Email Frequency Calculator

Email Frequency Calculator helps you find the sweet spot between sending too many emails (causing fatigue and unsubscribes) and too few (leaving revenue on the table). Enter your audience details, engagement metrics, and goals to get a personalized frequency recommendation with fatigue risk analysis, revenue impact modeling, and a weekly email calendar planner.

Over-sending is the #1 reason people unsubscribe from email lists. Under-sending means missed revenue and fading brand awareness. This tool uses industry benchmarks and engagement modeling to recommend the optimal cadence for your specific situation.

• Optimal frequency recommendation: Personalized suggestion based on your industry, audience type, list size, and current engagement metrics.
• Fatigue risk meter: Visual gauge showing whether your current frequency risks subscriber burnout, with early warning indicators.
• Revenue impact curve: Shows how increasing or decreasing frequency affects estimated revenue and unsubscribe rates.
• Engagement-based segmentation: Different frequency recommendations for highly engaged, moderately engaged, and inactive subscribers.
• Weekly calendar planner: Drag-and-drop style email schedule builder with optimal day suggestions.
• Frequency comparison: Side-by-side analysis of different frequencies (e.g. 2/week vs 4/week) showing trade-offs in revenue, unsubs, and fatigue.

1. Select your industry and audience type: This sets the baseline frequency benchmarks.
2. Enter engagement metrics: Your current open rate, click rate, and unsubscribe rate help calibrate the recommendation.
3. Set your current frequency: How many emails you send per week/month now.
4. View the recommendation: See the suggested frequency, fatigue risk, and revenue impact.
5. Compare frequencies: Use the comparison tab to see trade-offs between different cadences.
6. Plan your week: Use the calendar planner to schedule your sends.

Example 1: SaaS B2B newsletter, 8,000 subscribers, 22% open rate, currently sending 1/week. Recommendation: Increase to 2/week — projected +40% email revenue with minimal fatigue risk.

Example 2: E-commerce store, 45,000 subscribers, 14% open rate, currently sending 5/week. Recommendation: Reduce to 3/week — projected -15% revenue but -60% unsubscribes, net positive for list health.

• Stop guessing your cadence: Data-driven recommendation instead of arbitrary scheduling.
• Prevent subscriber fatigue: Catch over-sending before it damages your list.
• Maximize email revenue: Find the frequency that generates the most revenue without burning out your list.
• Segment intelligently: Different frequencies for different engagement levels.
• Plan ahead: Weekly calendar makes scheduling easy and consistent.
