The forgotten warm-up service still sending 40 emails a day from the old server is such an easy thing to miss after a migration, and the same-week test to 1,783 people from a second address is a clean way to rule out content. I also appreciate that you said plainly you can't separate the warm-up change from the reply-based giveaway. If you ever test it again, sending the reply campaign from a fresh subdomain first might help isolate which one Gmail responded to.

Thanks for reading it that closely. That warm-up was easy to miss because nothing looked broken on my end. Every message still passed authentication.

The subdomain idea makes sense. I didn't split it because once I'd found the warm-up still sending from a server nobody was reading, the cause was clear enough, and I haven't had a reason to rerun it. Opens from Gmail users were 0.2% in August and about 20% in early October.
