Kit
Kit, formerly known as ConvertKit, provides an email platform aimed at creators and other people building an audience. Its website presents tools for collecting subscribers, writing and sending newsletters, and organising email sequences. The service can help bring recurring communication into one workspace instead of maintaining separate manual mailing lists.
The official site explains its plans and additional facilities for creators. The functions and limits available to an account depend on the selected service, and email contacts must be handled in accordance with the applicable permissions and rules. Kit is operated by Kit, Inc., an Idaho corporation. It supplies software for managing audience relationships; using the platform does not itself provide an audience or guarantee income from newsletters or related offers.
