. If you lose your password, it can’t be retrieved—you have to reset it. All login pages are 128‑bit secure, and account data is regularly mirrored and backed up offsite.
MailChimp uses a world‑class data center that manages our servers 24/7, has redundant power supplies, redundant cooling systems, and redundant networks. They employ card‑key and biometric security procedures, and guarantee 100‑percent network up‑time.
