The email channel can carry 45% of your revenue.

What an email marketing agency is for
| Part | What it does | The number it moves |
|---|---|---|
| Welcome and abandon-cart flows | Catch buyers while intent is hot | Revenue on autopilot |
| Campaigns and promotions | Sell the calendar: launches, seasons, inventory | Orders you can plan around |
| Segments | Different message per buyer, never one blast | Repeat rate and deliverability |
| SMS | The same list, read in minutes | Time-sensitive revenue |
| List health | Reaching the inbox at all | Every other number on the scorecard |
The audit reads every row against your revenue before anyone proposes a template.

Klaviyo, or something else
| Platform | What it is | Best when |
|---|---|---|
| Klaviyo | The ecommerce standard: flows, segments, revenue reporting | Revenue runs through your store |
| Omnisend | Ecommerce-focused with simpler tier pricing | The store is smaller and getting started |
| Mailchimp | General purpose with broad integrations | Email is a side channel to the business |
Reviewed September 2026 from each platform’s public positioning. ROI.LIVE works in Klaviyo for the receipts on this page, and software is billed at cost either way: the platform invoice comes to you, so there is no margin on it.

Who this is for, and who should not call
Hire me if
- You run a store between $1M and $10M with real order volume.
- Email is a rounding error of revenue and nobody is sure why.
- You send campaigns but the flows are thin or stale.
- Your last send went to the whole list, twice.
- You want the program tied to the P&L, with one owner.
- You will act on what the data says, even when it stings.
Do not hire me if
- You are pre-revenue with no list and no buyers yet.
- Your sales run one-to-one on relationships. Email supports that; it will not carry it.
- You want to trade equity for marketing help.
- You need someone on site five days a week.
- You want a welcome flow handed over in thirty minutes.
- You are not willing to hand over the marketing decisions.

Questions owners ask before they book
What does an email marketing agency do?
It runs the program that turns a store list into repeat revenue: automated flows like welcome and abandon cart, the campaign calendar, the segments that keep messages relevant, and the deliverability work that keeps it all reaching the inbox. On the ROI.LIVE model the same operator who runs email owns the rest of the plan, so email and paid feed each other instead of competing.
How much does email marketing cost?
ROI.LIVE retainers run $5,000 to $15,000 a month, scaling with scope, and email sits inside the same retainer as the rest of the plan. Software is billed at cost: the Klaviyo invoice comes to you, so there is no margin on your platform. Ad spend and third-party production are separate too, never marked up.
Is Klaviyo worth it for a store?
For a store with real order volume, it is the tool the receipts on this page were earned in: flows, segments, and revenue reporting built around ecommerce. Smaller stores can start on simpler platforms and migrate when the program outgrows them. The platform matters less than who runs the program; a clean program on a modest tool beats a mess on a premium one.
How long before email pays for itself?
The audit reads your flows, segments, and revenue per recipient in the first two weeks. Rebuilt welcome and abandon-cart flows usually show their effect inside the first month, because they fire on demand you already have. The compounding layer, segments and lifecycle work, builds over the following two quarters. That is the honest shape of the curve.
What is a good revenue per recipient?
Your own baseline, and then a rising trend. Public benchmarks cannot see your list, your price point, or your margins, so they cannot tell you what your list should produce. The first month of work sets the baseline; every month after is measured against it on the scorecard.
Will email cannibalize my paid ads?
The opposite, when the two share an owner. Email repeats the customers paid acquired, which raises lifetime value and pays for the next acquisition. At CRAFT, email carried 45%+ of revenue while paid held 4x ROAS in the same year. The channels feed each other, and splitting them across two vendors is how that link gets lost.
Do you run SMS too?
Yes, where it earns its place. SMS is the same list read in minutes, which suits time-sensitive offers and back-in-stock moments, and it punishes overuse faster than email does. It gets layered in when the data says the list will tolerate it, not because a platform dashboard suggested it.
What about deliverability?
Deliverability is table stakes: reaching the inbox at all is the precondition for every other number on the scorecard. Segmentation, list hygiene, and sending to people who engage are what protect it. A list that gets blasted ignores these rules and pays for it at the spam filter.
Agency, freelancer, or in-house for email?
A freelancer who only builds flows leaves nobody owning the number. An in-house hire at this stage is expensive for one channel. The ROI.LIVE structure puts one senior operator over email and the rest of the plan, with named specialists doing production underneath. At $1M to $10M, that is usually the shape that fits.
How do I start?
The free growth plan call opens your numbers together, or the $2,500 Growth Constraint Snapshot delivers the constraint diagnosis in writing. Either way the first move is reading what the list already produces before anyone builds a template. Most programs are sitting on recoverable revenue before they need new creative.
