CURRENTLY ACCEPTING 2 NEW CLIENTS FOR Q3 2026

Email is the only channel where your brand speaks directly, without algorithm interference, to someone who chose to hear from you.

WHY LETTERBOX MEDIA

Most agencies spend it on discount codes and abandoned-cart nudges.

We don't. We treat every email programme as a body of work — something that accumulates meaning over time, that sounds like you, that customers actually look forward to opening.

That's why we keep our roster small. It's not a constraint — it's the product.

A small portfolio, built with care.

The StoryFlow Method

01 LISTEN

Before we write a word, we learn your brand's voice, your customer's psychology, and the story your email programme needs to tell.

02 MAP

We design the full customer lifecycle — every touchpoint, every transition, every moment where a well-placed email earns trust or loses it.

03 CRAFT

We write, design, and build your email programme — flows, campaigns, and strategy — as a unified body of work. Everything sounds like you.

04 REFINE

We monitor, test, and evolve the programme each month, with performance reporting that connects to revenue, not vanity metrics.

We work with brands that:

— Are generating revenue but know their emails are underperforming

— Care about how they sound, not just what they sell

— Want a long-term partner who thinks in brand-building terms, not just open rates

— Have patience for work done properly, and expect it to create a lasting impact

And we're probably not the right fit if you need 50 emails next week or want to run weekly discount blasts.

"The flows have been incredibly successful. I cannot recommend Letterbox Media highly enough."

Kelly B., Founder

"They helped us with brand messaging, graphic assets, and their copy was much better than ours. I thought at first it would be just technical advice — it was far more."
