Can I upload my list in Mandrill?

Lists can't be uploaded or stored in Mandrill. Recipient or subscriber lists should be managed in your own database or application. Then, when you're ready to send an email, recipient information is passed to Mandrill in your API request or SMTP message.

Note

If you're looking for a service that provides list-management services as well as the ability to create and track bulk emails, check out MailChimp.
