Email Marketing Case Studies

Letterbox Media (Shri and the team) have been brilliant for our email marketing. They moved us across to Klaviyo smoothly, then quickly started delivering better-structured campaigns and flows that genuinely make our small budget go further.
Communication is consistently clear, proactive and friendly, and everything is well organised - we always know what’s happening and why. Highly recommend them if you want email that feels strategic, not just “sent.”

Letterbox Media spent time unpacking my confused and complicated Klayvio setup which involved a very different tech stack and required several custom workarounds. They broke down what they were doing in layman's terms with detailed reports and delivered on time. They even helped me after the job was done. They went above and beyond and offered a very competitive rate. I would recommend it again and again.

I have a social enterprise with very specific needs, it is quite a complex business. Letterbox Media worked with me on our Klaviyo flows. I thought at first that it would be just technical advice for best practice, but it was FAR more. They helped us with brand messaging, graphic assets and their copy was much better than ours! The flows have been incredibly successful for us. I cannot recommend Letterbox Media highly enough and will be doing more projects with them.

We had a great experience working with Shri at Letterbox. She quickly understood our brand and created beautiful, on-brand email templates that were both engaging and easy to use. The process was smooth, professional, and creative from start to finish. Highly recommend!

I highly recommend Letterbox Media! I had been using Klaviyo for a few years, and no matter what new strategies I tried, nothing was driving the growth I wanted. In just the first month of working together, my revenue tripled - and over the past four months, I’ve seen more sales than I did in the entire previous year. Their email designs are exactly what I had been trying to create (and couldn’t), and they have been consistently attentive, strategic, and easy to work with. Partnering with them has been one of the best decisions I’ve made for the business!

Letterbox Media offered an excellent balance between enhancing what we already and making significant changes where required. They made the process easy for us; we gave them ideas and suggestions to which they developed the first draft, which was then refined to the final version. Nothing was too much trouble, and the recommendations from Letterbox Media made the final version far better than we could have hoped for. We are so impressed with their work; we will continue to use their skills to improve our online marketing.
