Outbound System vs. ListKit
Offering expert cold email lead generation as a service has been our obsession and core business model since 2021. For ListKit (primarily a data platform), it's a side business.

Why Outbound System
Why Outbound System
Why Are People Switching From ListKit to Outbound System
Ex-ListKit users say our cold email infrastructure peforms better and is more reliable over the long term.
Core Business Focus Reality
ListKit sells data. We generate leads. Their cold email setup service exists as a secondary service, it’s not their main business model. Our entire company was built with one mission: generating consistent revenue through cold email. When your growth depends on reliable lead flow, would you rather work with dedicated specialists? Or someone who offers it on the side?
Proven ROI Focused Copywriting
ListKit's sequences get replies. Ours drive revenue. While they provide standard templates as part of setup, we engineer niche-specific campaigns with proven frameworks and offers tested across millions of sends. Our exclusive AI personalization technology creates a custom line for each prospect that boost response rates by 2.8x on average.
Superior Cold Email Infrastructure
ListKit's infrastructure (30-90 inboxes sending 20+ emails daily each) violates email provider best practices, guaranteeing periodic collapse. Our architecture (350 dedicated Outlook inboxes sending just 3 emails daily each) maintains a pristine sender reputation. The difference? Consistent pipeline vs. weeks of zero results while rebuilding or going to spam.
Multi-Source Waterfall Data Sourcing
At Outbound System, we access the entire market. LitKit sells you credits to just one data source. Our 9-step waterfall enrichment process pulls from multiple specialized B2B databases to find the most accurate contact information available anywhere. You'll reach up to 40% more B2B decision-makers with dramatically higher accuracy (and the same triple-validation engine).
Ongoing Infrastructure Management
ListKit sets it up. You fix it when it breaks, because you “own” it. With Outbound System, our team continuously monitors and optimizes your campaigns, addressing technical issues before they impact performance. Your choice: become a part-time email technician or focus entirely on closing deals while we handle everything else.
All-Inclusive Simple Pricing Model
ListKit's costs add up fast: $1,500 setup PLUS $150-$450 yearly for domains you need to purchase separately PLUS $600-$1,400/mo. Our simple pricing model includes everything: custom domains, superior infrastructure, ongoing management, and optimization for the same $1,500 setup fee with lower monthly costs. Save thousands while eliminating headaches.
