Coresignal review (2026): pricing, credits, data APIs, verdict

What Coresignal is

Coresignal is a B2B data company that sells company, employee and job-posting records through APIs and as bulk datasets, drawn from public web sources it collects under the Ethical Web Data Collection Initiative and refreshes in real time. It claims 4.5 billion-plus records and ten years in the business, figures of its own, and now fronts the data with an Agentic Search API that turns a plain-language description into a list. For cold email it is a lead-data source for teams that build their own pipeline rather than a tool reps click through.

Coresignal pricing explained

Database API plans are priced by monthly credits, with yearly billing 10% off and all yearly credits delivered up front. A free trial gives 2,000 credits for 7 days. Mini costs $49 a month for 2,500 credits, Starter $199 for 12,000, Pro $499 for 35,000, Growth $1,000 for 150,000, Premium $1,500 for 1,000,000 ($0.0015 a credit), Scale $3,000 for 4,000,000 and Elite $5,000 for 10,000,000. A full multi-source employee or company record costs 20 credits (a Core record 10), a business email found through contact enrichment 10, a job posting 1, an agentic search 20 in fast mode or 100 in reasoning mode. Every plan includes the Agentic Search API, Elasticsearch DSL, webhooks and the Contact Enrichment API; search preview starts at Pro; rate limits climb from 5 requests a second to 100-plus on Elite; support moves from email to an account manager at Growth and Slack at Scale. Monthly credits reset each cycle with no rollover, except a 3-month rollover from Premium up. Datasets start at $1,000 a month on a yearly contract, delivered as JSON or CSV, with the final price set by contract length, locations and source tier.

The terms are plain: cancel at any time and keep the plan and credits to the end of the cycle; renewing or upgrading early resets the cycle; yearly plans are paid up front; the website terms name Delaware law, while data purchases follow a separate agreement.

Records, search and enrichment

Multi-source records merge several public sources into one company or employee profile with a timestamp of the last update. Elasticsearch DSL gives exact filtering for those who know the fields, and the Agentic Search API takes a prompt and returns a list, charged per search rather than per record. Webhooks push results into whatever comes next, the Contact Enrichment API adds contact details where available, and the company’s own channel shows n8n workflows that enrich HubSpot companies from Coresignal.

What that means for cold email

Do the arithmetic before choosing a plan: 20 credits a record means Mini buys 125 records a month and Starter 600, which is a trial rather than a campaign; Pro’s 35,000 credits buy 1,750 records, and the per-record price only becomes cheap from Growth up. The data is fresh and broad, but the emails still need verifying and the sending still needs warmed inboxes on separate domains, neither of which Coresignal provides.

Who Coresignal is for, and who should look elsewhere

Coresignal suits teams with an engineer who want fresh company, employee and job data through an API to build lists, enrich a CRM or feed an agent. It is a poor fit for reps who want a point-and-click list builder. Apollo and Clay wrap data in a workflow, and Evaboot and Skrapp pull contacts from LinkedIn at a few cents each. The lead data category compares them. Cognism is the enterprise data vendor with phone-verified mobiles and intent data, sold by quote with five seats included.

Using Coresignal with PureMail

Build the list from Coresignal’s API, enrich and verify the emails, push the result to your sequencer by webhook, and send from PureMail’s Google Workspace or Microsoft 365 inboxes on separate outreach domains, authenticated and ready to warm. Keep each inbox to a modest daily volume and size the Coresignal plan by records a month rather than by the headline credit count.
