From Vinson · 25 September 2026 · for the designer and Gavin
The free trial flow gets rebuilt as three short emails, one button each, in the V2 design. It replaces IB // Stripe Free Trial Activated -- (SDXETb) and the five-email plan in the handover.
Design file: Figma, Emails page. V1 is the red column, V2 the green. Build in V2.

| Ran it at any point in the trial | 61% | 40% |

| Paid, ran it once | 32% | 14% (20 of 142) |

Source: Stripe subscriptions matched to app sessions, 25 Sep. A "run" is a session the user starts in the app.
How to read it. Since the trial left the default checkout on 5 August, trials come only from the "Try for free" widget and /try4free, so there are fewer of them and they convert at about half the old rate. The recent numbers are too small to prove much on their own. The larger earlier sample shows an association between more runs and higher conversion. It does not prove that another run causes payment.
The current emails, last 90 days:
| Status | Sent | Opened | Clicked | |
|---|---|---|---|---|
| 1 · "Welcome to a faster, more powerful PC" | Live | 4,688 | 35% | 2.7% |
| 2 · "Check Out Your Hypertune Free Trial Features" | Draft now | 2,383 | 19% | 0.04% |
| 3 · "IMPORTANT! Your Free Trial ends soon" | Draft now | 2,357 | 35% | 2.8% |
| # | Sends | Job | Button | Goes to | Smart Sending |
|---|---|---|---|---|---|
| 1 | Immediately | First Boost | Download Hypertune | Installer | Off |
| 2 | Day 2 | Run it for the first or second time | Open Hypertune / Download Hypertune / Run a benchmark | The app / Installer | On |
| 3 | Day 6, 24 hours before the scheduled charge | Know what happens next | Manage my plan | Account plan page | Off |
Smart Sending stays off for email 1 because the account-created email goes out minutes earlier and Smart Sending would skip the trial welcome. Keep it off for email 3 while the notice is built. Once Klaviyo approves the message as transactional, Smart Sending does not apply to it.

Hi there,
>
Your 7-day trial has started. Start with one thing today: run your first Boost.
>
1. Download and install Hypertune.
2. Let it scan your PC.
3. Press Boost, then launch your game.

Hypertune creates an automatic restore point, and you can revert its changes in one click.

Button: Download Hypertune
Link: the direct installer link from Kamil; if there isn't one that works from an email, the page where signed-in users download the app. Not the tutorial. Add the tags from the rules.
Image: none needed. If the design team adds one, it's the Boost screen, linked to the same place.
Sends: day 2. Once Kamil sends optimizer runs to Klaviyo and confirms a usable app link, split it: people who haven't run Hypertune yet get version A, everyone else gets version B. Until then, use the neutral fallback. Do not tell everyone they have not run it.
Fallback · run status unknown
Subject: Try Hypertune before your trial ends
Preview text: There is still time for a Boost.
Headline: Try Hypertune before your trial ends
Body:
Hi there,

Your trial ends on {{ trial end date }}. Open Hypertune and press Boost before then. If it is not installed yet, the button takes you to the download.
>
Austin
Button: Open Hypertune
Link: the app link if Kamil confirms one. Otherwise change the button to Download Hypertune and use the same download destination as email 1.
Version A · not run yet
Subject: Did your first Boost go through?
Preview text: If not, it takes two minutes.
Headline: Try it before your trial ends
Body:
Hi there,
>
You haven't run Hypertune yet. Install it, let it scan and press Boost. Your trial ends on {{ trial end date }}, so there is still time to see what it does on your PC.
>
Austin
Button: Download Hypertune · same link as email 1.
Version B · already run it
Subject: See what changed on your PC
Preview text: Run a benchmark before your next game.
Headline: See what changed
Body:
Hi there,
>
You've run your first Boost. Now open the Benchmark tab and run one before your next game, so you can see the difference on your own hardware.
>
Austin
Button: Run a benchmark
Link: a link that opens the app on the Benchmark tab (Kamil to confirm). Keep the neutral fallback until this destination exists.
Subject: Your trial ends on {{ trial end date }}
Preview text: Here's what happens next.
Headline: Your trial ends on {{ trial end date }}
Body:
Hi there,
>
Your free trial ends on {{ trial end date }}. Your paid plan is scheduled to start at {{ plan price }} {{ billed monthly or yearly }}.

The date and price come from profile properties Kamil sends. Never type them in. Regional prices differ and the yearly offer changes around 30 September.
Stripe First Free Trial Activated.utm_source=klaviyo&utm_medium=email&utm_campaign=trial&utm_content=1 (then 2U for the neutral fallback, 2A, 2B and 3).| What | For |
|---|---|
| A direct installer link that works from an email, or confirmation there isn't one | Emails 1 and 2A |
| Whether the app can be opened from a link, and on which tab | Email 2 fallback and 2B |
An optimizer-run event sent to Klaviyo (for example Ran Optimizer, with the date) | The email 2 split |
| Trial end date, plan price and billing period on each trial user's profile | Email 3 |
Email 1 can go live once the installer destination is ready. Email 2 uses the neutral fallback until the run event and app destination arrive, then changes to the A/B split. Email 3 waits for the trial date, price and billing-period properties.
Email 3's button: "Manage my plan" (recommended, and the honest version), or a "switch to yearly and save" offer. The offer may earn more clicks, but it would be the only email in the flow that sells.
| Measure | Baseline, trials since 5 August | Read after |
|---|---|---|
| Trials that run Hypertune in the first 24 hours | 40% (157 of 395) | 60 days (about 600 trials) |
| Trials that run it twice or more | 4% (16 of 395) | 60 days |
| Trial to paid | 15% (59 of 395) | 60 days |
| Email 1 click rate | 2.7% | 30 days |
At about 300 trials a month, anything under 60 days is noise. Judge it on the first two rows: they move first, and they are what the emails are for.
