When you leave out send_at, attachments, content, or reply_to, the mailer errors out with 

{:error,
 [%{"field" => "attachments",
    "help" => "http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.attachments",
    "message" => "Invalid type. Expected: array, given: null."},
  %{"field" => "content",
    "help" => "http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.content",
    "message" => "Invalid type. Expected: array, given: null."},
  %{"field" => "send_at",
    "help" => "http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.send_at",
    "message" => "Invalid type. Expected: integer, given: null."},
  %{"field" => "reply_to",
    "help" => "http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.reply_to",
    "message" => "Invalid type. Expected: object, given: null."}]}

Just kidding. It turns out custom args can't have an integer. The library should automatically convert all integers in the Email struct to strings to prevent this from happening.
