Want to know what your account is doing?Book your free auditHow it works
Four jobs, run as one system.
Inferno Emails is an email marketing agency for ecommerce brands. We build Klaviyo flows, design campaigns that look like your brand, and fix deliverability so the revenue actually lands. Founded in 2022, working with ecommerce brands in Europe, Australia and the United States. The first step is a free, no-obligation audit of your account.
Klaviyo email marketing
Flows and campaigns built in Klaviyo, mapped to how people actually buy from you, not a template pack dropped into your account.
What is included in klaviyo email marketingEmail design
Emails designed to look like your brand rather than like an email. Every campaign in our portfolio was built from scratch.
What is included in email designEmail deliverability
The best offer in the world earns nothing from the spam folder. Authentication, reputation and list hygiene, handled.
What is included in email deliverabilityRetention strategy
One-time buyers are fine. Repeat buyers are the business. We build the lifecycle that turns the first into the second.
What is included in retention strategyFlows are their own job too. Email flows and automation, or see all five services.
Audit. Build. Compound.
No ninety-day discovery phase. We are in your account in week one and sending by week two.
See the account screenshotsAudit
We go into your account before we pitch you anything. Flow coverage, list health, authentication records, segment quality, what your last ninety days actually earned. You get the findings whether or not you hire us.
Build
Core flows first, because they compound while everything else is still being approved. Then the campaign calendar, designed in your brand, with a reason behind each send rather than a slot to fill.
Compound
Test, cut what loses, scale what wins. Monthly reporting against attributed revenue and repeat rate. The account should be worth more every quarter than it was the last one.
Step one is free, and it is the whole first call

Every agency wants your money. We want the account.
Building email and retention programmes for ecommerce brands since 2022, across apparel, coffee, bakery, wellness and kitchen goods in Europe, Australia and the US.
Most brands treat email as an afterthought: a sale newsletter bolted onto three half-built flows, while the customers who already trust them barely hear from them. We take that channel over and run it properly.
You grow, we grow. That is the entire business model.
Our aim: Turn your email list into your most profitable channel.
What we believe
Attributed revenue, or it did not happen
Opens are a diagnostic. Clicks are a diagnostic. The number that decides whether we earned our fee is how much revenue the channel attributed this month, and whether it is bigger than last month. We report on that first, every time.
Templates are a tax on your brand
A layout that has been sold to four hundred other stores does not stop looking like a layout that has been sold to four hundred other stores. We draw every email for the brand it belongs to. It costs us more time. It is the whole job.
The boring part decides the exciting part
Authentication records, list hygiene, sunset flows, send-time discipline. None of it is fun to talk about on a sales call, and all of it determines whether your best campaign of the year gets seen at all.
We tell you when the answer is no
If your list is too small to justify the spend, or the problem is your offer rather than your email, we will say so on the audit call. Selling you a retainer you should not buy is a bad month for you and a bad year for us.
We are a very good fit for some brands and a waste of money for others.
Good fit
- Ecommerce brands with consistent monthly revenue and an existing list
- Klaviyo already installed, and visibly under-used
- A brand with a real point of view that templates are flattening
- Teams who want one partner owning the channel, not four suppliers
- Founders who will look at an attributed-revenue number honestly
Bad fit
- Pre-revenue stores with no list to email yet
- Anyone looking for a one-off template pack and no strategy
- Brands whose core problem is the product or the offer, not the channel
- Businesses that want to buy or scrape a list, which we will not send to
- Anyone who needs a guaranteed revenue figure promised before the audit
Not sure which you are? Book your free audit. We will tell you straight, and you can walk away with the findings.
Don’t just take our word for it.
“I never thought email marketing could bring us that big a share of revenue.”
“Their email design made me reconsider and revamp our whole site.”
“They understood our vision from day one and led an amazing jump in revenue.”

The free audit
Four things that decide almost everything.
Before the call we review your account properly. By a person, not an automated PDF generator.
Flow coverage
Which of the money flows exist, which are half-built, and which are quietly switched off. Welcome, abandoned cart, browse abandonment, post-purchase, winback.
List health
Engagement decay, share of your list that has not opened in six months, suppression hygiene, and whether unengaged contacts are dragging your reputation down.
Deliverability
SPF, DKIM and DMARC records checked and verified. Complaint and bounce rates against the thresholds Gmail and Outlook actually enforce.
Last ninety days
What the channel earned, split between flows and campaigns, revenue per recipient, and the gap between what it did and what it should be doing.

What does Inferno Emails do?
We run email and retention marketing for ecommerce brands. That means building and managing Klaviyo flows and campaigns, designing every email from scratch in your brand, fixing deliverability so those emails reach the inbox, and building the lifecycle that turns first-time buyers into repeat customers.
What size brand do you work with?
Mostly ecommerce brands doing consistent monthly revenue who have Klaviyo installed but are not getting much out of it. If you are pre-revenue or have no list yet, we are probably the wrong spend for you right now, and we will say so.
How much does email marketing management cost?
It depends on scope: flow build only, full management, or design support alongside your in-house team. We quote after the audit, because quoting before it would be a guess. The audit itself is free.
How long until we see results?
Campaigns can start earning in the first few weeks. Flows compound over months as more people enter them. Deliverability repair, where it is needed, typically takes four to eight weeks. Anyone promising a fixed number by a fixed date has not looked at your account.
Do you only work in Klaviyo?
Klaviyo is where we do our best work and where most ecommerce brands already are. We have worked in Mailchimp, Omnisend and Shopify Email too, and we can migrate you if it makes sense.
What happens on the free email audit?
You send us access or screenshots, we review your flows, list health, authentication records and last ninety days of performance, and we send back what we found and what we would do about it. No obligation, and the findings are yours to keep.
Is the audit actually free?
Yes. There is no fee and no obligation. We send you the findings whether or not you hire us. If the report is useful and you fix it yourself, that is a fine outcome for us.
What access do you need?
Read-only access to your Klaviyo account is fastest and most useful. If you would rather not grant access, screenshots of your flow list, your last 90 days of performance and your list growth will get us most of the way there.
Will this turn into a sales call?
You get the findings in writing either way. If we think we can help we will say what we would do and what it costs. If we do not think we can help, we will tell you that instead.
What if I am not on Klaviyo?
We can still audit Mailchimp, Omnisend, Shopify Email and most other ESPs. The flow and deliverability questions are the same everywhere; only the interface changes.
Find out what your list is actually worth.
Pick a time and we will walk your account with you: what is missing, what is leaking, and what we would do about it. No fee, no obligation, and the findings are yours to keep.
- Reviewed by a person, not an automated PDF generator
- One business day turnaround if you send it in writing
- Written findings you can hand to any agency, including not us
