Add Personalized Images to Email Campaigns with Daisy

ROS HODGEKISS - NOV 25, 2011

As of February 2013, Daisy will be turning off their API to all customers. Stay tuned – should the developers relaunch this service, we’ll be sure to let you know via this blog.

Looking for a sweet way to personalize your email campaigns? Our friends at Motobias have very cleverly applied themselves to the task with Daisy, a dynamic image generator that pulls personalization data from your subscriber list and uses it to generate unique images for each of your subscribers. The results are really eye-catching campaigns and great opportunities for designers to get creative with their own custom images.


While it’s still early days for Daisy, designers are welcome to generate images for their live email campaigns, for free. As any custom field can be used when personalizing an image using Daisy, its applications go beyond the gimmicky. For example, you can use it to generate personalized tickets to an event using ‘Name’ and ‘Ticket number’ custom fields in your subscriber list. In a similar manner, you can also create truly bespoke reminders and email invitations. Before we launch into the details, here’s an overview:

Powerful personalization for designers

If you’re a confident Photoshop user, then you’ll find that creating an image for use with Daisy is a snap. Simply create a PSD featuring an editable text layer and enter the name of your custom field (pictured).

You can convert this text layer into a smart object to apply effects like blur – Daisy will still be able to detect it as long as it remains editable.

With your masterpiece ready and at hand, it’s time to upload your PSD file to Daisy. Upon import, you will be issued an AppID (like an API key), which you will need to access your images. You’ll also get a chance to verify that your text layers have been detected.

At this point, it’s time to use your newly-minted AppID, plus Campaign Monitor API key and Client ID to create magic. Swing over to Daisy’s Campaign Monitor page and go through the prompts to create a new custom field in your Campaign Monitor account and a unique image for each subscriber in a list. The latter may take some time if you’ve got a large subscriber list, so Daisy helpfully sends you an email once this is complete.

Once your images are ready, you can go to your subscriber list and subscriber snapshot to see the new custom field you created earlier. For each subscriber, this custom field includes a URL which, as you’ve probably guessed, you’ll use to source your images. Take note that this new custom field will be visible in your preference center by default – you can hide it in ‘Manage custom fields’ in your subscriber list.

From here, it’s all fairly straightforward. In the email above, we simply added <img src="[chocolate-pic]"> to our HTML email code and sent a personalized email test. You can also set a fallback image URL, pointing to a non-personalized image – recommended, if you plan on sharing your campaigns.

Pretty as a Daisy?

To be honest, the Daisy interface may not be the prettiest in its ‘Experimental’ state, but it’s thorough, stable and full of possibility. Toying around with your own images brings a renewed wonderment towards email marketing – “How can I make my campaigns more exciting? Will my subscribers react to personalized campaigns?” – which I’m sure you’ll feel the moment you start sending wedding invitations for “*|firstname|* ♥ Justin Bieber” to your entire office. Either that, or you’ll be mobbed and killed quickly.

Not wanting to stop there, Motobias have also rolled out a well-documented API for dynamically generating images for both email and the web.

Down the track, Daisy will probably get rolled into their Visage service. But in the interim, try it for free and if you have any feedback, get in touch with the Daisy team. They’re keen to hear how they can make it even awesomer for designers… And Justin Bieber fans.
