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.
