EMAIL MARKETING AGENCY FOR ECOMMERCE BRANDS


Email marketing that gives customers a reason to come back.


You worked hard to get the customer. Email marketing helps make sure that isn't where the relationship ends.

Letterbox helps founder-led, family-owned and women-owned ecommerce brands create strategic email marketing that keeps customers engaged, strengthens repeat purchases and makes more of the audience you've already worked hard to build.

SOUND FAMILIAR?


You're emailing when you remember.

Campaigns happen reactively rather than as part of a strategy designed around your customers and commercial goals.


Everyone gets the same email.

Your newest customer and someone who hasn't purchased in a year probably shouldn't be having exactly the same conversation with your brand.


Your list isn't doing enough.

You've built an audience of people who have already shown interest in your business, but you're not making the most of the opportunity to keep them engaged.

What We Do

More than filling up a campaign calendar.


We don't believe good email marketing means sending more emails for the sake of it.


We look at what your business is trying to achieve, where the opportunities are and what your customers actually need to hear from you.


Then we build the strategy around that.


Email Strategy & Planning

A clearer plan for what you're sending, why you're sending it and how email supports your wider business goals.


Campaign Creation

Strategic campaigns that support promotions, launches, products and everything happening inside your business.


Copy & Creative Direction

Emails that sound like your brand — and give people a reason to actually care about what's in their inbox.


Segmentation & Personalisation

More relevant communication based on customer behaviour, engagement and purchase history.


Testing & Optimisation

We keep learning from what's working, what's not and where there's an opportunity to improve.

MARKETING FOR BRANDS BUILT DIFFERENTLY

You didn't build your business from a template. We won't market it like one.


Letterbox Media works with founder-led, family-owned and women-owned ecommerce brands that want their marketing to feel as considered as the business they've built.


That means understanding the people behind the brand, not just looking at a dashboard and sending whatever worked for someone else.


We bring the strategy and expertise you'd expect from a serious email marketing agency — without turning your marketing into something generic, corporate and completely forgettable.
