Who else sends from these IPs and 60 more.
The IPs, by how much of this mail each carried 41 of ~59 IPs seen. Klaviyo assigns a different IP per send, so this is the set drawn from, not an address. 170.203.28.20 carried 11% of what we saw, well above the 2% an even rotation would give it.
Sending over time No addresses first appeared mid-window and 4 stopped appearing. In a sampled panel that is usually sampling, not movement; the real answer needs your DMARC reports.

How this was measured
Panel mailboxes subscribe to public newsletters. Every message carries the IP that delivered it in its Received: headers, which is how the pairing of brand to IP is established. Nothing here is modelled or inferred.
Published: which IP carried which brand's mail, by day. Not published: how much anyone sends, when exactly, or where their mail landed. Adjacency is a fact about shared infrastructure; performance belongs to the sender.
A brand that would rather not appear here is removed on request, same day.
