What it does
AI agents need email, but most teams hack SMTP relays and parse raw MIME. Threads break, replies disappear. mailbot gives your agent a real email identity: programmable inboxes, threaded send and receive, webhooks for every delivery event. One API. Built in: MCP Server (npx mailbot-mcp, works with Claude Desktop, Claude Code, Cursor), Node.js and Python SDKs, SPF/DKIM/DMARC deliverability. Free sandbox. No credit card.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
