ESBConnect

What ESBConnect does

ESBConnect is a London-based, privately-held email marketing services company founded in 2014, operating with a 11-50 employee headcount under co-founders Suzanna Chaplin (CEO, Commercial Director) and Peter Chaplin, alongside COO Andrew Watson. The company functions as an email advertising and audience marketplace, offering four interconnected core products: Email Acquisitions (subscriber list building), Subscriber Growth (audience expansion), Email Retargeting (re-engagement campaigns beyond CRM), and Email-Based Ad Audiences (creating paid media audiences from email data). Its underlying technology centers on email marketing automation integrated with CRM platforms, with partnerships extending its capability — MirrorMail for email delivery infrastructure and Mouseprice for homemover audience data access. The business model is B2B sales-led, targeting enterprise and mid-market brands across retail/fashion (Secret Sales, Luxury Fashion Brand), automotive/membership (The AA), supermarkets, and utilities, finance, and home improvement verticals. Pricing is quote-based and not publicly disclosed, with revenue appearing to flow through recurring service contracts. The company's competitive thesis rests on positioning owned email audiences as superior to rented social media audiences on ROI and conversion, evidenced by documented case studies including Secret Sales' 1,000 new customers in one month from email retargeting. ESBConnect has disclosed minimal external funding ($353,943 in April 2016) and operates without disclosed institutional backing, while maintaining active marketing through content, industry events (Mad//fest London 2026), and direct enterprise sales engagement.

Broad incumbents
