Why can't I just do this myself?

You can — if you have 80–120 hours to learn server-side GTM, debug iOS dedup edge cases, and stress-test EMQ across every conversion event. We do it in 7–10 days because we've done it 300+ times.

What if it doesn't work?

Two protections: (1) 95% tracking accuracy guarantee — we keep working free until your Meta Match Quality hits 8+. (2) You own the entire stack — server, container, runbook — on your accounts from day one.

Will Apple / Google break this in the future?

1st-party server-side tracking is what survives Apple, Mozilla, and Chrome cookie deprecation. The CAPI / Events API endpoints we use are how Meta, Google, and TikTok publicly committed to keeping the channel open.

What should a retained subscriber be worth?

Contribution margin over your own median tenure. Include box cost and shipping — on a low-price box those frequently consume the whole margin.

Should the discount code be on the conversion?

Yes. Offer depth is the strongest predictor of churn you have, and without it on the record you cannot compare campaigns that ran different offers.

As retained revenue, reported separately. Sending each one as a conversion turns one acquisition into twelve and makes cost per acquisition meaningless.

Subscription boxesIndustry solution

Conversion tracking for subscription boxes, measured in retained subscribers

Subscription boxes live and die on month-three retention, and almost every acquisition decision is made on month-one data. A deep introductory discount produces a signup that looks cheap and a subscriber who cancels after the second box, and the ad account records the win and never the departure. The only figure worth optimising toward is a subscriber who is still paying when the discount ends.

The cheaper the offer, the faster they leave.
03

One acquisition becoming twelve.

Subscription boxes · the fix

Subscription boxes · architecture

The conversion map for subscription box businesses

Five events where only the later ones mean anything.

1
Signup on offer
Cheap, abundant, and weakly predictive.
2
First box shipped
Cost incurred, revenue barely.
3
Second box
The first real retention signal.
4
First full-price payment
5
Month six
Where the cohort's true value becomes visible.

Subscription boxes · diagnose

Where subscription box businesses tracking usually breaks

01
Optimising on signups
It reliably finds people who like free things, and the cost per signup looks excellent throughout.
02
Renewals counted as new conversions
Inflates the count by exactly your retention rate.
03
Lifetime value taken from an industry figure
Your own churn curve says something different and it is usually shorter.
04
Shipping and box cost absent from the value
On a low-price box these can exceed the margin entirely.

FAQ

Subscription boxes questions, answered

Because signup-to-retention differs by a factor of several across offers and channels, and bidding on signups reliably buys the worst of them. Faster learning on the wrong signal is not an advantage.
