How to evaluate provider contact data vendors

Ben Argeband, Founder & CEO of Heartbeat.ai — Helpful and calm: “how to not get burned again.”

Who this is for

If you lead recruiting and you’re buying contact data to move clinicians from “sourced” to “submitted,” this is for you. Specifically: recruiting leaders, physician recruiters, and ops owners who need fast connectability, clean deliverability, and a workflow that doesn’t break your ATS/CRM.

This is a neutral buyer guide you can share internally. It includes a copy/paste scorecard, a demo question set, and a 2-week pilot plan you can run without guessing.

Quick Answer

Core Answer

Evaluate provider contact data vendors by scoring proof of verification, workflow fit, and pilot outcomes using consistent connect and deliverability metrics across the same cohort.

Key Insight

“Big database” ≠ reach: require definitions, proof of refresh cadence, and evidence the data works in your exact outreach workflow.

Best For

Recruiting leaders buying contact data.

This method is for legitimate recruiting outreach only. Always respect candidate privacy, opt-out requests, and local data laws. Heartbeat does not provide medical advice or legal counsel.

Framework: The Vendor Scorecard: Proof → Workflow → Outcomes

Most vendor evaluations fail because they start with volume (“How many records?”) instead of operational truth (“Will my team reach the right clinicians this week, without burning our domain or wasting dials?”). Use this sequence:

• Proof: What is the vendor actually verifying, how often, and how do they show it?
• Workflow: Can your team use it inside your current stack and process (ATS/CRM, enrichment, dialer, email, suppression)?
• Outcomes: In a short pilot, does it improve connect rate and deliverability rate enough to justify cost and effort?

The trade-off is… vendors can optimize for breadth (more records) or reliability (more verified, usable records). Your scorecard should force that choice into the open.

Diagnostic Table:

Copy/paste this table into a doc and use it live during demos. It’s built to surface “big database” hand-waving and force definitions, proof, and workflow fit.

Minimum export schema (copy/paste requirement):

• Stable person identifier (NPI where applicable)
• License matching status + license state(s)
• Phone fields: number, line type, line tested flag, last verified timestamp
• Email fields: address, deliverability tested flag/status, last verified timestamp
• Refresh cadence fields (or last refresh timestamps) by phone/email
• Suppression/opt-out flag(s) that flow through export and API

Vendor Scorecard uniqueness hook (VENDOR_SCORECARD): Require every vendor to deliver the same one-page “Proof Pack” export (same columns, same NPIs you choose). If they can’t, you don’t have comparable inputs—so you can’t make a fair decision.

Step-by-step method

Step 1: Lock your use case (so the vendor can’t move the goalposts)

Write down the exact workflow you’re buying for. Examples:

• Outbound calling to reach passive physicians during clinic hours (need direct dials and line type clarity).
• Email-first outreach for employed APPs (need deliverability tested emails and suppression).
• Multi-touch sequences (need stable IDs, refresh cadence, and API/Zapier/Make automation).

Also define your “unit of value”: a connected call, a reply, or a qualified screen. If you don’t define this, the vendor will default to record counts.

Step 2: Copy/paste demo questions (use the same set for every vendor)

• “Define ‘verified’ for phone and email. What event changes the status?”
• “Show me a record with line tested metadata and the last verified timestamp.”
• “Show me a record with deliverability tested metadata and how you suppress hard bounces.”
• “What is your refresh cadence by field, and where do I see it in the export/API?”
• “How do you do license matching and handle duplicates or name changes?”
• “Do you key identity to NPI (when applicable)? If not, what’s the stable identifier?”
• “How do opt-outs and do-not-contact flow through exports and the API?”
• “Show your Zapier / Make options for enrichment at the moment of need.”
• “What does ‘healthcare-only’ mean in your product? How do you prevent non-clinician noise?”
• “Can you produce a Proof Pack export with the minimum schema listed above?”

Step 3: Force definitions (especially around “verified”)

Ask the vendor to define these terms in plain language and in export fields:

• Verified phone: What exactly happened to mark it verified? Is it line tested? When?
• Deliverability tested email: Is it only syntax/MX checks, or do they manage bounce suppression and risk? (This is not the same thing as inbox placement.)
• Refresh cadence: How often do they re-check each field, and do you see timestamps?

Require the definitions to map to columns you can store in your ATS/CRM (or at least in a staging table). If it’s not in the data, it’s not real operationally.

Step 4: Validate identity resolution (NPI + license matching)

In healthcare recruiting, identity mistakes are expensive: wrong specialty, wrong state, wrong clinician. Require:

• NPI as a primary identifier where applicable.
• License matching logic (how they reconcile name changes, multiple states, and duplicates).
• Clear handling of multiple practice locations and multiple phone numbers.

Operational note for your CRM/ATS: store NPI as the primary key (when applicable) and treat phones/emails as time-stamped attributes so refresh cadence and last-verified dates don’t get lost.

Ask for a walk-through on one tricky example: a clinician with multiple locations and a group practice switchboard. You’re looking for how they prevent “looks right” data from wasting recruiter time.

Step 5: Run a 2-week pilot that measures outcomes (not vibes)

Heartbeat internal metrics are allowed here as a method, not as numbers: run a 2-week pilot where each vendor gets the same target list and the same outreach rules. Keep it simple and auditable.

1. Pick a cohort: a few hundred NPIs (or your equivalent) from roles you actively recruit. Use the same cohort for every vendor.
2. Split fairly: Randomly assign records to Vendor A vs Vendor B (or run sequentially with the same team and script).
3. Standardize outreach: Same dial attempts per record, same call windows, same email domain, same sequence length.
4. Track suppression: Honor opt-outs and do-not-contact across both vendors during the pilot.
5. Log outcomes: Capture connected calls, human answers, delivered emails, bounces, and replies by vendor source.

Measure this by… outcomes per 100 dials and per 100 delivered emails, not by total records returned.

Step 6: Demand workflow fit (API, Zapier/Make, and operational controls)

Even good data fails if it can’t flow into your system without manual chaos. In the demo, ask them to show:

• API endpoints for lookup/enrichment and how they handle rate limits and retries.
• Prebuilt automation via Zapier or Make (e.g., “new req → pull contacts → push to CRM → create tasks”).
• Export fields for verification timestamps, line type, email status, and suppression flags.

If you can’t automate the boring parts, your recruiters will stop using it—or they’ll use it inconsistently, which makes your pilot results meaningless.

Weighted Checklist:

Use this as your scoring rubric. Total = 100 points. Adjust weights based on whether you’re call-heavy or email-heavy, but keep the structure so vendors are comparable.

Pass/Fail gates (set before you score):

• Must provide verification timestamps (phone and email) in export or API.
• Must enforce suppression/opt-out across export and API.
• Must show NPI-based identity (where applicable) and explain license matching.
• Must support an automation path (API and/or Zapier/Make) that fits your workflow.
• Must allow a cohort-based pilot using your chosen NPIs and your outreach rules.

Common pitfalls

Pitfall 1: Buying “big database” instead of usable reach

Record counts are not reach. Reach is “how many of my target clinicians can I actually contact this week without burning time or deliverability.” Require field-level refresh cadence and proof metadata, or you’re buying a marketing number.

Pitfall 2: Letting the vendor define success

If the vendor’s success metric is “records delivered,” you’ll get a lot of records. Your success metric should be outcomes: connected calls, replies, and qualified screens—measured consistently across vendors.

Pitfall 3: Ignoring suppression and opt-outs until it’s a problem

Suppression isn’t a legal footnote; it’s an operational requirement. If opt-outs don’t flow through exports and API, your team will accidentally re-contact people and create avoidable risk.

Pitfall 4: Not testing workflow friction (the hidden cost)

A vendor can “win” on data quality and still lose in practice if your team has to do extra steps to use it. During the pilot, track how many touches it takes to go from “need contacts” to “outreach sent.”

Pitfall 5: Confusing line type with reachability

Line type helps, but it’s not the same as answer probability. You still need a pilot that measures connects and answers in your call windows with your script.

How to improve results

This section is about making your evaluation repeatable and measurable, so you can defend the decision to finance and your recruiting team.

Metric definitions (use these consistently)

• Connect Rate = connected calls / total dials (e.g., per 100 dials).
• Answer Rate = human answers / connected calls (e.g., per 100 connected calls).
• Deliverability Rate = delivered emails / sent emails (e.g., per 100 sent emails).
• Bounce Rate = bounced emails / sent emails (e.g., per 100 sent emails).
• Reply Rate = replies / delivered emails (e.g., per 100 delivered emails).
• Pilot (definition): a time-boxed, controlled test where vendors receive the same cohort and outreach rules, and you evaluate outcomes using the same denominators.

Measurement instructions (2-week pilot you can actually run)

1. Build the cohort: Choose a single specialty band or role type you’re actively recruiting. Export a clean list with NPI (when applicable), name, state, and employer.
2. Set outreach rules: Same number of dials per record, same call windows, same email sequence length, same sender domain.
3. Instrument tracking: In your dialer/CRM, tag each attempt with vendor source. For email, tag sends by vendor source and capture delivered/bounced/replied.
4. Calculate weekly: Report Connect Rate per 100 dials, Answer Rate per 100 connected calls, Deliverability Rate per 100 sent emails, Bounce Rate per 100 sent emails, Reply Rate per 100 delivered emails.
5. Normalize for effort: Evaluate vendors on outcomes per recruiter-hour as a sanity check (if one vendor requires more cleanup, it should show up here).
6. Decide with gates + score: Apply pass/fail gates first, then use the weighted checklist to pick the best workflow fit.

Decision memo (what to save)

• The vendor’s Proof Pack export (your NPIs, minimum schema included).
• Screenshots or notes of the vendor’s definitions (what “verified,” “line tested,” and “deliverability tested” mean).
• Your cohort definition (how you selected NPIs/roles and any exclusions).
• Your outreach rules (call windows, dial attempts, email sequence, suppression rules).
• Weekly rollups using the pilot results table (so finance and leadership can audit the decision).

Operational upgrades that usually move the needle

• Use verification metadata in routing: Prioritize records with recent verification timestamps and clear line type.
• Separate office vs mobile strategies: Office lines need gatekeeper scripts and call windows; mobiles need concise, compliant outreach.
• Protect your domain: Use suppression, warm sending practices, and monitor deliverability signals in your email tooling.
• Automate enrichment: Use API + Zapier/Make to enrich at the moment of need (new req, new lead), not in giant quarterly dumps.

Outreach Templates:

Use these to keep your pilot consistent across vendors. Consistency is what makes the results defensible.

Call opener (direct-to-clinician)

Script: “Hi Dr. [Last Name]—this is [Name]. I’m reaching out about a [role type] opportunity in [market]. Is now a bad time for a 20-second overview?”

• If yes: “Totally fair—what’s a better time today or tomorrow?”
• If no: “We’re looking for [1-line need]. If it’s not you, who handles these conversations in your group?”

Gatekeeper script (office line)

Script: “Hi—can you help me reach Dr. [Last Name] about a recruiting inquiry? I’m not selling anything. What’s the best way to route a message?”

• Ask for preferred channel: direct line, voicemail protocol, or email format.
• Log the routing info as a data-quality note for the vendor evaluation.

Email 1 (deliverability-safe, short)

Subject: “[Specialty] role in [Market]?”

Body: “Dr. [Last Name] — I recruit for [Org/Client]. Quick check: are you open to hearing about a [role type] position in [market]? If not, reply ‘no’ and I’ll close the loop.”

Email 2 (value + opt-out clarity)

Subject: “Closing the loop”

Body: “Following up once. If you’re not interested, reply ‘no’ and I won’t reach out again. If you prefer a different email/number for recruiting messages, tell me and I’ll update my records.”

Legal and ethical use

Recruiting outreach has real compliance and reputation risk. Build your process so it’s respectful and auditable:

• Honor opt-outs quickly and globally (across sequences, exports, and API pulls).
• Maintain your own suppression list independent of any vendor export/API, so opt-outs stay enforced even if you switch vendors.
• Don’t misrepresent who you are or why you’re contacting someone.
• Use appropriate channels and avoid repeated unwanted contact.
• Document your process: save the vendor’s Proof Pack export and screenshots of definitions shown in the demo so your decision is auditable later.

For baseline guidance, review TCPA considerations for phone outreach and CAN-SPAM requirements for email. See: FCC TCPA overview and FTC CAN-SPAM compliance guide.

Evidence and trust notes

When you’re evaluating data vendors, trust is mostly about process transparency: definitions, timestamps, suppression, and whether the vendor will let you run a fair pilot.

FAQs

What should I ask in a demo?

Use a fixed question set: definitions of “verified,” proof of line tested phones and deliverability tested emails, refresh cadence by field with timestamps, suppression enforcement, and how NPI + license matching works.

How do I run a fair 2-week pilot between vendors?

Use the same cohort (same NPIs), the same outreach rules, and the same tracking tags. Evaluate outcomes per 100 dials and per 100 delivered emails, not total records returned.

What metrics matter most for recruiting outreach?

For calling: Connect Rate (connected calls / total dials) and Answer Rate (human answers / connected calls). For email: Deliverability Rate (delivered / sent), Bounce Rate (bounced / sent), and Reply Rate (replies / delivered).

How do I avoid buying stale data?

Require field-level refresh cadence and timestamps (last verified/last seen). Prefer vendors that support “access + refresh” workflows via API over one-time dumps, and enforce suppression.

Can I evaluate vendors without risking my email domain?

Yes: keep pilot volumes controlled, use suppression, monitor deliverability signals, and track deliverability rate and bounce rate by vendor source. Use tools like Google Postmaster Tools where applicable.

Next steps

• Run the scorecard: Copy the Diagnostic Table + Weighted Checklist into your vendor evaluation doc and use the same demo questions with every vendor.
