Still wondering how we can help? Here’s how.
We use Cold Email as a scalable engine for top-of-funnel pipeline growth. But it only works if you nail three things:
Getting into the primary inbox
Hitting the right stakeholder at the right company
Making the prospect want to reply
Inbox Delivery Engineering
We don’t “blast” emails. We architect your sending infrastructure, warm up and rotate domains, manage inbox pools, and constantly monitor sender reputation—so your emails reliably land in the primary inbox where prospects actually see them.
Laser-Targeted Prospecting
No more spray-and-pray lists. We identify high-intent prospects using buyer signals, job moves, tech stack data, and behavior—so every outreach goes to the right decision-maker, at the right moment.
Copy that Converts
We don’t churn out templates—we craft emails people want to open and respond to. Messaging is tailored, relevant, and anchored in your value proposition, so every reply is driven by real intent and real business outcomes.
How does Mumbo Leads work?
Generate Business Development calls and deals with your exact ICP in 4 easy steps.
Call → Proposal → Deal?
We hop on a quick call, align on goals, send you a proposal, and lock things in with a simple MSA.
Kickoff Call → Setup Phase
We run a deep-dive strategy call, then spend 30 days building your infrastructure: domains, lists, copy, and systems.
Campaign Launch
One month after kickoff, your emails go live. We hit the field and start generating real conversations
Optimize → Scale → Repeat
Every week we iterate: better targeting, stronger messaging, higher reply rates... then we scale what works.
