Postmark Now Supports Multiple Recipients in Email Messages`, a new feature was added to Postmark, allowing customers to pass multiple addresses in the To field and optionally include Cc and Bcc fields with one or more additional recipients. The decision to implement this feature came after considering the limitations of not supporting such functionality due to concerns over implementation complexity, but ultimately decided it was necessary for customer convenience. The new feature also includes a solution to parse bounces that are received, allowing customers to review the full text of bounce reports and potentially identify the original recipient who triggered the bounce or spam complaint. The client libraries will need to be updated to support the new features, with changes expected in the Ruby gems soon.
