Email personalization mistakes to avoid while using software

Email personalization using software is a powerful strategy for scaling marketing efforts. It improves open and click-through rates and fosters lasting and valuable customer relationships.

Recent data reveals that 72% of customers engage primarily with personalized marketing messages that cater to their specific interests. Additionally, 66% of customers expect businesses to understand their unique needs. These statistics underscore the vital role of personalization in email marketing, demonstrating its potential to elevate the success of your campaigns.

However, to personalize emails at scale, it's crucial to avoid common pitfalls. In this article, we'll explore these mistakes and offer solutions to help you overcome them effectively, ensuring your campaigns deliver the desired results.

7 Mistakes to Avoid When Using Software for Email Personalization

Here are 7 most common email personalization mistakes while using an email personalization software: 

1. Not Having a Well-Defined Personalization Strategy

One common mistake is marketers diving into personalization without a clear strategy. It's easy to feel overwhelmed with the choices, from personalization technologies to handling data effectively. Often, the focus shifts from meeting customers' needs to grappling with the mechanics of personalization.

To avoid this, consider a three-step approach:

  • Start Small: If you're new to personalization, don't rush into a full-fledged program. Begin with small, manageable steps. Identify areas where basic personalized data can enhance your messages, even something as straightforward as including personal data in emails.
  • Test Each Tactic: For each new tactic you introduce, assess its impact on your goals. Does adding personal data lead to higher click-through rates, conversions, or your chosen success metric? Testing allows you to measure the effectiveness of your efforts.
  • Optimize and Progress: Based on your test results, refine and optimize your tactics. Use the lessons learned to choose and implement additional personalization strategies, such as incorporating dynamic content modules into your campaigns.

By following this approach, you can navigate through the complexities of personalization without feeling overwhelmed and ultimately create more effective, customer-centric marketing campaigns.

2. Neglecting the Full Potential of Lifecycle Automation

Lifecycle automations, such as onboarding and first-purchase programs, win-back initiatives, and other customer-centric programs, are inherently tailored to individual preferences. These emails are characterized by highly personalized content and perfectly timed delivery, all driven by customer actions (such as opting in, making purchases, or downloading content) or inactions (like not opening emails, failing to make an initial purchase, or showing signs of disengagement post-purchase).

Even better, these emails launch automatically, eliminating the need for manual creation, scheduling, or sending. Your marketing automation platform takes care of all these tasks once you've set it up.

Failing to grasp your customer lifecycle fully and not optimizing automated messaging at these critical junctures is a missed opportunity. It can result in the loss of hard-earned customers and the potential revenue they bring to your business.

3. Over-segmenting Your Customer Base

While segmentation is a valuable tool for personalization, it's important not to take it to the extreme. Relying solely on highly segmented campaigns can lead to excluding and potentially losing customers who don't fit neatly into your segmentation criteria. This loss not only impacts your customer base but also the potential revenue and valuable data these customers could have provided to enhance your understanding of your audience.

To avoid this pitfall, consider implementing a data-driven segmentation strategy that you regularly review and test. Additionally, incorporate automated triggers to enhance the customer lifecycle and create a well-thought-out plan for default or catch-all campaigns to engage subscribers who may not align with your specific criteria. This balanced approach ensures that you maintain a healthy customer base while still reaping the benefits of segmentation.

To solve the mistake of over-segmenting your customer base, follow these steps:

  • Revisit and refine your segmentation criteria to align with marketing goals and avoid creating too many narrow segments.
  • Use data to guide segmentation efforts and identify meaningful patterns and segments.
  • Continuously review and test your segmentation strategy to adapt to changing customer preferences.
  • Use automated triggers to send targeted messages based on customer actions.
  • Develop a plan for campaigns targeting subscribers not fitting specific segments.
  • Gather customer feedback on content and communication preferences.
  • Continuously monitor campaign performance metrics to refine your segmentation strategy.

4. Neglecting a Personal Tone in Your Copy

You have the opportunity to infuse your email copy with a personal touch, even without specific data points. Imagine speaking to your customer in person and conveying that warmth through your writing. It's about adopting a human tone of voice, ideally aligned with your brand's voice. Your cold email copy should emulate a one-on-one conversation rather than coming across as a typical sales pitch.

This is precisely where the concept of "helpful marketing" comes into play. How does your brand assist your customers in achieving their goals, solving their challenges, or demonstrating that you recognize them as individuals, not just data entries?

5. Adapting a Short-term Perspective on Personalization

 Instead of merely asking, "How can I add personalization to this email campaign?" it's crucial to consider the broader, long-term approach: "How can I leverage personalization to enrich my customer's overall experience?"

Personalization shouldn't be limited to the initial email click. It should seamlessly extend to the landing page and even manifest in the content displayed on your website. The overarching goal is to enhance the customer's journey.

Think about what occurs when a customer engages with a personalized offer. Does your landing page welcome them by name? Does it showcase the items they expressed interest in? Does it provide tailored content that aligns with their preferences, loyalty program status, or any other unique data?

The essence here is to understand that personalization should be a continuous thread throughout the customer's experience, not just a one-time effort in an email campaign.

6. Failing to Include Dynamic Content in Generic Email Campaigns

When we talk about personalized emails, we usually think of messages tailored to customer behavior or preferences, whether it's evident, like an abandoned-cart email, or subtle, with content that's quietly relevant.

While advanced personalization involves real-time AI-driven messaging and intricate integrations with your e-commerce or CRM systems, a straightforward dynamic content module can yield similar results. 

By integrating this dynamic content into your general email, it can pleasantly surprise your customers and make your relevant content even more noticeable.

7. Neglecting Both Overt and Covert Email Personalization

Your focus on personalization up until now might have been primarily overt, involving visible tactics such as personalized subject lines, email copy tailored to specific actions, and triggered messages aligning with customer behavior and automation settings.

Covert personalization, on the other hand, employs customer data but does so discreetly without drawing attention to it. Instead of sending an abandoned browse message that explicitly states, "We noticed you were viewing this item on our website," you can subtly include a content module in your next campaign featuring those browsed items as recommended purchases, without highlighting their behavior. This approach is a smart way to avoid coming across as intrusive.


Personalizing emails plays an important role in cold email marketing, but it's equally important to steer clear of errors that could damage your reputation, offend, or reduce engagement.

By considering your audience's preferences and avoiding the common pitfalls mentioned earlier, you can create personalized emails that yield the intended outcomes. 

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
