My business has been working with Scott and Liam over at Harper for over a year now and can really boast about how good they are. They have had a significant impact on our sales and really helped us top the funnel up — the ROI currently is roughly 11x spend.
Read their case study M Matthew Harrison Google Review
We've had a great experience with Harper. The team helped us launch our outbound sales process which has ultimately allowed us to reach lots of new opportunities. It resulted in our best ever sales month in October, with Harper's leads being directly responsible.

I've got nothing but great things to say about Scott and the team at Harper. As both a partner and a supplier, they're exactly the kind of people you want in your corner if you're serious about growth.
D David Gavin Google Review
We've had a great experience working with Harper. Scott, Liam and the team have been fantastic throughout. After a year of working together, we've seen a consistently strong conversion rate from the leads they generate.
M Megan Emerson Google Review
An incredible agency with great people behind it! I've worked with Scott, Liam and Georgia for over a year now and they really know their stuff. Very confident in saying Harper is one of the best outbound sales agencies around.
J Joe Harulow Google Review
We've really valued partnering up with Harper. Clear communication, honest advice and a human approach to generating leads for our business. They feel like an extension of the team, not just an external agency.
Read their case study M Matthew McHugh Google Review
We've been using Harper for eight months now, and it's had a significant impact on our sales. It has reduced sales admin and allowed my team to focus on client conversations rather than lead generation, which is now automated.
Read their case study G Gavin Bridge Google Review
I run a marketing agency based in Manchester called Red C, and we've used Harper Agency for almost a year now and would highly recommend them. They drive good leads through to the business, and they do it with a proactive and diligent approach.
Read their case study S Steve White Google Review
Harper have played a key role in helping us launch our outbound sales process, providing structure, direction and high-quality prospects from the outset. Georgia was lovely and helped answer any questions we had. Can't wait to see where this can go this year!

Our workflow
Your campaign timeline
From kickoff to a compounding pipeline — exactly what the first six months with Harper look like.
Day 1
Onboarding & discovery call. Kick off with an in-depth session led by our founders — sharing your product, audience and USP while we craft a tailored campaign plan and set you up with the lead portal.
Weeks 1–2
Campaign build & infrastructure. We set up lookalike domains and warm your mailboxes across two weeks to build trust with email providers, so your mail lands in the inbox. Your prospect list is built and messaging signed off.
Weeks 3–4
Replies land daily. Outreach goes live, subject lines are tested, and qualified conversations start arriving in one shared inbox.
Month 2
First full month of outreach. Now it is time for full-scale outreach — sending 20,000+ emails to 10,000 unique prospects. You receive a monthly sales review and a PDF report covering stats, notable wins and ROI insights.
Months 3–6
Optimisation & retargeting. We retarget prospects who have not responded, push for more calls, review ROI on monthly review calls, and explore scaling into new markets, industries or services.
Month 6+
Growth partnership. Over 60,000 prospects have now seen your offer. You are in a position to scale campaigns into new industries and regions, and to launch cross-channel strategies that drive more leads.

Everything people usually ask before starting. Anything missing — just ask us on the call.
We define a lead as a prospect who matches your Ideal Customer Profile (ICP) and has expressed positive interest in starting a conversation or booking a meeting.
Yes, we are fully GDPR compliant. We only process data on the basis of Legitimate Interest and ensure all prospect data is handled securely and transparently.
Warm-up is the process of gradually increasing the volume of emails sent from a new domain. This builds a positive reputation with ISPs to ensure your emails land in the primary inbox, not spam.
As soon as a prospect replies positively you get an email notification, and the lead is issued to a Google Sheet. You reply to them from the Harper platform.

Most campaigns launch within 5 days. While results vary by industry, clients typically see their first qualified leads start trickling in during the second or third week of active outreach.
You choose the term: 12 months, or six months at 10% more a month. The first month is often about testing and data gathering, while the months after are where optimisation and scaling occur.

Absolutely. We operate with an agile mindset. If you want to pivot to a new vertical or change your offer, we can adjust the targeting and messaging scripts accordingly.
For LinkedIn outreach campaigns we use secure, cloud-based access that mimics human behaviour to keep your account safe while we manage connections and messaging.
Yes. You can pause at any time, with one week's notice before your next payment is due. A £200 monthly fee applies while your campaign is paused.
