Our engineering team has rolled out a change to mitigate this behavior and allows for all emails to again reliably send from Pylon. We are still waiting for confirmation from our vendor that the underlying cause on their end has been fixed before calling this fully resolved. We will post an additional update here once that is confirmed. We appreciate your patience while we were working on a fix, please reach out to Pylon support with any questions.
