Start With Once Per Week
For most businesses, sending one email per week is a strong starting point.
It keeps you visible without overwhelming subscribers.
From there, you can adjust based on engagement data.
Let Engagement Guide You
Instead of guessing, monitor:
- Open rates
- Click through rates
- Unsubscribe rates
- Spam complaints
If engagement drops and unsubscribes increase, you may be sending too often.
If engagement is strong and consistent, you may be able to increase frequency.
Match Frequency to Business Type
Different businesses require different rhythms.
- Ecommerce brands often send 2 to 5 emails per week
- SaaS companies often send 1 to 2 per week
- B2B services may send 2 to 4 per month
The key is aligning frequency with buying behavior and content value.
Prioritize Value Over Volume
Sending more emails only works if each one delivers value.
Ask yourself:
- Does this email help, inform, or solve a problem?
- Would I open this if I were the subscriber?
If the answer is no, reconsider sending it.
Segment High and Low Engagement Users
Highly engaged subscribers can tolerate more frequent emails.
Less engaged subscribers may need fewer messages or re engagement campaigns.
Segmenting by activity allows you to increase volume without increasing unsubscribes.
Test and Adjust
The best approach is controlled testing.
Try:
- Increasing frequency for a small segment
- Reducing frequency for inactive users
- Comparing revenue per subscriber at different sending levels
Data will show you your optimal cadence.
Final Thoughts
There is no perfect number.
Consistency, relevance, and monitoring engagement matter more than arbitrary rules.
Start with a sustainable schedule, track performance, and adjust based on real results.
