Flat-price email verification for AI SDRs and agents*
Most verifiers charge a credit for every check, so an agent that loops and re-checks runs up the bill. On Pro list checks are a flat $39 a month with no credits, and agents get an MCP server and a clear send or hold answer on every result.
*Pro: the first 100,000 checks a month at full speed, then slower, never cut off. API and MCP calls are metered: 10,000 included, then $1.50 per 1,000.
What is flat and what is metered
- List checks (a CSV upload) have no credits and no per-email fee on Pro.
- API and MCP calls count against the 10,000 included each month, then $1.50 per 1,000 calls.
- Phone lookups and the email finder are not unlimited.

What agents get
- MCP server at simpleverifier.com/api/mcp with 7 tools: verify_email, verify_emails, get_job_results, clear_list, check_phone_format, check_domain, get_usage.
- verify_emails checks up to 100 addresses in one call.
- Every result carries action (send, send_with_care, retry_later or do_not_send), risk, likely_invented and reason_code. None is ever null.
- The REST API and list downloads add send_advice: safe, care, retry or do_not_send.
- 120 requests a minute per API key, shared by the REST API and MCP.
- Sign in with OAuth for ChatGPT and claude.ai, or send an API key from Claude Code, Cursor and VS Code.
Setup for Claude, ChatGPT, Cursor and VS Code is on the MCP docs page. To clear a lead CSV from Claude Code, Codex or Cursor, use the free list clearance skill.
Connect your agent
Create an API key, or sign in with OAuth from ChatGPT or claude.ai. Pro is $39 a month.
Common questions
- Is email verification for AI agents really unlimited?
- For list uploads on Pro, yes: the first 100,000 checks a month run at full speed, then slower, never cut off. Agent traffic uses the API or MCP, and those calls are metered: Pro includes 10,000 calls a month, then $1.50 per 1,000.
- Why does credit pricing matter for agents?
- An agent can loop and re-check the same lead. When each check spends a credit, the bill follows the loop. A flat plan does not charge per list check. Single calls through the API or MCP still count toward the included calls.
- What should an agent do with a result?
- Branch on action. Only send means the mailbox was confirmed. send_with_care and retry_later are not a yes, and do_not_send should go on a suppression list.
- How do I connect an agent?
- Create an API key, then add the MCP server to your client or call the REST API. The MCP docs page has the setup command for Claude, ChatGPT, Cursor and VS Code.
- Where do these competitor prices come from?
- Each row links the vendor's own pricing page and shows the date we read it. Prices change, so check the vendor before you buy. A vendor without a sourced figure is listed without a price.
