10 things you shouldn't do within your newsletters

10 things you shouldn't do within your newsletters

Email newsletters are a powerful tool for keeping your audience informed, engaged, and connected to your brand. However, if you don’t approach your newsletters strategically, they can do more harm than good, leading to high unsubscribe rates, poor engagement, or even damaging your brand’s reputation. To make sure your newsletters are effective and well-received, here are 10 things you should absolutely avoid doing when communicating with your recipients.

 


1. Don’t overwhelm with too much content

One of the biggest mistakes is cramming your newsletter full of information. When you overload your email with too many articles, promotions, or images, it can feel overwhelming and lead to lower engagement rates. Subscribers want digestible content, not a lengthy report.

What to do instead:

  • Focus on a few key messages or highlights in each newsletter.
  • Use clear sections and keep the layout clean to make the content easy to scan.

2. Don’t Ignore Personalization

Generic newsletters that don’t speak directly to your reader can feel cold and impersonal. With so much competition for attention, newsletters that lack personalization are more likely to be ignored or even marked as spam.

What to do instead:

  • Use your recipient’s first name in the greeting, and segment your list to send tailored content based on interests, demographics, or previous engagement.
  • Personalize your subject lines and tailor content to fit the needs of different audience segments.

3. Don’t forget a clear call to action (CTA)

Your email newsletter should have a purpose, whether it’s driving traffic to your website, promoting a new product, or getting readers to engage with a blog post. A newsletter without a clear CTA is a missed opportunity.

What to do instead:

  • Include a strong, easy-to-understand CTA in every email.
  • Make sure your CTA stands out visually, whether through a bold button or hyperlinked text.

4. Don’t send emails without testing

Sending out a newsletter without testing how it looks or functions can lead to broken links, unreadable formatting, or images that don’t display properly. This creates a poor experience for your recipients.

What to do instead:

  • Always send test emails to yourself and your team before sending the newsletter to your audience.
  • Test across different email clients (e.g., Gmail, Outlook) and devices (desktop and mobile) to ensure it looks great everywhere.

5. Don’t use a misleading subject line

Clickbait or misleading subject lines may get you an initial open, but they can quickly erode trust with your audience. If the content of your newsletter doesn’t match the subject line, recipients will feel deceived and may unsubscribe.

What to do instead:

  • Make sure your subject line is relevant to the content of your email and delivers on its promise.
  • Aim for subject lines that are engaging, yet transparent about what’s inside.

6. Don’t neglect mobile optimization

More than half of all emails are opened on mobile devices, so if your newsletter isn’t mobile-friendly, you’re alienating a significant portion of your audience. Poor mobile formatting can lead to unreadable text, misaligned images, and a frustrating user experience.

What to do instead:

  • Use responsive email design that adapts to both desktop and mobile screens.
  • Keep your text concise, use larger buttons for CTAs, and make sure images scale properly on smaller screens.

7. Don’t send emails too frequently

Bombarding your subscribers with too many emails can lead to fatigue, frustration, and higher unsubscribe rates. Even if your content is valuable, sending too many emails can make your audience feel overwhelmed.

What to do instead:

  • Set a consistent email schedule that aligns with your audience’s preferences. Weekly or bi-weekly newsletters are common, but less frequent newsletters can also be effective.
  • Consider asking your subscribers how often they’d like to hear from you through preference settings.

8. Don’t skip the unsubscribe option

It’s tempting to keep your subscriber list as large as possible, but failing to include a clear unsubscribe option not only irritates your audience but also violates email marketing laws (like CAN-SPAM and GDPR). This could damage your reputation and lead to legal issues.

What to do instead:

  • Make sure your newsletter includes a visible and easy-to-find unsubscribe link at the bottom.
  • Respect those who choose to unsubscribe, and don’t make the process difficult.

9. Don’t send irrelevant content

Sending irrelevant content to your audience is a fast way to lose subscribers. If your newsletters consistently provide information that doesn’t align with your audience’s needs or interests, you’ll lose engagement and see higher unsubscribe rates.

What to do instead:

  • Segment your email list based on factors like purchase history, engagement levels, or demographic data, so you can send relevant, personalized content.
  • Use surveys or polls to find out what your subscribers are interested in and tailor your content accordingly.

10. Don’t forget to track performance

If you’re not tracking how your newsletters perform, you’re missing out on valuable insights that could help you improve. Ignoring open rates, click-through rates, and engagement metrics means you’re essentially operating in the dark.

What to do instead:

  • Use Mailchimp or other email marketing platforms to monitor key performance indicators like open rates, CTRs, bounce rates, and conversions.
  • Regularly analyze your email data and adjust your content, timing, and frequency based on what resonates most with your audience.

Conclusion

Avoiding these common newsletter mistakes will help you build stronger connections with your audience and increase engagement. By focusing on relevant, personalized content, optimizing for mobile, and making data-driven adjustments, you’ll ensure your newsletters are a valuable resource rather than just another email in your subscribers’ inboxes.

Remember, email marketing is about fostering relationships — and that starts with respect for your audience’s time and preferences. Keep your newsletters engaging, concise, and tailored to your subscribers’ needs, and you’ll see the benefits in higher open rates, more clicks, and better overall engagement.
