Who else sends from these IPs and 55 more.
The IPs, by how much of this mail each carried 25 of ~58 IPs seen. Klaviyo assigns a different IP per send, so this is the set drawn from, not an address. 170.203.28.37 carried 12% of what we saw, well above the 4% an even rotation would give it.
Sending over time Stable in our sample: the same 25 addresses from first to last sighting, 6 months.

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.
