If I use sendBatch to send multiple emails, is there a maximum number of emails limitation in the array? Thanks.

I don't think the Java API enforces any limitations on its own but you need to be coherent with the overall ExactTarget API guidelines which clearly state

  • Keep your triggered send batches of Subscriber objects to numbers smaller than 100 for asynchronous calls and less than 50 for synchronous calls.
  • Keep your maximum payload per call at less than 5MB.
  • Pass less than 10 attributes to avoid decreased performances.

More information available here.

  • Thanks for the information. I saw this in the soap api. So it is the same limitation for rest api? – Lin Sep 9 '14 at 5:17
