Who else sends from these IPs and 93 more.
The IPs, by how much of this mail each carried 48 of ~93 IPs seen. Klaviyo assigns a different IP per send, so this is the set drawn from, not an address. 170.203.20.19 carried 5% of what we saw, well above the 2% an even rotation would give it.
Sending over time Stable in our sample: the same 48 addresses from first to last sighting, 26 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.
