The Best Email and SMS Marketing Agency In The Game

The Inbox Newsletter

Hey it’s Max from The Inbox Newsletter.
I opened Twitter today and saw an unprompted tweet from a client of ours expressing how they feel about our email and sms marketing services.
We never asked him to say this, he just said it.
Here’s what the Tweet was:

We do over 50% of their revenue from email / sms for their insanely fast-growing brand.
Thank you Dana and the team at Proof Products for the shoutout and making things easy on us. Killer brand + killer team makes out lives a lot easier.
We are about to close onboardings for our services for Q4 to focus just on our clients for BFCM.
If you want to destroy your Q4 projections, book a call with us here.
Email Mentorship Launching WEDNESDAY OCTOBER 1ST
My biggest news ever… you’ve probably heard already.
But I'm opening a private 90-day mentorship for a small group of 10 brands. Private Slack, group, calls with me, 24/7 access to my team, exclusive templates, and a full email course.
We’ll work directly with you to build your full email engine from scratch… flows, campaigns, segmentation, calendar, everything.

Why Is Having Email DIALED Important Right Now?
Email has 4 billion users globally and 79% of Americans check their email every day.
The best part, is that emails cost a fraction of a penny to send.
When done right, email consistently drives 30–50% of store revenue, and it does it without discounting, without relying on new customer acquisition, and without you working 24/7.

Brand We Recently Started Working With and Their Last 30 Days of Performance
Why Should You Do This Now?
Conversions are harder to win in a saturated 2026 ecommerce market
Ad costs are skyrocketing (and they aren't going down)
Customers are more distracted than ever and harder to convert profitably
The brands that are thriving in 2026 aren’t the ones spending the most on ads…
They're the ones squeezing the most out of their ads.
They’re the ones who’ve built a backend system that makes the most out of their site traffic…
Turning one time site visitors into leads, and leads into long-term customers.
Why Not Figure It Out On Your Own?
Email is overwhelming and there's a lot to learn to build a strong system.
So… Most brands either:
A) Piece together half-baked flows from outdated YouTube tutorials
B) Rely on inexperienced freelancers who don’t understand full-funnel ecommerce.
C) Hire agencies who really don’t care about their brand / are just there to cash their monthly retainer
All of these scenarios leave the brand's email program underperforming… Their ads less profitable… And leaves them with a lack of confidence to scale their brand profitably.
The worst scenario? You don't join our program, you try to do email on your own, you have no accountability, and 6 months later you still don't have email fully set up and you've lost tens of thousands of dollars by not having a proper email system running.
Why Listen To Us?
We've generated over $150M in email revenue in the past 18 months.
We've worked with 200+ 7-9 figure brands to build the exact systems we are showing you.
Our partners average 41% of their total store revenue from email & sms
Who Is This For?
There are a few different kinds of brands we build this program around…
Brands that know email is important but haven’t gotten to building their full system and are a bit overwhelmed on what to install / what is working in 2025
Brands that aren’t ready to spend $4k–$6k/mo for a done-for-you email marketing agency but want help with email
Brands that already have in-house teams, but just want expert guidance to really scale their channel to the next level
Brands looking for ongoing consulting, but not done-for-you services
Who is it NOT for?
Agencies or freelancers, this is an ecommerce brand only group
How Much Time Do You Need To Commit?
Depends on where you’re starting from…
But we built this program with the idea of you only needing to spend 5-10 hours per week on the email channel.
We provide all templates and strategies for you to eliminate any guesswork and get you results as fast as possible.
If you’ve got a team helping you, it’s even less.
Is This Right For You If Your Store Is Smaller?
Yes. We built this for smaller brands that want to punch above their weight and create a legit retention system before scaling traffic.
Invest in this system now and it will help you scale a lot easier and faster.
You are also investing in your ecommerce knowledge.
If you want to have a successful store, you need to understand email marketing through and through.
Even if you're doing $5k/mo, you will get an immense ROI.
What Email Platform Do You Need?
Any platform works and we will work with whatever you are using.
Our two recommended options are Klaviyo and Omnisend.
Can Your In-House Marketer(s) or Team Join?
Absolutely. This is perfect for founders + their marketing teams.
You get one extra person who can join the channel, calls, and content with you for no extra price.
Do You Need An Existing List Or Can You Start From Scratch?
Either works… existing list or no list.
We’ve helped brands go from 0 → $30k+/mo in 45 days with no list.
If you have a list, great! We’ll help you maximize it.
If you don’t have a list, great! We’ll help you grow it fast and monetize from day one.
How Much 1:1 Access Do You Get To Us?
You’ll get 24/7 access to both myself and my team.
Slack access = daily replies from me and my team.
Live weekly → bi-weekly calls = direct strategy and Q&A with me.
You’re not just getting shoved into a group and ghosted… we’re in the trenches with you.
How Much Does It Cost?
It is $4000 up-front for the full 90 days (it will be $6000 once we launch it to everybody).
One-time payment. No hidden fees. No retainers. No lock-in. Just 90 days of stacked value.
Is There a Refund Policy?
Yes there is a refund policy.
If after the first 14 days you feel like it’s not what you expected and you’ve actually shown up and implemented, we'll refund you.
What Happens After The 90 Days?
You’ll walk away with a fully built, optimized email engine.
But if you want ongoing help, you’ll have an option to extend your mentorship access on a month-to-month basis (totally optional).
How To Get Started
Look out for future emails on the drop next week.
The process: Fill Out Application → If qualified, book a call → If qualified on call and it makes sense for both sides, pay the invoice → Onboarding commences (if you are one of the first 10 brands)
