Shipping with AI takes a weekend. Getting customers is the bottleneck.
When anyone can build software with AI, distribution and unit economics decide who wins. Verify scraped outbound lists from $0.0002/email (up to 90% cheaper than legacy tools), keep cold email bounce rates strictly under 2%, and stop disposable signups from draining your AI API tokens.
Solve the distribution bottleneck on both fronts
Whether you are running high-volume cold outreach to land your first 100 paying customers or protecting your free trial from token farmers, MailVeri keeps your growth engine profitable.
Outbound Scale Without the Legacy Tax
Scraping 100,000 prospects from Apollo or Clay is effortless, but paying $649 on legacy verifiers kills bootstrapped unit economics. Clean 100K leads for just $59 (down to $0.0002/email at scale) with non-expiring credits.
Keep Bounce Rates Strictly Under 2%
Google Workspace and Microsoft 365 burn outbound domains the moment hard bounces cross 2%. Catch invalid, catch-all, full-inbox, and role accounts with 99%+ precision before launching on Instantly or Smartlead.
Stop Free-Trial AI Token Drain
AI apps are prime targets for free-trial abuse. Block 100,000+ disposable and burner email providers at signup before fake users exhaust your OpenAI, Anthropic, or GPU compute budget.
Native MCP for Agentic GTM
Built for modern builders using Claude Code, Cursor, Windsurf, Clay, and n8n. Let your autonomous sales agents verify prospect emails in real time before drafting or sending outreach.
Don't let verification fees cost more than building your product
AI scrapers and lead databases make it easy to export 100,000+ B2B prospects a month. Legacy verifiers punish you with steep markups and expiring credits; MailVeri is priced for lean founders and high-volume GTM teams.

Drop-in protection for signups & AI agents
Block burner emails at registration with a single REST call, or expose full list verification tools directly to Claude, Cursor, and Windsurf via Model Context Protocol.
1. Block Disposable Signups Before Granting AI Credits
Verify user emails at registration. Reject DISPOSABLE and INVALID addresses before issuing free LLM or GPU credits.
// Next.js / Node.js Signup Route: Protect Free-Trial AI Credits

}2. Automate Outbound Hygiene via MCP Server
Add mailveri-mcp to your agent configuration so Claude or Cursor can verify single leads and clean 1M-row batches autonomously.

}Frequently asked questions for AI founders
Why is email verification critical when scaling an AI startup or micro-SaaS?
AI coding tools have reduced software development time from months to days, shifting the primary startup bottleneck to distribution and unit economics. On the outbound side, unverified scraped leads cause hard bounce rates above 2%, permanently burning your cold email domains. On the inbound side, users registering with disposable burner emails drain expensive LLM API and GPU trial credits without ever converting.
How much does it cost to verify 100,000 scraped leads for cold outreach?
Verifying 100,000 emails on MailVeri costs $59 ($0.00059 per email), compared to $649 on ZeroBounce and $400 on NeverBounce—saving you up to 91%. High-volume packages scale down to $0.0002 per email ($999 for 5,000,000 credits), and credits never expire.
How does MailVeri prevent disposable emails from draining OpenAI or Anthropic trial credits?
By calling the MailVeri Real-Time Verification API during user registration, your backend inspects the email against a continuously updated database of 100,000+ disposable and temporary mail providers alongside live MX and SMTP checks. If the API returns DISPOSABLE or INVALID, you can block the signup before provisioning free AI tokens.
Can my AI agents verify emails autonomously inside Claude, Cursor, or n8n?
Yes. MailVeri provides an official Model Context Protocol server (mailveri-mcp) and REST webhooks. AI agents in Claude Desktop, Claude Code, Cursor, Windsurf, Clay, and n8n can verify individual prospect addresses, launch bulk CSV cleaning batches, and download deliverable lists autonomously.
