How Leadsets and Wiza differ

Both products help you find work emails for B2B prospecting, and both expose their data to AI agents through a remote MCP server. The difference is where each one starts.

Leadsets is built as an API and MCP server first. An agent in Claude, ChatGPT, Cursor or your own code calls eight tools for people and company search, enrichment, email verification and company website scraping. There is no dashboard to work in: results come back as structured JSON with match reasons and a checked date on each field.

Wiza describes itself as a prospecting tool that finds and verifies work emails, personal emails and mobile phone numbers through a web app (Wiza Prospect), a Chrome extension for LinkedIn profiles and company websites, CSV and CRM import, an API and an MCP server. It suits reps who reveal contacts as they browse, as well as teams that integrate through its API.

Pricing and what you pay for

Leadsets charges a flat monthly fee with no credits: Solo $29, Pro $99, Team $399 and Max $999 a month (USD). Each plan has fair-use limits per rolling five hours and per week, for example 1,000 enrichments per five hours and 5,000 per week on Solo. Records only count when data comes back, and plans are per account, not per seat. Website scraping is an add-on from $9 for 1,000 units. The free plan is 1,000 records, one time, with no card. Full limits are on the pricing page.

Wiza prices per user. According to its pricing page:

Starter: $49 per user per month, monthly only, with 100 valid emails and 100 phone numbers per month and automatic overage at $0.15 per valid email and $0.35 per phone.
Email: $99 per user per month billed monthly with 500 valid emails, or $83 per user per month billed annually ($990 a year) with unlimited email reveals and 2,500 exports per month.
Email + Phone: $199 per user per month billed monthly with 500 emails and 500 phones, or $166 per user per month billed annually ($1,990 a year) with unlimited email and phone reveals.
Team: custom pricing, billed annually, 3+ users, with API access.
API credits: one-time purchase at $0.025 per credit, minimum 2,000 credits ($50), deducted only when data is returned.

Wiza says its plans charge only for valid emails, and risky emails are free. Its free plan is 20 valid emails and 5 phone numbers, one time. Wiza's help center notes that annual unlimited plans cap bulk exports at 2,500 per month and reveals at 500 per 24 hours. For more detail see Wiza pricing explained.

Data, verification and labels

Wiza says it has 850M+ contacts and 40+ data points, and claims 99%+ deliverability (97% for valid emails). It says it verifies at request time with syntax, domain, MX, SMTP, catch-all and disposable checks, and labels each result valid or risky. Wiza puts the deliverability of risky emails at 50 to 70%.

Leadsets does not publish a total record count. Its data comes from licensed suppliers and permitted public sources, every record is re-checked monthly, and each field carries its source, last-checked date and confidence. Emails go through a verification waterfall (syntax, DNS and MX, a mailbox-level check, then a second verifier for uncertain or catch-all results) and return one of four labels: verified, catch-all, unknown or invalid. Catch-all and unknown stay separate rather than sharing one risky bucket, which helps if you send to catch-all domains at lower volume. See how Leadsets verification works and what a catch-all email is.

Coverage differs in one clear way: Wiza returns mobile phone numbers, and Leadsets does not offer phone numbers yet. Leadsets returns work emails, roles, company data and US personal emails on paid plans.

API, MCP and agent workflows

Both have an official remote MCP server. Wiza's runs at mcp.wiza.co, accepts OAuth or an API key, and per Wiza offers tools to enrich contacts and companies, search prospects and companies and build lists in ChatGPT, Claude and Codex, using existing plan or API credits. Wiza's REST API has an OpenAPI spec and webhooks, with individual reveals limited to 15 requests per second. Its pricing page lists API access on the Team plan, though one-off API credits can be bought without it. Wiza does not publish language SDKs.

The Leadsets MCP server at https://mcp.leadsets.ai and its REST API are on every plan including Free, with TypeScript and Python SDKs, idempotency keys, cursor pagination and Retry-After headers. Beyond search and enrichment it includes scrape_jobs for hiring signals and scrape_company for structured homepage profiles, plus get_usage so an agent can check remaining limits before a run. Setup steps are in the MCP docs.

On integrations, Wiza lists Salesforce, HubSpot, Pipedrive, Zoho, Attio, Outreach, Salesloft, Gong Engage, Zapier, Clay and n8n, plus a Chrome extension. Wiza removed bulk export from LinkedIn, Sales Navigator and Recruiter search pages on August 19, 2026, so the extension now works on individual profiles. Leadsets connects to HubSpot, Salesforce, Pipedrive and Attio through skills and its API, and to n8n, Clay and Make over HTTP. It has no browser extension.

Example: 400 verified emails a month

Maya Chen runs RevOps at Northwind Analytics (northwind.co) and wants Claude to build about 400 verified prospect emails a month for one seller.

Leadsets: Solo at $29 a month covers this inside its limits (5,000 enrichments a week), with search, verification and the MCP server included. She would not get phone numbers.
Wiza: Starter at $49 per user includes 100 valid emails; the other 300 would bill as overage at $0.15 each, about $94 that month at Wiza's listed rates. The Email plan at $99 per user monthly includes 500 valid emails. Either way she would have access to phone numbers on Wiza (100 included on Starter, $0.35 each on Email).

If Northwind later adds a calling motion that needs mobile numbers, Wiza covers that today and Leadsets does not.

Questions and answers

Is Leadsets cheaper than Wiza?

It depends on seats and volume. Leadsets is a flat $29 to $999 a month per account with fair-use limits, while Wiza starts at $49 per user per month with 100 valid emails and overage at $0.15 per valid email. Teams with several users or high email volume will usually see the biggest difference, but Wiza includes phone numbers that Leadsets does not offer.

Does Leadsets have phone numbers like Wiza?

No. Leadsets returns work emails, roles, company data and US personal emails on paid plans, and will only add phone numbers once sourcing rights and costs are clear. Wiza offers mobile phone numbers, priced at $0.35 per phone on overage or included on its Email + Phone plans.

Do Leadsets and Wiza both have an MCP server?

Yes. Leadsets runs a remote MCP server at mcp.leadsets.ai with eight tools on every plan, including Free. Wiza runs an official remote MCP server at mcp.wiza.co that works with ChatGPT, Claude and Codex and uses existing plan or API credits.

Is Wiza or Leadsets SOC 2 compliant?

Wiza's trust center lists SOC 2 Type 2 documentation available on request, along with GDPR and CCPA documents. Leadsets is not SOC 2 certified yet: Type I readiness is underway with a target of Q3 2027, and it runs a GDPR-aligned program with a DPA.

How do Wiza and Leadsets label risky emails?

Wiza labels emails valid or risky, charges only for valid ones and says risky emails have 50 to 70% deliverability. Leadsets uses four labels, verified, catch-all, unknown and invalid, and never rounds uncertain results up to verified. Invalid emails are never served as contact emails.

Can I use Leadsets or Wiza with Clay and n8n?

Yes. Wiza lists Clay and n8n among its integrations. Leadsets is called from a Clay HTTP API column, an n8n HTTP node or a Make HTTP module, or through its TypeScript and Python SDKs.
