Comparison
tinysend vs Mailgun
Keep the workflow layer, send from your own Amazon SES account, and run the software on infrastructure you control.
Read the setup guide →What this open-source release covers
Your SES account
tinysend assumes a least-privilege IAM role and never stores long-lived AWS access keys.
The essential workflow
Transactional API, contacts, versioned templates, broadcasts, suppressions and optional tracking.
Agent-ready by design
Use the REST API, typed npm SDK, OpenAPI document, llms.txt and MCP server from the same installation.
