Evaluating Pre-Listing Lead Platforms: A Question-Driven Checklist

Vendor demos are choreographed to highlight the parts of the product that look impressive and to skip past the parts that do not. This is normal. It is the demo’s job. The agent’s job is to disrupt the choreography with questions the vendor was not planning to answer.

This is the question list. Ask them in order. Ask follow-ups. Push back on non-answers.

Why the demo will not tell you

Three failure modes are systematically hidden in vendor demos. Stale data (the demo pulls a synthetic example dataset, not the real production feed). Weak filtering (the demo shows a curated subset, not the raw output). Poor outcomes (the demo shows the platform, not the cohort-level conversion).

The questions below force these into the open. The vendor that can answer all of them cleanly is the rare honest one. The vendor that dodges is signaling something.

Questions about the data

What is the median age of a lead in your platform, measured from the underlying triggering event (death, probate filing) to the moment it appears in my dashboard? Acceptable answer: under 14 days. Acceptable evidence: a histogram of latency for last month’s cohort.

How do you handle counties where the probate court does not publish filings electronically? If the answer is “we cover the major counties,” ask which counties they cover in your state. Most vendors cover 60-70% of US counties; coverage below that for your target market is a deal-breaker.

How do you resolve the heir contact? The signal is the probate filing; the actionable contact is the executor or beneficiary at their current address. Resolving this requires cross-referencing voter rolls, deed history, and skip-trace data. Vendors that hand wave on this question typically deliver leads whose mailing addresses are 2-5 years stale.

What is your policy on trust-held and TOD-deeded homes? Acceptable answer: filtered out before mail ships. Unacceptable answer: included in the lead count.

Questions about operations

Walk me through, in concrete steps, what happens between a triggering event in my territory and a piece of mail arriving at the heir’s house. Time how long each step takes. The good answer is detailed and adds up to under 14 days. The bad answer is vague and includes phrases like “our team reviews” without specifying what the review involves or how long it takes.

Who designs the mail piece, and how is it calibrated for tone? The vendor should have a defensible approach to grief-window tone. They should be able to show you sample pieces and explain the choices. If they cannot, the pieces are probably generic farming postcards relabeled.

What is your cadence sequencing logic? When does touch one ship relative to the triggering event? When does touch two ship? Touch three? See our piece on heir nurturing sequences for what a good answer looks like.

How do you handle suppression? If a household responds after touch one, does touch two still ship? What about households that move during the sequence? Suppression discipline is a marker of operational maturity.

Questions about outcomes

Show me cohort-level conversion data for last quarter. Pieces mailed, conversations produced, listings signed, closings completed. By month, by county, with the actual numbers.

Almost no vendor will agree to share this in full. The question is still worth asking, because the way the vendor declines tells you something. A vendor that says “we can show you aggregate ranges” is more honest than one that says “our agents typically see” (which is case-study language, not data).

For your county specifically, what was last quarter’s pieces-to-listing conversion rate? If the vendor cannot answer, they are not tracking it, which means they are not managing the channel for outcomes. They are managing it for renewals.

What is your client retention rate at 12 months? At 24 months? A vendor with good outcomes retains 75%+ of clients past year two. A vendor below 50% retention is churning through agents.

Questions about the commercial structure

What does my first 12 months of payment look like? Specifically: upfront, monthly, renewal triggers, what happens at month 12 if I want to cancel.

Are there any per-lead, per-mail-piece, or per-closing fees on top of the subscription? A clean platform has flat monthly pricing that covers data, filtering, mail production, and operations. A vendor that nickel-and-dimes on per-piece pricing on top of subscription is signaling that the subscription does not cover the actual cost.

Is the relationship month-to-month or annual? If annual, what is the cancellation process? See our piece on what listing agents hate about lead vendors for the structural reason annual lockups should be a deal-breaker.

If I refer another agent and they sign up, do I get anything? Most vendors offer a referral program. The structure of the referral program tells you how confident they are in product-market fit.

Specific red flags

Any of these in a single demo should give you pause. Two or more should be deal-breakers.

The vendor cannot or will not state the median age of a lead in their system.

The vendor requires a 12-month commitment with no escape clause.

The vendor sells the same lead to multiple agents in your territory.

The vendor’s pricing includes per-lead or per-mail-piece fees on top of subscription, with no clear cap.

The vendor cannot show you a sample mail piece or describe their tone calibration.

The vendor’s onboarding consists of “here is your login.”

The vendor publishes only case studies, never aggregate cohort data.
