Motorical is a transactional email API and SMTP relay built around Motor Blocks — an isolated sending stream per project, with its own auth method, domain, rate limits, and delivery logs. Plans start at €2.49/mo with a 30-day free trial for new customers, plus a card-free developer sandbox for testing before you own a domain. Also includes encrypted IMAP mailboxes, an MCP server and CLI for AI coding assistants, and EU-based hosting.
Key Features:
Core Engine: Motor Blocks: The heart of the system. Create individual, isolated SMTP connection blocks for each of your applications. Granularly split and assign SMTP configurations with dedicated security settings, certificates, and authentication mechanisms for every specific need.
Interactive API Playground: Test features, debug integrations, and explore the API in real-time directly from the dashboard—no code required to get started.
MCP tools for transactional HTTP send and delivery inspection on Motorical. The server lets AI agents call Motorical APIs (not only read docs). It runs locally over stdio (Cursor, Claude Desktop, and other MCP clients).
"Your Own" Integration: Deeply integrate transactional email functions into your own stack. Motorical is built to be the engine room of your application's communications.
Real-Time Connectivity: Full support for real-time API access and webhooks, giving you immediate feedback on delivery, bounces, and engagement.
Communications Module: A simple but functional built-in module for managing mailing lists and running email campaigns without needing a separate marketing platform.
Encrypted IMAP: Not just for sending Motorical provides fully encrypted IMAP mailboxes for receiving and storing emails securely.
EU Sovereignty: All data is hosted and processed within the EU, ensuring strict GDPR compliance.
Motorical is the engine for developers, system administrators, and privacy-conscious businesses who need a reliable and self tailored smtp alternative that puts them in control.
