What is Image Personalization in Emails?

Before we get going, let's quickly recap image personalization in emails. As you might have guessed, it involves putting personalized images into every recipients' marketing emails – but instead of manually creating and adding each one, the images are dynamically created and inserted into emails automatically [1].

It's a powerful tactic that makes emails feel custom-made for each user.

Personalized images in emails work by tapping directly into CRM data [2]. From here, name, location, or even a specific product can be added directly within the dynamically generated image itself.

The most advanced personalized images are created from trigger behaviors in real-time [3]. For example, an image in a cart abandonment email can automatically show the exact product a customer left behind. It can also be based on items in a wishlist, recently browsed items, and then combined with sales and offers to majorly incentivize a purchase.

Frequent or recent purchases by users can also be featured, driving repeat sales.

Using names and birthday well-wishes are powerful tools, but image personalization in emails can do so much more. It can be used to target customers based on their interests and purchase intent, nudging them toward a sale.

All together, image personalization makes emails feel incredibly relevant and personal, significantly boosting engagement and conversion rates.

By how much, you ask? Let's get into that next…

How Image Personalization in Emails Drives Conversions

The impact of personalized images on the most important email marketing metrics is undeniable – the data don't lie. There is a clear link between image personalization and improved engagement, higher conversion rates, and more efficient campaigns [4]:

Increase in Conversions

Ultimately, the goal of any campaign is to increase revenue. Image personalization is proven to do this – just check out our post 9 Email Personalization Examples That Actually Convert to learn more.

It works because image personalization is super compelling for users; imagine seeing the very product you've been wanting for a while, land in your inbox, with a sale promotion, or just after payday… Timed properly, they're rocket fuel for conversions.

Targeted, relevant visuals like this help bridge the gap between interest and purchase – especially when paired with behavioral data and rules-based triggers.

By addressing customers directly with personalized offers and products they actually want, brands can achieve a direct, significant revenue impact. All they have to do is track and log how users browse – or just scrape users' wishlists to get all the data they need.

Companies that excel at personalization at scale generate 40% more revenue than companies that don't [5]. That might make it seem like it's rigged for bigger players, but personalization is great for any size of business. It's a far leaner way of working, and the extra efficiency just happens to scale well.

Personalized CTAs are another tool to use in the personalized image toolbox. They can produce a 202% higher conversion than generic CTAs [6], and become impossible to miss compared to text-based CTAs.

The bottom line is just one improvement that personalized emails offer. The fringe benefits that feed into future conversions and revenue are the real bonus.

Improved Engagement

Personalization makes emails more relevant, and relevance drives action. More engagement means more customers browsing, sharing, wishlisting – and eventually, buying.

Personalized emails mean future rewards for brands, through increased engagement. 91% of consumers say they are more likely to shop with brands who recognize, remember, and provide relevant offers and recommendations [7].

Engagement can be boosted even further by using the right type of visuals. Using a GIF in an email not only adds personality, but it has also been shown to increase email conversion rates. Dell's famously GIF-heavy campaign gained them a 103% increase in conversion rate, and a 109% increase in revenue [8].

Real-time Campaign Optimization

Image personalization tools also allow for real-time optimization at scale.

With dynamic images, a single campaign can be broken down into thousands of unique visual experiences. The technology makes it possible for the recipient's specific data to be pulled in to render a unique image on-the-fly – reducing resource use and maximizing efficiency (more on this later).

This level of customization used to be a major burden for development teams, but now tools like Sendtric's image personalization widgets handle all the heavy lifting. Our email image overlays automatically show the right text and image to the right person, which means you don't have to create multiple versions of your campaign just to change the text displayed. Instead, you design one email, and we handle the rest: swapping in the right text for each person who opens it.

For small teams, this gives you a level footing with the bigger fish in your pond.

For a large enterprise, this means a leaner marketing team can deliver the most engaging visuals to each segment of their audience, making the entire campaign more efficient and effective.

How Does Image Personalization Work?

Image personalization in emails is now far simpler than it used to be, thanks to a huge range of specialized tools – including our own!

Email image personalization is a technical process that replaces a static image in an email with a dynamic one, tailored to each recipient. The magic happens through a specialized image URL that contains "variables". These are placeholders for data, like a customer's name and location, or a product ID.

When a recipient opens the email, the email client sends a request to a server. The server reads the variables in the URL, pulls the corresponding data from your customer database in real-time, and uses the specified image assets to pair with it. It then combines them to generate a unique image instantly, just for that person.

This entire process happens in milliseconds – and the recipient sees their personalized image as the email opens, without any significant latency.

To make this work, you'll need your email service provider (ESP) and CRM to pull in customer data and generate dynamic visual content. And tools like Sendtric make adding image personalization into your emails as easy as any other customization.

If you're part of a larger enterprise, you'll need to lean on your CDP, a dynamic content platform, and a delivery system that can handle image rendering at scale. Sendtric is equally up to the task for large organizations as it is for small ones – with some of the biggest names in entertainment, retail, tech, and lifestyle trusting our platform to deliver personalized and dynamic content to their email lists.

In large enterprises, a CDP acts as a central repository for all customer information, including behavioral data like recent purchases, abandoned carts, and browsing history.

Sendtric can connect directly to your CDP, allowing you to create sophisticated rules-based images for email. Deep segmentation decides which visuals each customer receives. For instance – a rule might say, "If a customer viewed hiking boots in the last 24 hours, show them an image of those boots with a personalized discount banner", or something similar. You could also add in more information, like stock levels, to add a sense of urgency to your emails.

Modern ESPs are designed to work seamlessly with dynamic image URLs, and Sendtric works with all major platforms.

The ESP's job in all of this is replacing the variables in your image URL with the correct values from your customer profile, so that each recipient sees their own personalized version of the image. This means integrating with your CDP and/or CRM – and basically all ESPs make this as easy as possible, either through documentation or simple visual editors.
