About

Mailfully is a hosted transactional email API for developers who need to send and receive messages from applications. Teams can send receipts, password resets, sign-in links, and alerts through a REST API or Node.js SDK, verify custom sending domains, and use reusable templates with variables. Per-message logs show delivery events, while webhooks can report deliveries, bounces, complaints, opens, and clicks to an application endpoint. Automatic suppression prevents later sends to addresses that bounce or complain. Mailfully also supports inbound email through a webhook and API, domain and message management from a command-line tool, delivery analytics, and an MCP server that lets compatible AI coding tools send messages and check their status. A test mode routes test messages to a simulator before live sending. The service is available through a free plan and paid monthly plans.

About

Unitpost is an end-to-end customer communications platform. You describe the workflow you want (a welcome series, shipping updates, a win-back campaign, etc.) and Unitpost builds it for you: ready to run across email, text, and WhatsApp. Today we support transactional + marketing email with a hybrid template system (visual + code), contacts, segments, campaigns and automations. The foundation is built horizontally from day one: one contact model, one event system, one pricing model (shared sending balance), and every action works the same way in the UI, via API, and through our agent (Ask Unit). We are not building another email tool. We are building the messaging layer that replaces the pile of tools teams currently stitch together and can be prompted for result, not manually built.
