Does “warming” mean sending to everyone slowly?

Myth: Warmup is just reducing speed to your full list.

Reality: Warmup is about audience selection, not just volume.

Correct warmup approach:

Start with most engaged users only

Gradually increase volume

Expand to less-engaged over time

Never include high-risk segments

Why this matters:

Engaged users generate positive signals

Unengaged users generate negative signals

Slow volume to bad list = slow failure

Warmup success requires:

Segment selection (engaged first)

Volume pacing (gradual increase)

Monitoring (adjust based on metrics)

Start with best customers, not slow delivery to everyone.
