Book a Call
For B2B Businesses

Qualified sales calls booked on your calendar. Pay only for the ones we book.

A complete done-for-you cold email system running for your business, handled end-to-end. We build the lists, write the copy, manage deliverability, qualify replies, and book the calls. You take the meetings and close. Pay only for calls that book.

The Problem

Your pipeline runs on hope.

Most businesses can’t predict how many qualified conversations they’ll have next month. That uncertainty is the whole problem.

01

Feast or famine pipeline

Some months the deals come in. Other months go quiet and you can’t explain why. Referrals, networking, word of mouth, whatever’s bringing deals in right now, none of it is something you can turn up when you need it. You’re one quiet month away from a cash flow problem.

02

Your closers are starved

Whether that’s a sales team on salary or you doing the selling yourself, there aren’t enough qualified conversations coming in to fill the capacity you already built. Every day a closer sits idle or a founder spends hours prospecting instead of closing, that’s money burning.

03

Nothing else is fast and controllable

Content takes months to compound. Ads are a gamble and CAC keeps climbing. SEO is a long game. Referrals you can’t manufacture. There’s no acquisition channel you can switch on, scale up, and know what you’re going to get.

There's a better way

Stop chasing pipeline. Start taking calls that are already booked.

Why Blackthorn

What makes us different?

Most cold email agencies charge a retainer to send emails and hand you the replies. We handle the entire chain and only get paid when a qualified call lands on your calendar.

Pay per booked call

Most agencies want a retainer for potential. We bill on booked qualified calls, so if we don’t put prospects on your calendar, we don’t get paid. The risk sits on our side, not yours.

Done for you, end to end

Most cold email agencies send emails and dump replies in your inbox for you to sort through. We handle the full chain from list building and copy through deliverability, reply qualification, and call booking. You take the meetings and close.

Qualified calls only

Every reply gets qualified against your ideal client profile before anyone books a call. We look at budget, authority, fit, and timing so tire kickers never make it onto your calendar and your closers never waste time on someone who wasn’t going to buy.

Month to month, keep everything

There are no long-term contracts and no lock-in of any kind. If we part ways, you keep the lists, the copy, the infrastructure, and everything else we built for you. It’s month to month, purely pay per call, and you’re never stuck.

Comparison

Our Process

How we fill your calendar

Here’s how it works from start to finish. Every step below is handled by us, from understanding your offer to booking qualified calls on your calendar.

01
Week 1

Strategy & ICP

We define your ideal client profile, map your target market, and build the foundation for the entire campaign. You tell us about your offer and we translate it into a targeting strategy.

02
Weeks 1 to 2

List & Infrastructure

We build and verify your lead list, set up sending domains and inboxes, run warmup, and configure the sending infrastructure. Everything is under our accounts and managed by us.

03
Weeks 2 to 4

Copy & Launch

We write your cold email copy and follow-up sequences, then launch sending at controlled volume. Inbox warmup takes two to four weeks before volume sending stabilizes.

04
Ongoing

Replies & Qualification

We monitor inboxes, handle replies, qualify leads against your ICP, and separate interested buyers from tire-kickers. Only prospects who match your criteria and have the actual problem move forward.

05
Ongoing

Booking & Optimization

Qualified prospects get booked directly onto your calendar. We A/B test subject lines and copy, refine the list based on reply data, and send weekly performance reports. Calls land within the first week of sending.

Questions

Frequently asked questions

Everything you need to know before booking a call.

01

How fast will I see calls on my calendar?

Inbox warmup takes two to four weeks before volume sending stabilizes. Once sending begins at full volume, you can expect calls to start landing on your calendar within the first week. The full picture, consistent call volume with optimized copy and targeting, typically takes 45 to 60 days from onboarding. We don't promise overnight results, we build a system that compounds.

02

How much does it cost?

A flat monthly tech fee covers your sending infrastructure, domains, inboxes, software, and deliverability management. On top of that, you pay per qualified call that books on your calendar. No retainer for promises, no hidden fees. Exact pricing depends on your market and deal size, and we'll walk through the math on the call to make sure the economics work for your business before you commit.

03

What happens if a booked call no-shows?

We bill on booked qualified calls, not on show-ups. A no-show doesn't reduce your invoice. Here's why: if we billed on show-ups, we'd have to price in your sales team's performance and raise the per-call rate to cover no-shows we can't control. Show rate is driven by your pre-call follow-up, scheduling process, and offer strength. We handle pre-call email confirmations, but attending the call is your side of the equation.

04

Do I need to provide anything?

Yes, but not much. Within seven days of onboarding we need your ICP, offer details, any testimonials or case studies, calendar access, and any existing messaging you want us to reference. After that, we handle everything. You never touch a sending tool, never manage an inbox, never worry about deliverability. Your only ongoing job is showing up to the calls we book and closing them.

05

What counts as a qualified call?

A prospect who matches your ideal client profile (industry, company size, revenue range, location), has the actual problem your offer solves (not just “interested to learn more”), indicates they have budget or can afford your solution, has decision-making power, and books a specific time slot on your calendar. Attending the call is not part of qualification. If a prospect meets all five criteria and books, the call is qualified and payment is due.

06

What if I want to stop working with you?

Either party can terminate with written notice, effective at the end of the current billing month. You pay for all qualified calls delivered through that date, no prorating, no mid-month cutoffs. Month to month, no minimum commitment. When you leave, you keep every deliverable: email copy, follow-up sequences, lead lists, and campaign assets. Sending infrastructure stays under our accounts unless otherwise agreed in writing.
