TL;DR
The ZoomInfo TalentOS integration for Greenhouse enriches ATS records with verified contact details, broadens the reachable talent pool beyond social networks, and enables automated multi-channel outreach that feeds back into Greenhouse. High-volume sourcers and technical recruiting teams benefit most, particularly when InMail reach is limited; recommended best practices include pilot testing, mapping fields, enforcing access controls, and tracking KPIs such as contact rate, response rate, and time-to-first-screen. When implemented with clear rules and measurement, teams can expect faster pipeline build, higher contactability, and reduced manual effort. To further accelerate screening and improve resume review accuracy, pair these sourcing gains with an AI resume screening tool like ZYTHR.
The ZoomInfo TalentOS integration for Greenhouse connects ZoomInfo’s enhanced candidate contact data and sourcing tools directly into your Greenhouse recruiting workflow. By enriching profiles, surfacing verified emails and mobile numbers, and enabling direct multi-channel outreach, the integration reduces sourcing friction and increases the pool of reachable candidates for open roles. This article explains how the integration works, which recruiting teams benefit most, practical implementation advice, measurable outcomes to expect, and recommended KPIs to track after deployment. It also provides tactical examples and troubleshooting tips to help recruiting teams get the most from combining ZoomInfo TalentOS with Greenhouse.
At a high level, the integration enriches candidate records and search results in Greenhouse with TalentOS data, allows recruiters to import contact details and verified information, and supports exporting enriched candidate lists into automated outreach workflows. When paired with the ReachOut Chrome extension and TalentOS Talentflows, recruiters can source beyond social profiles, capture verified contact information, and begin multi-touch outreach sequences that feed back into Greenhouse as activity and candidate progress.

ZoomInfo TalentOS data coverage — what the numbers mean for sourcing
| Metric | What it means for recruiters |
|---|---|
| 130M+ enhanced contacts | Broad base of candidate profiles beyond public social footprints; useful for hard-to-find or passive talent. |
| 1.6B+ records (platform-wide) | Large-scale coverage to support volume sourcing and enterprise hiring programs. |
| 100M+ verified email addresses | High likelihood of reaching candidates via email—the most-preferred contact channel for 90% of talent. |
| 33M+ mobile phone numbers | Enables voice and SMS outreach where appropriate for faster engagement cycles. |
Who needs this integration? Teams that will see the most value are high-volume sourcers, technical recruiting teams filling niche roles, and centralized talent acquisition teams running pipelining or proactive sourcing programs. It’s particularly useful when public social outreach is limited by low InMail open rates, when hiring velocity matters, or when recruiters want to automate multi-touch outreach while keeping Greenhouse as the single source of truth.
Tactical sourcing workflows unlocked by the integration
- Overlay TalentOS on LinkedIn Use the ReachOut Chrome extension to reveal contact details for LinkedIn profiles and quickly create enriched candidate records in Greenhouse.
- Bulk enrichment Upload a CSV of prospects into TalentOS, enrich contact fields, and import back to Greenhouse with verified emails and phone numbers.
- Talentflow-triggered outreach Set automated sequences that combine InMail, email, and phone touches; track responses in Greenhouse for accurate pipeline attribution.
- Boolean search augmentation Combine TalentOS filters with Greenhouse job mappings to identify candidates who match hard-skills and pass initial screener criteria automatically.
How the integration typically works in practice: a sourcer finds a candidate on LinkedIn, uses ReachOut to surface contact details, clicks a single action to push that enriched profile into Greenhouse, and launches a Talentflow that schedules automated outreach. Activity logs and responses sync back, so hiring teams see outreach history and can move candidates through stages without manual record-keeping.
Common questions recruiters ask about the integration
Q: Does TalentOS data sync both ways with Greenhouse?
A: Most workflows enrich Greenhouse records with TalentOS data and send activity back to Greenhouse. Bidirectional field mapping depends on your integration settings and admin configuration.
Q: Will using TalentOS replace an ATS?
A: No. TalentOS supplements the ATS by expanding sourcing and outreach capabilities. Greenhouse remains the system of record for candidate stages and interview workflows.
Q: How fresh is the data?
A: ZoomInfo maintains continuous refresh cycles across its dataset; frequency can vary by record type. Validate freshness by sampling records in your target hiring markets.
Measurable outcomes to expect (typical impact ranges)
| Benefit | Typical impact or metric to track |
|---|---|
| Higher reachable candidate rate | Access to verified emails and phones often improves initial contact rates; expect measurable uplift versus InMail-only outreach. |
| Improved response rate | Combining multi-channel sequences with additional contact details can raise response rates—improvements depend on messaging and cadence. |
| Reduced time spent on manual research | Auto-enrichment cuts down manual profile research, freeing sourcers to focus on outreach and candidate evaluation. |
| Faster pipeline build | Automated Talentflows accelerate moving sourced candidates into active screening, reducing time-to-first-screen. |
Implementation considerations and best practices: map the fields you want enriched into Greenhouse before you enable sync, define a clear naming convention for source attribution, set up permissions so only authorized users can export contact details, and test a small pilot to validate enrichment accuracy and outreach cadence. Also align legal and privacy teams on acceptable use policies for contact outreach in target jurisdictions.
KPIs to monitor after enabling TalentOS in Greenhouse
- Time-to-first-screen Measures how fast sourced candidates convert to initial interviews after enrichment and outreach.
- Contact rate (delivered messages) Tracks the percentage of candidates with at least one verified contact method.
- Response rate Percent of candidates who reply to outreach sequences—useful for optimizing messaging and cadence.
- Pipeline conversion Ratio of sourced candidates who progress from outreach to interview and offer; helps measure quality of sourced pool.
- Time saved per requisition Estimate reduction in hours spent on manual sourcing and enrichment multiplied across open roles.
Troubleshooting & quick tips
Q: What if enrichment returns duplicate or conflicting contact data?
A: Establish a deduplication routine: prioritize verified fields, use timestamps to choose the freshest record, and set rules in Greenhouse to merge or flag duplicates for review.
Q: How to prevent outreach from appearing spammy?
A: Use multichannel sequences with personalized messaging, limit cadence frequency, and include clear opt-out options. Track open/reply metrics to refine messaging.
Q: How can I test reachability quickly?
A: Run a small pilot of 50–100 targets across roles, measure contact and response rates, and adjust Talentflow touchpoints before scaling.
Sample use case: a mid-sized SaaS company needs three senior backend engineers quickly. Recruiters run a TalentOS search for engineers with specific language and cloud experience, overlay contact data via ReachOut on LinkedIn profiles, bulk-enrich 200 candidates, and push them into Greenhouse. An automated Talentflow combines email, phone, and one InMail touch across eight planned touchpoints. Within two weeks, the team doubles their interview slate and reduces time-to-first-screen by 40% compared with their prior InMail-only strategy.
Security and compliance checks to perform before rolling out
- Access controls Limit who can export sensitive contact details and enforce role-based permissions in both ZoomInfo and Greenhouse.
- Data retention & opt-out handling Confirm how TalentOS handles candidate opt-outs and ensure your outreach sequences respect those preferences.
- Field-level audit logs Enable logs for enrichment and sync events so you can trace when and where candidate data changed.
