TL;DR: 61% of your customers want to hear from you at least once a week, per Campaign Monitor. Media Shower research shows the best frequency for B2B marketers is at least once a month, and no more than twice a week.

So What: By understanding email marketing frequency, you can ensure your email newsletters are sent out at the correct times and in the right amounts to maximize customer engagement. How often you send newsletters will depend on other factors, such as the size of your audience, the type, and the amount of content you’re sending. 

You want to add value for your subscribers and encourage them to visit your website often. Try to test different times and days and see what works best for your target audience. (Hint: try midweek at midday.)

Email marketing is still the most used marketing strategy globally, with 4.3 billion users in 2022 and forecasted to grow to 4.6 billion by 2025. That’s half the planet’s population!


What’s the Recommended Frequency for Sending Newsletters?

In a study by MarketingSherpa, 86% of subscribers said they would like to receive promotional emails from their preferred brands monthly. This indicates customers are open to more email communication from their favorite businesses, which can be used to drive sales and loyalty.

So, which frequency is best for your business? According to research by Campaign Monitor, newsletters should be “no more than twice a week and at least once a month.” The study also shows us there isn’t much difference in the open rates between any days of the week except for a slight dip on the weekends, as you can see from their graph below:

Day of the week Open Rate Click-Through-Rate Click-to-Open-Rate Unsubscribe rate
Sunday 20.3% 2.1% 10.1% 0.1%
Monday 22.0% 2.3% 10.6% 0.1%
Tuesday 21.8% 2.4% 10.8% 0.1%
Wednesday 21.8% 2.3% 10.7% 0.1%
Thursday 21.7% 2.3% 10.7% 0.1%
Friday 21.6% 2.2% 10.1% 0.1%
Saturday 20.5% 2.1% 10.1% 0.1%


  1. Weekly: This email frequency might be appropriate for companies that want to increase the frequency of their communications with subscribers or for brands that have limited resources and need to focus content efforts on a few select campaigns per month.
  2. Biweekly: This email frequency is best suited for companies who want to send out two monthly emails: one from the prior month’s event or campaign and one specifically designed for this upcoming month’s audience.
  3. Bimonthly: This email frequency might be best suited for companies who want to send one monthly newsletter with news from the prior month’s events or campaigns and new content designed specifically for this upcoming month’s audience.
  4. Monthly: This email frequency might be appropriate for brands that want to engage subscribers with more timely communications or that have large budgets and want to send more frequent updates.
  5. Quarterly: This email frequency is best suited for companies that want to send out one quarterly newsletter that includes all events, campaigns, or marketing promotions from the past three months.

What Factors Should You Consider in Newsletter Frequency?

There are a few key factors to consider:

  • Newsletter purpose and goals: What are you trying to achieve? For example, if you’re in the education industry, you might create a weekly newsletter focusing on learning resources and tips to help teachers and students. (Monthly might not be enough.)

If you’re in the tourism industry, you might opt to create a quarterly email focused on upcoming events related to the region where your company is located. (Daily might be too much.)

  • Your target audience: If you’re in the education industry, the target audience might be parents who read your newsletter after the workday, so a weekly delivery on the weekend might be perfect. 

The target audience for a tourism-related quarterly email might be business owners and travelers who receive it on their smartphones or computers during lunchtime at work.

  • Your open rates and churn: By tracking open rates and churn (read our post on tracking best practices), you can see what’s working for your customers. By watching what your customers do, not just what they say, you can adjust your email newsletter’s send frequency and topics to get better results and improve customer engagement.

Again, you want negative churn (i.e., a positively growing email list where new subscribers outnumber unsubscribes) and an open rate of about 20%.

What’s the Optimal Time to Send Newsletters?

Conventional wisdom says mid-week at mid-day (Eastern time). It’s a great place to begin, but testing to find your optimal time makes sense.

Is your audience made up of techies? Techies tend to be night owls, so that will override conventional wisdom. Are they bankers or insurance underwriters who are much more likely to be on a traditional work schedule? Or are they stay-at-home moms juggling kids, schedules, and online jobs? 

And where in the world are they located, in which time zones?

Here are some tips to help you find the best send time for your newsletters:

  1. Split test: Split testing is a great way to determine the best send time for your newsletters. You can send two versions of your newsletter and compare the results at different times. A good rule of thumb is to use about 12 data points (i.e., three months for a weekly newsletter) to conclude.
  2. Analyze subscribers’ locations and time zones: This can be done using tools like Mailchimp’s Geo tool.
  3. Consider the type of content you’re sending: If your newsletter focuses on a consumer product, consider when your consumers will likely purchase (or think about purchasing) the product.
  4. Consider subscriber goals: Are you increasing conversion rates or reducing churn?
  5. Consider the season: Emails are less likely to get read between Christmas and New Year, along with other major holidays like the 4th of July or Labor Day in the U.S. Best to take a week off.

TL;DR Summary

The right newsletter cadence is somewhere between monthly and twice a week. Monday through Friday work hours are great for your newsletter, but check your metrics to find what works for your demographics. 

Shoot for negative churn (a growing subscriber base) and an open rate between 15% and 25%. (Note that available rates vary between industries, as well as the size and quality of your list.) Test different frequencies and see what works best for your audience.
