From $9/10k credits Free trial MCP server API
Bottom line
Pay as you go bulk email verifier for recruiters and outbound teams cleaning candidate or lead lists before a send. Credits never expire, 10,000 checks cost $9 and 100,000 cost $59, and signup includes 1,000 free credits with no card. It also has a REST API and an official MCP server for AI assistants.
Stands out for: Price per check is among the lowest published in the category: $9 for 10,000 and $299 for 1,000,000, against $39 for 10,000 at MillionVerifier, with no subscription and credits that never expire. Only successful verifications use a credit, and an official MCP server lets Claude, Cursor or Codex verify single emails or whole batches from chat.
Watch out for: It is a young brand with no Capterra or G2 profile yet, and the accuracy figure on its site is the vendor's own claim, so test it on a list whose bounce rate you already know before cleaning a large one. Purchases are final with no refunds, and the MCP server runs on your own machine through uv rather than as a hosted endpoint, so setup needs a terminal.
Overview
MailVeri is a bulk and real time email verification service. You upload a CSV, Excel or text file of up to 1,000,000 rows and 100MB, it finds the email column itself, and returns each address marked valid, invalid, disposable, role account, catch all, full inbox or unknown. It never sends a message to the address being checked.
Checks cover syntax, domain and MX records, an SMTP mailbox handshake, catch all domains, disposable providers and role addresses such as info@ or support@. Results can be downloaded as a full archive or a filtered CSV, and webhooks report when a batch finishes.
A REST API handles single checks for signup forms, and ready made integrations cover n8n, Make, Zapier, Google Sheets, Clay, Apollo and GoHighLevel. The official MCP server, installed from GitHub with uv, gives AI assistants six tools to verify one email, submit and track batches, download results and check the credit balance.
Pricing is pay as you go only: $9 for 10,000 credits, $59 for 100,000, $299 for 1,000,000 and $999 for 5,000,000, with enterprise quotes above that. Credits never expire, every feature is on every pack, and new accounts get 1,000 free credits.

MCP server
Official MCP server from the vendor, published on GitHub as mailveri-mcp and installed with uv, so it runs on your own machine rather than as a hosted endpoint; an SSE mode allows a self hosted team server. Authenticate with a MailVeri API key. Six tools cover single email verification, batch submission, batch status, result download, batch deletion and credit balance, using the same credits as the web app.
