Today, we are announcing MailVeri 2.0, our biggest platform upgrade yet. Over the past several months, our engineering team has rebuilt our core verification pipeline, redesigned the user dashboard from the ground up, and introduced native Model Context Protocol (MCP) support for AI coding agents.
Why MailVeri 2.0?
Email infrastructure in 2026 has become increasingly complex. Major mail providers like Google, Microsoft 365, and Yahoo have tightened spam filters, expanded aggressive greylisting, and increased catch-all domain configurations to protect user privacy.
Traditional verification tools often struggle here, returning high rates of inconclusive “Unknown” results or triggering false positives. MailVeri 2.0 addresses these modern deliverability challenges with a modernized verification stack.
1. Next-Gen Verification Engine: Deeper, Faster, Smarter
Our new verification engine represents a major overhaul of our handshake and deliverability intelligence systems:
- Deep SMTP Handshake Analysis: Performs multi-stage protocol checks that simulate genuine mail delivery without sending test messages, cutting through aggressive greylisting defenses.
- Drastic Unknown Reduction: Advanced heuristics and fallback routing significantly reduce “Unknown” results compared to legacy engines.
- Real-time Catch-All & Disposable Intelligence: Continuous intelligence updates identify newly registered disposable providers and catch-all behaviors instantly.
2. Redesigned Modern Dashboard
We completely overhauled the web app to give growth marketers, developers, and deliverability engineers faster access to the metrics that matter:
- Granular Status Breakdown: Clear, color-coded categorization across 7 industry-standard states (Valid, Invalid, Disposable, Role-based, Catch-all, Full Inbox, and Unknown).
- Instant Batch Cleanups: Drag-and-drop CSV uploads with live progress bars and instant background queues.
- Custom Result Exports: Export only 100% deliverable emails with a single click, or download full audit reports with technical bounce codes for your compliance records.
3. Native Model Context Protocol (MCP) Server
Developers and data teams are increasingly using AI assistants like Cursor, Claude Desktop, and custom agents to build automation workflows. MailVeri 2.0 now provides an official Model Context Protocol (MCP) integration, open-sourced on GitHub at github.com/mailveri/mailveri-mcp.
Connecting MailVeri to Claude Desktop or Cursor
Add the MailVeri MCP definition to your claude_desktop_config.json or .cursor/mcp.json:
1{2 "mcpServers": {3 "mailveri": {4 "command": "uvx",5 "args": [6 "--from",7 "git+https://github.com/mailveri/mailveri-mcp",8 "mailveri-mcp"9 ],10 "env": {11 "MAILVERI_API_KEY": "YOUR_MAILVERI_API_KEY"12 }13 }14 }15}Or Add via Claude Code CLI
If you use Claude Code in your terminal, add MailVeri with a single command:
claude mcp add --scope project --env MAILVERI_API_KEY=YOUR_MAILVERI_API_KEY mailveri -- uvx --from git+https://github.com/mailveri/mailveri-mcp mailveri-mcpOnce connected, you can prompt your AI directly:
“Verify all contacts in our waitlist CSV, remove disposable domains, and generate a clean list of valid enterprise prospects.”
