Subscription Retention Agency

Short answer

A subscription retention agency keeps subscribers paying for longer. At Email Kong that means running Klaviyo and the subscription app as one program: the cancel flow, failed payment recovery, winback after a cancel and the offers that turn one-time buyers into subscribers. We are a Klaviyo Platinum Partner and an official Loop Subscriptions partner.

What a subscription retention agency does

It looks after everything that happens after someone subscribes, inside your email platform and inside your subscription app. For our brands that is Klaviyo for email and SMS, and Loop for the subscription itself.

Here is how the work splits, and what we watch for each part:

JobWhere it is builtWhat we measure
Cancel flow: benefits page, cancel reasons, an offer per reasonLoop customer portalSaves per reason, per offer
Failed payment recovery: retries, card-update messagesLoop recovery strategies, plus Klaviyo SMS and emailRecovery rate by failure type, revenue recovered
Winback after a cancelLoop instant winback offer, plus a Klaviyo flowRestarted subscriptions
Turning one-time buyers into subscribersKlaviyo post-purchase and reorder flowsShare of first-time buyers who subscribe
Upcoming order and portal emailsLoop notifications, restyled to your brandSkips and frequency changes vs cancels
Add-ons at renewalLoop upsell profiles and volume discountsAdd-on revenue per renewal

The campaigns and the welcome and abandonment flows still matter, and we run those too. The subscription work sits on top.

Why subscription churn needs the app and Klaviyo run together

Most subscribers are lost at 2 points email cannot fix on its own: the cancel screen in the portal, and the card that fails at renewal. Both live in the subscription app, so whoever runs your retention needs access to it.

Subscription retention agency map: where subscribers are lost, from orders 1 to 3 to winback, and what Loop and Klaviyo do

The vendor numbers show where the losses sit. Eightx, a subscription agency, reports that 60-70% of subscribers are lost between order 1 and order 3, and that failed payments cause 30-40% of subscription churn. Treat those as directional, since they come from one firm's client data.

If your Klaviyo agency has no login to Loop, the cancel flow usually stays on its default settings, the payment retries run with default timing, and nobody connects the 2. When we searched for subscription agencies in October 2026, the ones we found mostly sold Recharge setup and development. We run the retention side every month, in both tools.

Across the subscription brands we run on Loop, the #1 cancel reason is "I have enough or too much product", at about 23% of cancel attempts in the last 90 days. That reason is answered with a skip, a slower frequency or a pause, which are all set up inside the subscription app, so an email-only setup cannot change it.

The order we work in on a new subscription account

We fix the leaks closest to revenue first, then build the flows that grow subscriber lifetime. On most accounts the order looks like this:

  1. Failed payments. These subscribers did not choose to leave. We split the retry ladder by failure reason, add a one-click card-update link to SMS and email, and end on a pause so the subscription can restart.
  2. The cancel flow. We rewrite the cancel reasons in the words your customers use, then give each reason one fitting option: skip, swap, pause, a change of frequency or a single discount.
  3. Orders 1 to 3. Subscriber welcome emails, a clear reminder before the first renewal, and how-to-use content so the product gets used before the second charge.
  4. Winback. An instant offer on the cancel screen, and a short Klaviyo flow after it.
  5. Subscribe offers. Post-purchase and reorder flows that move one-time buyers onto a subscription, with subscribers kept out of the reorder reminders.

Before any of this we check that Loop events are really arriving in Klaviyo. An integration can stay connected in Klaviyo long after a brand stopped selling subscriptions, so we go by live event volume.

Subscription niches we work in

Most of our subscription brands sell something that runs out: pet products, supplements and women's health, skincare and oral care. Each has a different buying cycle, which changes how the cancel flow and the reorder timing should work.

  • Pet. Pet food and supplements have one of the biggest gaps between subscribers and one-time buyers. Eightx puts the gap in order count at about 4.6x for pet food. A cancel reason like "my pet doesn't use it" needs a swap or a how-to, and a discount will not fix it.
  • Supplements and women's health. Recharge's Subscription Trend Report 2026 names health and wellness as the largest subscription category, at about 11.2M active subscribers, with supplements about half of it. Eightx puts typical supplement churn at 5-8% a month.
  • Skincare. Subscribers often cancel because they have too much product, so skip and a slower cadence save more than a discount does.

We are building separate pages for each of these niches with examples from our own accounts.

Which subscription apps we work with

Most of our subscription brands run on Loop, and we are an official Loop partner. 6 brands currently run their subscriptions on Loop with us.

If you are on Recharge, Skio or Appstle, we can run the Klaviyo side and help you decide whether moving to Loop is worth it. If you are on Skio and weighing your options after the Recharge deal, read our Skio to Loop guide.

EK proof

These are results from subscription brands we run today, measured as Klaviyo's share of total store revenue, so you can compare them with your own store:

  • Kaori (women's health, subscription): Klaviyo went from 3.3% to 19% of store revenue. Flow revenue grew 17.7x, from $31,358 to $554,913. Email revenue grew 9.5x.
  • Penrose Skin (skincare, subscription): Klaviyo's share of store revenue went from 15.2% to 23.2%. Flow revenue grew 10.5x and email revenue 5.2x.
  • KittySpout (pet, subscription): 46% of store revenue comes from Klaviyo.

Across our Loop brands in the last 90 days there were 20,000+ cancel-flow events and at least 50,000 failed billing attempts. About 1 in 5 people who started canceling gave no reason at all.

We have worked with 140+ brands, mostly DTC brands doing $3M to $50M a year in the US and UK.

Who this is a fit for

We are a fit if subscriptions are a real part of your revenue, you are on Shopify, and you are doing roughly $3M to $50M a year. Below that, Loop's default settings and a solid Klaviyo welcome flow will take you a long way, and our pricing page explains what the jump to an agency costs.

Frequently asked questions

How do I reduce subscription churn on Shopify?

Start with failed payments and the cancel flow, since that is where most subscribers are lost. Set retries by failure reason, send a card-update link by SMS and email, and give each cancel reason one fitting option such as skip, swap or pause.

What is the difference between a subscription retention agency and a Klaviyo agency?

A Klaviyo agency runs your emails and SMS. A subscription retention agency also works inside your subscription app, on the cancel flow, payment retries, winback offers and portal, so the 2 sides are planned together.

Do you work inside Loop or only send emails?

Both. We build and test in the Loop admin (cancel flows, recovery strategies, winback offers, upsell profiles, notification emails) and run the Klaviyo flows that use Loop events.

Can you help if we are on Recharge or Skio?

Yes. We can run the Klaviyo side on any app. If you are thinking of moving to Loop, we plan the move and rebuild the Klaviyo flows that depended on your old app's events.

How soon will we see a change?

Payment recovery and cancel flow changes show within the first billing cycle after they go live, because every renewal and cancel attempt passes through them. Flow and campaign revenue builds over the following months.

What does a subscription retention agency cost?

Most retention agencies charge a monthly retainer. Our Klaviyo agency pricing page lists market ranges, the pricing models and our own packages.
