Maintaining consistent sending frequency helps protect which aspect?

• A. Open rate
• B. Click-through rate
• C. Sender reputation
• D. List growth

Answer: (C)

Maintaining a steady sending cadence protects your sender reputation. Sender reputation is the score ESPs use to decide whether your emails land in the inbox or get filtered to spam. It’s built from factors like bounce rates, complaint rates, engagement, and especially sending patterns. When you email on a predictable schedule, you avoid sudden bursts or gaps that could look suspicious to receivers and spam filters. That consistency helps keep engagement healthy and keeps complaint and bounce rates low, which strengthens your reputation with mail providers.

Open rate and click-through rate can fluctuate based on whether messages actually reach the inbox, so they’re influenced by deliverability, which is in turn affected by reputation. List growth also depends on deliverability and subscriber engagement, but the key protective effect of a consistent cadence is preserving the sender’s reputation, ensuring better inbox placement over time.
