How Often Should You Email Your Customers? Data-Backed Answer

There’s no universal right answer to email frequency — but there is a reliable method for finding your own optimal cadence instead of guessing.

Why ‘Once a Month’ Is Usually Too Rare

Infrequent senders are often forgotten between emails, leading subscribers to mark emails as spam simply because they don’t recognize the sender anymore — some consistency is required to stay recognized.

Why Daily Is Rarely Right Either

Very high frequency works only for content-heavy models (daily news, flash-sale retailers) — for most businesses, it accelerates unsubscribes faster than it drives incremental revenue.

A Reasonable Starting Cadence

Weekly to bi-weekly works well for most small-to-mid businesses — frequent enough to stay top-of-mind, infrequent enough to maintain perceived value per email.

Let Engagement Data Guide Increases

If open and click rates stay healthy as you increase frequency, you likely have room to send more; if unsubscribe rates climb noticeably, pull back.

Segment Frequency by Engagement Level

Highly engaged subscribers can often handle higher frequency than occasional openers — sending everyone the same frequency ignores this natural variation in appetite.
