Finding Your Perfect Email Cadence

Why Email Frequency Matters

Sending emails too often can lead to “list fatigue,” where your subscribers become overwhelmed and start to ignore, delete, or—worst of all—unsubscribe from your communications. On the other hand, sending emails too infrequently can cause your audience to forget about you, leading to missed revenue opportunities. The key is to find the perfect balance that maximizes engagement and revenue while minimizing list churn.

The Law of Diminishing Returns

This calculator is based on the principle of diminishing returns. Initially, sending more emails will likely increase your total revenue. However, at a certain point, the revenue lost from unsubscribes will outweigh the gains from sending one more email. This tool helps you identify that “peak” frequency where your net revenue is at its highest.

  • Low Frequency: You’re likely leaving money on the table.
  • Optimal Frequency: The sweet spot where revenue is maximized.
  • High Frequency: You’re losing more money from unsubscribes than you’re gaining from the extra emails.
