Getting the right email send frequency is one of the most consequential decisions you make as an email marketer. Send too often and subscribers tune out, mark you as spam, or unsubscribe. Send too rarely and they forget you exist. Neither outcome is good for deliverability, revenue, or long-term list health.
The data makes this tension clear. According to GetApp's 2024 Advertising Preferences Survey, 50% of readers unsubscribe because they receive too many emails. At the same time, under-emailing reduces customer interest, because subscribers expect emails at a regular interval, and if your frequency gets too low, they may not recognize your brand or might forget why they subscribed in the first place.
This guide covers the best practices for email marketing frequency, grounded in current data, so you can find a cadence that protects your sender reputation and drives real ROI.
Key Takeaways
After analyzing more than 15 billion emails sent in 2024, weekly sending is the most common cadence, used by 65.62% of senders.
69% of users said that getting too many emails from a brand makes them opt out.
Marketers sending 1 to 2 newsletters per week see open rates of 48.31% and click-through rates of 5.7%, with 2 newsletters per week considered the sweet spot for maintaining high engagement.
Automated emails drove 18% of orders in 2024 while making up only 9% of sends, with automation sequences generating higher returns than broadcast campaigns.
Segmentation and subscriber preference controls reduce unsubscribe rates and let you increase relevant sends without harming list health.
Why Email Frequency Has a Direct Impact on ROI
Email marketing generates between $36 and $40 for every dollar spent, translating to a 3,600% to 4,000% return on investment. But that return depends heavily on frequency decisions. Getting it wrong in either direction erodes results.
Your sending schedule directly impacts open rates, clicks, and revenue. Send too often and subscribers tune out or unsubscribe. Send too rarely and they forget your brand exists.
Send frequency is not a standalone metric to optimize. It is a force multiplier. When aligned with relevance, segmentation, and lifecycle messaging, it strengthens revenue and subscriber loyalty. When misaligned, it accelerates fatigue and erodes trust.

The Benchmark: How Often Do Most Businesses Send?
There is no universal correct answer, but the data provides useful guardrails.
Large-scale analyses of email programs show that weekly sending remains the dominant rhythm. Approximately 65% of senders use a weekly cadence, while about 16% send daily newsletters. The remaining segment is spread across biweekly, monthly, and less frequent schedules.
Industry-specific patterns vary meaningfully:
39.27% of entrepreneurs and SMBs send between 1 and 3 emails per month, the most common cadence for that group, with 29.12% sending once a week.
39.73% of online course creators send 2 emails per week or more, while 39.21% of software and web app businesses send between 1 and 3 emails per month.
Landing between two to four monthly messages suits most ecommerce businesses, while one to three weekly emails maintains optimal engagement without causing list burnout.
Use these figures as a starting point, not a ceiling. Your audience's behavior and your content quality should be what ultimately determines your cadence.
6 Best Practices for Email Marketing Frequency
1. Start with a Consistent Baseline and Build from There
Consistency matters more than volume when you are starting out. Engage consistently but avoid overwhelming: aim to send at least one email per month to maintain familiarity. Starting with a predictable weekly or biweekly send establishes a relationship before you experiment with higher frequency.
Once you have baseline data, you can run structured tests to find what your specific audience tolerates and responds to.
2. Use A/B Testing to Find Your Audience's Threshold
The wrong way to deal with email marketing frequency is to blindly follow other companies. Your audience, your product, and your goals are unique, which is why you should keep holding A/B tests to constantly improve. Try dividing your subscribers into groups based on their activity and test an updated email frequency on a subset from each group. The frequency option that brings the most engagement should be adopted.
A practical testing approach:
Divide your list into two or three groups.
Assign each group a different send frequency for four weeks.
Measure open rate, click rate, unsubscribe rate, and revenue per recipient.
Adopt the frequency with the best combined outcome.
Brands that regularly A/B test their emails achieve 83% higher ROI than those that never test. Companies that never test report average ROI of 2,300%, while those that often test achieve 4,200%.
3. Monitor Engagement Metrics Continuously
One of the most important email marketing frequency best practices is to avoid fatigue: when subscribers are tired of seeing your emails, they show signs of low engagement. Low engagement can eventually lead to unsubscribes, spam complaints, block lists, and an adverse effect on your sender reputation.
Watch for these early signals before they become a deliverability problem:

One of the most important email marketing frequency best practices is to avoid fatigue: when subscribers are tired of seeing your emails, they show signs of low engagement. Low engagement can eventually lead to unsubscribes, spam complaints, block lists, and an adverse effect on your sender reputation.
Watch for these early signals before they become a deliverability problem:
Watch for dropping open rates, especially from previously active subscribers. Click rates often fall faster than opens, indicating diminishing interest in your content.
A rising unsubscribe rate above 0.5% warrants immediate attention. A good unsubscribe rate generally falls below 0.5%, with rates above 1% signaling potential issues with targeting, content relevance, or sending frequency.
A sudden spike in unsubscribes often signals irrelevant content, poor targeting, and excessive frequency.
Check your email marketing analytics on a per-campaign basis, not just monthly. Trends show up early at the campaign level before they appear in aggregate reports.
4. Segment Your List and Apply Frequency by Engagement Level
Not everyone in your audience wants to hear from you with the same frequency. Use segmentation to adjust your email frequency based on user behavior and interaction level. Active users might receive more frequent communications than less engaged subscribers.
Segmentation is one of the most effective levers for managing frequency without sacrificing results. Segmentation ensures your emails stay relevant, which is why 90% of email marketers report better email performance from segmentation.
A practical engagement-based segmentation framework:
Highly engaged (opened in the last 30 days): Can receive higher frequency, including promotional sends.
Moderately engaged (opened in 30 to 90 days): Stick to a standard weekly or biweekly cadence.
At-risk (no opens in 90 days): Reduce frequency and trigger a re-engagement sequence before suppressing.
5. Give Subscribers Control with a Preference Center
Not every person who unsubscribes actually wants to unsubscribe. Some of them simply want fewer emails. Without a subscriber preference center, subscribers are presented with the painful dilemma of choosing between getting all of your emails or none of your emails. If it is the only way to reduce the number of emails they get, many people will choose not to receive any.
A preference center lets subscribers self-select their cadence. Offering three clear frequency options works well in practice: send me everything, send to me once per week, and send to me once per month. This gives subscribers enough control without overwhelming them with choices or significantly impacting your bottom line.

Offering three clear frequency options works well in practice: send me everything, send to me once per week, and send to me once per month. This gives subscribers enough control without overwhelming them with choices or significantly impacting your bottom line.
Giving customers more control over how they receive communications makes every email more welcome and improves click-through rates. It also helps lower your unsubscribe rate.
Notably, 60% of marketers do not give subscribers the option to select the types of emails they want to receive, and only 30% allow subscribers to decide how often they want to be emailed. This is a straightforward advantage most brands leave on the table.
6. Increase Frequency Strategically Around Key Moments
It is normal for brands to increase email frequency around key moments. Subscribers expect these emails and look forward to them. Seasonal campaigns, product launches, and promotional events are natural exceptions to your standard cadence.
According to Optimove's 2025 Marketing Fatigue Report, 56% of consumers say Black Friday and Cyber Monday campaigns increase their likelihood to purchase, as long as offers are personalized to their interests.
The principle: temporary frequency increases are tolerated when the content is visibly relevant and time-bound. They become damaging when they carry no clear reason for the subscriber to care.
The Role of Automation in Frequency Strategy
Automated emails deserve their own mention because they operate on a different logic. Rather than broadcasting to your full list on a calendar schedule, they trigger based on subscriber behavior, which makes them inherently more relevant.
Open rates rose for the fifth consecutive year, reaching 30.7% in 2025, while automated emails reached a 38% open rate and generated $2.87 per email compared to $0.18 for broadcast campaigns. Automations accounted for just 2% of email sends but drove 30% of revenue, earning 16 times more per send than scheduled campaigns.
In 2024, automated emails outperformed scheduled ones by 52% in opens, 332% in clicks, and 2,361% in conversions.
This means a well-structured automation layer, covering welcome sequences, abandoned carts, and re-engagement flows, can increase your effective sending volume without the fatigue risk of manual broadcast campaigns. A good welcome email sequence sets the right expectations for frequency from the first message.

Treat these as defaults. Your analytics, not industry averages, should drive your final cadence. Review your email marketing analytics regularly and let engagement patterns guide adjustments.
What Under-Emailing Costs You
Most frequency conversations focus on the risk of over-sending. Under-emailing has real costs too, and they are less visible.
Under-emailing can reduce customer interest because subscribers expect emails at a regular interval. If you fail to provide relevant content regularly, subscribers might lose interest in your brand. If your email frequency gets too low, subscribers may not recognize your company or might forget why they subscribed in the first place.
A dormant list also degrades in quality. Email addresses change, spam traps accumulate, and engagement signals weaken. Clean email lists deliver higher engagement, better deliverability, and more accurate testing results. Regular contact is part of what keeps a list healthy.
The practical floor: at a minimum, email your list once a month to maintain brand recognition and list hygiene. If you are sending less than that, you are likely missing revenue and eroding the quality of your list simultaneously.
Frequently Asked Questions
How often should I send marketing emails?
Research shows that most companies send two to five emails weekly to engaged subscribers, but the optimal frequency depends on the audience's unique preferences, behavior, and message types. A good starting point for most businesses is one to two emails per week, with adjustments based on your open rates, click rates, and unsubscribe data over time.
What is a good unsubscribe rate for email marketing?
Across multiple industry studies, average unsubscribe rates typically range from 0.1% to 0.3% per campaign in stable programs. A shift from 0.15% to 0.22% can look dramatic in reporting dashboards while remaining within normal operational boundaries. Rates consistently above 0.5% are worth investigating for root causes like excessive frequency, poor segmentation, or irrelevant content.
Does sending more emails increase revenue?
Not automatically. Brands sending 9 to 16 emails monthly achieve average ROI of 4,600%, the highest of any frequency bracket, but this sweet spot balances subscriber engagement with list fatigue. Beyond a certain threshold, more sends produce diminishing returns and accelerate list churn. The quality and relevance of each email matters as much as the volume.
How does segmentation affect email send frequency?
Segmentation lets you send more frequently to highly engaged subscribers while reducing pressure on less active ones, protecting your overall list health. According to segmentation data from Klaviyo, sending highly segmented emails (campaigns sent to less than 20% of your complete subscriber list) can reduce your unsubscribe rate by 50% compared to unsegmented lists. Effective email personalization techniques compound these gains further by making each email feel relevant to the individual receiving it.
