I want to use Salesforce to kick off triggered send e-mail via the ExactTarget REST API. How many e-mails can I send over in the JSON per API request? Also, is there a maximum number of transactional e-mails I can send per day, or a maximum number of API requests I can make in an hour/day/whatever time frame? Is using sendBatch an option/requirement here?
I'm accustomed to limitations on activities like this within Salesforce but haven't read much on any such limitations when working with ExactTarget.
