Batch request limits
The number of items in the batch is not limited, but each request to the API is limited to 50 MB maximum, so please ensure your API request body remains within this limit.
Use individual email sends if want granular tracking
Due to the nature of email we can only track events such as sent, delivered, read and clicked down to the transactional email request, therefore if you want these events for each recipient then please only send to a single email address per transactional email request.
