01·The Challenge
Every channel produced something. Nothing produced enough.
The client designs and runs corporate offsites and retreats. They had a working business and a familiar problem: every lead channel produced something, but nothing produced enough of the right buyers.
SEM drove the most leads of any source, and converted the worst. 6.5% win rate, $128K average deal. They were paying for volume and getting tire-kickers. Organic and referrals brought better buyers but couldn't scale on demand. You can't tell Google to send you more retreat planners with budget, and you can't tell a referral partner to refer faster.
What they needed was a channel they could point. Specific buyers, specific volume, on their timeline.
02·Why SetWize
A targeting system, not a blast tool.
The client hired SetWize to build and run cold email as a dedicated outbound channel. Not a blast tool. A targeting system: tight ICP definition, verified contact data, sequences written to start conversations with retreat buyers who had real budget, and infrastructure managed to keep every email landing in the inbox.
The bet was simple. If outbound could reach the buyers SEM never would, the deal quality would prove itself.
03·What We Did
Continuous outbound, starting January 2025.
01/Targeting First
Verified before a single send
Every list built against the client's ICP and verified before a single send. Bounce rate held at 0.76% in year one and improved to 0.58% in year two, a fraction of the 2% industry threshold.
02/Conversations Over Clicks
Replies from real buyers
Sequences written to earn replies from qualified buyers, not inflate vanity metrics. The result: 31% of all replies were positive, and roughly 1 in 4 positive replies became a booked meeting.
03/Scale on Proof
Doubled after the results came in
46,945 leads contacted and 183K emails sent in 2025. After the results came in, the client expanded the program. By mid-2026, SetWize had already contacted 56,066 new leads, more than the entire prior year.

#1 revenue source, roughly 37% of total company revenue
All of it at a 135× return on the program investment, with most of the 2026 pipeline still in motion. The channel comparison tells the story. Each email-sourced lead was worth roughly $50K in revenue. SEM leads were worth about $8.4K. Cold email didn't win on volume. It won on reaching buyers no other channel could find.
| Source | Leads | Conversion | Avg Deal Size | Revenue |
|---|---|---|---|---|
| Email (SetWize) | 115 | 13.2% | $388K | $5.8M |
| Organic | 220 | 11% | $155K | $3.7M |
| Referral partner | 75 | 23% | $185K | $3.1M |
| SEM | 305 | 6.5% | $128K | $2.55M |
| Direct traffic | 35 | 11.8% | $125K | $0.5M |
| AI (LLMs) | 5 | n/a | $77K | $75K |
Second-fewest leads of any major channel. First in revenue. Referrals converted at a higher rate, but referrals cap out at whoever happens to refer. Cold email delivered buyers worth twice as much per deal, at nearly double the total revenue, on demand.
And in 2026, they tripled down
After year-one results, investment scaled 3× and outreach volume doubled. The 46 meetings booked by March 2026 nearly match all of 2025 in under half the time.
05·Scale Without the Blowback
312,000+ emails. The sending got cleaner.
The objection to cold email at volume is always the same: it torches your domain reputation and lands in spam. Here's what 15 months of sending actually looked like: 312,000+ emails sent across 103,000+ unique leads.
Bounce rate of 0.76% in year one, improved to 0.58% in year two. The industry threshold for healthy sending is 2%. Most programs degrade as they scale. This one got cleaner.
Bounce rate vs. the 2% healthy-sending threshold
31% of replies were positive in 2025 and 29% in 2026, holding steady while volume doubled. That's not luck. Every list is verified before a single send, sending infrastructure is monitored continuously, and copy is screened against spam patterns before it ships. The boring work is what keeps a quarter-million emails landing in inboxes instead of junk folders.
The proof that quality held at scale: deal size and conversion didn't dilute. Doubling outreach in 2026 produced the same caliber of buyer the program started with.
Methodology & Notes
Client identity. The client is a company that designs and runs corporate offsites and retreats. Their name is withheld from this case study; engagement details are available on request.
Reporting basis. All figures reflect the January 2025 through March 2026 reporting window. The engagement is ongoing, and most of the 2026 pipeline is still in motion, so the return shown should be read as a point-in-time floor.
Channel comparison. Channel figures are drawn from the client's CRM over the same window. Per-lead revenue values divide closed revenue by lead count for each source.
