Comparison Table
Marts & Lundy
agencyFundraising consulting firm with expertise in campaign planning and donor strategy.
Acquisition-list packaging that translates prospect research into campaign-ready targeting fields.
Marts & Lundy supports donor acquisition strategy execution through prospect identification and prospect research that is structured for campaign use, including list fields that map to acquisition workflows. Production work focuses on refining targets by propensity and fit signals, and then packaging those outputs for use in direct mail acquisition and digital acquisition planning. The strongest fit appears when a team needs ongoing new-donor pipeline development with consistent audience definitions across cycles.
A tradeoff is that deeper automation and API-led provisioning are not the centerpiece of the service experience, so internal systems integration effort may fall more heavily on the client. Marts & Lundy is a better usage situation for organizations that can operationalize delivered prospect lists into CRM and campaign tools without requiring the vendor to own end-to-end data plumbing.
- +Research-to-list delivery makes acquisition targeting immediately campaign-ready
- +Prospect refinement supports multiple acquisition channel tests without rebuilding logic
- +Suppression-aware list construction reduces avoidable waste across runs
- +Consistent production output suits ongoing new-donor pipeline goals
- –Limited emphasis on API-driven provisioning and automation from the service layer
- –Client teams must map delivered fields into CRM and campaign systems

Best for: Fits when teams need consistent prospect research outputs that convert into acquisition lists each cycle.
Campbell & Company
agencyFundraising consulting firm offering campaign planning, major gifts, and donor acquisition.
Research-to-target mapping that standardizes prospect selection rules across direct mail and digital acquisition.
Campbell & Company fits organizations that need managed donor acquisition rather than internal-only list building, especially when prospect research quality must translate directly into targeting rules. The service supports acquisition program design that links prospect identification to selection decisions for mail and online channels. The workflow also centers on contact suppression and list hygiene so that donor file growth does not rise through duplicates or inappropriate recontacts.
A tradeoff is that donor acquisition outcomes depend on campaign documentation quality and ongoing governance of targeting inputs, not just on the initial build. Campbell & Company works best when a fundraising or revenue operations team can provide clear donor journey goals and review segmentation assumptions between acquisition waves. The strongest usage situation is when teams want acquisition throughput with consistent standards for research-to-target mapping across multiple campaigns.
- +End-to-end workflow ties prospect research to channel execution
- +Suppression and list hygiene reduce recontact waste
- +Campaign reporting focuses on conversion signals from acquisition
- +Targeting decisions stay consistent across mail and digital
- –Needs disciplined governance of targeting inputs between waves
- –API and automation surface is not the primary delivery mechanism
- –Tighter fit for managed acquisition than DIY internal execution
- –Iteration cycles may lag if feedback arrives late

Best for: Fits when fundraising teams want managed prospect targeting across mail and digital with conversion-focused oversight.
DonorSearch
specialistProspect research and donor acquisition firm specializing in wealth screening and capacity ratings for nonprofits.
Managed prospect research that produces acquisition-ready lists matched to campaign selection criteria.
DonorSearch helps teams run prospect identification and wealth screening to produce acquisition lists aligned to campaign criteria such as giving capacity and inferred donor likelihood. Delivery quality tends to track the clarity of input requirements and the stability of those requirements across cycles because list construction depends on agreed selection fields. Engagement fit is strongest for organizations that can supply source data for suppression and segmentation decisions, then use the returned lists for direct mail acquisition or digital prospecting.
A tradeoff appears when internal teams require deep automation around data ingestion, because DonorSearch’s value centers on managed research and curated list outputs rather than a fully self-serve platform experience. DonorSearch works best when a team plans enough lead time for research turnaround and handles downstream governance for attribution fields like campaign identifiers and landing page mapping.
- +Acquisition-first prospect research that turns criteria into usable outreach lists
- +Wealth screening outputs support donor journey mapping for new-donor targeting
- +Managed delivery reduces internal coordination across research and list builds
- +Consistent campaign file structure supports repeat selection logic
- –Limited indication of a self-serve API surface for list regeneration
- –Tight input governance is required to keep suppression and selection aligned

How to Choose the Right Donor Acquisition
We separate donor acquisition options by how directly they connect tracking to execution, and how much control they give you over audience, consent, and attribution. In practice, differences show up fastest in data freshness, attribution discipline, and workflow automation under a tight admin and governance layer.
Donation and first-gift tracking
Why it matters
Donation and first-gift tracking is what makes donor acquisition measurable, not just reported. When first-gift events link cleanly to campaigns, teams can improve what actually produces new donors.
How to check
Ask the demo to show how a donation becomes a first-gift status, including what happens when gifts occur later. Request a sample report that filters “new donor” by campaign and date range, and confirm what fields define the trigger.
UTM and source attribution controls
Why it matters
UTM and source attribution controls determine whether donor acquisition results stay trustworthy across channels and team edits. If attribution rules are inconsistent, you will see false winners and misallocate effort.
How to check
In the demo, inspect how the product stores campaign parameters and whether you can enforce allowed values. Try importing two donor files with different source labels and confirm which one the system keeps for attribution.
Audience build and suppression handling
Why it matters
Audience build and suppression handling prevents donor acquisition lists from re-contacting people you already have, or who should not be solicited. Good suppression reduces wasted spend and improves data quality.
How to check
Request a workflow where you build a prospect list for acquisition and apply exclusions. Ask how exclusions are defined (for example, existing donors, opted-out, or unreachable) and how the system logs what was suppressed and why.
Consent-aware contact rules
Why it matters
Consent-aware contact rules protect donor acquisition from incompatible outreach. If consent is inconsistent across channels, you will either violate rules or lose response rate by over-suppressing.
How to check
Show a contact rule view for an acquisition campaign and confirm how consent flags gate channel eligibility. Run a scenario: one record with conflicting consent states, and ask what the outreach decision becomes.
Automation and API for campaign ops
Why it matters
Automation and API surface shorten the loop between donor acquisition tests and execution. When the system can ingest updates and trigger tasks reliably, you avoid manual mismatches that break attribution and suppression.
How to check
Ask what can be automated via API: campaign creation, audience export, event ingestion, and status updates. Request a documented sandbox or staging workflow where you can replay one acquisition event stream end-to-end.
RBAC, audit logs, and change history
Why it matters
RBAC, audit logs, and change history matter because donor acquisition requires tight oversight across teams who touch audiences and tracking. When you can trace who changed what and when, you can fix attribution and suppression issues quickly.
How to check
In the demo, verify role controls for who can edit campaigns, exports, and attribution rules. Then run an edit to an audience definition and confirm you can review an audit log showing the prior and updated state.
Red flags
- Donation and first-gift tracking won’t explain how delayed gifts are classified
- UTM and source attribution controls can’t be enforced or audited
- Audience build ignores suppression or gives unclear reasons for exclusions
Fit by situation
- If you run multi-channel prospecting tests, prioritize Donation and first-gift tracking to keep results comparable.
- If your teams touch campaigns and tracking often, prioritize RBAC, audit logs, and change history to reduce attribution drift.
- If you manage outreach eligibility carefully, prioritize Consent-aware contact rules so acquisition stays compliant and efficient.
