The problem

Paid acquisition gets more expensive every quarter. Your list does not.

Most brands pour everything into ads, then let hard-won customers leak out the back door. The math is brutal: rising CPMs, privacy changes, and one-and-done buyers. Retention is the highest leverage fix, and email and SMS are how you pull it.

The benchmark

Where revenue should come from

If email and SMS drive less than 25 percent of your revenue, you are leaving money on the table every single month. Our portfolio average sits at 38 percent, with flows doing most of the heavy lifting on autopilot.

Cheaper than re-acquiring them on Meta

A lapsed customer already trusts the product, which makes them far cheaper to reactivate than to replace. This send leads with brand voice, sizes the incentive to the length of the lapse, and keeps the list clean by sunsetting anyone who stays cold.

Deliverability

Stop paying the spam tax

When a quarter of your list never sees your emails, every flow and every campaign quietly underearns. We do the unglamorous work that keeps you in the inbox, and the result is the cheapest revenue you will ever add: the emails you already send, finally arriving.

Numbers we can stand behind

Every engagement is measured against one thing: attributed revenue you can see in your own dashboard.

How it works

Live in 30 days. Compounding by 90.

A fixed sequence we have run dozens of times, and not a single meeting in it. You will know exactly what is happening at every step.

STEP 01 2 minutes

Tell us about the store

Seven quick questions, no call, no calendar. If your store is a fit, we text you same day to set up read-only viewer access on your Klaviyo. You never share a login.

STEP 02 Days 1 to 5

The no-call audit

We go through your account and test your live flows as a real subscriber: signup, abandon, purchase. Then we record a video audit with a scored teardown and a 30, 60, and 90 day plan.

STEP 03 Your pace

Watch it, then decide

The video and the plan are yours to keep either way. If the math makes sense, onboarding starts with one text back. Still no meeting required.

STEP 04 Weeks 1 to 4+

Build and compound

The money flows are rebuilt and live within 30 days, campaigns start, and every month is measured against the plan. Weekly tests, async updates, no mandatory meetings.

Your options

The honest comparison

There are three ways to run retention. Here is how they actually stack up for a brand doing $100k to $2M a month.

	Tall Pines	Typical agency	In-house hire
Senior strategist in your account daily	✓	✕	Depends
Copy, design, and build included	✓	Extra fees	✕
SMS compliance handled	✓	Sometimes	✕
Revenue guarantee in writing	✓	✕	✕
Month to month, cancel anytime	✓	6-12 mo lock	✕
Time to first revenue lift	30 days	60-90 days	3-6 months
True monthly cost	$4,000 to $7,000	$6,000 to $12,000	$9,000+ loaded salary

The 90 day proof guarantee

If we do not lift your email and SMS attributed revenue by at least 30 percent in 90 days, we keep working for free until we do. No long contracts either. Every engagement is month to month after the initial build, because results should be the only thing keeping you here.

What clients say

Founders who stopped worrying about retention

We tried two agencies before Tall Pines and both sent pretty emails that made no money. These guys talk in revenue per recipient and flow conversion rates. Email went from an afterthought to our second biggest channel.

Lauren M.

Founder, skincare brand

The audit alone was worth more than what our last agency did in six months. They found a deliverability issue that was silently costing us five figures a month and fixed it in the first two weeks.

Ravi S.

CEO, supplements brand

I approve two things a week and that is my entire involvement. Meanwhile owned revenue is up 41 percent year over year and our ad dependence keeps dropping. Easiest vendor decision we have made.

Anna K.

CMO, apparel brand

Questions

Before you book

What does this cost?+

Engagements start at $4,000 per month for email only and $5,500 per month for email plus SMS, with a one time build fee for the initial flow architecture. No percentage of revenue, no long contracts. You will get an exact quote alongside your audit, based on your list size and send volume.

What platforms do you work with?+

Klaviyo is our home base for email. For SMS we run Klaviyo SMS, Postscript, and Attentive. If you are on Mailchimp, Omnisend, or anything else, we will tell you honestly whether to migrate, and we handle the migration if so.

How fast will we see results?+

Core flows go live within 30 days and start producing immediately. Your audit video lands within days of the form, and most clients see a clear lift in attributed revenue by day 45, hitting the full 30 percent lift inside the 90 day guarantee window. Deliverability repairs, when needed, can show results even faster.

Do we need a big list for this to work?+

You need real order volume more than a big list. Our sweet spot is brands doing $100k or more per month in revenue. Below that, the math on a full agency engagement usually does not favor you, and we will say so up front.

Who actually does the work?+

A dedicated pod: one retention strategist who owns your account, plus a copywriter and a designer. No account manager relay, no outsourcing. You talk directly to the person making decisions in your account.

What about deliverability?+

It is built into every engagement, never sold as an add-on. We verify your sender identity, prune unengaged addresses monthly, ramp volume instead of blasting, and check where your mail actually lands every week. If your sender reputation is already damaged, repairing it comes first, and it is often the fastest revenue win in the whole plan because every email you already send suddenly starts reaching people.

What if we already have flows set up?+

Most of our clients do. Existing flows are usually under-segmented, under-tested, and missing the highest leverage messages. The audit shows you exactly what is working, what is leaking, and what the rebuild is worth in dollars before you commit to anything.

Tall Pines

See if we’re a fit

Seven questions, two minutes. We evaluate up to 12 brands a month. If yours is a fit, we text you and get to work on your audit and 30, 60, 90 day plan. No call required.
