Inboxxia

Inboxxia is a boutique growth agency that has carved out a distinct niche in the B2B appointment-setting space. Founded by Hugh and Teddy, the agency combines a PhD-level understanding of behavioral economics with hands-on operational experience. Based in Manchester, England, Inboxxia positions itself as a results-driven partner rather than a volume-based lead generation mill. Their core promise is simple: they focus on return on investment, not just activity metrics.

What sets Inboxxia apart is the direct involvement of its founders in strategy and campaign management. Hugh brings expertise in business development and management, while Teddy applies his background in behavioral economics to craft messaging that engages prospects and drives action. This combination ensures that every campaign is built on a foundation of tested psychological principles, not guesswork. The agency has set over 5,000 appointments and maintains an average 10x ROI for clients, with some reporting as high as 19x.

Inboxxia's service offering covers the full outbound sales cycle: from outreach system build and list building to lead nurture, CRM management, and appointment setting. They also offer A/B testing, campaign strategy, offer development, and expertly written messaging. This end-to-end approach means clients can hand over the entire lead generation process and focus on closing deals. The agency works primarily through cold email outreach, but their methodology is adaptable to multi-channel approaches when needed.

Pricing is project-based and transparent. Packages start at £4,000 for 10 qualified meetings (£400 per meeting), £7,000 for 20 meetings (£350 per meeting), and £9,000 for 30 meetings (£300 per meeting). This tiered structure rewards higher commitment with a lower per-meeting cost, making it attractive for companies with consistent pipeline needs. Setup fees are excluded, so clients should factor that into their budget. Compared to many agencies that charge monthly retainers without guaranteed outcomes, Inboxxia's model is refreshingly output-focused.

Client feedback is overwhelmingly positive. Customers consistently highlight the agency's proactive approach, adaptability, and ability to deliver high-quality leads in niche markets. One client noted that Inboxxia "outperformed them by some stretch" compared to other business development partners. Another praised the team as "incredibly industrious" and reported closing a good number of leads. The only recurring critique is that reporting could be more detailed, particularly around tracking progress and re-engaging past leads. This is a minor gap in an otherwise strong service.

Inboxxia is best suited for B2B companies that value quality over quantity and want a hands-on, founder-led agency. Their behavioral economics-driven messaging works particularly well for complex or high-ticket offerings where engaging C-suite decision-makers is critical. If you need a reliable partner to fill your pipeline with qualified meetings and are willing to invest in a premium service, Inboxxia is a strong contender. For companies that require granular reporting or have very high volume needs, the agency may feel less transparent or scalable. Overall, Inboxxia delivers on its core promise: appointment setting with a genuine focus on ROI.
