Why Groundmail

• Our own mail servers and IP space. Your password resets and receipts don't share a pool with bulk marketing senders.
• Transactional email only. No newsletters or cold outreach on the platform, which keeps the sending reputation clean.
• Start free. Free covers 3,000 emails a month. After that, pay as you go is $15 a month with 20,000 emails included, then from $0.70 per 1,000, less as you grow. Pricing
• Built for code and for agents. REST API, SMTP, SDKs for Node, Python, Go, PHP and Ruby, a CLI, and an MCP server for Claude, ChatGPT and Cursor.
