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.

What we do

One team. The entire retention stack.

Strategy, copy, design, build, and reporting. You approve, we ship. Nothing falls on your plate.

Email flows and campaigns

The automated core that prints while you sleep, plus a campaign calendar that keeps revenue compounding.

  • Welcome, abandonment, post purchase, winback, and VIP flows
  • 8 to 12 campaigns per month, written and designed
  • A/B testing on subject lines, offers, and send times

SMS that converts

Short, well timed, and compliant. SMS regularly out-earns email per send when it is run correctly.

  • Transactional and promotional SMS journeys
  • TCPA and carrier compliance handled for you
  • Two way conversational SMS for high AOV products

List growth and deliverability

A bigger, cleaner list that actually lands in the inbox. The unglamorous work that moves every other number.

  • Popups and signup units tuned to 6 to 10 percent opt in
  • Domain warmup, DMARC, and sunset segmentation
  • Monthly list hygiene and inbox placement monitoring
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.

Portfolio average across 40+ active clients, trailing 12 months
TYPICAL BRAND 14% 86% dependent on paid and organic TALL PINES CLIENT 28% email 10% 38% owned, margin-rich revenue Email SMS Everything else
The work

Designed to be opened. Written to convert.

Six sends from the flows we build for every client, shown the way subscribers see them. Pick a flow. Every example is fully branded, mobile first, live text, and dark mode tested. Your brand will look this good, not ours.

Every send ships as a system, not a one-off. Desktop and mobile versions, live text for deliverability, dark mode tested, and a documented module library your team owns forever.

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. You will know exactly what is happening at every step.

STEP 01 Week 1

Audit and roadmap

We tear down your current account: flows, segments, deliverability, popup, and calendar. You get a scored audit and a prioritized 90 day plan, free, whether you hire us or not.

STEP 02 Weeks 2 to 4

Build the core

We rebuild the money flows first: welcome, abandonment, post purchase, winback. Copy, design, and logic shipped for approval in batches so nothing stalls.

STEP 03 Week 5

Launch and ramp

Flows go live, the campaign calendar starts, and SMS begins its compliant warmup. Deliverability is monitored daily through the ramp.

STEP 04 Ongoing

Test and compound

Weekly A/B tests, monthly strategy calls, and a live revenue dashboard. Every month beats the last or we tell you exactly why and what changes.

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.
RS
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.

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 on the audit call 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. Most clients see a clear lift in attributed revenue by day 45 and hit 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 on the call.
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 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.
