Main ideas
Acquisition is a system: paid social, varied creative and owned retention flows · Growth is only worth having if it improves margin · Channel mix is a sequencing decision, and owned channels can move demand
Domenick S. shares first-person lessons from EBOOST’s ecommerce growth, including how the business has used Shopify, Amazon, product offers, and customer acquisition.
The posts focus on the choices behind growth: using trial packs to lower the barrier to a first purchase, shifting customer attention toward Amazon while reducing promotions, and changing a popular product from single sachets to a larger tub.
A post about a vendor email that led to a signed deal offers a different angle: how specific research and product knowledge can make outreach stand out.
The distinctive thread is explaining business decisions through customer benefits and commercial tradeoffs.
The SUPER POWDER post links a larger serving format to lower cost per serving for customers and higher revenue per order for the brand.
The Amazon post pairs channel growth with reduced ad dependence and a greater focus on margin.
These brief, concrete accounts give readers specific questions to consider about their own offers, channel mix, and growth measures.
Domenick S. writes about ecommerce growth at supplement brand EBOOST as a series of trade-offs: which offer lowers the barrier to a first purchase, which channel deserves the spend, and which metric reflects profit.
Read more
Two arguments recur: judge new-customer acquisition by cost per acquisition rather than return on ad spend, and count growth only when it improves margin. The posts read as a decision record, not a highlight reel: trial sizes and re-engagement flows to win and keep customers; a deliberate shift in demand from Shopify to Amazon through owned email and SMS; a product format change backed by sales data; and a teardown of a vendor email showing how they judge a pitch aimed at them.
Acquisition is a system: paid social, varied creative and owned retention flows
Domenick S. treats customer acquisition as a chain, not a single channel.
Read more
Meta is the main paid channel for bringing in new customers; Klaviyo and Postscript flows sustain the relationship through re-engagement, value and deals.
Creative varies deliberately because customers respond to different formats.
They prefer cost per acquisition over return on ad spend for growth, while allowing return on ad spend a role in retargeting.
The post credits two years of work with 40,000+ customers on the EBOOST Shopify Plus store. It names SUPER FUEL four-packs and a nine-pack of pre-workout as trial offers, with UGC, influencer and static posts in the creative mix.
The stated test is margin and profitable growth, not revenue volume.
Read more
In the Amazon post, the team pulls back further on promotions to focus on margins, concluding that growth is good but profitable growth is better. The acquisition post makes the same point by prioritising cost per acquisition over return on ad spend.
The Amazon post describes cutting promotions on Shopify, then on Amazon, to protect margin rather than chase volume.
The two posts trace a shift in priorities: promotions first build Shopify, then are throttled in favour of Amazon, before being reduced on Amazon as the focus shifts from channel revenue to margin.
Channel mix is a sequencing decision, and owned channels can move demand
Rather than stick to one storefront, Domenick S. describes redirecting customers between channels through cost-efficient owned media.
Read more
Email and SMS push buyers toward Amazon instead of relying on ad spend or discounts, with a claimed result of a seven-figure Amazon channel where most customers arrive organically. The strategy aims to avoid ad dependency and a price race as well as drive sales.
The post reports that 85% of Amazon customers buy organically after the switch, with the goal of avoiding ad dependency and the Bezos tax.
Shopify was the priority through 2023, supported by Meta ads and promotions. In 2024, spend and attention shifted to Amazon through email and SMS; the latest position is to reduce promotions on both channels.
Offer design is a lever for both customer value and brand margin
Packaging and serving format are growth decisions driven by sales data.
Read more
Trial sizes lower the commitment for a first purchase and feed retention flows; larger formats can lower the customer's cost per serving while raising the brand's margin. Domenick S. presents these changes as wins for both sides, not a trade-off.
SUPER POWDER shifted from single-sachet packets to 40-serving tubs after becoming the top-selling SKU on Amazon and Shopify. The stated reasons were a lower cost per serving for the customer and a higher ring for the business.
A pitch is judged on due diligence and product awareness, not timing
In the one post not about EBOOST's own funnel, Domenick S. breaks a vendor email into its subject line, personalisation, due diligence and product awareness, identifying the specifics that turned a cold message into a signed deal.
Read more
The decisive detail was evidence of real account-level work, not a claim about the product category. They conclude that timing did not matter because the product was a fit: any time works to reach out if the fit is there.
A sender from Storelocators listed exactly how many Tropical Punch POW units were in stock at local stores—a detail Domenick S. says they did not know a store locator could track. The result was a booked demo and a signed contract.
This is the fullest single statement of how Domenick approaches ecommerce growth, and it sets out the vocabulary — trial sizes, CPA over ROAS, flows, UGC — that the other posts assume.

A newcomer who reads only one item should read this one.
A first-person account of two years of customer acquisition at supplement brand EBOOST.
Four levers are named and explained: sample and trial-size packs (a four-pack and a nine-pack of pre-workout) that let shoppers try before committing; Meta as the main paid channel, with Klaviyo and Postscript flows handling re-engagement after the first purchase; a mix of UGC, influencer and static content; and a stated preference for cost per acquisition over return on ad spend.
The post is a tactic list, but each tactic comes with the reason it was chosen, making it a decision record rather than a highlight reel.
For brands planning a campaign
Relevant to a wellness brand weighing trial sizes or rethinking its paid and retention mix. The CPA-over-ROAS position is a specific, arguable claim a brand can test against its own account data before committing to a brief.
Where the Shopify post explains how customers were won, this one explains how the channel mix was deliberately changed.
Read more
It shows that Domenick thinks about sequencing and margins, not just tactics.
Describes a two-year shift: Shopify was prioritised through 2023 with Meta ads and promotions; in 2024, promotions were throttled back and customers were pushed toward Amazon through email and SMS instead of heavy ad spend.
The claimed results: Amazon is now a seven-figure channel, 85% of Amazon customers buy organically, and the current priority is margin rather than volume.
The reasoning is about dependency — avoiding ad reliance and price competition — as much as the sales figure.
For brands planning a campaign
Useful for a brand deciding where to concentrate spend across its own store and a marketplace. The claim that organic Amazon demand can be built by redirecting owned channels is checkable, and the margin framing gives a brand a concrete question to put to this creator.
The shortest item, but the clearest example of a product and packaging decision driven by sales data rather than taste.
Read more
It shows how Domenick talks about offer design in one pass.
Announces that SUPER POWDER, previously sold only in single-sachet packets, is now available in 40-serving tubs.
The stated reason: it was the top-selling SKU on both Amazon and Shopify.
Three outcomes are listed: a lower cost per serving for the customer, a larger serving size, and a higher margin for the brand.
The post presents it as a straightforward win for both sides, with a link to the product page.
For brands planning a campaign
A concrete precedent for a brand considering pack-format changes as a margin and retention lever. It also shows how this creator frames offers — customer value and brand margin in the same breath — a lens likely to inform a campaign brief.
It shows how Domenick reads and judges sales messaging aimed at them, offering a different but complementary kind of evidence about their judgement.
Breaks down a vendor email from a store-locator company into four parts: subject line, personalisation, due diligence and product awareness.
What impressed Domenick was the sender’s precise count of Tropical Punch POW units in stock at local stores — information they did not know a store locator could track.
The outcome was a booked demo and a signed contract.
The post argues that timing did not matter because the product was a fit.
For brands planning a campaign
Useful for a brand planning outreach, partnership or vendor pitching: it names the specifics that separate an ignored message from a signed one. It also reveals an interest in retail and inventory tooling that a brief about store-level or omnichannel execution could draw on.
Domenick S. describes using trial and sampler sizes, from a SUPER FUEL 4-pack to a 9-pack of pre-workout, so customers can try before committing.
Read more
The goal is to let the product sell itself and move trial users toward a favorite product and repeat purchase.
For brands planning a campaign
A wellness brand can test a sampler or trial bundle as an entry offer, then use email or SMS flows to convert trial buyers into repeat purchasers. Measure cost per acquisition and repeat rate, not just first-order return on ad spend.
The account says Meta remains the main paid channel for new-customer acquisition, with Klaviyo and Postscript flows handling re-engagement, value, and deals.

Domenick S. prefers cost per acquisition over return on ad spend for growth, while allowing return on ad spend a role in retargeting.
Meta ads for acquisition; Klaviyo and Postscript for re-engagement; UGC, influencer, and static content for creative variety.
For brands planning a campaign
A brief should connect paid social creative to a retention sequence.
Ask for cost-per-acquisition targets and re-engagement flows, not just top-of-funnel impressions.
A creator partnership can supply UGC and static assets for the system.
A post describes pulling back Shopify promotions in 2024 and using cost-efficient email and SMS to push customers to Amazon.

The claimed result is a seven-figure Amazon channel with 85% organic customers, no ad dependency, and less price discounting. The approach then shifts further toward margin over promotion volume.
For brands planning a campaign
For a DTC wellness brand, this is a playbook for using owned channels to shift demand to Amazon while reducing ad and promo dependency. A campaign can test email- or SMS-led Amazon pushes and track organic mix and margin, not just channel revenue.
A post analyzes a cold email from Storelocators that led to a demo and signed deal.

Domenick S. highlights personalization with name and company, due diligence listing local store inventory counts, product awareness around store-locator inventory tracking, and timing that did not matter when the product fit.
Teardown of subject line, personalization, due diligence, product awareness, and timing.
The post says timing did not matter for this purchase because the product fit the brand.
For brands planning a campaign
Useful for B2B outreach or partnership pitching: show specific account-level research and a product capability the buyer did not know was possible. A brand can ask for this kind of teardown content or use it to shape its own outbound tests.
The acquisition post says content includes UGC, influencers, and static posts, with the claim that every piece hits differently because customers respond differently.
Read more
For brands planning a campaign
A creator campaign should not rely on one format. Include UGC, influencer, and static variations, then test which combination moves cost per acquisition and retention.
Across the Amazon and Shopify discussions, Domenick S. repeatedly returns to margin and profitable growth.
Read more
The Amazon post says growth is good but profitable growth is better, and that the team is pulling back on Amazon promotions to focus on margins. The Shopify acquisition post prioritizes cost per acquisition over return on ad spend for growth.
For brands planning a campaign
Campaign measurement should include contribution margin or profit, not just revenue or return on ad spend. A brand can ask a creator to frame value and retention rather than perpetual discounting.
The posts tie Domenick to one brand they speak about from the inside: EBOOST.
Read more
They describe the brand’s Shopify Plus store, Amazon channel, product sizes, and a vendor the business bought from after a cold email. They don’t specify whether Domenick owns EBOOST, works for it, or works with it as a client; ask for clarification before assessing the relationship.
EBOOST
Disclosed partnership
The posts describe EBOOST as the business Domenick works on, referring to “our EBOOST Shopify Plus store” and “our Amazon customers.”
Read more
They cover how EBOOST acquired more than 40,000 customers in two years through trial sizes, Meta ads, and email and SMS flows, and how the Amazon channel grew to seven figures, with 85% of customers buying organically. The posts don’t specify whether Domenick owns the business, works for it, or works with it as a client; ask for clarification before assessing the relationship.
A post on cold outreach describes an email from Jack at Storelocators that listed how many Tropical Punch POWs were in stock at EBOOST’s local stores.
Read more
Domenick read it, booked a demo, and signed up, making EBOOST a customer of the store-locator service. The post presents Storelocators as a vendor the business adopted, not as a sponsor of Domenick’s content.
Amazon is described as a seven-figure sales channel for EBOOST.
Read more
After pulling back on Shopify promotions, the business directed customers to Amazon through email and SMS. The post reports that 85% of Amazon customers now buy organically rather than through ads.
The posts describe it as the brand’s core channel in 2023, the storefront where trial and sampler sizes are sold, and one of the places the 40-serving SUPER POWDER tub became a top-selling product.
Domenick S. writes from inside a supplement brand's ecommerce operation, so the fastest way into the work is through channel and offer decisions rather than product reviews.
Read more
Start with their posts on Shopify acquisition—trial and sampler sizes, Meta ads, Klaviyo and Postscript flows, and a stated preference for cost per acquisition over return on ad spend—then the Amazon post on moving demand through owned email and SMS.
Their product-format post weighs a serving-size change against both customer cost per serving and brand margin, and the cold-outreach teardown is the most portable piece for anyone who pitches or gets pitched.
Profitability is the recurring lens: which channel, offer, and metric actually improves margin.
For adjacent reading, Vira Sadlak goes deeper into email and retention craft, Ashley Wright into cross-channel attribution and TikTok Shop, and Saijal Jain into DTC performance marketing with inventory-aware media planning.
Both treat ecommerce growth as a channel-attribution problem, not a single-platform play.
Read more
Ashley Wright's posts describe the same complaint Domenick S. raises—every platform claiming credit for one sale—and push toward a single customer profile and checkable attribution. They also explore creator content on TikTok Shop feeding Meta ads and demand spilling over to Amazon, DTC, and retail.
Ashley Wright writes across brands and platforms as an outside observer, focused on attribution models and TikTok Shop's spread into other channels. Domenick S. writes from inside one supplement business, working through its Shopify-to-Amazon sequencing, offer design, and margin calls.
Vira Sadlak's posts cover BFCM flow preparation, Klaviyo universal content blocks, price-drop and back-in-stock flows, and treating email as a long-term relationship channel that builds predictable revenue—the same owned-retention layer Domenick S. describes using Klaviyo and Postscript to re-engage trial buyers.
Vira Sadlak explores email craft in its own right, including holiday flow reviews and post-season retention promotions, and frames the work as an agency practitioner for ecommerce brands generally. Domenick S. treats email and SMS only as steps in a wider acquisition-and-margin argument.
Both examine what performance metrics mean and how marketplace demand interacts with paid media.
Read more
Saijal Jain's posts question default ROAS reporting, describe optimising Google Demand Gen against First Click with an incremental-ROAS validation, and show branded search and marketplace orders rising off DTC spend—the same measurement skepticism Domenick S. applies when preferring cost per acquisition over return on ad spend.
Saijal Jain works on India-based DTC accounts and centres inventory planning, spend ceilings per hero SKU, and festive-season cash flow, unlike Domenick S.'s material. They focus on a US supplement brand's Shopify and Amazon mix and its product-format decisions.
The placement decision turns on scale and audience type.

This is a small, specialist LinkedIn following rather than a broad consumer audience: the account listed for Domenick S. showed 3,060 followers when observed on 9 October 2026.
The four posts target people running ecommerce growth.
“85% of Our Amazon Customers Are Organic” and the EBOOST acquisition post read as operator case studies for brand-side ecommerce, retention, and acquisition teams.
The cold-outreach post is aimed at sales and agency readers; its author says they are connected with “a lot of folks in sales,” a self-described read on their network, not a measured breakdown.
For a DTC wellness campaign, that points to a credibility placement with ecommerce peers, not a paid-reach placement targeting consumer shoppers.
Ask the creator for recent post impressions, followers gained, and a follower breakdown by seniority, job function, and company size—or an audience survey, if available.
Treat consumer reach as unverified until then.

Domenick S.'s four available posts cover running EBOOST's own ecommerce business — trial-size sampling, Meta advertising, email and SMS flows, Amazon channel strategy, a cold-outreach example, and a product format change — rather than accepting outside brands, quoting rates, or working with sponsors.
Read more
They provide no sponsor policy, format list, rate card, or terms. For a DTC wellness brand, ask whether they accept sponsorships and how they would structure a deal; the terms would need to be negotiated from scratch.
Strong fit for an operator-led growth engagement, content collaboration, or advisory test. The posts show experience running the channels a DTC wellness brand would want to improve: Shopify acquisition, email and SMS retention, Amazon channel development, and offer and pack economics. They do not show a large consumer audience or a confirmed sponsorship offer.
Read more
Brief
A DTC wellness brand wants to improve Shopify and Amazon growth, focusing on ecommerce acquisition and retention rather than mass consumer reach.
Reasons
The EBOOST acquisition post lays out a complete acquisition and retention loop: trial and sampler sizes, Meta as the main paid channel, Klaviyo and Postscript flows for re-engagement, and a mix of UGC, influencer, and static creative. It also states a clear preference for cost per acquisition over return on ad spend for growth—a specific, testable position for a wellness brand.
The Amazon post shows channel rebalancing: pulling back Shopify promotions and using cost-efficient email and SMS to build organic Amazon demand. The claims are concrete enough to test against a brand’s own account data: a seven-figure Amazon channel, 85% organic customers, less ad dependency, and a later shift toward margin.
The SUPER POWDER post shows how offer and packaging decisions tie to unit economics. Moving from single sachets to 40-serving tubs is framed as lowering cost per serving for the customer and increasing margin for the brand, directly relevant to trial-to-repeat and subscription decisions.
The cold outreach teardown shows how Domenick judges specific claims, product awareness, and fit. That’s useful if the brand wants help with outbound, partnerships, or vendor selection—or wants a creator who can explain why one message worked and another didn’t.
The audience evidence is a small, specialist LinkedIn following: 3,060 followers observed on 9 October 2026. That supports credibility with ecommerce peers and brand-side operators, not paid reach among consumer shoppers.
The posts describe no partnership or sponsorship offer. Treat any commercial relationship as something to negotiate from scratch, not as a published creator package with known rates or deliverables.
What to commission
If terms are agreed, the most relevant engagement would be an operator-led growth test: a diagnostic and test plan for Shopify acquisition and retention, paired with an Amazon channel push. Ask for a clear baseline, a defined trial or starter offer, a paid-to-owned retention path, and measurement of cost per acquisition, repeat rate, contribution margin, and Amazon organic share. Don’t brief this as a broad consumer awareness campaign without additional reach evidence.
When to choose a specialist
Poor fit based on the posts. They comprise four text posts about running EBOOST’s ecommerce business, while the audience figure is a 3,060-follower LinkedIn account. That is not enough to support a broad consumer reach or video-led endorsement campaign.
Read more
Brief
A national wellness brand wants broad consumer awareness through short-form video and celebrity-style endorsement, measured mainly by reach, impressions, and follower growth.
Reasons
The posts contain no video, podcast, or off-LinkedIn work, so there’s no basis to judge on-camera performance, short-form video skill, or consumer entertainment value.
Audience evidence is limited to a follower count, with no demographics, impression counts, or follower-composition breakdown. A reach-led campaign would need that data before a brand commits meaningful budget.
No sponsorship formats, rates, or published terms are documented. Confirm whether Domenick accepts sponsorships and offers a standard creator package.
The content is written for ecommerce operators and brand-side growth teams, not mass-market shoppers. It explains channel strategy, retention flows, and margin decisions rather than consumer lifestyle or product appeal.
A brand seeking peer credibility with ecommerce operators or strategic input on Shopify and Amazon growth has a different brief. That may fit well; a broad consumer awareness brief does not.
A worked campaign example
Angle
Run a trial-to-repeat and owned-channel Amazon test, with Domenick as an operator or advisor if terms are agreed. Treat the campaign as a documented growth test, not a product endorsement.
Brief
A DTC wellness brand wants to improve Shopify and Amazon growth. It has a Shopify store, an Amazon listing, and a modest email and SMS list, and wants more repeat purchases without becoming dependent on discounts.
Commercial gap
No partnership format, fee, or deliverable is documented. Confirm scope and terms with Domenick before treating this as a booked engagement.
Measurement
Use cost per acquisition, trial-to-repeat rate, contribution margin, Amazon organic share, and promo dependency. Don’t judge the test only by return on ad spend.
Steps
Baseline: collect cost per acquisition, first-order versus repeat rate, email and SMS revenue, Amazon organic share, average discount depth, and contribution margin.
Offer design: choose a sampler, starter bundle, or trial pack. Calculate cost per serving, margin, and the repeat rate needed to break even.
Acquisition: test Meta creative variants using UGC, static assets, and creator or influencer content. Send trial buyers into Klaviyo or Postscript flows for education, replenishment, and win-back.
Amazon push: run email and SMS segments that direct existing customers to Amazon, then measure organic mix, ad spend, and margin rather than revenue alone.
Review: compare results with the baseline after a set period. Decide whether to scale, adjust the offer, or stop the test.
Choose Ashley Wright over Domenick S. when the main blocker is measurement and channel credit rather than offer design or Amazon channel mechanics.
Read more
Ashley's posts focus on platforms taking credit for the same sale, one customer profile across channels, duplicate emails and discounts, checkable attribution models, and Postscript's email launch.
For a DTC wellness brand already running TikTok Shop, Meta, email, and SMS, that is directly useful if the brand cannot tell which channel actually earned a sale or is paying twice for the same customer.
It is also the better fit if the brand is deciding whether TikTok Shop discovery should feed Meta, Amazon, DTC, and retail, or is evaluating Postscript email alongside SMS.
The tradeoff is less direct operating detail on Shopify and Amazon growth than Domenick S. provides.
Ask whether there is a trial-to-repeat offer, sampler economics, Amazon organic mix, or a full acquisition and retention loop.
A brand that needs help designing a starter pack, improving Amazon organic share, or building Klaviyo and Postscript flows may still need their operator playbook or another specialist for those pieces.
Choose Vira Sadlak over Domenick S. when the immediate task is email and SMS retention, especially Black Friday Cyber Monday (BFCM) flow readiness and lifecycle marketing.
Read more
Vira's posts cover reviewing discount-code flows before BFCM, keeping campaigns and flows consistent, using Klaviyo universal content blocks, price-drop and back-in-stock flows, retention promos after BFCM, and treating email as a relationship channel rather than a one-off sales channel. A wellness brand with a list that is not producing predictable repeat revenue, or one that needs a concrete holiday retention plan, would get more directly applicable guidance here than from their broader Shopify and Amazon growth posts.
The tradeoff is narrower scope: email and retention, not paid acquisition, Amazon channel development, offer and pack economics, or cold outreach judgment. A brand that needs a full acquisition-to-retention system or help moving customers to Amazon organically would still need Domenick S. or another operator for the acquisition and marketplace side.
Choose Saijal Jain over Domenick S. when the campaign decision is constrained by inventory, cash flow, or marketplace stock planning.
Read more
Saijal's posts cover media-inventory sync before festive season, calculating a spend ceiling per hero SKU from available units and average selling price, deciding which SKUs deserve media spend, mapping the cash flow waterfall, and planning marketplace inventory alongside D2C.
The Google Demand Gen post adds a first-click measurement setup, a 300-video creative test, budget splits by product and angle, and a marketing mix modeling (MMM) incrementality check.
A DTC wellness brand with festive-season exposure, procurement lead times, or Amazon and Flipkart stock coordination would get a more specific planning frame here than from their posts.
The tradeoff is context and channel mix.
The posts are built around India DTC and marketplace conditions, including Flipkart, COD, rupee budgets, and festive-season timing.
They are also more media-buying and inventory-planning heavy than retention-flow heavy.
A wellness brand outside that context, or one whose main gap is Shopify retention, email and SMS lifecycle flows, or Amazon organic demand, may prefer Domenick S. or a retention specialist.
Four full LinkedIn posts by Domenick S. cover EBOOST's Shopify acquisition, a shift toward Amazon, a product format change, and a cold outreach email teardown.
