We run the entire cold email engine for you - and every lead that lands with your team is already vetted, interested, and ready to talk. You only pay for the ones that qualify.
Trusted by companies including
We own every step - infrastructure, targeting, sending, and qualification - so your team only ever touches leads worth talking to.
We build your sending engine from scratch on dedicated infrastructure - completely separate from your main domain, so your company's reputation is never at risk.
We map your exact ICP, build a verified lead list around it, and write copy angles that sound like a person - not a template - so replies come from real buying intent.
Campaigns go out in controlled waves to protect deliverability while volume scales. Every week we kill what's flat, double down on what's working, and report it back to you.
Interested replies get qualified against the criteria we agreed with you upfront. The warm, qualified leads land with your team - full context included - ready for you to close.
Every number below is pulled straight from a live campaign workspace - full funnels, receipts included. These campaigns were delivered by our founding team as Shields Outbound; click through any case study for the complete breakdown.
HDM runs retention email for high-growth Ecom brands. We ran a cold email engine built for scale - 494,307 sends in controlled waves - and kept the bounce rate at a clean 1.52% while volume climbed.
Engagement Amplified gets Ecom brands cited by ChatGPT, Claude and Perplexity - a brand-new category with no existing demand. We created it: 215 Ecom brands raised their hands for AEO, and 78 of them turned into booked calls.
A brand-new AEO consulting practice with zero pipeline. We ran a lean, sharply-targeted campaign, worked all 498 replies by hand - and the first booked call to close became Austin's first signed client.
"I just had the call and closed the deal. First Closed Won ✅ … LFG"
"How much was the deal worth?"
"$6,500"
"Awesome to get our first one under our belt."
CLPR puts brands everywhere at once with a community of 8,000+ clippers. We ran the volume engine behind their pipeline - 105,460 sends - and worked all 1,082 replies by hand into calls and closed retainers.
"Another highly interested prospect - straight from the campaign 🔥"
"Call done with a great lead - 'you guys can send me the invoice.'"
"First invoice sent to a newly-closed client 💯"
Squash sells a governance-first AI technician to MSPs - a cautious, technical buyer. We built the outbound engine that reached the right MSP decision-makers at scale and turned attention into calendared demos, without touching their brand or deliverability.
No monthly fee, no paying for effort. Every invoice maps to a lead that met your criteria.
"Great results, great experience. James and the Shields Outbound team have helped my company Essence Retention book hundreds of sales calls over the past few months. Their attention to detail, professionalism, and most importantly; results, have been instrumental to the growth of our agency."
"Booked 16 last month and 3 closed, I really recommend their services and the attention to detail. I have seen a good ROI on this and I will be continuing to work with Shieldsoutbound and their team."
"Where an ad agency targeting financial services, so it's a bit trickier than a normal campaign despite that James and Thomas helped us book just over 40 appointments in the 90 days working with them. Thanks lads"
ColdToClosed is a lean, founder-led team. There are no layers of account managers and no juniors learning on your budget - the people who build your campaigns are the people who answer your messages.
We started the agency because most outbound is broken. Retainers reward activity instead of outcomes: agencies get paid the same whether your calendar fills up or not. So we flipped the model - we only get paid when a warm, qualified lead lands with your team.
Everything stays in-house: the sending infrastructure, the lead lists, the copy, the reply handling. That's how the numbers in our case studies happen - and why every one of them is public, receipts included.
Every campaign we run gets judged on one thing: did it put real opportunities in front of your team? That's the bar. If we don't hit it, you don't pay - simple as that.
Pay per qualified lead. No retainer, no paying for activity - we only win when you do.
Infrastructure, lists, copy and reply handling - built and run by our own team, never outsourced.
Our case studies are public, with full funnels and receipts. That's the standard we hold ourselves to.
Before launch, we agree qualification criteria with you - company size, budget, decision-maker, and fit for your offer. Only leads that meet those criteria get handed off, and if a lead doesn't meet them, you don't pay for it.
Infrastructure and warm-up take the first 2–3 weeks. Campaigns typically launch inside the first month, with the first qualified leads usually following shortly after launch.
Correct - you pay per qualified lead, not a monthly fee. That means our incentives are exactly aligned with yours: we only make money when you get leads worth talking to.
No. We send from separate, dedicated domains and inboxes that we buy and warm for the campaign - your main domain is never touched.
We hand the qualified lead straight off to you with their contact details and the full context of the conversation, so you can take it from there.
On the intro call we'll map your ICP, agree what "qualified" means for your offer, and show you exactly how the engine would run for you.
