Messaging angles that work
These are the 3 approaches that consistently get replies in this vertical. Pick the one that fits your prospect best.
1. White-label pitch
Offer outbound as a new service line. You handle the ops, they get the meetings.
Why it works: Agencies always want new revenue streams. Outbound has 70%+ margins when white-labeled.
2. Competitor comparison
"3 of your competitors already offer outbound. Here's the playbook they use."
Why it works: FOMO + concrete proof. Nobody wants to be the agency that doesn't offer what competitors do.
3. Client results angle
Lead with a specific result: "We helped [agency] book 18 meetings/mo for their SaaS clients."
Why it works: Agencies sell results. Show them the result, they'll figure out how to sell it.

White-label intro
Score: 91/100
Subject: Your clients' outbound
Hi {{firstName}},
I run Overloop. We work with agencies like {{company}} who want to add outbound as a service for their clients.
The model: you white-label our platform, charge your clients 3-4x what you pay us, and we handle the infrastructure.
Three of your competitors already do this. Happy to share the playbook.

Revenue angle
Score: 88/100
Subject: New revenue stream for {{company}}
Hi {{firstName}},
Most agencies I talk to are stuck at the same revenue ceiling: retainers + project work. Adding outbound as a service changes the math.
Our agency partners charge $2,500-4,000/mo per client for outbound. Their cost: $800/mo. That's 70% margin on a recurring service.
Want me to walk through how it works?

Case study
Score: 89/100
Subject: How [Agency X] added $40K MRR
Hi {{firstName}},
A 15-person agency like {{company}} added $40K in monthly recurring revenue last quarter by offering cold email to their existing clients.
They didn't hire anyone. They white-labeled our platform, created 3 service tiers, and upsold their current book of business.
6 clients signed in the first month.
Worth 15 min to see if this fits {{company}}?

When they push back
The most common objections in this vertical and exactly what to say.
"We already do outbound internally"
Ask: how many meetings per client per month? Most agencies doing it internally manage 3-5. With a dedicated platform, their clients get 15-20. It's not about doing outbound -- it's about doing it at scale.
"Our clients wouldn't pay for outbound"
Reframe: your clients are already paying for leads through ads, SEO, events. Outbound is just another channel -- and it's the only one with predictable unit economics. Start with one client as a pilot.
"We don't have the expertise"
That's the point of white-labeling. You don't need to be an outbound expert. We handle the infrastructure, deliverability, and optimization. Your team focuses on the client relationship and messaging.
