ContactOut vs Data Marketers Group: 2026 Comparison
If your last purchased list bounced hard, you already know the delivery model matters as much as the data itself. ContactOut and Data Marketers Group chase the same goal - verified contact data - but the buying experience couldn't be more different. One's a self-serve Chrome extension. The other requires a sales call and delivers a CSV.
Let's break down which one actually earns your budget.
30-Second Verdict
ContactOut wins if you need a self-serve Chrome extension for real-time prospecting with CRM/ATS integrations and an API.
Data Marketers Group wins if you need a one-time custom list for a niche vertical campaign and don't mind a sales call.
What Each Tool Actually Is
ContactOut
ContactOut is a SaaS email finder built around a Chrome extension and search portal. It indexes 700M+ profiles, offers API access with hourly data updates, and integrates with Salesforce, major ATS platforms, and automation tools like Zapier.
Recruiters on Reddit are generally positive about ContactOut, especially for personal email coverage and lower bounce rates versus tools like Apollo or Lusha. Use it if you're an SDR or recruiter who prospects one-by-one from a browser. Skip it if you need bulk data at scale - the "unlimited" plans aren't actually unlimited once fair-use limits kick in, which we'll get to below.
Data Marketers Group
DMG is a custom list vendor. You call sales, describe your targeting criteria, and receive a CSV or XLS file. Their database covers 125M contacts with 44M decision-makers across 57 industry sectors, sourced from public records, SEC filings, surveys, and annual reports.
Use it if you need a one-time list for a specific vertical and prefer someone else to handle segmentation. Skip it if you want self-serve access, CRM integrations, or real-time workflows. G2 lists DMG in a "Lead Generation Companies" context - alongside agencies and services, not self-serve email finder SaaS tools. That positioning tells you a lot about what you're actually buying.
Feature-by-Feature Breakdown
| Feature | ContactOut | Data Marketers Group |
|---|---|---|
| Product type | Self-serve SaaS | Custom list vendor |
| Database size | 700M+ profiles | 125M (44M decision-makers) |
| Data sourcing | Extension + database search; hourly API updates | Public records, SEC filings, surveys, annual reports |
| Deliverability | Lower bounce rates (recruiter-reported) | 72% or 90-95% (conflicting claims) |
| Data refresh | Hourly via API | Monthly (30-day cycle) |
| Integrations | Salesforce, ATS, Zapier | CSV/XLS delivery only |
| Self-serve | Yes | No - contact sales |
| Compliance | - | GDPR, CCPA |
Two things jump out here. First, DMG's deliverability claims contradict each other - the homepage says 72%, while the FAQ page promises 90-95%. That's a gap big enough to wreck a campaign, and neither number inspires confidence when you compare it to what modern SaaS platforms deliver.
Second, ContactOut's "unlimited" email and phone plans come with fair-use caps that aren't obvious until you're already using the product. We've seen this trip up teams who expected true unlimited access and hit walls mid-campaign.
ContactOut caps you at ~2,000 emails/month on "unlimited" plans. DMG can't even agree on its own deliverability rate. Prospeo gives you 300M+ profiles with 98% email accuracy, 30+ search filters, and data refreshed every 7 days - not monthly. All self-serve at ~$0.01/email.
Stop choosing between overpriced caps and unreliable CSVs.
Pricing: Self-Serve Tiers vs Quote Model
ContactOut
| Plan | Price | Includes |
|---|---|---|
| Free | $0 | 5 emails + 5 phones + 5 exports/day |
| $99/mo | "Unlimited" emails + 300 exports/month | |
| Email+Phone | $199/mo | "Unlimited" emails + phones + 600 exports/month |
| Team/API | Contact sales | API access, bulk license, dedicated AM |
Here's the thing: those Email and Email+Phone plans are marketed as "unlimited," but fair-use policies cap you at roughly 2,000 emails and 1,000 phone numbers per month. Fine for a single recruiter. Not fine for a 5-person outbound team burning through lists every week.
If you're evaluating options beyond these two, start with a benchmark list of the best business contact database providers and compare refresh rates, filters, and verification methodology.
Data Marketers Group
DMG doesn't publish pricing. Based on typical list-vendor pricing in this space, expect $0.10-$0.50 per contact depending on volume and targeting specificity. No public tiers, no self-serve checkout - just a sales call.
If you're considering buying lists at all, it's worth reading a safety-first guide on how to purchase email lists for marketing without torching deliverability.
Trust & Reviews
ContactOut has solid review coverage across major platforms. The consensus among recruiters is that it handles personal email discovery well and keeps bounce rates manageable, though power users note the fair-use limits as a frustration.
If bounce rates are the pain point, diagnosing email deliverability issues early will save you weeks of guesswork.
DMG's review presence is a different story entirely. Trustpilot shows a single review dated March 2026 - for a company that claims to have been founded in 2010. Datarade shows zero reviews with an unclaimed profile. DMG's own site claims 600+ startups, 3,000+ sales teams, and 15,000+ businesses - three different numbers with no clear relationship between them. Their Trustpilot profile describes 50M+ records while the homepage says 125M.
Look, when a vendor's own pages can't agree on database size, deliverability rate, or customer count, the data quality conversation is already over. If you still want to test DMG, buy a small batch first and verify it yourself before committing real budget.

When Neither Tool Fits
The numbers back this up in practice. One customer, GreyScout, saw bounce rates drop from 38% to under 4% and pipeline increase 140% after switching. At roughly $0.01 per email with no contracts, it's significantly cheaper than ContactOut's $99-$199/mo tiers and far more transparent than DMG's quote-based model.
If you're building outbound sequences on top of any dataset, using proven drip campaign templates helps you separate “bad data” from “bad messaging” fast.
GreyScout dropped bounce rates from 38% to under 4% and grew pipeline 140% after switching to Prospeo. No sales calls, no fair-use surprises, no conflicting accuracy claims - just 98% verified data with native Salesforce and HubSpot integrations built in.

FAQ
Is Data Marketers Group a SaaS tool?
No. DMG is a custom list vendor - you contact sales, describe criteria, and receive a CSV file. There's no browser extension, search portal, or API. If you need self-serve access with CRM integrations, you'll want a SaaS platform instead.
Are ContactOut's "unlimited" plans really unlimited?
Not exactly. Fair-use caps limit usage to roughly 2,000 emails and 1,000 phones per month on plans marketed as unlimited. Solo recruiters rarely hit these limits, but outbound teams running multi-rep campaigns will.
What's a more affordable alternative to both?
Prospeo offers 300M+ profiles with 98% email accuracy starting free at 75 emails/month. Paid plans cost about $0.01 per email - significantly cheaper than ContactOut's tiers and more transparent than DMG's sales-call pricing. It also includes 30+ search filters, intent data powered by Bombora, and native CRM integrations with Salesforce, HubSpot, and more.
Can I test Data Marketers Group before committing?
DMG doesn't offer a free trial or self-serve sample. You'll need to request a custom quote through their sales team. Given the conflicting deliverability claims on their own site, insist on a small paid test batch before any large purchase.
