Email marketing remains one of the most powerful tools for engaging and converting customers in the digital world.
However, one of the biggest questions among marketing professionals is: what is the ideal frequency to send emails ?
It’s a delicate balance. Sending too many emails can irritate your contacts and lead to mass unsubscribes, while not sending enough emails can lead to forgetfulness and missed conversion opportunities.
Why is frequency important?
Email frequency directly affects two crucial indicators in digital marketing: the open rate and the unsubscribe rate .
If emails are sent too frequently, contacts may feel like they are being bombarded, which can lead to a lower open rate and more unsubscribes.
On the other hand, low frequency can cause customers to forget about the brand, leading to lower retention and engagement.
According to data from Campaign Monitor , companies that have found the right balance have, on average, a 20-30% open rate and a 3-5% click-through rate .
Those who send emails too much or too rarely see their open rates drop below 15%, with a proportional increase in the unsubscribe rate.
Types of emails and recommended frequency
To understand the best frequency, it is essential to first classify the types of emails you can send:
Transactional emails : These are sent after a specific customer action, such as a purchase, registration or download of a material. Their open rate is generally higher, as contacts expect these emails. They have an average open rate of 40-50% and are not influenced by overall frequency. As they are triggered by specific actions.
Promotional emails : These are used to promote sales, events, and seasonal offers. According to a study by MailChimp , promotional emails sent once a week have the best conversion rate. With an open rate of 18.8% and a click-through rate of 2.5% . The recommended frequency for newsletters ranges from weekly to biweekly. Depending on the industry. B2B companies tend to send newsletters biweekly, while B2C companies may benefit from a weekly frequency.
These emails have a high conversion rate, reaching as high as 4-8% .
Seasonal emails : Sent during periods of important events for the target audience. Such as holidays and special occasions. The frequency of these emails must be carefully planned so as not to overwhelm the customer during critical periods such as Black Friday, where competition is intense.
What do market statistics say about email frequency?
A HubSpot survey showed that 35% of marketers believe that a frequency of 1 to 2 emails per week is ideal to maintain engagement without annoying subscribers.
MarketingSherpa reveals that 61% of consumers prefer to receive phone number library promotional emails at least once a week, and 15% prefer to receive emails daily .
However, audience behavior varies by industry.
Below are some average numbers by industry, based on a GetResponse study :
E-commerce : Sending 3 to 4 emails per week is considered ideal, especially for short-term promotions.
B2B : Frequency of 1 to 2 emails per week , focusing on educational content and newsletters.
Financial Services : 2-3 emails per week can be effective, but with an emphasis on value-added content such as financial tips and reports.
SaaS : Frequency of 1 email per week , focusing on product updates and post-purchase engagement.
Factors that influence the frequency of sending emails
The ideal frequency depends not only on general data, but also on a series of factors that vary depending on the audience and the type of company. Here are the main ones:
For example, customers who are in the final stage of the sales funnel how to increase brand awareness of your company may receive more frequent promotional emails, while cold leads may benefit from monthly newsletters.
Customer Lifecycle Consider where your customer is in the lifecycle. For example, new subscribers may benefit from a more intensive welcome sequence with daily emails for the first week. Loyal customers may prefer to receive only relevant emails, such as product updates or exclusive offers, once a week or less.
Defined Expectations From the moment they sign up, it’s important to set your subscriber’s expectations. Let them know how many emails they’ll receive and how often. This can help reduce the unsubscribe rate, as the customer knows what to expect.
Engagement Analytics Use engagement data to adjust your frequency. If you notice that your open and click rates are decreasing while your unsubscribe rate is increasing, this could be an indication that your frequency is too high.
Impact of frequency on engagement
Research from Litmus showed that 78% of consumers unsubscribe from an email list because they are receiving too many emails.
On the other hand, 44% say that receiving too few messages causes twd directory them to lose interest in a brand . This balance is vital to avoid damaging the relationship with subscribers.
Companies that send emails very frequently (more than once a day) see a 40% increase in unsubscribe rates , according to data from Mailchimp.
A/B testing to find the ideal frequency
A key practice for determining the best frequency is A/B testing . This allows you to test different sending cadences to control groups and see the impact on engagement.
Here’s how to conduct an effective test:
Define control groups : Separate your subscriber base into two or more groups.
Vary the frequency : Send emails daily to one group, three times a week to another, and weekly to a third group.
Monitor metrics : Track open, click, conversion, and unsubscribe rates.
Analyze the results : After a testing period (usually 1-2 months), compare the results. Groups that show a sharp drop in open rate or an increase in unsubscribes indicate a very high frequency.
Best practices for determining frequency
Beware of seasonal events : During major promotions like Black Friday, it’s common to increase the frequency of emails. However, be sure to let your subscribers know in advance about the temporary increase in messages to avoid a spike in unsubscribe rates.
Give your subscribers control : Give your contacts the option to choose the frequency of their emails.
Personalization and relevance : Relevance of content can allow for higher frequency without annoying subscribers. The more personalized the email, the less intrusive it will feel, even if sent more frequently.
Monitor list health : Keep an eye on engagement metrics and periodically “clean” your list by removing inactive contacts or offering them an option to re-engage with a reduced frequency of emails.

However, the key to an effective email marketing strategy is finding the right balance between keeping your subscribers engaged without overwhelming them.
Rely on A/B testing, data analysis, and segmentation to adjust your frequency over time.
