Counted 2026-08-25. Verification is the step between finding an address and sending to it, and skipping it is how a sending domain gets burned. It is also the cheapest step in the chain to automate properly, because the answer is a boolean and the cost of being wrong is asymmetric. ## The numbers, generated at build time | Measure | Count | Of what | |---|---|---| | Entries tagged verify-email-deliverable | 15 | of 293 directory entries | | Distinct products | 15 | the rest are cross listings | | Official MCP server | 11 | vendor built and maintained | | Community MCP server | 3 | built by somebody else | | No server found | 1 | on the date each entry was checked | | Free to start | 6 | no payment, no sales call | | Solo reachable | 14 | free or paid self serve | | Bench tested | 0 | somebody here actually ran it | ## The ones with an official MCP server - [Anymail Finder](../tools/anymail-finder.md) Official MCP · Free to start Takes a name plus a company, domain, or LinkedIn URL, verifies the resulting work email against the mail server in real time, and only charges when... - [Enrow](../tools/enrow.md) Official MCP · Free to start Finds and verifies work email addresses and direct phone numbers from a name plus company domain or a LinkedIn URL, charging only when it returns a... - [Hunter.io](../tools/hunter-io.md) Official MCP · Free to start An email-finding and verification tool - given a name, domain, or company, it locates likely professional email addresses (via domain... - [LeadMagic](../tools/leadmagic.md) Official MCP · Free to start A B2B contact/company data API and CLI that finds and validates work emails, mobile numbers, and social-to-email matches, plus... - [Prospeo](../tools/prospeo.md) Official MCP · Free to start A B2B contact database/lookup tool that finds verified work emails and mobile phone numbers for a given person or domain and returns basic... - [Allegrow](../tools/allegrow.md) Official MCP · Paid, self-serve B2B email verification and deliverability platform - resolves catch-all/secure-email-gateway addresses that legacy verifiers mark "unknown," sends... - [CUFinder](../tools/cufinder.md) Official MCP · Paid, self-serve A credit-based B2B data lookup service where you feed in a company name, domain, LinkedIn URL, or person and get back an enriched company or contact... - [Dropcontact](../tools/dropcontact.md) Official MCP · Paid, self-serve A France-based, GDPR-oriented contact enrichment and email-finding/verification service that takes a name plus company (name, domain, or LinkedIn... - [Snov.io](../tools/snov-io.md) Official MCP · Paid, self-serve A B2B prospecting and outreach platform - finds and verifies emails/contacts, enriches company and contact records, manages prospect lists and a... - [Versium REACH](../tools/versium-reach.md) Official MCP · Paid, self-serve An identity-graph append service that turns partial contact records into enriched B2B and B2C profiles, plus audience sizing and real-time email... - [Wiza](../tools/wiza.md) Official MCP · Paid, self-serve Pulls verified work emails and mobile numbers for people found on LinkedIn or Sales Navigator and exports them to CSV or a CRM. ## The ones with a free tier - [Anymail Finder](../tools/anymail-finder.md) Official MCP · Free to start Takes a name plus a company, domain, or LinkedIn URL, verifies the resulting work email against the mail server in real time, and only charges when... - [Enrow](../tools/enrow.md) Official MCP · Free to start Finds and verifies work email addresses and direct phone numbers from a name plus company domain or a LinkedIn URL, charging only when it returns a... - [Hunter.io](../tools/hunter-io.md) Official MCP · Free to start An email-finding and verification tool - given a name, domain, or company, it locates likely professional email addresses (via domain... - [LeadMagic](../tools/leadmagic.md) Official MCP · Free to start A B2B contact/company data API and CLI that finds and validates work emails, mobile numbers, and social-to-email matches, plus... - [Prospeo](../tools/prospeo.md) Official MCP · Free to start A B2B contact database/lookup tool that finds verified work emails and mobile phone numbers for a given person or domain and returns basic... - [Findymail](../tools/findymail.md) No MCP found · Free to start An email finder and verifier that locates a person's work email from a name+domain, domain-only search, or LinkedIn profile URL, verifies... ## What this list is not It is not a ranking and it is not a recommendation. A job tag means the vendor says the tool does this. Nobody here has run any of them: 0 tools in this directory are bench tested. Two tools on the same list can be wildly different in coverage, price and quality, and this directory does not claim to know which. ## Sources - [The GTM MCP Directory, verify an email is deliverable](../jobs/verify-email-deliverable.md) this site - [The GTM MCP Directory, methodology](../methodology.md) this site - [The GTM MCP Directory, the counted data](../data.md) this site Every number on this page is generated from directory.json at build time and carries the date it was baked: 2026-08-25.
