Email and SMS for ecommerce brands

The Revenue Channel Nobody Can Take Off You

We build and run email and SMS as a real revenue line, not a newsletter. Flows, campaigns, capture and deliverability, written and sent by us every week.

On our own stores, flows and campaigns run around a third of total revenue. That is money that arrives whether or not an ad account is live, whether or not CPMs doubled overnight, and it is the first thing we build when we take a brand on. Most stores are running the three default Shopify emails and calling it retention.

Live flow revenue on one of our own stores. Account names redacted, because we do not publish which brands we run.

The proof is in the pudding. Here is what owners say.

Real owners, real names, real builds. We do not invent testimonials and we do not buy stock faces.

★★★★★

Cooper and the team rebuilt our platform end to end. Fast, no hand holding needed, and it does exactly what we asked for.

Owen
Founder, 8WTC
★★★★★

They redesigned our whole store. It finally looks like the brand we wanted and the layout actually pushes people to buy.

Kenan
Founder, E-Motors
★★★★★

Working with Cooper is the easiest partnership I have. He builds it, it converts, we scale it. No agency nonsense.

Why most stores leak money here

Four reasons your email is making a fraction of what it should.

None of these are exotic. They are just boring, and boring is exactly what agencies skip when they would rather talk about creative.

1

You are renting every dollar of revenue

When paid is the only channel, one restriction, one CPM spike or one bad week takes the whole business down with it. Most stores doing good numbers have almost no owned revenue and find that out on the worst possible day.

What we doEmail gets built as its own revenue line from week one, so the business keeps earning while the ad accounts are being fixed.
2

Your flows are still the defaults

Three generic emails on a timer, a discount stacked in all of them, no segmentation and no reason to open. The abandoned checkout fires once, browse abandon does not exist, and nobody is being asked to reorder when their product actually runs out.

What we doWe build the full set properly: welcome, abandoned checkout, browse abandon, post purchase, reorder window, winback, back in stock. Each one written for where that person actually is, with one job per email.
3

Nobody is capturing the 97 percent

Around 97 of every 100 first time visitors leave without buying. If the popup is weak, mistimed or missing, you paid for all of that traffic and kept none of it. Then every new order has to be bought again at full price.

What we doCapture gets rebuilt: popup offer and timing tested, teaser instead of a wall, mobile handled separately, plus SMS consent where it is worth having. List growth becomes a number we report on.
4

The calendar is one Black Friday blast

Sending everything to everyone a few times a year trains Gmail to bury you. Opens fall, the domain reputation goes with them, and then even the flows that were working stop landing in the inbox.

What we doA real campaign calendar on a 75/20/5 split, segmented by engagement, with sunset rules and unengaged suppression so deliverability goes up while you send more, not less.
What we actually run

Three pieces. We write them, we build them and we press send.

You give us access and we operate. There is no strategy deck at the end of the month, there is revenue attributed to email and the sends that produced it.

Pillar 01

Flows

The money that arrives while you sleep. Built once, written properly, then improved every month against real numbers rather than opinions.

  • Welcome series that leads with the offer for ready buyers and educates underneath for the hesitant ones
  • Abandoned checkout and abandoned cart written to answer the two objections people actually stall on, not just to shout a code
  • Browse abandon, the flow almost nobody has running, catching intent before the cart even exists
  • Post purchase that confirms the decision, reduces refunds and sets up the second order
  • Reorder window timed to how long your product actually lasts, which is the highest intent email you will ever send
  • Back in stock and price drop, plus winback tiers for 90, 180 and 365 day lapsed buyers
  • Flow filters, splits and suppression set correctly so people stop getting three emails in an hour
Flows are the fastest thing we can do for you. The traffic is already arriving, so the revenue starts the week they go live.

Pillar 02

Campaigns

The weekly heartbeat. Written and sent by us on a calendar you can see a month ahead, segmented so your best buyers and your tyre kickers never get the same email.

  • A planned calendar on a 75 percent value, 20 percent soft sell, 5 percent hard offer split
  • Segment by engagement window, purchase history and product interest instead of sending to everyone
  • Launches, restocks, bundles, education, founder emails and proof drops, not just discounts
  • Plain text and designed HTML used deliberately, because they do different jobs
  • SMS layered in where it earns its place, for restocks, drops and cart recovery
  • Peak season planned in advance: a real Black Friday and Cyber Monday sequence, not one blast
You approve the calendar, we write and send everything on it. Nothing gets handed back to you as a template to finish.

Pillar 03

Capture, deliverability and testing

The unglamorous half that decides whether any of the above lands. Most of the lift we find in an account is here.

  • Popup and sign up form rebuilt: offer, timing, teaser, mobile variant, SMS consent
  • Lists and segments structured properly so the data can actually be used
  • Deliverability work: domain authentication, warm up, sunset rules, unengaged suppression
  • A real testing plan on subject lines, offers and send times, one variable at a time
  • Design system in Figma so every send looks like the brand and renders on mobile
  • Straight reporting: revenue from email, flow versus campaign split, list growth, cost per email dollar
We diagnose by walking the funnel backwards. Low opens is a subject line problem, good opens with no clicks is an offer problem, and they get fixed differently.

The receipt

Email runs around a third of revenue on the stores we own.

Not a client account we inherited at scale. Our own brands, our own money, the same flows and the same calendar we would build for you.

Live brands we operate right now

We will open the accounts on the call and show you the real dashboards. Numbers on a website are easy, so we do not expect you to take ours on faith.

Why Owners Trust Collar

Every agency says they are different. Here is ours in plain English so you can hold us to it.

01

We Own The Brands We Learned On

We are not an agency guessing. We run 5+ live ecommerce brands and we spend our own money on them daily, so the playbook we sell you is the one we are already using.

02

We Send, You Do Not

You are not buying a strategy document or a template pack. We write the copy, build the emails, set the segments and press send every week.

03

Owned Revenue Is The Point

Paid can be taken off you overnight. Email cannot. We build the channel that keeps the business alive on your worst month, not just your best one.

04

Deliverability Is Treated As Real Work

Most of the money we find is in capture, segmentation and inbox placement. It is boring, it is unsexy, and it is where the lift is.

05

No Lock In Contracts

If it works and it is priced fairly, why would we need to trap you? Happy clients stay. That is the whole strategy.

06

You See The Number, Not A Deck

Revenue from email, flow versus campaign split, list growth and what we sent. No 40 page report nobody reads.

Cooper Sipos
Cooper SiposFounder of Collar Agency

I Spend My Own Money On This Every Day.

I'm Cooper. I do not run an agency that learned marketing by reading about it. I own and operate 5+ live ecommerce brands with a team of 10+, and every one of them lives or dies on the same channels I am offering to run for you.

Before any of this I was on the tools: building houses as a carpenter, then running electrical through homes and commercial buildings across Sydney. Then I sold real estate at TRG Sydney, circa $100,000,000 AUD sold in my first year, including a record $20 million penthouse. That job taught me the only thing that matters in marketing: nobody buys the product, they buy trust in whoever is selling it.

Then I spent over five years grinding at ecommerce before it clicked. When it clicked it clicked hard: one store went from $5K to $150K in a single month, then past $500,000 USD a month. One brand did $2.3M in 45 days. I post the real numbers publicly, because talk is cheap and screenshots are not.

So when you hire us you are not buying a strategist's opinion. You are buying what we already do with our own capital, on our own brands, every single day.

I do not sell marketing that looks clever. I sell marketing that puts money in the account, and it happens to look good.

The receipts - tap the pile

Questions brand owners actually ask

How fast does email make money?
Faster than any other channel we run, because the traffic is already there. Flows can be live inside two weeks and they start earning the week they switch on. Campaigns compound from there as the list grows and the segments get cleaner.
What percentage of revenue should email be?
On a healthy ecommerce brand, somewhere around a quarter to a third of total revenue, with flows doing the heavy lifting inside that. If you are in single digits there is money sitting on the table right now and the audit will show you where.
Klaviyo or Omnisend, and do I have to switch?
We work in both and we will tell you honestly if your current platform is fine. Most of the time it is, and switching is a distraction from the work that actually makes money. If you genuinely need to move we handle the migration.
Do you write the emails or do I?
We write them. Copy, subject lines, offer, design and the send. You get a calendar to approve, not a pile of homework.
Will more emails get me marked as spam?
Not if the sending is segmented. The brands that get buried are the ones blasting a single list of everyone they ever met. We suppress unengaged, sunset the dead weight and send more to the people who actually open, which raises placement rather than wrecking it.
What do you need from me to start?
Platform and store access, your product and shipping facts, and honesty about what has already been tried. We do the rest.
Next step

Send us your store. We will tell you what your email is leaving behind.

A free audit of your flows, your capture and your deliverability, with the three fixes we would make first and what each one is worth. No pitch deck and no retainer talk until you have had it.

Get your free email audit

We take a limited number of retention clients at a time, because writing and sending every week does not scale by hiring juniors.

Your Store. Your Flows. A Free Audit.

Give us your store and your email platform. We go through your flows, your popup, your segments and your last 30 days of sends, then tell you exactly where the revenue is leaking out.

You get the three fixes we would make first, in order, with what we think each one is worth. We record it and send it to you. If you want us to build it, we build it. If not, you keep the plan and owe us nothing.

Where should we send your audit?
