When evaluating Account-Based Marketing (ABM) platforms, many companies turn to 6sense for its promise of intent data and orchestration. But customer reviews and user feedback highlight serious gaps in 6sense’s offering that limit effectiveness, create frustration, and ultimately hinder ROI.
Are these gaps a hurdle to your team adopting 6sense for ABM? Evaluate the pros and cons before making an investment in the ABM platform that best fits your needs.
6sense Data Quality and Coverage Issues
6sense reviews often mention problems with data accuracy and completeness, including outdated, inaccurate, or missing contact information. Intent signals are of little value when marketing and sales teams can't target and engage the right people within an account.
“...out of 5 contacts 2 are good, the rest are obsolete.” - G2 Review
ZoomInfo Marketing offers the most robust global B2B database, spanning 110M+ companies and 420M+ contacts, backed by our proprietary Identity Graph. Our intent and buying signals are enriched with buyer-level context, making them precise & actionable for you go-to-market teams
6sense Usability and Adoption Challenges
Customers who leave 6sense reviews also report struggles driving user adoption, noting that sales teams resist using the platform and calling out confusing interfaces, contextless recommendations, and workflows that don't align with how they actually sell.
“Has anyone used 6Sense successfully? … Me and my colleagues found it completely useless and were shocked to hear how much it cost” - Reddit
ZoomInfo’s GTM Intelligence Platform provides intuitive workflows, transparent scoring, and actionable insights that sales teams love. With implementation times under three weeks, versus 60+ days for 6sense, your teams see value immediately without requiring dedicated administrators.
6sense Integration Gaps
Some reviews of 6sense reveal customer dissatisfaction with the tool’s intent scoring as a "black box." Sellers report receiving account flags without understanding why, and contact-level details can be missing or irrelevant. This makes it difficult for sales teams to craft meaningful outreach or build trust in the platform.
“Some of the leads that came in had little to no information about the customer” - G2 review
ZoomInfo’s approach to scoring and buying signals provides reps with full transparency, showing exactly which buying signals or intent topics led to an account recommendation.
All of ZoomInfo’s account recommendations include the context sellers need to understand and engage an account, including person-level insights, verified contact information, and additional buying signals such as hiring trends, earnings insights, and champion tracking.
6sense High Cost and Lack of ROI
6sense reviewers also note that it can be among the most expensive tools in a martech stack. Some customers struggle to prove ROI while feeling locked into long-term contracts.
“Overexpensive way to do display ads” - G2 Review
ZoomInfo’s flexible packaging aligns with your business needs and growth, and customers consistently report clear ROI, including an average increase in connect rates of 91%, accelerated pipeline velocity with 21% shorter deal cycles, and 83% larger deal sizes thanks to ZoomInfo Copilot.
6sense DSP and Advertising Issues
6sense reviews and user reports highlight complaints that its Demand-Side Platform (DSP) doesn’t live up to expectations, with users reporting poor targeting accuracy, ads appearing on irrelevant or low-quality sites, and minimal measurable impact on pipeline generation.
“Data model isn't as good as it used to be … Advertising network drives zero results or lift.” - G2 Review
ZoomInfo partners with industry-leading DSPs to ensure precision targeting and premium ad placements. Our advertising campaigns are powered by the same high-quality data that drives our platform, ensuring your ads reach the right buyers at the right time with relevant messaging.
6sense International Coverage
For companies with international operations, 6sense's coverage outside North America is often viewed as limited, making it relatively ineffective for global ABM strategies and multi-region go-to-market teams.
“Data from the platform is not accurate for any region outside of US” - G2 Review
ZoomInfo's global database covers 110M+ companies across the globe, offering comprehensive international coverage. Our compliance-first approach ensures your global teams can execute scalable, compliant ABM campaigns across all major markets while maintaining data quality and accuracy standards.
Is 6sense Worth It?
While 6sense may have been early to the ABM category, customer feedback reveals shortcomings that can limit effectiveness and ROI.
