How Often Should Your Business Send a Newsletter?

9 min read

Are you sending newsletters often enough?

Many businesses send a newsletter when they have a special offer, a new product or something urgent to announce. Then weeks or months pass before the next email goes out.

The problem? Customers can forget who you are, miss useful updates and become less familiar with your business.

At the other extreme, sending too many emails can overwhelm subscribers and lead to unsubscribes.

The goal is not to send more emails. It is to communicate consistently, with a clear reason for every send.

For South African small and medium-sized businesses, a manageable newsletter schedule can help maintain customer relationships, encourage repeat business and grow an engaged audience without requiring a large marketing budget.

Here is how to choose a frequency that works for your business.

How often should you send a newsletter?

There is no single schedule that suits every business. Your ideal frequency depends on what you sell, how often you have something useful to share and what your subscribers expect.

As a starting point, consider these options:

Weekly newsletters

A weekly newsletter may suit businesses that regularly have useful updates, industry insights, product information or practical advice to share.

For example, a business supplying office equipment could send a short weekly update featuring product guidance, maintenance advice or relevant stock announcements.

The important point is to provide enough value to justify the frequency. If you struggle to find something useful to say every week, a less frequent schedule may be more appropriate.

Fortnightly newsletters

A newsletter every two weeks can provide a manageable balance for businesses that want to stay in regular contact without creating content every week.

A South African professional services firm, for instance, could alternate between practical advice, frequently asked questions and updates about its services.

This schedule gives the business time to prepare useful content while maintaining regular contact with subscribers.

Monthly newsletters

A monthly newsletter can work well for smaller businesses with limited time or a more occasional need to communicate.

A monthly edition might include company news, a helpful tip, a product or service update and a clear next step for interested customers.

However, monthly sending should not become an excuse to disappear between campaigns. Make sure the newsletter delivers genuine value and that the interval matches what subscribers were told to expect.

These are starting points, not industry benchmarks. The best schedule is one your business can maintain and your subscribers find useful.

Five questions to help you choose the right frequency

Before committing to a schedule, consider the following.

1. How often do you have something useful to share?

Your newsletter should give readers a reason to open it and engage with your business.

Useful content might include:

  • Advice that helps customers solve a problem.
  • New products or services relevant to their needs.
  • Practical answers to frequently asked questions.
  • Important business or service updates.
  • Offers that genuinely benefit your audience.

If you have useful information every week, weekly communication may be appropriate. If your content is more occasional, fortnightly or monthly sending could be a better fit.

Avoid sending a newsletter simply because it has been a certain number of days since your previous campaign.

2. What have your subscribers agreed to receive?

Set expectations when people sign up.

If your form promises a monthly newsletter, do not unexpectedly start sending several marketing emails each week. If you offer different types of updates, make the options clear and respect the preferences people select.

For South African businesses, this also means following POPIA requirements and BulkMail's permission policy. A contact's email address is not, by itself, permission to send ongoing marketing communications.

Every marketing newsletter should include a clearly accessible unsubscribe link.

3. How much time can your business realistically commit?

A newsletter programme should be sustainable.

If preparing a weekly newsletter takes time away from serving customers, a simpler fortnightly or monthly format may be more practical.

Create a basic content plan in advance. You could prepare several newsletter ideas from common customer questions, product information or articles already published on your website.

For example, a blog post explaining how to prepare for a seasonal busy period could become a short newsletter linking readers to the full article.

This helps you maintain a regular schedule without constantly starting from scratch.

4. How relevant is your content to different customers?

Not every subscriber needs every message.

A business selling to both trade customers and individual business owners may have different products, pricing arrangements or information to share with each group.

Rather than increasing email frequency by sending everything to everyone, consider whether separate, relevant newsletters would be more useful.

Segmentation can help you communicate according to customer interests, provided your contact records, permissions and preferences support that use.

5. What do your campaign results tell you?

Your own campaign history is more useful than blindly copying another business's schedule.

Review delivery failures, unsubscribes, complaints where available, clicks and meaningful outcomes such as enquiries or purchases.

Recorded opens can provide some context, but privacy features mean an open does not always indicate that a person actually read the message.

Look for patterns across comparable campaigns. If unsubscribes increase after you change your sending frequency, investigate whether the new schedule or the content itself is contributing to the change.

Do not assume frequency is the cause without considering other factors.

How to tell whether you are sending too often

Sending more frequently is not necessarily a problem. Sending more frequently without providing sufficient value is.

Watch for these warning signs:

  • Unsubscribes increase after a change in sending frequency.
  • Spam complaints rise or recipients report unexpected messages.
  • You are repeatedly sending similar content without a clear purpose.
  • Your team struggles to maintain quality and accuracy.
  • Customers receive messages that are irrelevant to their interests.

If you notice these patterns, review the content, the audience and the schedule.

Consider whether subscribers were told what to expect, whether the newsletter remains useful and whether different customer groups should receive different messages.

Do not simply reduce your frequency automatically. Sometimes the real issue is that the content is no longer relevant or does not match the original sign-up promise.

What happens when you send newsletters too infrequently?

Infrequent sending can create a different set of problems.

If customers hear from you only when you want to sell something, your communications may feel transactional rather than helpful. Subscribers may also struggle to remember why they signed up in the first place.

Long gaps can make it harder to establish a recognisable, consistent relationship with your audience.

You do not need to send weekly to avoid this. Instead, choose a realistic schedule and communicate useful information between major promotions.

For example, a local accounting firm could share occasional tax-planning reminders, explain common bookkeeping mistakes or provide a link to a practical guide relevant to its clients.

The aim is to remain useful and recognisable—not to fill inboxes unnecessarily.

Build a simple newsletter schedule

You do not need an elaborate marketing calendar to get started.

Use a basic plan that identifies when you intend to send, what the newsletter will cover and why the content matters to your audience.

For example:

NewsletterPossible contentPurpose
First editionA useful industry tip or practical guideProvide value and build trust
Second editionProduct or service informationHelp customers make informed decisions
Third editionAnswers to common customer questionsAddress barriers and encourage enquiries
Fourth editionRelevant updates or a seasonal reminderMaintain contact and prompt an appropriate next step

This is a sample content framework, not a recommendation to send four newsletters every month. Adapt it to your chosen frequency and the value you can realistically provide.

You can also reuse suitable website content. Turn a detailed article into a concise newsletter introduction, then link readers to the full guide. This helps your website content reach more subscribers without duplicating the entire article in the email.

For South African audiences, keep emails practical on mobile devices. Use readable text, lightweight images and clear links that are easy to tap.

How to test whether your newsletter frequency is working

Once you have selected a schedule, maintain it long enough to gather useful comparisons, provided delivery and complaint signals remain healthy.

Then review the results.

Step 1: Establish a baseline

Record how your recent campaigns perform. Include list growth, delivery failures, unsubscribes, complaints where available, clicks and relevant business outcomes.

Step 2: Change one thing at a time

If you want to test a different frequency, avoid simultaneously making major changes to your content, audience and offer. Otherwise, it becomes difficult to understand what influenced the results.

Step 3: Compare similar campaigns

Compare campaigns with similar audiences and objectives. A seasonal promotion may behave differently from an educational newsletter, so avoid drawing conclusions from unrelated sends.

Step 4: Make a practical decision

If a new schedule improves useful engagement without creating warning signs, continue evaluating it. If results deteriorate, investigate the likely causes and consider returning to the previous schedule.

The objective is not to find a magic number of emails per month. It is to establish a reliable communication routine that supports your business and respects your subscribers.

Do not forget to grow your email list

A consistent newsletter schedule works best when your business continues attracting relevant new subscribers.

If your list is not growing, even a well-written newsletter will have a limited audience over time as people unsubscribe, change jobs or stop using old email addresses.

Here are three practical ways to support list growth:

Make newsletter sign-up easy to find

Add a clear newsletter invitation to relevant pages on your website. Explain what subscribers will receive and, where appropriate, how often they can expect to hear from you.

Turn useful articles into subscriber opportunities

Your website blog can help attract people searching for answers to problems your business solves. Include a relevant invitation to subscribe where it makes sense, with clear information about the emails they will receive.

Give subscribers a reason to stay

Focus on practical advice, relevant updates and content that helps customers make better decisions. A useful newsletter gives subscribers a reason to remain on your list and look forward to future communications.

Use permission-based sign-up methods, retain appropriate consent records and respect opt-outs. Do not purchase or import unrelated contacts simply to increase your list size.

BulkMail's forms and landing pages can support your efforts to capture new subscribers and organise your email marketing activity.

Keep your newsletters consistent, useful and permission-based

The right newsletter frequency is the one that balances your business capacity with your subscribers' expectations.

Start with a manageable schedule, communicate what subscribers can expect and deliver useful content consistently. Monitor your campaign results, investigate warning signs and make adjustments based on evidence rather than assumptions.

Most importantly, keep growing your permission-based list. A newsletter programme should help your business build lasting customer relationships—not simply send more emails.
