Most subscription stores have similar problems. High Churn rate before 90 days. This causes the LTV to stay low. And reduces the LTV/CAC metric ( which is one of the most important metrics for any brand's long-term success )

We fixed that problem for one supplement brand using email and SMS. Here’s the full story — broken down so anyone can follow.

The Problem Most Subscription Brands Face 

• Customers buy one bottle/stash of gummies/pills/powder and disappear • No strong post-purchase emails or texts 

• Repeat rate stays low 

• LTV never grows 

• Profit stays stuck in “just okay” mode

Even worse, most sub-brands try to lower their target ROAS, hoping they recover it in the long run.

But their take rate? 20%

Average churn period? Less than 60 Days

On paper, it looks good, but profit margins are lower than they expected.

Here’s Exactly What We Did:

We built 2 dead-simple Klaviyo flows sent only to people who hadn’t subscribed yet.

(This screenshot shows the exact setup of both flows)

Flow no. 1: The Non-Subs → Subs Flow [ AKA Subscription Flow ] This flow runs automatically within 15 days of the customer receiving their product. • Sets realistic expectations (supplements aren’t magical pills that give sudden changes) • Emphasizes the power of consistency • Frames subscription as “Receive the remedy without the hassle of manually re-ordering + save X%” • Uses 5-6 easy email sequences

The Predictive Analysis Flow

This one is smarter — it triggers when Klaviyo predicts the customer will need their next order in the next 8-10 days.

 • Only for non-subscribers 

• Uses the exact same consistency messaging 

• In the example: $659.35 total CLV with expected date of next order being april 13 , &  We also added SMS on top so they actually open and reply fast.

Here’s What Happened to the Numbers After the flows ran:

 • LTV jumped 3.37% to $83.70 

• Total revenue up 64.55% 

• Profit exploded by 79.56%

Also note that the NCPA has increased by 19%  - Even with this, the LTV / CPA metric is increasing.

Before the flows: lower numbers. After: clean jump to $83.70.

More people started subscribing → each customer spends way more over time.

The extra money goes straight to profit (no new ad costs).  The first 30 days decide if customers come back.

We won that window, so the value showed up fast most of it in the first 90 days.

Even a 5% LTV Lift = 25–45% More Profit in 3 Months Why? 

• Acq Costs costs don’t rise 

• Extra money drops straight to the bottom line 

• Subscription value hits early and keeps growing.

Here’s What You Can Do Next: Set up these 2 non-subscriber flows (Non-Subs → Subs + Predictive) Use simple “consistency” messaging in the first 30 days Add SMS for urgency Check your LTV every month in Klaviyo.
