This is the sample

A client report is private. This one is public because it is built on kureapp.health, a sender from our open panel, and every figure in it already sits on that company’s directory page. Boxes marked in a paid auditare filled from the client’s own DMARC reports and campaign log; here they show the structure rather than fake the numbers. Price and ordering.

Pool audit: kureapp.health

Prepared from the ipneighbors panel. 386 campaigns observed between 4 Mar 2025 and 28 Jul 2026, across 25 sending addresses.

1 · The verdict

Reassignment signature

The set of addresses behind kureapp.health’s mail turned over around March 2026: 12 addresses we had been seeing stopped appearing and 13 new ones took their place. Entries and exits together are the signature of a Klaviyo pool reassignment; either alone is usually sampling.

In a paid audit

Our panel samples this sender’s campaigns, which is why this paragraph says “around March 2026” and “signature”. Your DMARC reports see every send, so the paid version carries a date and a verdict: reassigned or not, on what day, and what the new set of addresses is.

Coverage of this sample: 25 of ~26 IPs seen.

In a paid audit

This table is complete rather than sampled: aggregate reports from Gmail, Yahoo and Microsoft enumerate every address that carried your mail, with daily counts. For this sender that would mean roughly 26 rows with no estimate attached, and tenancy dated to the day.

3 · The neighbors

This window spans two pools, the one before the move and the one after, so no single sender matches it address for address. The companies below share the most addresses across both; a paid audit splits them into old neighbors and new.

perfectted.comoverlapping59%20 shared
getfussy.comoverlapping56%19 shared
moerie.comoverlapping52%13 shared
jimmyjoy.comoverlapping50%23 shared
yourheights.comoverlapping50%18 shared
colonbroom.comoverlapping49%18 shared
simplemodern.comoverlapping48%24 shared
liquiddeath.comoverlapping48%12 shared

Neighbor names come from the panel in a paid audit too; DMARC shows only your own mail. This is the part no header check can give you, and it improves as the panel grows.

4 · The movement

13 addresses first appeared mid-window and 12 stopped appearing. Entries and exits together are what a pool reassignment looks like; confirming one needs your DMARC reports.

In a paid audit

The confirmed version of this chart: per-day counts on every address, the day the old set stopped carrying your mail and the day the new one started, from reports the mailbox providers send about you specifically.

5 · What went out around the move

In a paid audit · from your campaign log

Klaviyo re-grades senders on engagement, so the campaigns in the fortnight before a move are the evidence that explains it. The report lines your campaign log against the move date: what went out, to which segments, at what volume, as you export it from Klaviyo. This sample cannot show that section. We do not have this sender’s campaign log, and would not publish it if we did.

6 · The verdict in writing

A reassignment is Klaviyo’s grade of your sending, delivered silently. The written verdict does three things: dates the move, names the most plausible cause from your own campaign record, and puts a paragraph in your hands that gets a straight answer from support. The order to check causes in:

A segment gone stale. Engagement decay precedes demotion, and it is the most common cause by a distance.
A volume or frequency jump in the six weeks before the move.
A new list source. One purchased or swept-in segment can outweigh a year of hygiene.

Support ticket, ready to send
Our DMARC reports show the set of IPs carrying our campaigns changed around March 2026 (among others, 168.245.59.73 stopped carrying our mail and 167.89.100.40 began). Please confirm the date of the pool reassignment and which sending pool we are now in.

And what not to spend on: template redesigns and paid warm-up services do not move a sender between shared pools. Engagement does. The report says that in writing so nobody upsells you around it.

7 · Method and what we refuse to claim

From the client’s DMARC reports: the complete address list, daily counts, exact move dates. From the panel: 29months of history on the addresses and the named companies sharing them. From the client’s campaign log: what went out around each move. Each claim in the report carries its source and its coverage.

Not claimed, here or in a paid report: any neighbor’s performance, volume or inbox placement; tier rankings beyond what is measured; and no verdict a panel sample cannot support. A brand that would rather not appear in the panel is removed on request, same day.
