Mark Mei runs Dahaus Digital, an e-commerce email marketing agency.
In LinkedIn posts, they offer practical advice on retention email: planning campaigns beyond discounts, segmenting subscribers, and tying email decisions to store economics.
Their work is worth following if you want concrete examples of how an e-commerce operator thinks about email.
Mei links email tactics to the realities of running an online store.
They argue that campaign choices should account for margin and customer value, and describe sending launches to the most engaged subscribers before widening the audience.
For list management, they lay out distinct treatment for recent buyers, VIPs, and inactive subscribers; for campaign planning, they explain how a mix of product stories, offers, and seasonal ideas can reduce reliance on last-minute discounts.
These posts make their advice unusually operational: readers can see the decisions and examples behind it, rather than only broad claims about growth.
A post about agency hiring focuses on staffing and delegation rather than email work, showing that their posts also cover how the agency operates.
Mark Mei's posts draw on running ecommerce stores and then an email agency.

Their recurring argument is operational, not motivational: focus on one channel, judge email by the store's P&L, control list health with explicit segmentation and suppression rules, and keep a stocked campaign calendar so a discount is never the only idea left. The priorities show up in concrete structures — who sits on an account, how many quality checks an email clears, and which subscriber type receives which send — and in a staffing rule: people who handle client email should have run stores themselves.
Specialize in one channel instead of bundling several
Mark Mei argues that agencies selling Meta, Google, SMS and email as one package spread their people thin, so Dahaus Digital focuses on email.
Read more
Each account gets a four-person pod: an account manager, a copywriter, a designer and a Klaviyo technician.
Four people work on one inbox instead of fitting client emails around other channel work.
Every email also clears three quality checks.
The post gives a specific reason for human sign-off: AI can make writers faster, but someone who knows ecommerce approves every send. One model update can change output quality overnight, a risk the post says is not worth taking with a client's list.
Plan campaigns so a discount is not the only idea left
Mark Mei argues that brands treat campaigns like a panic button: sales dip, another discount goes out, and the list learns to wait for the next one.
Read more
The stated cause is a lack of planning. The proposed fix is volume backed by a stocked idea library: a minimum of 12 to 15 campaigns a month per client, drawn from a framework and angle library that the agency's account managers also use.
The library holds nearly 100 angles in three groups: 35 evergreen ideas, such as myth busters, product comparisons and how-it's-made stories; 32 offer angles, from BOGO and tiered discounts to a mystery discount; and 31 holiday angles, running to Boxing Day. The post also describes planning the calendar six weeks out and testing send times from 8AM to 6PM EST.
Set list rules by engagement and buyer status, then draw a suppression line
Rather than prescribe a single tactic, Mark Mei sets out rules for who receives what.
Read more
Engaged subscribers get regular sends; recent buyers stay off campaign blasts because the post-purchase flow covers them; one-time buyers get their own sequence toward a second order; VIPs get early access; and unengaged subscribers see only final-hours sales and product drops. The post argues that sending should follow engagement and buying behaviour, including when to stop.
The 16 BFCM rules include a six-month cutoff for anyone with no click or order; a note that suppression stops Klaviyo billing without deleting profiles; DMARC configured on day one; every-other-day frequency rather than weekly; every third email selling nothing; and revenue per send as the score, because opens are vanity.
Mark Mei argues that email decisions should be measured against the same numbers the store runs on — margin, ad spend, lifetime value and fulfillment, all on one P&L.
Read more
They learned to use that lens while running stores. It also applies to acquisition: traffic that leaves without buying or joining the list is spend that never comes back, so a pop-up is judged on conversion, not signups alone.
The post sets a target of 10 to 15% for pop-up conversion, against a stated norm of 1 to 2%.
It also describes sending launches to the most engaged segment first, then widening the audience.
The post cites iOS 14 breaking Facebook's targeting as the reason the email list is the channel nobody can take away, illustrated by a first batch of fidget spinners making $5,000 and the second batch taking all of it back.
The posts state the agency's scale differently: $2M a year in one and $500k a month in two others. No publication dates appear, so ask for dates before comparing the figures or treating them as a growth curve.
Hire people who have run stores, then get out of their way
Mark Mei argues an agency cannot scale past $100k a month by micromanaging people hired to save money.
Read more
Every account manager and copywriter is said to have run an ecommerce store; many came from larger agencies and are paid above the going rate. The post's counter-argument is that cheap hires who cannot make decisions without the founder turn the founder into a bottleneck on every account.
The example is about account service, not a campaign.
A client's point of contact already understands ecommerce and email, so work moves without the owner hovering over every send.
The post frames recruiting spend as cheaper than buying a full-time management job with a few thousand dollars saved on salary.
The posts extend the same staffing argument to account structure: the four-person pod and three quality checks are the mechanisms that let client email run without founder approval on every send.
This is a useful starting point for understanding how Mei links email tactics to store economics.

It shows that their advice considers costs and business risk, rather than treating opens or campaign volume as the goal.
Mark Mei connects email decisions to the economics of running a store.
They say to judge email against margin, treat paid traffic that leaves without buying or joining the list as wasted spend, and send launches to the most engaged segment before widening the audience.
They also describe learning from a failed second batch of fidget spinners after an earlier batch earned $5,000.
The post frames segmentation and testing as ways to manage business risk, not just improve email metrics.
For brands planning a campaign
For a retention brief, start with the brand’s margin and customer-value goals.
Test a launch with the most engaged subscribers, then widen based on results.
Assess pop-ups by whether they capture value from paid visitors, not by signup rate alone.
This example shows how Mei translates retention strategy into operational segmentation and sending practices.

It’s a practical first read for someone deciding whether their approach fits a list-health or peak-season campaign.
This post turns list management into specific audience rules: regular sends go to people engaged in the past 30–90 days; recent buyers are kept off campaign blasts; VIPs get early access; and unengaged subscribers are reserved for major moments.
It also gives a six-month suppression cutoff, recommends setting up a sending domain and DMARC, and calls for measuring revenue per send.
These are presented as operating rules, not universal benchmarks.
For brands planning a campaign
Use the rules as a checklist for a seasonal campaign plan: define engaged, recent-buyer, VIP, and lapsed segments; decide what each receives; and agree on a suppression policy and revenue measure before increasing send volume. Validate the thresholds against the brand’s own list and deliverability data.
This post shows how Mei approaches campaign ideation when a brand needs frequent emails.
Read more
It helps a newcomer judge whether their work goes beyond segmentation into a repeatable planning process.
Mei argues that relying on discounts when sales dip trains customers to wait for the next offer.
They describe planning 12–15 campaigns a month and organizing ideas into evergreen, offer, and holiday angles, including product comparisons, how-it’s-made stories, and tiered discounts.
They also describe planning six weeks ahead and testing send times.
The examples show a planning system intended to create alternatives to another last-minute sale.
For brands planning a campaign
For a retention campaign, map a month of sends across useful product stories, offers, and seasonal moments. Use the mix to avoid making discounts the default, then test angles and send times against the brand’s own revenue and margin goals.
Mark Mei says the agency focuses exclusively on email rather than bundling Meta, Google, SMS, and email.
Read more
Their argument: multi-channel packages spread teams thin.
Each account gets a four-person pod: an account manager, copywriter, designer, and Klaviyo technician.
Every email clears three quality checks, and someone with ecommerce experience signs off on AI-assisted writing.
Email-only delivery model, four-person pod per account, three quality checks per email, and human approval of AI-assisted copy.
For brands planning a campaign
For a DTC brand looking to improve retention email, this points to depth over breadth. Ask how the pod would work on your account, who signs off on sends, and how quality checks work when AI helps draft copy.
Campaign volume, planning, and reusable angle library
Mark Mei says the agency runs a minimum of 12 to 15 campaigns a month for every client.
Read more
Many brands treat campaigns like a panic button: sales dip, a discount goes out, and the list learns to wait for the next one. To avoid that cycle, they use a swipe file based on the agency’s campaign framework, with nearly 100 angles split into evergreen, offer, and holiday categories, a six-week planning calendar, and send-time tests from 8AM to 6PM EST.
Minimum 12–15 campaigns per client per month, a six-week campaign calendar, categorized angle library, and send-time tests.
The only platform threshold named is Klaviyo’s Smart Sending Time at 12,000 active profiles. The same send-time test may behave differently on another email platform.
For brands planning a campaign
If your retention problem is discount dependency or a thin campaign calendar, assess the angle mix and planning cadence. Ask for a sample four-to-six-week calendar, how they balance evergreen, offer, and holiday angles, and how they test send times before Klaviyo unlocks Smart Sending Time.
Segmentation and deliverability discipline for large sends
Mark Mei lists 16 rules used for 30+ eight-figure brands during BFCM.
Read more
They cover who gets regular sends, who gets only big moments, and who gets suppressed.
Engaged profiles receive regular sends; bounced emails are removed; recent buyers are kept off campaign blasts because the post-purchase flow handles them; one-time buyers get a separate sequence toward a second order; VIPs get early access.
Unengaged profiles receive only final-hours sales and product drops.
Lapsed profiles 90+ days go through re-engagement, then a six-month no-click-or-order suppression cutoff.
Suppression does not delete profiles, but stops Klaviyo charges for them.
The sending setup includes a properly configured sending domain, DMARC on day one, every-other-day frequency, every third email selling nothing, revenue per send as the score, and the full list only when it counts.
Segment by engagement and buyer status, run re-engagement before suppression, configure sending domain and DMARC, send every other day, make every third email non-selling, and score by revenue per send.
These rules are for BFCM and large sends; ask how they would be adapted to your list’s health.
For brands planning a campaign
Use this as a retention checklist for a DTC brand: win-back flows, VIP treatment, one-time-buyer sequences, suppression thresholds, and domain authentication. Ask how Mark Mei would apply these rules to your list size, engagement windows, and Klaviyo profile bill.
Mark Mei says two personal dropshipping stores hit $1M and the agency later scaled to $2M per year.

The lessons they still apply to client email are concrete: judge email against margin, ad spend, LTV, and fulfillment because they sit on the same P&L; treat every visitor as paid spend, so a pop-up should convert 10–15% when most convert at 1–2%; own the email list because iOS 14 broke Facebook targeting and nearly wiped out both stores; send launches to the most engaged segment first and widen from there; and hire people who have run stores.
Margin-and-LTV review of email performance, higher-converting list acquisition, engaged-segment-first launch sends, and store-operator hiring.
For brands planning a campaign
This gives a DTC brand a way to evaluate retention email beyond opens or attributed revenue.
Ask for examples of email decisions tied to margin, LTV, or fulfillment.
For acquisition, ask what pop-up conversion rates they consider realistic and how they would sequence a launch to protect engaged subscribers.
Experienced operators and low-micromanagement team design
Mark Mei writes that Dahaus Digital has scaled to $500k per month and that scaling past $100k requires hiring people who have already run ecommerce stores, then getting out of their way.
Read more
Every account manager and copywriter has run ecommerce before, and many come from bigger agencies.
They say the agency spends heavily on recruiting because cheap hires create a bottleneck: the founder ends up managing every account, and clients feel the lack of experience.
The same argument appears in two posts.
Recruit account managers and copywriters with direct ecommerce operating experience, pay above market, and avoid micromanagement.
For brands planning a campaign
For a brand choosing a retention email partner, ask who will own the account and write the campaigns, and what ecommerce experience they bring. Ask how the team handles decisions without founder approval on every send; that affects response time and account quality.
Mark Mei's posts describe their e-commerce email agency, Dahaus Digital, and the tools and clients it works with.
Read more
They state that they scaled Dahaus Digital to $500k/mo and previously ran dropshipping stores that reached $1M, though those stores are not named.
The posts also refer to client brands as a group — 30+ eight-figure brands, and brands that have made over $100M from campaigns — without naming any, so no individual client relationship can be identified.
Klaviyo appears as the platform the agency operates in, not as a commercial partner.
Ask about sponsorship, affiliate, investment, or disclosed-partnership relationships, which the posts do not mention.
Dahaus Digital
Owned business
Mark Mei writes as the person who scaled Dahaus Digital to $500k/mo and calls it an e-commerce email agency.
Read more
They describe its operating model: every account gets a four-person pod (account manager, copywriter, designer, Klaviyo technician), three QA checks per email, and account managers and copywriters recruited from bigger agencies who have run e-commerce stores themselves.
Posts describe a dedicated Klaviyo technician on every account, a swipe file of campaign angles that account managers pull from, Klaviyo's Smart Sending Time unlock at 12,000 active profiles, and how Klaviyo bills on stored profiles rather than sends. No commercial relationship between Mark Mei and Klaviyo is stated; the posts treat it as the tool clients' lists live on.
Mark Mei's posts read as a working manual for ecommerce email: what to send, who should receive it and when to stop paying for a subscriber.

Readers new to the work can start with the campaign-planning post, which sets out the angle library and a six-week calendar, then read the large-send segmentation rules to understand the logic behind those sends.
The two posts on running stores and agency staffing show where the judgment comes from.
The ideas take shape as structures: a four-person pod per account, three quality checks before an email goes out, engagement and buyer-status rules for who gets a send, and a six-month suppression line.
To test whether the approach suits you, see how those structures would map onto a list you already know.
Both publish close readings of real email programs and turn their findings into reusable resources.

Schieffer's breakdown of 182 OLIPOP emails tracks how the brand blocks its calendar, hides offers inside ideas and reserves deep discounts for a handful of sale moments. Mei approaches the same ground from the agency side, with a campaign framework, an angle library split into evergreen, offer and holiday ideas, and stated rules for who gets each send.
Schieffer's posts analyse another brand's email calendar and the mechanics of pop-up signup flows; Mei's describe how a client email account is run day to day, including pod staffing, quality checks and monthly campaign volume.
Both write for brands and agencies already spending money without seeing sales follow, and both argue that the angle and the customer's beliefs matter more than polished writing or higher spend.

Bogdanovic's point that cheaper, faster ad creation does not tell you what a customer needs to believe before buying echoes Mei's objection to treating campaigns as discount panic buttons.
Bogdanovic's posts focus on copywriting and paid ads: hook and angle psychology, objection handling, and an offer to review an ad. They do not cover list segmentation, suppression, sending setup or platform mechanics, where Mei's material is densest.
Both teach by walking through real numbers and a fixed order of diagnosis.

Paxton checks tracking, then store conversion, ad-account changes and seasonality before responding to a client; in the home goods case, Paxton weighs contribution margin over a 2.8x blended ROAS. Mei applies the same margin-first lens to email and gives explicit sequence rules for who receives what.
Paxton's cases span paid media and store economics, from Meta retargeting mix to Google Shopping SKUs and shipping thresholds, with post-purchase email as one lever among several. Mei organises everything around email, the agency's only channel.
Use Mark Mei as a retention-email specialist for a DTC ecommerce brand that needs campaign and segmentation thinking.
Read more
The posts address ecommerce operators and email/retention practitioners—store owners, account managers, copywriters, designers, and Klaviyo technicians—and cover campaign cadence, segmentation, deliverability, and agency process.
That supports a placement where the buyer wants practical retention-email experience in the DTC context.
If the campaign depends on specific job roles, company sizes, or geographies, ask for recent audience survey results or platform demographics such as country, age, gender, and job role.
Otherwise, request recent post performance for comparable topics and formats, such as segmentation rules, BFCM sending, or campaign-angle libraries.
Mark Mei's posts describe a done-for-you agency service, not a creator sponsorship offer.
Read more
Dahaus Digital sells retention email management to ecommerce brands, with each account handled by a four-person pod: an account manager, copywriter, designer and Klaviyo technician.
The team runs three quality checks before each send and delivers a minimum of 12 to 15 campaigns a month per client.
Mark describes the team as people who have run their own stores, with account managers and copywriters recruited from larger agencies at above-market pay.
The posts also outline operating details brands can plan around: segmentation rules—regular sends to contacts engaged in the last 30 to 90 days, recent buyers moved to post-purchase flows instead of campaign blasts, VIPs given early access, unengaged contacts held for final-hours sales and drops, and suppression after six months without a click or order—along with sending-domain and DMARC setup, a base frequency of every other day, and a rule that every third email sells nothing.
The posts offer no rate card, sponsorship slot, media kit, audience-usage policy or partnership inquiry page, so there is no creator-partnership format to describe.
The one published resource of this kind is a downloadable campaign swipe file with a framework, roughly 100 campaign angles, calendar planning and send-time testing guidance.
The posts point readers to it but do not specify whether it has a link, a price or a delivery method.
Brands interested in working with Mark should ask whether the swipe file is available and how to get it; the posts describe engaging Dahaus Digital for email management, not buying sponsored content or an audience placement.
Brief: A DTC ecommerce brand doing roughly $100K+/month in revenue wants to reduce discount dependency and improve retention email performance.
Read more
It has a Klaviyo list, weak segmentation, and no clear campaign calendar.
Decision: Mark Mei fits as an agency service engagement, not a sponsored creator placement.
The posts document a done-for-you retention email offer: email-only specialization, a four-person pod per account, three quality checks before send, and 12–15 campaigns per month.
A brand can ask for a campaign calendar, segmentation rules, and deliverability setup.
The work is retention-specific rather than broad channel management; the operating detail is concrete enough to compare with another email agency; and the margin and customer-value lens from running stores is relevant to a DTC retention brief.
Practical next step: ask for a sample six-week calendar and how the pod would apply the 30–90 day engagement segment and six-month suppression cutoff to the brand’s list.
When to choose a specialist
A DTC brand seeking a creator-led sponsored campaign wants a paid post or series in Mark Mei’s LinkedIn feed, with audience reach, product mention, and usage rights.

Decision: not a fit based on the posts here, which describe an agency service rather than a creator sponsorship offer.
There is no rate card, media kit, sponsorship slot, audience-usage policy, or partnership inquiry page.
A brand could still hire the agency for email management, but that is a different need.
For reach or sponsored content, route to a creator with a documented sponsorship format; for retention email execution, use the good-fit route instead.
The commercial format here is the service, not the feed.
A worked campaign example
Worked campaign angle for the good-fit brief: a DTC brand with 20,000 Klaviyo profiles and a discount-dependent list.
Brief: improve retention email without another sitewide sale.
Angle: “The six-month cleanout that funds the next launch.”
Step 1: split the list by buyer and engagement status, using the rules described in the posts: engaged in the last 30–90 days get regular sends; recent buyers stay off campaign blasts and receive post-purchase flow; one-time buyers get a second-order sequence; VIPs get early access; unengaged profiles wait for final-hours sales or drops; lapsed 90+ days get a re-engagement campaign before suppression at six months without a click or order.
Step 2: plan 12–15 campaigns for the month, using the evergreen, offer, and holiday angle mix described in the posts.
Example non-selling angle: a “how it’s made” or myth-buster email that costs no discount.
Every third email sells nothing.
Step 3: set base frequency at every other day, with the full list only for major moments.
Step 4: review email against margin, ad spend, LTV, and fulfillment, not opens.
Step 5: test send times before relying on Klaviyo’s Smart Sending Time threshold.
Expected output: a calendar, segment definitions, a suppression rule, and a test plan the brand can run before peak season.

The OLIPOP analysis maps email themes, offer timing, and channel roles, making it a useful benchmark for brands looking to reduce routine discounting.
The example is a single brand analysis; ask for evidence of results from an ongoing retention program before treating it as a proven model. Mark’s posts provide more directly applicable operating detail on segmentation, suppression, campaign cadence, and email execution.

The troubleshooting sequence checks tracking, site conversion, ad-account changes, and seasonality. A case example also includes a post-purchase sequence alongside paid-media and merchandising changes.
The examples span multiple channels, offering less depth on email strategy than Mark’s posts about audience segments, suppression, and campaign planning. The case study combines several changes, so ask which ones drove the reported improvement.
Six LinkedIn posts about e-commerce email and agency operations appear here; two contain identical text.
