This measures how many brand-new contacts you add per day to this number’s messaging universe.
- Controlled growth: up to 200–300 new contacts/day
- Aggressive: 300–500 new contacts/day
- High risk: 500+ new contacts/day, especially on new numbers
#Why it matters
Huge spikes in new contacts—especially if they’re all being messaged quickly—look like list buying, scraping, or other non-consensual behavior.
#How to improve this metric
- Spread acquisition over time instead of uploading and hitting a giant list on day one
- Use clear opt-ins so people know they’ll receive messages from you
- Warm up new numbers with smaller, higher-quality lists before scaling
