ReConvert → Customer.io · Conversion tracking
Connecting ReConvert to Customer.io
ReConvert customises the thank-you page, which used to be where conversion tracking lived — so the same surface now serves upsells and no longer serves your tags. Customer.io triggers messages from behaviour, which means an event you send is not recorded — it is acted on, usually within seconds, by sending something to a real person. The join between them succeeds or fails on one thing: whether the person identifier you assign reaches the ReConvert thank-you page order before the conversion happens, because Customer.io can only match a conversion it can tie back to a click it recognizes.

Why this join usually fails
The person identifier you assign never reaches ReConvert
The single most common cause. Any tracking that depended on the order status page is gone, and post-purchase offers add revenue after the fact.
The thank-you page repurposed from measurement to merchandising
Stores that used it for both now have upsells working and tracking silently dead. The revenue looks fine in Shopify and terrible in the ad platform, and the two facts are rarely connected.
A test event sending a real email
Because campaigns evaluate on arrival, there is no safe place to test in production. A malformed purchase event fired during development against a live workspace will send a real order confirmation to a real person, and that cannot be recalled.
Nothing reconciles afterwards
An upload that succeeds is not an upload that matched. Customer.io shows the event and the resulting campaign activity on the person's timeline. Check what the event triggered, not just that it arrived.
Architecture
How ReConvert and Customer.io actually connect
Two systems that know nothing about each other. Everything below exists to give them one shared reference.
Step 1
ReConvert holds the truth
The thank-you page is now an extension surface. Apps can place blocks on it; arbitrary scripts cannot run there. That distinction is what broke a large number of conversion setups.
Step 2
Customer.io needs a click to match
Customer.io needs the person identifier, the event name and any attributes the campaign conditions reference. An event whose attributes are missing will still trigger a campaign, which may then send a message with an empty placeholder in it.
Step 3
The identifier is the bridge
The person identifier you assign, captured at the visit and carried into the ReConvert thank-you page order. Without it there is nothing to join on and no tool fixes that.
Step 4
The event source decides reliability
Send final order totals server-side, including any thank-you-page upsell accepted.
Step 5
Deduplication at the destination
Customer.io does not deduplicate events. A purchase sent twice can enter a workflow twice and send two emails, and unlike a reporting duplicate the customer sees this one.
Diagnose it honestly
Working vs. broken, side by side
Both states look identical from the Customer.io dashboard, which is why this runs for months before anyone notices.
Normal — not a fault
The person identifier you assign present on the order
Visible on the record itself in ReConvert, not merely captured somewhere on the site.
Sent from the Shopify order webhook
Server-side, so it does not depend on the customer's browser still being there.
Deduplicated correctly
Customer.io does not deduplicate events. A purchase sent twice can enter a workflow twice and send two emails, and unlike a reporting duplicate the customer sees this one.
Reconciles with the source
Customer.io's count and ReConvert's records agree within a few percent over a closed window.
Actually broken
The person identifier you assign missing on most records
Any tracking that depended on the order status page is gone, and post-purchase offers add revenue after the fact.
Sent from the browser
Anyone who closes the tab, blocks the script or converts without a page load is invisible. Stores that used it for both now have upsells working and tracking silently dead. The revenue looks fine in Shopify and terrible in the ad platform, and the two facts are rarely connected.
Counted twice, or not at all
Because campaigns evaluate on arrival, there is no safe place to test in production. A malformed purchase event fired during development against a live workspace will send a real order confirmation to a real person, and that cannot be recalled.
Nobody has reconciled it
The dashboard shows a number and no one has compared it to ReConvert. A wrong number that nobody checks is indistinguishable from a right one.
Diagnostic sequence
Diagnostic order
Each step rules out a class of cause. Run them in order and the last one usually has a single explanation standing.
- 1
Count orders carrying the person identifier you assign
The ceiling on everything else. Do this before debugging anything downstream.
- 2
Follow one real conversion end to end
From the ad click through ReConvert and into Customer.io.
- 3
Check whether any conversion tag still depends on the order status page
If it does, it is either already dead or on a deadline, and the fix is the same either way.
- 4
Confirm which workspace you are writing to before sending anything
Environment separation is the whole safety mechanism in behaviour-triggered tools, and it is the thing most often skipped.
- 5
Read the match rate, not the success message
Customer.io shows the event and the resulting campaign activity on the person's timeline. Check what the event triggered, not just that it arrived.
Source-of-truth validation
How it gets proven
Against ReConvert's own records, not against either platform's dashboard.
- The person identifier you assign confirmed present on a live order.
- A real conversion followed from click through ReConvert to Customer.io.
- Events confirmed on person profiles with the triggered campaign activity verified, in a test workspace before production.
- Orders reconciled from the webhook against imported conversions with no page dependency.
- Reconciled over a fully closed window, matched per record rather than on totals.
- Re-checked 30 days later.
Straight talk
When you don't need this
Worth reading before paying anyone, including us.
- If Customer.io already reports conversions that reconcile against ReConvert's records within a few percent, this join is working and there is nothing to buy.
- Measure identifier coverage yourself first — pull your last hundred orders and count how many carry the person identifier you assign. Ten minutes, free, and it tells you whether any of this is worth doing.
- Server-side senders were unaffected by the whole migration, which is the strongest practical argument for it.
- If your messaging is scheduled rather than behavioural, a simpler email platform does the job and removes the whole class of accidental-send risk.
Who this is for
Honest about who we’re a fit for.
We don’t take every project. Here’s how to tell if we’re right for you.
You’re a great fit if…
- You run ReConvert → Customer.io (or are migrating to it)
- You spend $5K+/month on paid ads (Meta, Google, TikTok, Microsoft, LinkedIn)
- Your reported ROAS doesn’t match what your bank account is saying
- You want to own your tracking stack — no monthly SaaS fees forever
- You have 2–4 days to do this once and never think about it again
Skip us if…
- You spend less than $500/month on paid ads (browser pixel is fine)
- You want a SaaS dashboard with monthly fees forever (Triple Whale, Hyros)
- You need attribution modeling — we fix the data foundation, not multi-touch reports
- You want a 6-month enterprise consulting engagement (we ship in 4 days)
- You expect us to manage your ad accounts (we don’t — that’s a different service)
If you’re still unsure,book the call anyway— we’ll tell you straight whether we can help.
What working looks like
The person identifier you assign on every order
Server-sideCaptured before the conversion and stored where it survives.
Conversions arriving in Customer.io
8+ EMQThe event lands on the person, evaluates against every campaign trigger and segment condition, and may send immediately.
Reconciled against the source
DedupedReConvert's own records are the reference, not either dashboard.
What gets built
Identifier capture into ReConvert
Move the conversion to the order webhook and treat the thank-you page as a merchandising surface rather than a measurement one.
Event source: the Shopify order webhook
Send final order totals server-side, including any thank-you-page upsell accepted.
Dispatch to Customer.io
The Customer.io Track API, posted server-side from your order or product system with the person identifier and event attributes.
Reversals where they exist
Refunds reverse.
Pick the package that fits your ad spend
Fixed-fee, no surprises. If your ad spend is meaningful,server-side tracking is what we recommend— it’s the only setup that survives iOS, Safari ITP and ad blockers.

Got questions?
The honestanswers.
No buzzwords, no upsell. If we don’t know, we say so.
01Why aren't my ReConvert conversions showing in Customer.io?
Almost always because the person identifier you assign never reached the ReConvert thank-you page order. Any tracking that depended on the order status page is gone, and post-purchase offers add revenue after the fact. Measure coverage before debugging the dispatch.
02What identifier does Customer.io need?
Customer.io identifies people by an ID you control, with email as a common choice. Anonymous events can be sent and later merged, but a mismatch creates a second profile — and a second profile means a second copy of every campaign that person is enrolled in.
03Where should the event come from?
The Shopify order webhook. Send final order totals server-side, including any thank-you-page upsell accepted.
04How do I know it worked?
Customer.io shows the event and the resulting campaign activity on the person's timeline. Check what the event triggered, not just that it arrived.
