What does a retention marketing agency do?
A retention marketing agency grows revenue from customers you already have, using email, SMS, loyalty and subscription programs. Good ones build automated flows, run campaigns, test offers and report on repeat purchase rate and customer lifetime value. Ralph decides what your program needs, then places the agency or specialist that fits your size.
Signs your retention needs work
- Most revenue comes from first-time buyers, and acquisition costs keep rising.
- Your email program is a weekly discount blast.
- Flows were set up once, years ago, and nobody has touched them since.
- You have SMS, but nobody can say what it earns.
- You don't know your repeat purchase rate or what a customer is worth over 12 months.
What's covered
Email and SMS strategy · Automated flows (welcome, browse and cart abandonment, post-purchase, win-back) · Campaign calendar · Segmentation · Loyalty and referral programs · Subscriptions · Klaviyo and similar platforms
How Ralph approaches retention
- Measure. Repeat purchase rate, time between orders, revenue by flow and campaign, and list health.
- Prioritize. Fix the flows that leak the most revenue first, then build the campaign rhythm.
- Place. A retention agency or freelance specialist matched to your list size, platform and budget.
- Oversee. Monthly checks on what email and SMS add to revenue, not just open rates.
Retention agency or freelance specialist?
| Freelance email and SMS specialist | Retention agency | |
|---|---|---|
| Best when | Smaller list, core flows and a few campaigns a month | Larger list, full campaign calendar, design and SMS |
| Watch out for | Design capacity and the holiday crunch | Template-heavy work and long contracts |
Platform costs, such as Klaviyo's subscription, are separate from the partner's fee.
Questions to ask a retention agency before you sign
- How will you measure what email and SMS add, beyond the revenue the platform claims?
- Which flows would you fix first in our account, and why?
- Who designs the emails, and how many campaigns a month does the fee cover?
- Do we keep ownership of the Klaviyo account, templates and list?
- How do you plan for the November and December peak?
What you get
- A clear picture of how much revenue repeat customers bring in today
- A prioritized list of flows and campaigns to fix or build
- The right agency or specialist for your list and budget

Questions about retention marketing
What is retention marketing?
Retention marketing is everything that brings existing customers back: email, SMS, loyalty, subscriptions and the post-purchase experience. Its job is to raise repeat purchase rate and customer lifetime value, so growth doesn't depend only on paid acquisition.
Do I need a Klaviyo agency?
Not always. If your flows are solid and you send a few campaigns a month, a skilled freelancer can be enough. If you need a full calendar, design and SMS at scale, an agency usually makes more sense.
How soon does retention work show results?
Fixing broken flows can show up in revenue within weeks. Building a loyal customer base takes longer and is measured over months.
Does Connectwright run the email program?
No. Ralph sets the plan, places the right partner and checks their work.
