Ecommerce Email Marketing Agency

CaesarMails is an ecommerce email marketing agency built around a simple operating principle: the people who plan your programme are the same people who execute it and answer for the numbers. There is no strategist who writes a deck and then disappears, and no account manager translating between you and whoever is actually working inside your Klaviyo.

That structure exists because retention is not a campaign, it is a system. Flows, segmentation, sending frequency, deliverability, SMS and offer strategy all move together, and the moment they are split across four teams who each own a slice, the system stops compounding. Every result on this site, more than $30M in attributed email revenue, came out of running all of it as a single programme.

What you get is an email and SMS programme built around how your customers actually behave. Welcome and abandoned cart sequences that recover revenue you are currently losing, post purchase and win back flows that turn one time buyers into repeat customers, and a campaign calendar planned around your margins and your goals rather than a generic send schedule.

Email Marketing Advertising Agencies

Strategy, copy, segmentation and timing handled together, so every send has a job to do.

Choosing between email marketing advertising agencies is harder than it should be, mostly because so many of them sell the same thing under different names. A lot of what is marketed as email marketing is really just newsletter production: someone sends a branded email once a week, reports the open rate, and calls that retention. It keeps the calendar full and it moves almost nothing on your P&L.

The difference is whether each send has an objective attached to it before it is written. Every campaign we build has one, and the objective decides everything downstream. Promoting a specific product to people who have browsed it is a different email, sent to a different segment, at a different time, than reactivating customers who last bought nine months ago. When those two get the same newsletter, both underperform, and the account looks like it has hit a ceiling when it has simply never been segmented properly.

We bring together the pieces that usually sit with separate people: copy that sounds like your brand rather than a form letter, audience segmentation built on real purchase and engagement behaviour, and the timing that decides when each message lands. Because those decisions get made in the same room, the segment shapes the message and the message shapes the offer, instead of a brief travelling down a chain of people who have never looked at the account.

Everything is measured against revenue rather than vanity metrics. Subject lines, sending times, offer structure and calls to action are tested continuously, at a minimum of two meaningful A/B tests per week focused on lifecycle performance. Open rate is useful as a diagnostic and useless as a goal. The number that matters is what percentage of your total revenue email and SMS are responsible for, and whether that percentage is higher this month than last.

The results of that approach are on the case studies page in full. One brand went from 25.16 percent of revenue attributed to email up to 39.07 percent, with email alone moving from $383,309 to $793,840 a month. Another went from $168,892 to $319,437 in monthly email revenue, an 89 percent increase. A third took email from a standing start to $1,818,924 in a single month, 39.45 percent of total revenue and up 775 percent year over year.

Email Marketing Agency for Ecommerce

Retention that raises LTV and repeat purchase rate, not just this month's send volume.

As an email marketing agency for ecommerce, the job is to make email one of the most profitable channels you own. That is a specific claim and worth unpacking, because it is not true of most channels. Paid acquisition gets more expensive as you scale it. Email gets cheaper, because the list compounds and the flows you build this quarter keep earning next year with no additional spend attached to them.

The work covers every stage of the customer journey. Welcome sequences that convert first time visitors while intent is still high. Abandoned cart and browse abandonment flows that recover the revenue currently walking out of your checkout. Post purchase sequences that set up the second order before the first one has even arrived. Win back campaigns for customers who have gone quiet, and replenishment timing for consumables so the reminder lands when the product is actually running out.

All of it is behaviour triggered rather than calendar triggered. A flow that fires because someone abandoned a $400 cart should not look like the one that fires for a $30 cart, and a customer on their fourth order should never receive the same first purchase discount as someone who has never bought. Getting that right is most of the difference between an account at 20 percent attribution and one at 38 percent.

Segmentation is where the majority of the gain usually sits. Most stores we take over are sending close to the same message to their entire list, which quietly trains their best customers to ignore them and pushes their deliverability down at the same time. Splitting the list by purchase history, engagement recency, product affinity and value tier means the volume goes up without the fatigue, because each person receives fewer emails that are more relevant to them.

SMS runs alongside it rather than as a separate programme. Used carefully it is the highest urgency channel you have, which makes it excellent for launches, restocks and closing windows, and terrible for anything routine. Coordinating the two so a customer does not get hit twice with the same message on the same afternoon is a large part of why running both under one roof works better than splitting them between vendors.

Always On Revenue

Email Marketing Automation Agency

The flows that earn while you are asleep, monitored and tuned rather than set and forgotten.

As an email marketing automation agency the goal is straightforward: send the most relevant message to each customer at the moment it is most likely to work, without anyone having to press a button. Automation is what turns email from a channel that costs you time every week into infrastructure that produces revenue continuously.

In practice that means a set of flows covering lead capture, cart recovery, post purchase, replenishment, win back and VIP treatment, each one built against your specific catalogue and margins rather than lifted from a generic playbook. On one account, rebuilding the flow layer took automated revenue from $234,099 to $635,737 a month, and flows went from 61 percent of attributed revenue to 77 percent.

The part most agencies skip is what happens after launch. Automated does not mean finished. Flows decay: offers get stale, products go out of stock, the timing that worked in Q1 stops working in Q4, and a broken conditional split can quietly leak revenue for months before anyone notices. We monitor open, click and conversion rates on every automation and fine tune continuously, running A/B tests inside the flows themselves rather than only on campaigns.

Deliverability sits underneath all of it. There is no point automating anything if it lands in the promotions tab or the spam folder, so sending reputation, list hygiene, authentication and engagement based suppression are managed as part of the work rather than treated as an emergency when something breaks. A clean list that receives relevant mail is the cheapest deliverability strategy there is.

List growth sits alongside it, because automation only compounds if new people keep entering it. Opt in offers, placement and timing are tested and iterated to feed the welcome flow, and the welcome flow is usually the highest converting sequence in the entire account.

FAQs

Email Marketing Agency FAQs

The questions we get asked most often on audit calls.

What does an email marketing agency do?
An email marketing agency plans, builds and runs the email programme that turns your existing customers into repeat revenue. In practice that means automated flows triggered by customer behaviour, a campaign calendar aimed at your business goals, list segmentation, copy, deliverability management, and continuous testing. The good ones report on revenue and attribution rather than open rates. Here you also get SMS handled in the same system, because running the two separately is how customers end up receiving the same message twice in one afternoon.
Why should I use an email marketing agency instead of doing it in house?
Two reasons, and neither is that you cannot do it. The first is opportunity cost: building flows properly is a specialist job, and the person doing it internally is usually doing three other jobs at the same time, so it never gets past the basics. The second is pattern recognition. Having run more than $30M in email revenue across 35+ accounts, we have already made the expensive mistakes on someone else's account. If you have an in house team already, the honest answer is often that you do not need us, and we will tell you that on the call.
Is email marketing still effective for ecommerce businesses?
It is the most profitable channel most stores own, and it gets better as you scale rather than worse. Paid acquisition costs rise as you push volume. Email costs stay effectively flat while the list compounds, and flows built once keep producing for years. Across the accounts on this site, email and SMS sit between 30 and 40 percent of total revenue. If yours is well under that, the gap is not a sign that email is dead, it is the size of the opportunity.
How much of my revenue should come from email?
For most 7 and 8 figure eCommerce brands the healthy band is 30 to 40 percent of total revenue attributed to email and SMS. Below 20 percent almost always means the flow layer is thin or the list is being sent to as one undifferentiated block. Above 45 percent can be its own warning sign, because it often means acquisition has stalled and email is propping up a shrinking business. The right target depends on your margins, purchase frequency and list size, which is what the audit is for.
Which platforms do you work with?
Primarily Klaviyo, and Omnisend where a brand is already established on it. We are partners on both. The case study screenshots on this site are pulled straight from client accounts on those platforms rather than rebuilt in a reporting tool. If you are on something else and considering a move, migration is part of the work, including preserving your sending reputation through the switch rather than starting from zero.
How long before I see results?
Most brands see improvement inside the first 30 days, because the fastest wins are usually sitting in a broken or missing flow. By day 60 to 90 the compounding starts to show. One brand hit $1.8M in email revenue in a single month. Another took monthly email revenue from $168,892 to $319,437. Your starting point, list size and purchase frequency all change the timeline, so the audit gives you a realistic version rather than a brochure version.
How does pricing work?
It depends on your brand size, your goals and how much of the system already exists. Rebuilding an account from nothing is a different scope to optimising one that is already at 30 percent attribution, and pricing reflects that. We talk numbers on the call once we have seen the account, rather than quoting a package before we know what is in front of us.
Who actually works on my account?
The same people who built your programme. There are no layers and no hand-offs. You get daily access over Slack, weekly reporting, and calls at whatever cadence suits you. This is also the reason we take on a limited number of brands at a time. It is the main constraint on the model and the main reason it works.
