Hear It Directly From Our Clients

Here's what they have to say about working with us:

“This is quality work. A lot of other people talk, but it seems like they don’t have an idea of what they’re really talking about. [The audit] provided a lot of actionable insights that we could get started on and helped refine our email strategy. It’s a solid framework that I still continue to revisit 9 months later.”

“I would recommend Matt to any Ecommerce business struggling to get their email marketing function established. Matt was able to come in and hit the ground running with the guidance and brand assets we were able to equip him with. We greatly appreciated the expertise he brought to the table and the willingness to share wins from other clients of his that could be applied to our business and case.”

OUR PROCESS

The ACR Model™

Everyone's business is different. Where most programs are built around conversion, we audit and build against three main stages of the customer journey – acquisition, conversion, retention – so we can identify what's bottlenecking your business' growth and use your Owned Media Channels to close that gap.

A
Acquisition

Converting more of the traffic you're already paying for.

The bottleneck

You're spending a fortune on paid ads, creative, SEO, etc... and people are leaving your site without capturing their data.

C
Conversion

FAQ

Frequently Asked Questions

Ask Us Directly

If it isn't answered here, email us.

matt@thekaizenblitz.com
What does it cost to work with you?+

Depends on what you need. We'll walk through pricing in more detail on the call once we understand your list and goals. We generally start with a focused 30-90 day sprint as a one-time fee (ranging from $1,500 to $6,000), then an optional monthly retainer. The call itself is completely free, with zero obligation.

Do you offer a guarantee?+

We treat email as performance marketing, so you should expect a return after discounts, expenses and our fee. If you do not see positive ROI, we keep working until you do at no extra cost.

Is there a contract or minimum commitment?+

No. Everything's month-to-month. If you want out, give us 14 days' written notice before your next billing cycle. We'll wrap up active work, document everything we built, and hand it over. If you would rather pay less, three months upfront takes 10% off.

How fast will we see results?+

List growth moves in the first two weeks. Core flows are live and generating by month two. By month three, email and SMS should be driving 35–50% of total revenue. Any agency promising you a specific dollar figure before seeing your account is guessing.

Who's this for – and who isn't it for?+

We're not for everyone. We primarily work with DTC brands doing $1M+/year that are growing and are running paid media (Meta, Google, TikTok). We've worked across 13+ industries — supplements, cookware, jewelry, you name it.

If you're pre-launch, want to micromanage every little detail, or you're not ready to get started in the next 60 days, then we're not the agency for you.

Do you actually do the work, or just hand us a strategy?+

We execute. Strategy, copy, design, build, send, report – all of it, inside your account. And you're not getting handed to a junior after the sales call. The same small team that scopes your account runs it, and Matt's in every client Slack channel.

We already have someone doing email. Does that matter?+

Usually not. Plenty of clients come to us with an in-house marketer or another agency already in the account. We either take the channel off their plate entirely, provide support on pieces they don't have capacity for, or provide strategic direction that's beyond their scope of work. Sometimes we'll just tell you to keep what you've got.

Do we have to be on Klaviyo?+

No. Klaviyo's where we spend most of our time, but we work in Omnisend, Braze, Postscript, PostPilot, and similar ESPs too. If you're on something else and want to move, migration is one of our project services.
