Resend → DV360 · Conversion tracking
Connecting Resend to Display & Video 360
Resend is modern developer email where templates live in your codebase, which makes sends easy to ship and equally easy to ship without anyone measuring them. DV360 shares Google's identity graph with Google Ads but not its conversion plumbing, which catches out advertisers who assume a conversion set up in one is visible in the other. The join between them succeeds or fails on one thing: whether the Floodlight activity, not a click identifier reaches the Resend message before the conversion happens, because DV360 can only match a conversion it can tie back to a click it recognizes.

Why this join usually fails
The Floodlight activity, not a click identifier never reaches Resend
The single most common cause. No session, and the send is triggered by application logic that changes on the normal deploy cadence.
Email changes shipping invisibly with deploys
When templates are code, they change without a campaign calendar entry. A conversion rate shift gets attributed to media, creative or seasonality, and the actual cause was a reworded subject line in last Tuesday's release.
Assuming Google Ads conversions appear in DV360
They do not. They are separate systems with separate configuration, and an advertiser running both frequently discovers months in that DV360 has been optimizing toward a Floodlight nobody checked, or toward nothing at all.
Nothing reconciles afterwards
An upload that succeeds is not an upload that matched. Campaign Manager reports Floodlight activity counts directly. Check those, not the DV360 campaign view, and compare against your own order count for the same window.
Architecture
How Resend and DV360 actually connect
Two systems that know nothing about each other. Everything below exists to give them one shared reference.
Step 1
Resend holds the truth
Templates in code means email changes ride along with deploys. A revenue change the week of a release may be the email, and nothing in the marketing stack will show that.
Step 2
Display & Video 360 needs a click to match
DV360 needs the Floodlight activity to fire, or an offline conversion uploaded against it. It also needs the counting method — counter or sales, unique or per-session — set deliberately, because the default is frequently wrong for what you are measuring.
Step 3
The identifier is the bridge
The Floodlight activity, not a click identifier, captured at the visit and carried into the Resend message. Without it there is nothing to join on and no tool fixes that.
Step 4
The event source decides reliability
Send orders, with the email template version attached where a send preceded the purchase.
Step 5
Deduplication at the destination
Floodlight's counting method is the deduplication rule. A counter activity set to count every fire will record repeat page views as conversions, which is the single most common misconfiguration in the product.
Diagnose it honestly
Working vs. broken, side by side
Both states look identical from the DV360 dashboard, which is why this runs for months before anyone notices.
Normal — not a fault
The Floodlight activity, not a click identifier present on the message
Visible on the record itself in Resend, not merely captured somewhere on the site.
Sent from your order system
Server-side, so it does not depend on the customer's browser still being there.
Deduplicated correctly
Floodlight's counting method is the deduplication rule. A counter activity set to count every fire will record repeat page views as conversions, which is the single most common misconfiguration in the product.
Reconciles with the source
DV360's count and Resend's records agree within a few percent over a closed window.
Actually broken
The Floodlight activity, not a click identifier missing on most records
No session, and the send is triggered by application logic that changes on the normal deploy cadence.
Sent from the browser
Anyone who closes the tab, blocks the script or converts without a page load is invisible. When templates are code, they change without a campaign calendar entry. A conversion rate shift gets attributed to media, creative or seasonality, and the actual cause was a reworded subject line in last Tuesday's release.
Counted twice, or not at all
They do not. They are separate systems with separate configuration, and an advertiser running both frequently discovers months in that DV360 has been optimizing toward a Floodlight nobody checked, or toward nothing at all.
Nobody has reconciled it
The dashboard shows a number and no one has compared it to Resend. 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 messages carrying the Floodlight activity, not a click identifier
The ceiling on everything else. Do this before debugging anything downstream.
- 2
Follow one real conversion end to end
From the ad click through Resend and into DV360.
- 3
Check the deploy log before diagnosing an unexplained conversion change
Cheap to check and it explains a genuine share of otherwise mysterious movements.
- 4
Open the Floodlight configuration and read the counting method
Counter versus sales, unique versus every fire. It takes a minute and it explains most inflated DV360 conversion counts.
- 5
Read the match rate, not the success message
Campaign Manager reports Floodlight activity counts directly. Check those, not the DV360 campaign view, and compare against your own order count for the same window.
Source-of-truth validation
How it gets proven
Against Resend's own records, not against either platform's dashboard.
- The Floodlight activity, not a click identifier confirmed present on a live message.
- A real conversion followed from click through Resend to DV360.
- Floodlight conversion counts reconciled against your own order records, with the counting method documented.
- Orders reconciled against imported conversions, with template versions recorded in the timeline.
- 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 DV360 already reports conversions that reconcile against Resend'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 messages and count how many carry the Floodlight activity, not a click identifier. Ten minutes, free, and it tells you whether any of this is worth doing.
- If your emails rarely change, the versioning discipline costs more than it returns.
- If you only run Google Ads, you do not need Floodlight at all and setting it up adds a second conversion system to keep in sync.
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 Resend → DV360 (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.

Got questions?
The honestanswers.
No buzzwords, no upsell. If we don’t know, we say so.
01Why aren't my Resend conversions showing in DV360?
Almost always because the Floodlight activity, not a click identifier never reached the Resend message. No session, and the send is triggered by application logic that changes on the normal deploy cadence. Measure coverage before debugging the dispatch.
02What identifier does DV360 need?
DV360 attributes through Floodlight rather than through gclid. Floodlight is Campaign Manager's conversion counter, it has its own configuration and its own attribution model, and a conversion action built in Google Ads does not exist in it. Two Google products, two conversion systems, one very common and expensive assumption.
03Where should the event come from?
Your order system. Send orders, with the email template version attached where a send preceded the purchase.
04How do I know it worked?
Campaign Manager reports Floodlight activity counts directly. Check those, not the DV360 campaign view, and compare against your own order count for the same window.
