Unitpost

Unitpost is a unified email communication platform designed to handle both transactional and marketing emails from a single interface. It provides tools for building, sending, and tracking emails, aiming to streamline workflows that typically require separate solutions for different types of email communication. The platform is suitable for teams that want to manage their entire email process—ranging from password resets and alerts to newsletters and campaigns—using one system.

Key features of Unitpost include a hybrid email editor that combines a visual builder with the option to write code in constrained TSX using a React component library. The editor allows users to drag and drop sections, rows, buttons, and images, or switch to code mode for greater control, with both approaches producing the same output. A template gallery offers ready-to-send designs for transactional and marketing emails, which can be previewed, copied, or cloned into a workspace. The @unitpost/email component library is open-source, MIT-licensed, cross-client tested, and available on npm, enabling developers to build and preview emails without needing a Unitpost account.

For sending emails, Unitpost offers a REST API with features such as idempotency keys, batching, scheduling, and the ability to reference saved templates or pass HTML inline. The API is supported by SDKs for multiple programming languages, and it comes with an auto-generated OpenAPI specification. The platform can also send emails from AI agents, with support for integrations like ChatGPT, Claude, and Gemini, and provides webhooks with signed payloads and retries for event notifications.

Analytics and deliverability tools are built into the dashboard and API, tracking delivery, open, click, bounce, and complaint events for each message. Users can manage unlimited contacts, import and tag contact lists, build audience segments, and handle consent and suppression automatically, with support for both global and topic-level unsubscribes. Guided domain authentication with DKIM, SPF alignment, and DMARC is included to help ensure high deliverability rates. Pricing is based on usage, with unlimited contacts and a pay-for-what-you-send model, and users can start sending emails for free.
