We read what your brand actually emails, and tell you what to fix.
Synapse Retention is a Klaviyo email and SMS practice for Shopify brands. We join your list like a new customer, read your welcome and cart flows as they arrive, and show you exactly what to change. The teardown is free.
Found in live flows
Observations from live welcome flows we’ve subscribed to. Brands anonymised.
| In the flow | Subject line | Inside the email | Result |
|---|---|---|---|
| Welcome email 3 | Promises 15% off | The code inside is 10% | Doesn’t match |
| Welcome sequence | Four emails | Four different discount values in three days | Four answers to one question |
| Day four | “24 HOURS ONLY” offer | The same code, still being sent, beside a second 20% code | The deadline wasn’t one |
| Welcome email 1 | “Your discount inside” | A bare code, no value stated anywhere | The subscriber can’t tell what they got |
| Day two | Two emails, 12 seconds apart | One about protein, one about an app | Two streams colliding |
How a teardown works
A teardown starts where your customers start: on your storefront, with an email address and a checkout left half-finished.
-
We subscribe
We join your list from your own site, the way a new customer would, and start a real checkout to trigger your cart flow.
-
We read your flows
Every email and text is logged as it lands: when it arrived, what it says, what it offers and what it asks for.
-
We show you what’s missing
You get the findings row by row, next to what other brands we’ve read send at the same moment.
-
We rebuild it
If you want us to, we rebuild the flows in your Klaviyo account, starting with the fixes that matter most.
Measured against real brands, not guesswork
Most retention advice is an opinion about best practice. A teardown is a record of what your brand sent, when it sent it, and what other brands send at the same point. So far we’ve read supplement brands most closely. Every recommendation points at something in your flows.
| Question | The usual audit | A Synapse teardown |
|---|---|---|
| Where it starts | A login to your Klaviyo account and a discovery call | Your storefront and inbox, the way a new customer meets them |
| What it’s based on | General email best practice | The emails and texts your brand actually sent, logged as they arrived |
| Who you’re compared with | Ecommerce brands in general | Live flows from brands we’ve subscribed to, though so far we’ve read supplement brands most closely |
| What you get | A list of recommendations | Findings tied to a specific message and moment, with the fix for each |
Where we do our best work
Shopify brands on Klaviyo doing roughly $1M–20M, with a flow programme already running.
A good fit if you
- Sell on Shopify
- Do roughly $1M–20M a year
- Have a flow programme running on Klaviyo
If you’re earlier than that, get in touch anyway — we’ll tell you honestly whether a teardown would help yet.
