The Problem: Expensive Mediocre Data Was Burning Client Domains

B2B Boosted, an agency running Clay and AI automations for clients, hit a wall when their email provider quoted $18K/year for mediocre data. “We were asked to pay $18K annually for unverified emails that didn't even integrate with Clay. Half the contacts were catch-alls that weren't actually validated. That's when we knew we had to move.”

The data quality was killing client campaigns. “We'd send 2,000 emails and 35% would bounce. Client domains got flagged. We were damaging their infrastructure and couldn't scale volume without destroying deliverability.”

The math didn't work:

“We couldn't grow the agency because we couldn't confidently deliver results,” Tim says. “When client domains get flagged after 90 days, they churn. We needed data that let us scale volume safely and show real ROI.”

Enterprise solutions wanted even more money. “Cognism quoted $15–25K/year. That's insane for a bootstrapped agency. We needed quality at a price that made sense.”

• Bounce rate: 35%
• Client domain flags: regular occurrence
• Pipeline: $70K/year (~$1.3K/week)
• Time building lists: 10+ hours/week
• Volume ceiling: scared to send more than 50K emails/month

The Fix: Unique Data + Domain Protection = Scalable Client Results

Tim switched to Prospeo. “Three things sold me: BounceBan verification that strips spam traps other providers miss, native Clay integration, and pricing that was a fraction of the $18K quote.”

The difference was immediate:

1. BounceBan exclusivity and spam-trap removal

“Prospeo's data isn't recycled lists everyone else has. BounceBan gives us truly unique emails, and the spam-trap and honeypot removal meant we stopped triggering client domain flags. Other providers call catch-alls ‘valid’ and pass them through. Prospeo actually verifies them. That's the difference between 35% bounce and under 2%.”

2. Scale safely at high volume, low cost

“We went from terrified to send 50K emails/month to comfortably sending 300,000+ emails/month across all client campaigns. Bounce rate stayed under 2%. And we're paying a fraction of what Cognism or the old provider wanted. The ROI is a no-brainer: better data, lower cost, way higher volume.”

3. Enterprise-grade accuracy

“No more ‘valid but wrong inbox’ traps at big companies. We're not wasting touches on catch-all aliases that go nowhere. When we target a VP at a Fortune 500 client, we're reaching the actual person. That's what agencies need to deliver results clients will pay for.”

The workflow became scalable. “Build a 500-contact list in 20 minutes instead of a full day. Export 20K+ verified emails and launch immediately. 35+ enrichment points per contact, including timezone for local send optimization. We're operating like an enterprise agency with data quality to match.”

The Results: $70K to $300K+ Annual Revenue, Zero Domain Burns

Client campaign metrics improved across the board:

Client performance:

Agency growth:

“We more than quadrupled revenue with the same team,” Tim says. “The unlock was showing prospects we could deliver results. When you demo a client campaign with 92% deliverability and qualified meetings, selling gets easy. When their domain stays clean after sending 50K emails in a month, they stay for years.”

Domain protection became the retention driver. “Going from 35% bounce to under 2% isn't just better performance. It's the difference between a client churning after 90 days because we burned their domain versus staying with us for years because their infrastructure is protected.”

The cost savings were massive too. “We're paying a fraction of the $18K/year quote and getting better data. That's pure margin improvement. Easy money.”

• Email deliverability: 67% → 92%
• Bounce rate: 35% → under 2%
• Total monthly volume: 50K → 300,000+ emails (6x increase, safely)
• Meeting qualification rate: 40–50% → 80–90% with actual budget authority
• Domain flags: regular issue → zero in 8 months
• Before: $70K annual revenue (~$1.3K/week)
• After: $300K+ annual revenue (~$5.8K/week)
• First 3 weeks after switching: $120K in new pipeline
• Time on list building: 10 hrs/week → 4 hrs/week

What’s Next

B2B Boosted is now taking on bigger clients confidently. “We can promise 300K+ emails/month without domain risk. That unlocks deals with companies who need serious volume.”

Testing new verticals is instant. “I built a list of 800 Clay users in brick-and-mortar niches in 30 minutes. Before, that would've taken weeks. Now we experiment fast and show prospects results in days.”

Tim's advice to agency owners: “If your data bounces 30%+ or you're scared to scale volume, you're leaving money on the table. The difference between $70K and $300K isn't working harder. It's having data that protects client domains, scales safely, and costs a fraction of enterprise pricing. That's what lets you win bigger clients and keep them for years.”
