The Postmark team has announced the addition of two new API endpoints, Server API and Sender Signatures API, to further automate their service. The Server API allows users to manage servers completely free of the website front-end, while the Sender Signatures API enables DKIM and SPF administration. To access these APIs, users must use an Account Token, which can be found in the Postmark settings. These new features aim to make automating the Postmark experience even easier for developers.
