How Often Should You Send Marketing Emails?

Did you know that 69% of consumers unsubscribe from marketing emails because they receive too many emails from a brand? It's one of the biggest reasons people leave a mailing list, proving that finding the right email frequency is just as important as creating great content.

One of the questions businesses ask most is, "How often should I send marketing emails?" Unfortunately, there isn't a universal answer. Every audience is different, and what works for one business may not work for another.

The good news is that you don't need to rely on guesswork. By understanding your audience, monitoring performance and making gradual adjustments, you can find a sending schedule that keeps subscribers engaged without overwhelming their inbox.

In this guide, we'll explain how often you should send marketing emails, what influences the ideal frequency and how to create a strategy that keeps people opening, clicking and buying.

What Is Email Marketing Frequency?

Email marketing frequency is simply how often you send campaigns to your subscribers. Some businesses send one email a month, while others successfully send several each week.

Sending more emails doesn't automatically generate more sales. If subscribers receive too many messages that aren't relevant or valuable, they'll stop engaging or unsubscribe altogether. Equally, if you rarely email, your audience may forget who you are and become less likely to interact when you finally appear in their inbox.

Finding the right balance helps build familiarity and trust. Subscribers know what to expect, recognise your brand and are more likely to engage when your emails arrive.

It's also worth understanding the difference between frequency and cadence. Frequency refers to the number of emails you send, while cadence is the pattern in which you send them. For example, sending a newsletter every Tuesday morning creates a consistent cadence that your audience can become familiar with.

Is There an Ideal Email Frequency?

In short, no.

There isn't a perfect number of emails that every business should send. The right frequency depends on your audience, your products or services and the type of content you're delivering.

For example, an online fashion retailer running regular promotions will naturally email more often than an accountancy firm sharing business advice. Likewise, someone who has recently subscribed is likely to expect more communication than someone who joined your list several years ago.

Before deciding how often to email, ask yourself:

• How often do customers typically buy from you?
• Are your emails genuinely useful or just promotional?
• What expectations did you set when people subscribed?
• How engaged is your audience currently?

Instead of asking, "How many emails should we send?", it's often better to ask, "How many valuable emails can we send?"

How Often Should You Send Marketing Emails?

For many businesses, one to three marketing emails per week is a sensible starting point. From there, you can review your results and adjust your frequency based on how subscribers respond.

The type of email you're sending also matters.

A weekly newsletter keeps your business visible while giving you time to create useful content. Promotional campaigns may be sent more frequently around product launches or seasonal sales, as customers are expecting those communications.

Transactional emails, such as order confirmations or delivery updates, should always be sent immediately because they're triggered by customer actions.

Automated email journeys work slightly differently. A welcome series is often most effective when delivered over the first few days after someone subscribes, as this is usually when engagement is highest. Likewise, abandoned basket emails should be sent soon after a customer leaves your website, with a carefully timed follow-up if they haven't completed their purchase.

Different Industries Have Different Expectations

Not every business should follow the same approach.

An ecommerce brand selling fashion, beauty or homeware may comfortably send several emails each week because customers expect regular offers, new arrivals and seasonal promotions.

B2B businesses often benefit from a slower pace. Weekly or fortnightly emails filled with expert advice, industry insights or customer success stories usually provide more value than frequent sales-focused campaigns.

Hospitality businesses may increase their frequency around holidays or major events, while charities often communicate more during fundraising campaigns before returning to a lighter schedule.

The key is understanding what your audience expects. If subscribers joined knowing they'd receive a weekly newsletter, maintaining that consistency helps build trust.

Finding the Right Frequency

Choosing the right email frequency isn't about luck. It's about testing, measuring and refining your strategy over time.

Start with a sensible schedule, then monitor how your audience responds. While open rates are useful, they shouldn't be your only focus. Pay attention to click-through rates, conversions, sales and unsubscribe rates to build a clearer picture of performance.

Segmentation can also make a significant difference. Highly engaged subscribers may welcome more regular communication, while less active contacts might respond better to fewer emails or a dedicated re-engagement campaign.

Whatever changes you make, avoid dramatically increasing your email volume overnight. Small, gradual adjustments make it much easier to understand what's improving your results.

Best Practices for Email Marketing

Successful email marketing isn't just about how often you send emails. It's about giving subscribers a reason to keep opening them.

Start by understanding why people joined your mailing list. If they signed up for expert advice, don't overwhelm them with constant sales messages. If they're expecting offers and discounts, make sure you're delivering them consistently.

Consistency is equally important. Whether you send emails weekly or fortnightly, sticking to a regular schedule helps build familiarity with your brand.

Personalisation can also improve engagement. Modern email marketing platforms allow you to tailor campaigns based on previous purchases, browsing behaviour or subscriber interests, making your emails feel far more relevant.

Finally, aim for a healthy balance between promotional content and genuinely useful information. Educational articles, product tips, customer stories and helpful advice often perform just as well as discount-led campaigns because they continue providing value between purchases.

How to Avoid Email Fatigue

Email fatigue happens when subscribers become overwhelmed by the number of emails they receive or feel the content is no longer relevant. While sending too many emails can contribute to this, frequency isn't always the main issue. Often, people unsubscribe because the emails they're receiving don't match their interests or expectations.

There are several warning signs that your audience may be experiencing email fatigue. Falling open rates, declining click-through rates, rising unsubscribe numbers and an increase in spam complaints can all indicate that it's time to review your strategy.

One of the simplest ways to prevent email fatigue is to make every campaign worthwhile. Before hitting send, ask yourself whether your email provides genuine value. That could be expert advice, product recommendations, exclusive offers or useful updates your audience actually wants to receive.

Giving subscribers more control can also improve long-term engagement. An email preference centre allows people to choose how often they'd like to hear from you or the type of content they want to receive. Rather than losing subscribers completely, you can simply reduce the number of emails they receive while keeping them connected to your brand.

Should You Send More or Fewer Emails?

Many businesses worry about sending too many emails, but sending too few can be just as damaging.

If customers rarely hear from you, they may simply forget your business. When your next campaign finally lands in their inbox, they might not remember subscribing and decide to unsubscribe instead.

Equally, increasing your email frequency without improving the quality of your content is unlikely to deliver better results.

Instead of focusing on the number of emails you send, let your data guide your decisions. If engagement remains strong, unsubscribe rates stay low and campaigns continue generating sales, there may be room to increase your frequency. If the opposite is happening, it could be time to reduce your sends or rethink your content.

The goal isn't to send as many emails as possible. It's to send the right emails at the right time.

Measuring Whether Your Email Frequency Is Working

Finding the right email frequency means looking beyond open rates alone.

While open rates provide a useful indication of subject line performance, they don't tell the whole story. A campaign with fewer opens may still generate more revenue if it encourages more people to click and convert.

When reviewing your email performance, consider several metrics together, including:

• Click-through rate
• Conversion rate
• Revenue generated
• Unsubscribe rate
• Spam complaints
• Deliverability

Looking at the bigger picture helps you understand how your audience is responding and allows you to make informed decisions based on real customer behaviour rather than assumptions.

How to Test Your Email Frequency

Testing is the most effective way to find the right sending schedule.

Start by dividing your audience into two similar groups. Send one group a single email each week and the other group two or three emails over the same period. Keep everything else as consistent as possible so that frequency is the only variable.

Allow the test to run for several weeks before reviewing the results. Compare engagement, conversions, revenue and unsubscribe rates rather than relying on a single metric.

If the group receiving more emails generates higher revenue without increasing unsubscribes, you may be able to increase your overall sending frequency. If engagement drops or unsubscribe rates rise, you'll know your audience prefers fewer emails.

Small, controlled tests provide far more reliable insights than making large changes all at once.

Keep Your Subscriber List Healthy

A healthy email list is just as important as finding the right frequency.

Over time, every mailing list collects inactive contacts. Some people change email addresses, others lose interest and some simply stop engaging. Continuing to email these subscribers can reduce overall engagement and negatively affect your sender reputation.

Review your list regularly and identify contacts who haven't opened or clicked an email for several months. Before removing them, consider sending a short re-engagement campaign asking if they'd still like to hear from you.

If they remain inactive, removing them is often the best option. Although your subscriber count may decrease, your engagement rates and deliverability are likely to improve.

Common Email Marketing Mistakes

One of the biggest mistakes businesses make is treating every subscriber the same. Customers have different interests, buying habits and levels of engagement, so sending identical emails to everyone rarely produces the best results.

Another common mistake is only emailing when there's something to sell. If every campaign is promotional, subscribers can quickly lose interest. Mixing offers with educational content, customer stories, helpful guides and product advice creates a much more balanced experience.

Many businesses also ignore their own performance data. Your audience tells you what they want through their actions. If engagement is increasing, your strategy is probably working. If unsubscribe rates begin to climb, it's time to review your content or sending frequency.

Finally, avoid making dramatic changes overnight. Gradual improvements are much easier to measure and are less likely to overwhelm your subscribers.

Conclusion

There's no single rule for how often you should send marketing emails. The right frequency depends on your audience, your industry and the value your emails provide.

For most businesses, sending one to three emails each week is a sensible starting point. From there, monitor your performance, test different approaches and make gradual improvements based on how your subscribers engage.

Successful email marketing isn't about filling inboxes. It's about delivering the right message at the right time, consistently providing value and building stronger relationships with your audience.
