Case Study — Email Marketing

Building a revenue engine from zero with email

A Corporate Catering Company

£36 ROI per £1 spent

The Challenge

This corporate catering company had built a decent business through word of mouth, but growth had plateaued. They had no email list, no digital lead capture, and no system for encouraging repeat bookings. Every new client required starting from scratch.

Their repeat booking rate sat at just 8% — meaning 92% of clients used them once and never returned, despite consistently high satisfaction scores. The business was leaving enormous lifetime value on the table.

What We Did

  • Lead magnet strategy:Created three downloadable resources — a “Corporate Event Catering Checklist,” a seasonal menu preview, and a budget calculator — gated behind email capture forms on the website.
  • Website form optimisation: Added email capture at five key touchpoints across the website, including exit-intent pop-ups, inline forms on the blog, and a footer signup bar.
  • Welcome sequence: Built a five-email automated welcome series introducing the brand, showcasing past events, and offering a 10% first-booking discount.
  • Post-event follow-up: Automated a post-event sequence requesting feedback, offering a rebooking incentive, and asking for referrals.
  • Seasonal campaigns:Launched monthly campaigns around key corporate dates — Christmas parties, summer events, team-building days — with early-bird pricing.

The Results

In eight months, the email list grew from zero to 2,400 subscribers. Email marketing now generates £36 in revenue for every £1 spent — making it their highest-ROI channel by far. The repeat booking rate jumped from 8% to 28%, transforming one-off clients into loyal, recurring customers.

“We never thought email would be our biggest revenue driver, but the numbers don't lie. The automated sequences Byter built mean we're nurturing leads and rebooking clients without lifting a finger. It's completely changed how we think about marketing.”
