A practical workflow for finding, verifying and reaching candidates with business contact data

TL;DR

ReachStream for recruitment agencies is a business contact database for finding clients and candidates.
Passive candidates rarely use job boards, so filters and direct outreach matter.
Filter by title, seniority, industry, location and company size, then verify emails.
Use direct dials with care and follow local calling and privacy rules.
Export to your ATS by CSV, Salesforce or HubSpot sync, or the Reach API.
Track response rate, bounce rate, sourcing productivity and source of hire.
ReachStream offers 500M+ contacts, 50M+ companies and 100M+ direct dials, plus 100 free export credits a month.

Why Use ReachStream for Recruitment Agencies?

ReachStream for recruitment agencies is a way to build and reach candidate and client lists from a business contact database instead of relying only on job boards. In this guide we walk through how an agency can use ReachStream to source more candidates: define the role, filter contacts, companies, verify emails, direct dials, push clean records into the ATS and track what works.

The Free plan includes 100 export credits a month with no credit card, so a team can test it on a live search. A quick note on the title: The workflow below is a practical walkthrough of ReachStream candidate sourcing, not a claim about one firm’s results. ReachStream is a business contact and company database, not a resume database.

How Does Sourcing Break Down for Most Agencies?

Most agencies hit the same wall. Job boards bring in active applicants, but the strongest people for senior and specialist roles are usually employed and quiet. Recruiters then spend hours switching between a professional network, a spreadsheet and the ATS, copying names by hand and guessing at emails. Recruitment agency sourcing tools help most when they cut that manual work and keep one clean list.

A recruitment agency database is that list: titles, employers, locations and verified contact details in one searchable place. Our guide to B2B data for recruitment agencies covers the basics, and our guide to recruitment data sources compares the options. ReachStream for recruitment agencies fits in as the contact layer next to your ATS and job boards, not as a replacement for them.

How Do Agencies Reach Passive Candidates?

Passive candidates are skilled people who are employed and not applying. They rarely appear on job boards, so agencies need a passive candidate database of their own: a searchable list of professionals matched to the roles you fill most. You build it from filters such as job title targeting, seniority, industry filters and location filters, then save the matches as a list you can return to when a new mandate arrives.

The first message matters. Keep it short, name the role and the reason you chose that person, and make it easy to say no. Because ReachStream records are refreshed on a 45-day cycle, a list you saved last quarter can be re-checked rather than rebuilt from scratch.

Which Filters Build the Best Candidate Lists?

ReachStream filters by industry, job title, seniority, location, company size and technologies used. For a recruiter, job title targeting finds the people who hold the role you want to fill, or the manager who is hiring for it. Seniority narrows the list to the right level, industry filters keep you inside the sectors you know and location filters keep it inside the geography of the job.

Company size helps when a role only makes sense at a start-up or at an enterprise. Technology Insights adds filters based on 22K technologies a company uses, which helps when you recruit for engineering or data roles and want employers with a specific stack.

AI Search lets you describe the people you want in everyday language, and Similar Companies expands from employers that already fit. Skills matching is the one step to handle outside ReachStream: it does not hold resumes or detailed skills, so use your ATS and professional networks for that.

How Do You Verify Contacts Before Outreach?

Recruiter contact data is only useful if it reaches a real person. Before any campaign, run every address through an email verifier, watch the bounce rate and remove anything that fails. ReachStream includes a built-in email verifier and verified candidate emails protect sender reputation and your response rates. For phone numbers, record where the number came from, and learn wrong-number outcomes.

Data enrichment fills missing titles, employers and contact fields on records you already hold and updates them as people change jobs. Our guide to B2B data accuracy explains how to test a sample before you commit to any vendor.

Can Agencies Use Direct Dials Responsibly?

Direct dials can get an agency to a hiring manager or a busy specialist faster than a switchboard. ReachStream offers 100M+ direct dials, and they are most useful for senior searches and for candidates who ignore email. Use business lines, call in working hours, say who you are and why you are calling in your first sentence and accept a no politely.

Rules differ by country and call type. Many regions apply do-not-call registers, consent rules for mobile numbers and data protection laws such as GDPR, so keep your own do-not-contact list and ask your legal team to review your process. Our guide on how to get a direct dial covers the basics.

Which Tool Handles Which Sourcing Task?

Candidate sourcing software comes in several types, and most agencies combine them. The table below compares three common ones. Adjust the rows to your own stack.

Tool	Best for	Typical fields	Watch-outs	What to test
Contact database	Reaching hiring managers and professionals directly	Title, employer, verified email, direct dial	Coverage varies by role and region	Share of target roles found
ATS and recruitment CRM	Tracking people through your pipeline	Applications, notes, stages, history	Records go stale without refreshes	Share of records updated this quarter
Professional networks	Skills, work history and warm introductions	Profiles, skills, connections	Platform limits on outreach and data use	Reply rate by message type

What Does a Scalable Sourcing Workflow Look Like?

Define the role: Write down the title, seniority, industry, location and must-have skills.
Build the list: Filter in ReachStream and save it as a dynamic list, the base of your candidate sourcing automation.
Verify and enrich: Run the built-in email verifier and fill missing fields.
Reach out: Send a short, relevant message and follow up by phone where appropriate.
Sync: Export to CSV or sync to Salesforce or HubSpot, then log every touch in the ATS.
Review: Check response rates each week and refresh your lists.

How Do You Connect Contact Data to Your ATS?

Your ATS stays the system of record. ReachStream does not have a native ATS integration, but it does offer CSV export, native Salesforce and HubSpot sync and the Reach API, so most agencies use a bulk export and import the list into the ATS or recruitment CRM, then log every touch there.

Recruiting workflow automation can handle the repeatable parts, such as importing a saved list, tagging the source and scheduling follow-up reminders, while recruiters keep the conversations.

Store only the fields you need, record the source and date of every contact and log the legal basis for contacting each person where the law requires it. Set a retention period and honor requests to access, correct or delete personal data under laws such as GDPR and CCPA.

How Should an Agency Measure Sourcing Efficiency?

Response rate: The share of messages that get a reply.
Bounce rate: The share of emails that fail, which shows data quality.
Pipeline by stage: The number of qualified people at each step.
Sourcing productivity: Qualified conversations per recruiter hour.
Time to fill: How long a role stays open.
Source of hire: Which channel produced each placement.
