How Often To Send Marketing Emails

In This Article▼

One of the most common questions in email marketing: how often should you email your subscribers? The answer isn't one-size-fits-all, but there are proven guidelines to follow.

The Goldilocks Zone

Send too few emails and subscribers forget about you. Send too many and they unsubscribe. Finding the right frequency is about understanding your audience and testing what works.

Chart plotting revenue per subscriber and unsubscribe rate against sends per week. Revenue peaks at three sends and then declines, while unsubscribes keep climbing to 2.4 percent at seven sends — Revenue per subscriber peaks long before unsubscribes do. The shape is illustrative, and the peak in the chart sits at three sends a week only as an example. Where yours lands depends on your industry and your list.

General Guidelines by Industry

E-commerce

Recommended: 3-5 emails per week

E-commerce subscribers expect frequent updates about sales, new products, and promotions. More frequent sending is acceptable as long as content is relevant.

B2B / SaaS

Recommended: 1-2 emails per week

Business audiences prefer quality over quantity. Focus on valuable content, product updates, and educational resources.

Service Businesses

Recommended: 2-4 emails per month

Unless there's urgent news, service businesses can maintain engagement with less frequent but highly relevant emails.

Media / News

Recommended: Daily or multiple times per day

News subscribers sign up expecting frequent updates. Timeliness is the priority.

How to Find Your Optimal Frequency

1. Ask Your Subscribers

Include frequency preferences in your sign-up form, send a survey to existing subscribers, or give them a preference center they can come back to at any time.

Email preference center offering weekly, monthly or only big launches, plus topic checkboxes for new arrivals, sales, style tips and restocks, with an unsubscribe from all link beside the save button — A preference center gives people a way to turn the volume down instead of leaving. Note how much quieter "unsubscribe from all" is than the cadence options above it.

2. Segment by Engagement

Send more frequently to highly engaged subscribers and less to those showing lower interest.

3. A/B Test Frequency

Split your list and test different sending frequencies. Measure engagement and unsubscribe rates over time.

4. Monitor Your Metrics

Watch for changes in open rates, click rates, and unsubscribes as you adjust frequency.

Quality Over Quantity

Regardless of frequency, every email should provide value. A great email once a week beats mediocre emails every day.
