One-time payment · No monthly retainer · Yours to keep
A 5x ROI within 60 days, or we beat your current setup by 20%. Miss both and you don't pay, and we hand you an extra $1,000 for wasting your time.*
We're an email and SMS agency for e-commerce brands. We've turned unengaged subscribers, warm leads, and forgotten customers into over $100M in recovered revenue that would have otherwise gone down the drain.








Four files pulled straight from the archive. Open any of them for the full breakdown: the goals, the work, the emails, and the numbers that moved.
No flows, no retention system, nothing set up. We built the whole infrastructure, and total revenue grew 22% in the same window.
Open the Case File →Took over another agency's minimal setup, beat their flows by 73%, and total revenue rose 32% over the period.
Open the Case File →Rebuilt pre-purchase, built post-purchase from nothing, beat the old setup by more than 100%, and revenue climbed 16%.
Open the Case File →Full infrastructure plus an SMS launch for a 20-year fitness giant. Previous setup beaten by 47%; revenue up 15%.
Open the Case File →Subscribers go quiet. Flows go stale. Campaigns turn into "10% off" on repeat until people stop opening out of self-defense.
And here's the uncomfortable part: prettier emails won't fix it. Design and copy have been commoditized. Templates are cheap, AI writes passable copy, and every agency portfolio looks the same. The real money moved upstream, into strategy and data: who to send to, when, with what offer, and what to do the moment they stop opening.
Which is why the job title matters less than the job. We're an LTV improver. A churn reducer. An MRR increaser. Email and SMS are simply the sharpest tools for it. Ours also happen to look and read better than anyone else's.
Unclaimed revenue is still revenue.
We go get it for you.
Every account runs the same route. Here's what actually gets done, in order.
A full account audit: flows, deliverability, segments, past sends. We find where the revenue died and why.
A revenue map built from your data: who to mail, when, and with what offer. Plus full-on company research: your customers, your competitors, your category. We become an expert in what you sell and who you sell it to.
Pre-purchase and post-purchase: welcome, abandonment, post-purchase, winback. Written, designed, and built in Klaviyo. This is the always-on machine.
First sends go live in days, not months. The flows start firing, the dashboard starts moving, and we tune the system as the numbers climb.
The traffic at the top is yours. Everything below the dashed red line is what Dead Letter strategizes, writes, designs, and ships.
We do one thing, so we're dangerous at it. No "full-funnel" hand-waving, no juniors learning on your account.
Deliverables go live within 1 to 3 days of kickoff. The variable isn't us, it's how fast you get us revisions and approvals. Your list starts working while other agencies are still onboarding.
Weekly reporting and direct Slack access. You always know what shipped, what it made, and what's next.
We set up for a one-time payment, then you decide if you want to keep working with us on a month-to-month engagement. Our retention strategy is results, not long-term contracts that lock you in.
Our flows aren't templates with your logo dropped in. They're custom revenue assets: researched against your customers and competitors, written and designed to your catalog, and built on segmentation that's proven itself across 100+ accounts. They live in your account and keep firing whether we stick around or not. You keep everything, forever.

I'm Riley Strader. I started as an account manager at one of the fastest-growing agencies in the US, then went freelance and built my own roster from scratch. After reaching the top 3% of email and SMS marketing talent platform-wide on Upwork, it was time for the next step: the agency route.
I'm fortunate to have more work than I know what to do with, so Dead Letter was born out of personal demand for my services. I've built a team I trust, and I still keep my hands in every account we take on. When you hire Dead Letter, my name is on the work.
