How GreyScout Doubled Their Sales Team Without Burning More Domains

The Problem: Can't Scale Outbound When Your Domains Are Flagged

GreyScout helps brands fight grey market sellers. Great product, clear value prop. But their outbound was broken. “We had two reps sending emails, and our domains were already flagged. Bounce rate was 38%. We were damaging something that would take months to fix.”

The board wanted growth. “We had budget to hire three more reps. But I couldn’t bring on new people and hand them broken infrastructure. They’d either make the domain situation worse, or spend months ramping while we fixed it.”

The root cause was data quality. “We were using a mix of free tools and cheap databases. About 40% of emails were wrong. Old contacts, people who’d left, bad formats. Every send damaged our reputation more.”

Cold calling wasn’t much better. “Office numbers meant fighting assistants. Connect rate was maybe 6–7%. New reps would burn out before they got momentum.”

The math didn’t work. “We needed to triple our pipeline to justify the new headcount. But scaling broken outbound 2.5x would’ve just killed our domains faster. We needed to fix the foundation first.”

The Fix: Clean Data Before Scaling Headcount

Found Prospeo while researching domain recovery. “What stood out was the verification. Triple-verified emails, not just the data. And direct mobiles so reps could actually reach decision makers.”

They ran a test before hiring. “I built a 200-contact list of our exact ICP. Sent it through our sequences. Bounce rate was 3%. That’s when I knew we could scale safely.”

Three things changed their approach:

  • Domain recovery first: “We paused bad data sources and switched entirely to Prospeo. Bounce rate dropped to under 4% in the first month. Domain reputation recovered in six weeks instead of six months.”
  • Mobile numbers for new reps: “New hires could call direct lines instead of fighting gatekeepers. Connect rate went from 6–7% to 21%. Ramp time cut in half because they were having real conversations week one.”
  • Confidence to scale volume: “Before, more sends meant more damage. With verified data, we could increase volume safely. Five reps sending 3x the emails with better deliverability than two reps had before.”
The Results: 2 to 5 Reps, Cleaner Pipeline, Domains Protected

The numbers flipped in 90 days:

  • Team scaling: Sales team: 2 → 5 reps; Ramp time: 8–10 weeks → 4 weeks; Pipeline: up 140% (more than doubled despite less than tripling team)
  • Infrastructure: Bounce rate: 38% → under 4%; Connect rate: 6–7% → 21%; Domain health: flagged → excellent in 6 weeks
  • Quality: Meeting qualification rate: 45% → 78%; Time per rep on list building: 8 hrs/week → 1 hr/week
What’s Next

“We went from ‘can we even do outbound?’ to confidently scaling the team. New reps hit quota faster because the data actually connected them to real buyers.”

The mobile numbers were critical for onboarding. “New SDRs had 15–20 conversations their first week instead of 3–4. That’s when you know if someone can sell. Before, we couldn’t tell if low performance was the rep or the broken infrastructure.”

Domain health staying clean was the unlock. “We’re sending 4x the volume we were six months ago. Deliverability is better than when we had two people. That’s what verified data does.”

GreyScout is planning to add two more reps next quarter. “We have the infrastructure to scale now. List building takes an hour per week instead of half a day. Reps spend time selling, not fixing bad data.”

Advice to sales leaders hiring into outbound: "Don't scale broken infrastructure. Fix your data first, then hire. We almost made the mistake of bringing on three people before cleaning up our domains. That would've been six months of ramp time wasted and probably $50K in lost productivity. Prospeo let us build the foundation, then scale confidently."
