Sound Familiar?
Outreach never reaches the right inbox, and your sender reputation takes the hit.
Your message lands with someone who can't move the deal forward.
Reps spend valuable time verifying contacts instead of selling.

CSG (Chain Store Guide) has spent over 90 years helping sales teams connect with decision makers in retail and foodservice. CSG Blue is our most advanced offering yet.
We rebuilt our retail and foodservice contact data from the ground up, adding new data sources, tightening our validation process, and upgrading our verification technology, so every contact you reach out to has been carefully reviewed and confirmed.
Whether you're prospecting into grocery chains, mass merchants, restaurant groups, or foodservice operators, when you see the Blue tag you know that contact has passed our most rigorous verification checks. No guesswork. Just accurate retail and foodservice contact data, ready to work.
How It Works
Every CSG Blue contact receives an enhanced level of verification by our research team, going beyond standard checks.
We upgraded our verification technology to catch inaccuracies that standard processes miss.
Contacts are categorized by depth of research, so you always know the confidence level behind every record.
A simple signal that means a lot, this contact has passed our highest level of validation and is ready for outreach.
Reach verified decision makers faster and start discussions that actually go somewhere.
Higher accuracy means more of your outreach lands in the right inbox.
Stop chasing bad contacts and put that time back into your pipeline.
Spend less time validating contacts and more time closing.
CSG Blue is our highest level of contact verification. It represents the most thorough research, the deepest validation, and the most trusted contact data we offer. Every CSG Blue record has been through additional layers of review, so when you see the Blue tag, you can reach out with confidence.
CSG (Chain Store Guide) has been in business for over 90 years, helping sales teams find and connect with the right decision makers. CSG LeadSearch is our contact database platform, built on decades of experience and continuously refined to deliver more accurate, more reliable data. CSG Blue is the most advanced level of contact verification we've ever offered, and it's the next step in that long history of helping teams prospect smarter.
Most contact data providers give you a record and move on. CSG Blue goes further with multiple layers of verification, tiered confidence levels so you always know the quality behind a contact, and ongoing monthly email health validations to keep data accurate over time, not just at the point of download. The result is contact data you can actually rely on, not just use once and hope for the best.
CSG Blue contacts go through a multi-step process that combines our research team's enhanced review with advanced validation technology. Contacts are categorized based on the depth of research completed, and only those that meet our highest standards receive the Blue tag. This means every Blue-tagged contact has been individually reviewed, not just run through an automated check.
Contact data decays fast, industry estimates suggest up to 30% of B2B contact data becomes inaccurate every year. That's why CSG Blue includes monthly email health validations. Your contacts are continuously monitored after you access them, so you're not working from a static snapshot that degrades over time.
CSG offers multiple levels of contact verification based on the depth of research. All records meet our quality standards, but CSG Blue represents the highest tier, the most thorough review, the most layers of validation, and the greatest confidence in accuracy. Think of it as the difference between verified and thoroughly verified.
