Is Email Warmup Just a Bullshit Echo Chamber? Where’s the Real Data?

I’ve seen endless talk about email warmup being essential, but where’s the evidence? I’ve asked countless “experts” for split tests or hard data—nobody delivers. Everyone seems to be parroting the same advice without a shred of proof.

If you’ve run split tests and have actual stats, post them here. I’m tired of the baseless claims. Does warming up an inbox and domain really improve deliverability, or are we all just wasting time? No fluff—show me the real numbers, or stop acting like a warmup guru.

Bring facts, not feelings.

Edit:

lol the astroturfers are in pedaling their BS products. Careful those reading the comments.
