SignalHire

SignalHire is a professional contact-data service for recruiters, sales teams, and marketers who need verified email and phone details. It suits teams that want prospect discovery, enrichment, and outreach tools in one place. The broad workflow is appealing, but the free allowance is small and the same $69 monthly price buys different credit totals depending on contact type.

Overview

Search across professional profiles by name, title, company, and location, then enrich up to 1,000 profiles at a time. SignalHire gives a contact database size of 850 million; its database page describes more than 900 million profiles and more than 30 million companies. Direct-dial data and technographic filters can make the service useful for teams with varied sourcing needs, though the credit limits—not the headline database scale—set the practical volume a subscription can support.

SignalHire says it checks email addresses with third-party verification tools before showing them, a useful step for teams trying to avoid invalid addresses. Its data comes from public sources, licensed third-party providers, and user contributions. The company says it complies with GDPR and CCPA and provides access, correction, deletion, and opt-out rights.

Key features

Search, enrichment, and browser access

Filters cover name, title, company, and location, and batch enrichment handles up to 1,000 profiles. The browser extension can find contact details on social and professional sites, with downloads for Chrome, Firefox, Edge, and Opera. That makes SignalHire accessible during both list-building and individual profile research rather than confining discovery to its web interface.

Outreach and API

Email Sequences supports multi-step cold outreach with tracking, reply pauses, send windows, and analytics. It works with Outlook or Microsoft 365, or a company-domain mailbox. API access includes Person and Search endpoints; Company API access is available on request through support. Integrations include Salesforce, HubSpot, Zoho Recruit, Pipedrive, Recruitee, and Ashby, giving recruiting and sales teams routes to bring contact data into existing workflows.

Pricing

The free plan costs nothing and includes 5 credits, with no credit card required. Installing the extension adds 10 free credits each month. That is enough to sample the service, but not a substantial ongoing sourcing allowance.

Emails, Phones, and Emails & Phones each cost $69 a month, billed monthly, and each includes unlimited users and unlimited exports. Emails provides 1,000 credits for email-only use; Phones provides 435 credits for phone numbers; the combined plan provides 435 credits for emails and/or phone numbers. The email-only option stretches further for teams focused on addresses, while phone-focused and mixed use draw on the smaller 435-credit allowance. Unlimited seats avoid per-user charges, but do not expand the credit pool.

Scale has custom pricing and includes a bulk license, custom contact details, unlimited users, job-change tracking, and API access. It is the relevant tier for teams needing those capabilities beyond the listed monthly plans. The pricing note also gives a paid starting point of $57/mo (annual), distinct from the monthly plan prices.

Platforms

SignalHire runs on the web, through an API, and as a browser extension. The extension supports Chrome, Firefox, Edge, and Opera. That range suits teams mixing browser-based research with CRM or ATS workflows and API-connected processes.

Who it's for

Recruiters can use the profile filters, phone data, and ATS integrations for candidate sourcing; sales and marketing teams can use company and location filters, enrichment, and email sequences for prospecting. It is a stronger fit when contact discovery and outreach belong in the same workflow. Buyers seeking only occasional contact lookups should weigh the 5-credit free plan and paid credit allowances carefully.

Pros and cons

Pros: Search, bulk enrichment, verification, extension, sequences, and API access cover several stages of contact work.

Pros: Unlimited team members and exports on the three listed paid plans avoid seat and export-count charges.

Cons: The free plan's 5 credits are limited for regular use, even with the extension's monthly credits.

Cons: The $69 monthly plans offer materially different quotas: 1,000 email credits versus 435 phone or combined credits.

Cons: Scale pricing is custom, so teams needing its bulk license or job-change tracking must seek a quote.

Alternatives

For a different contact-finding service, consider GetEmail.io, which has a free plan with 10 monthly credits, CSV download, and API access. Voila Norbert, Findymail, Wiza, Anymail Finder, Clearout Email Finder, GetProspect, and Minelead are other alternatives to compare.

Verdict

SignalHire is best for recruiting, sales, and marketing teams that want contact search, enrichment, browser research, outreach, and API access under one roof, with no per-seat charge on its listed monthly plans. Its main trade-off is quota: the free tier is only a toe in the water, and phone or mixed use receives fewer credits than email-only use at the same monthly price. Choose it for workflow breadth; look elsewhere if your priority is a larger allowance for one contact type at a lower monthly cost.
