Tips for Marketing Emails

Due to the growing sophistication of email filters, it's important to follow best practices when designing email campaigns to prevent inadvertently landing in Junk mailboxes and to best engage with your customers to improve open rates.

We've compiled a list of do's and don'ts for creating effective marketing emails.


  • Proofread: Correct spelling and grammar errors to enhance professionalism. Mistakes can negatively impact your emails perception and even trigger spam filters.

  • Unsubscribe Options: Redbox provides recipients with an easy way to unsubscribe and tune the emails they receive to their preferences.

  • Suggest Adding to Address Book: Encourage users to save your email address to their contact list, reducing the likelihood of your emails ending up in the Junk folder.

  • Simplicity Matters: Keep emails concise, engaging, and easy to read. Recipients often have limited time, so a straightforward approach captures their attention effectively.

  • Monitor Performance: Keep track of the emails open rates. Analysing these metrics can help you refine your email strategies over time.

  • Include Relevant and Engaging Subject Lines: Craft subject lines that are clear, relevant, and capture the recipients interest without resorting to clickbait tactics.


  • Overload with Images: An excess of images can overwhelm recipients, making them unsure about the emails purpose and leading them to mark it as spam. Opt for a single, appropriately-sized image instead.

  • Capitals in Subject or Body: Capitalised words resemble shouting, an approach often used by spam emails. Steering clear of all caps maintains a professional and positive tone.

  • Trigger Words: Avoid using trigger words like "100% off," "Free," and "Full Discount," as they can activate spam filters and reduce the emails credibility.

  • Excessive Exclamation Points: Reserve exclamation points for crucial instances. Overusing them, especially in the subject line, can undermine the professionalism of the email.

  • Bury the Call to Action (CTA): Make your CTA clear and prominently placed within the email. Confusing or hidden CTA's can discourage engagement.

  • Neglect Segmentation: Sending the same email to your entire customer list can be ineffective. Segment your audience based on past ordering habits, activity and demographics for more personalised content.

  • Click Here: Move towards device independence and don't use CTA’s that contain click or tap.

Remember, the goal is to create meaningful connections with your audience through your marketing emails. Balancing engaging content with respectful practices will help you build strong customer relationships.
