Go to SparkPost  Dashboard→



here is an example #SparkPost list input file … hopefully csv’s will upload here
→ #shucks , they get an “invalid media type” error.

okay here is the test template …
recipient@example.com,Example Recipient,reply@example.com,"{""foo"": ""bar""}","{""member"": ""Platinum"", ""region"": ""US""}","[""test"", ""example""]"
