GTMData vs LeadMagic: A Detailed Comparison for GTM Teams

If you run outbound sales or manage GTM data pipelines, you have probably used LeadMagic. It is one of the more popular pay-per-result enrichment tools on the market, and for good reason: the pricing is transparent, the API is fast, and it plugs into Clay and other orchestration platforms without much fuss.

But LeadMagic is not the only option anymore. GTMData launched in 2025 with a similar pay-per-result credit model, lower prices at every tier, and a few features that LeadMagic still does not offer, including catch-all email validation and native HubSpot integration. In this article we will walk through every dimension that matters when choosing between the two so you can make the right call for your team.

Overview of Both Platforms

LeadMagic

LeadMagic positions itself as a data enrichment platform for revenue teams. It offers email finding, email validation, company enrichment, and a handful of other endpoints. Credits are consumed only when a result is returned, meaning you do not pay for misses. LeadMagic integrates well with Clay via HTTP API actions and has a solid reputation in the sales ops community. Most users know it as a cost-effective alternative to ZoomInfo or Apollo for one-off lookups and enrichment pipelines.

GTMData

GTMData is a newer entrant focused specifically on email finding and email validation. Like LeadMagic, it uses a pay-per-result credit model where you are never charged when a lookup fails. Where GTMData differentiates is on price, catch-all email validation, a built-in HubSpot integration for syncing validation results directly into your CRM, and soft rate limits that eliminate hard-error failures in orchestration tools like Clay.

Pricing Comparison

Both platforms sell credits in monthly tiers. Each credit is consumed when a successful result is returned, whether that is a found email address or a validation result. Neither platform charges you for lookups that fail. The key difference is that GTMData is approximately 18% cheaper at every tier. Here is the full breakdown:

At the 100K tier the difference is $150.99 per month, or over $1,800 per year. For teams running high-volume enrichment pipelines, those savings compound quickly. And because neither platform charges for failed lookups, the effective cost per usable result is even more favorable on GTMData since you are paying less per credit to begin with.

Both platforms also offer the ability to upgrade or downgrade monthly without long-term contracts. There are no annual lock-ins on either side, which makes it easy to test GTMData for a month and compare results against your current LeadMagic spend.

Feature Comparison

Price matters, but it is not the only thing that matters. Here is a side-by-side look at the features that GTM teams care about most.

The headline differences are catch-all validation, HubSpot integration, and soft rate limits on GTMData versus company enrichment on LeadMagic. If your primary use case is finding and validating emails for outbound, GTMData covers everything you need. If you also need firmographic data like employee count and revenue, LeadMagic has more endpoints for that today.

Catch-All Email Validation

Catch-all domains are one of the biggest headaches in email validation. A catch-all mail server accepts every address sent to it, so a standard SMTP check always returns “valid” even if the specific mailbox does not exist. This means traditional validators, including LeadMagic, typically return an “unknown” or “catch-all” status and leave you guessing.

GTMData goes a step further with proprietary catch-all validation. Using a combination of behavioral signals, pattern analysis, and historical data, GTMData assigns a confidence score to catch-all addresses so you can decide whether to include them in your outreach. For teams sending high volumes of cold email, this alone can improve deliverability rates by reducing bounces from bad catch-all addresses.

Credit Model: Pay Only for Results

Both GTMData and LeadMagic use a pay-per-result credit model. You purchase a monthly credit allotment and each successful lookup, whether it is an email find or a validation, consumes one credit. If the lookup fails, meaning no email is found or the validation cannot be completed, no credit is deducted.

This is a meaningful advantage over platforms like ZeroBounce or NeverBounce that charge per API call regardless of outcome. When you are running enrichment on large lists where match rates might be 60-70%, the pay-per-result model can save you 30-40% compared to a per-call pricing structure.

The difference between the two is simply price. At the 10,000 credit tier, GTMData charges $79 versus $99.99 for LeadMagic. That is $0.0079 per result versus $0.01 per result, a 21% saving that scales linearly with volume.

Rate Limits: Hard vs Soft

This is one of the most underappreciated differences between the two platforms. LeadMagic enforces hard rate limits. If you exceed them, your API calls return a 429 error and your enrichment pipeline stops. In Clay, this means rows fail with an error and you either have to re-run them manually or build retry logic into your workflow.

GTMData uses soft rate limits. Instead of returning an error when you hit the limit, the API simply slows down your requests by adding a small delay. Your pipeline keeps running, just at a slightly reduced speed. In practice, this means zero errors in Clay, zero failed rows, and zero manual intervention. For teams running enrichment overnight or in large batches, this is a significant quality-of-life improvement.

HubSpot Integration

GTMData offers a native HubSpot integration that lets you validate emails directly from your CRM. Connect your HubSpot account, select a list or filter of contacts, and GTMData will validate every email address and write the result back to a custom property on the contact record. There is no export, no CSV upload, and no middleware required.

LeadMagic does not currently offer a native HubSpot integration. To achieve the same result you would need to export contacts from HubSpot, run them through LeadMagic’s CSV validation tool or API, and then re-import the results. That workflow is functional but adds friction, especially for ops teams managing ongoing list hygiene.

If HubSpot is your CRM and you need to keep email validation statuses up to date as contacts flow in, GTMData’s integration saves meaningful time and eliminates a manual step that often gets forgotten.

Speed Comparison

Both platforms are fast. LeadMagic typically returns email validation results in 1-3 seconds per request and email finder results in 2-5 seconds. GTMData is comparable, with validation averaging 1-2 seconds and email finding averaging 2-4 seconds. In practice, the difference is negligible for most workflows.

Where GTMData has an edge is in batch processing through its dashboard. You can upload a CSV of up to 100,000 rows and the system will process them in parallel, typically completing a 10,000-row validation job in under 5 minutes. LeadMagic also supports CSV uploads but the processing speed varies depending on the endpoint and current load.

API Design

Both APIs are RESTful and well-documented. Here is a quick look at finding an email with GTMData:

POST https://api.gtmdata.com/v1/find
Content-Type: application/json
Authorization: Bearer YOUR_API_KEY

{
  "first_name": "Jane",
  "last_name": "Doe",
  "domain": "acme.com"
}

And validating an email:

POST https://api.gtmdata.com/v1/validate
Content-Type: application/json
Authorization: Bearer YOUR_API_KEY

{
  "email": "jane.doe@acme.com"
}

Both endpoints return JSON with clear status fields, confidence scores, and metadata. The API is easy to integrate with Clay, Make, Zapier, or any custom code. LeadMagic’s API follows a similar pattern with slightly different field names but comparable ease of use.

When to Choose Each

Choose GTMData if:

• You want the lowest cost per result across all volume tiers
• You need catch-all email validation to reduce bounces
• You use HubSpot and want native CRM integration for email validation
• You use Clay and want zero-error enrichment with soft rate limits
• Your primary use case is email finding and email validation

Choose LeadMagic if:

• You need company enrichment data (employee count, revenue, industry) in addition to email
• You rely on LeadMagic-specific endpoints that GTMData does not yet offer
• You have an existing workflow tightly coupled to LeadMagic’s API and the switching cost outweighs the savings

For the majority of GTM teams whose primary enrichment need is finding and validating email addresses, GTMData delivers the same core functionality at a meaningfully lower price with a few features that LeadMagic does not currently match.

The Bottom Line

LeadMagic is a solid tool and we have no interest in pretending otherwise. It pioneered the pay-per-result model for email enrichment and has earned its reputation in the sales ops community. But competition is healthy, and GTMData brings genuine improvements: lower pricing at every tier, catch-all validation that most competitors skip, a native HubSpot integration that eliminates CSV roundtrips, and soft rate limits that make Clay workflows bulletproof.

If you are currently spending $799.99 a month on 100K LeadMagic credits, you can get the same volume on GTMData for $649 and gain catch-all validation and HubSpot sync in the process. That is $1,800 saved per year before you factor in the operational time saved by the HubSpot integration.

The best way to evaluate is to try both. GTMData offers a free tier so you can test the API, validate a batch, and compare results against LeadMagic side by side. No credit card required.
