What clients say
Results speak for themselves
"
We were spending $4K/month on an SDR who booked maybe 3 meetings. Coldflows books us 8-12 qualified calls a month on the Growth plan. The ROI isn't even close.

I tried Instantly for 6 months and got nowhere — the setup alone took weeks. Switched to Coldflows and had warm leads in my inbox within 3 weeks. Genuinely hands-off.

"
47 warm leads in our first full month. We closed 4 of them — that's $38K in new revenue from a $2,500 spend. We've now been on it for 5 months and it keeps getting better.

FAQ
Questions
What happens after I purchase?+
We immediately provision your system — purchase domains, create mailboxes, configure DNS, start warmup. Dashboard login within minutes. Warmup takes ~14 days, then outreach begins automatically.
Do I need to write any email copy?+
No. Our AI generates all copy based on your service and target market. It A/B tests variations and promotes winners automatically.
Where do the leads come from?+
We source leads matching your ICP — industry, company size, job title, location. Fresh contacts delivered into your campaigns.
Why does warmup take 14 days?+
Email providers need to see your mailboxes are legitimate. Skipping warmup means spam. We build reputation properly — 95%+ inbox placement.
What results can I expect?+
At full capacity, 2-4% reply rates — 40-80+ warm leads per month on Growth. The AI improves over time. 3+ month clients see significantly higher performance.
Can I connect via API?+
Yes. Every account includes API access. Read campaign data, metrics, leads. Growth and Scale include write access plus webhooks.
Is there a contract?+
No contracts. Cancel anytime. We recommend 3 months to see the full benefit of the self-learning AI.
