Build a Retention Program That Grows With Every Purchase

Nine in the morning, Tuesday. The campaign goes to the whole list. Twenty two percent of the people receiving it bought the same product eleven days ago. Four percent of them cancelled a subscription last month and are being asked to buy it again. One of them is a customer who has spent nine thousand dollars over three years and is reading the same words as someone who joined yesterday for a ten percent code.

Nothing about that send is broken. That is the problem: it will report a respectable revenue number and it will be quietly training a file to ignore you.

Atelier Commerce is an email marketing agency in New York. We build email and SMS as one program in Klaviyo, Attentive, Postscript, and Yotpo, and we build the customer data model underneath it first, because a message can only be as intelligent as the segment behind it.

The Atelier Perspective

Owned revenue is the only revenue that gets cheaper as you grow. Paid media is priced by auction and the auction never moves in your favor. The list does not charge you more each quarter, it charges you attention, and attention is spent every time a message arrives that did not need to.

So we build for the long file rather than the good month. Flows before campaigns, because flows are the asset and campaigns are the rent. Segmentation before copy. Deliverability before volume. And a monthly pruning habit, because every email program accumulates sends that nobody has questioned in a year.

01

Every Message Has a Job

Each message in the program can name its trigger, its audience, its exclusion, and the number it is accountable for. A welcome message teaches the product. A browse abandonment message answers the objection. A replenishment message arrives at the SKU's real median reorder interval, which we pull from order history rather than guess from the label. If a message cannot name its job, it is a habit, and habits are where list fatigue comes from.

02

Customer Behavior Leads the Strategy

Static lists describe who someone was at signup. Behavior describes who they are on Thursday. We build against RFM tiers, purchase history, product affinity drawn from eighteen months of order data, browse and cart signals, subscription state, loyalty tier, and review activity. A champion who has gone quiet for sixty days gets something different from a one time buyer at the same sixty days, because one is at risk and the other was never yours.

03

Revenue Beyond the First Purchase

Discounting is the fastest way to raise this month's email revenue and the surest way to cap the year's. A file that learns to wait for twenty percent off has been retrained, not retained. We work the other levers: post purchase education that makes the product succeed, the product people actually buy next rather than the one on promotion, loyalty recognition at the third order, and timing accurate enough that the message feels like service.

04

One Connected Retention Engine

Email and SMS are one program with one message hierarchy, one suppression logic, and one calendar. SMS takes the moments that decay fast: cart recovery inside the hour, back in stock, the delivery window, the shipment that is late before the customer notices. Email takes everything that needs room to explain. A customer who has received the text does not receive the same message again by email, which sounds obvious and is the most common defect we find.

OUR Email and SMS Marketing Services

Email and SMS Strategy

We start with the diagnosis: flow inventory read rather than counted, list health and deliverability by provider, consent record, segmentation logic, suppression rules, and the gaps between purchase moments where nothing currently exists. From that comes a ninety day roadmap with four priorities and the number each one is meant to move. Channel roles are defined in writing, so email and SMS stop duplicating each other.

Flow and Automation Development

The flows are the asset: welcome and first purchase, browse abandonment set to forty minutes rather than an hour, cart and checkout recovery sequenced across both channels, post purchase education, replenishment on real reorder intervals, review request timed to arrival rather than to dispatch, win back segmented by reason for leaving, subscription pre renewal and pause, and the VIP logic for the top decile. Each one is instrumented before it ships, with a holdout where the volume allows it.


Campaign Development and Copywriting

Campaigns written for a segment rather than a list, in the brand's voice rather than in email voice. We plan the month against a merchandising calendar, hold the promotional density to a level the file can carry, and keep a permanent record of what each send earned per recipient rather than in gross revenue, which is the number that reveals whether a campaign was worth the attention it cost.


Loyalty and Rewards Integration

Loyalty only works when the messaging knows the balance, the tier, and the distance to the next one. We wire the program into the email and SMS logic so enrollment is offered at the second order, points expiry is a service message rather than a threat, and a tier unlock arrives as recognition. Built alongside our loyalty and rewards work rather than bolted on after it.


Deliverability and Performance Reporting

Authentication done properly, SPF, DKIM, and DMARC, domain warming when a sending domain changes, and inbox placement monitored by the provider rather than inferred from a blended open rate. Sunset rules so that unengaged addresses stop dragging the domain reputation of the people who do want to hear from you. Reporting that separates flow revenue from campaign revenue, shows revenue per recipient, and reports against a holdout so that owned revenue is a real figure rather than an attribution artifact.

what platforms do WE support?

We build in Klaviyo, Attentive, Postscript, and Yotpo, on Shopify, Shopify Plus, BigCommerce, and custom storefronts.

Klaviyo is where most of our email and SMS work lives, because the Shopify data model and the segmentation builder are the closest thing the category has to a proper workbench. Attentive and Postscript are the SMS platforms we build in most often, chosen on compliance posture, carrier throughput, and how the two channel suppression will actually work rather than on feature lists. Yotpo carries reviews and loyalty into the same customer record, which is the difference between a loyalty program that messages and a loyalty program that is messaged about.

Dotdigital, Mailchimp, Braze, and Iterable we work in where a brand is already invested. Migration is a real decision with a real cost and we would rather rebuild your logic correctly where you are than move you for the sake of moving you.

The platform matters. The customer data model underneath it matters more.

FAQ

Everything you need to know about our Email and SMS marketing approach.

What does an email marketing agency do?

An email marketing agency builds and runs a brand's owned messaging program: the automated flows, the campaign calendar, the segmentation underneath both, and the deliverability work that keeps it reaching inboxes. For ecommerce, the useful ones also own the customer data model in the platform, because segmentation quality decides message quality and no amount of copywriting compensates for a bad segment.

Are you a Klaviyo agency?

Yes. Klaviyo is the platform where most of our email and SMS work is built in, from data and segmentation through flow architecture, campaigns, and reporting. We also build in Attentive, Postscript, and Yotpo, and we work in Dotdigital, Mailchimp, Braze, and Iterable where a brand is already committed to them.

Is email marketing dead?

No. Email remains the only channel where a brand owns the audience outright rather than renting reach from an algorithm it does not control. Undifferentiated sending is what has stopped working. Programs that segment on real behavior, run SMS and email as one coordinated system, and measure revenue per recipient against a holdout continue to outperform broadcast programs by a wide margin.

What is a good open rate for email marketing?

Open rate is now a weak metric and should be read as a trend rather than a target, because privacy features inflate it and flows and campaigns are not comparable. Watch your own line moving over time, and read it beside inbox placement by provider: a high open rate on mail landing in Promotions is not the win the dashboard suggests. Revenue per recipient is the number that should drive decisions.

Why is SMS marketing important for ecommerce brands?

SMS is read within minutes, which makes it the right channel for moments that decay: cart recovery inside the hour, back in stock, a shipping exception, a same day promotion. Used as a duplicate of email it burns goodwill and money. Used for the urgent and the operational, with email carrying everything that needs explaining, it lifts the whole program.

How do you measure the ROI of email and SMS marketing?

Measure revenue per recipient and per message sent rather than click through rate, separate flow revenue from campaign revenue because they are built and optimized differently, and run a holdout so the number is incremental rather than attributed. Opt out rate and list growth net of churn should sit on the same report, since a program can post a good month while shrinking the asset.

What is the best time to send SMS for marketing?

There is no universal best time, and the question is usually the wrong one. Triggered messages should fire on the behavior, so a cart text belongs close to the abandonment rather than in a send window. For broadcast sends, test against your own file inside the hours your audience's time zones allow, and respect quiet hours as a compliance requirement rather than a courtesy.
