Hi there, QR Codes are great and we like to include them in emails frequently. However it is quite time consuming having to download the QR Code from the QR Code page first and then upload it as an image, then scan the QR Code to find the URL it directs to so we can embed it in the image to make it clickable.
eg. We often embed a qr code for a Vcard as part of a signature so when people recieve an email on their laptop they can scan it with their phone and save the contact info to their device. However if they view email on their phone it needs to be clickable to do the same job. Or if they want to save the Vcard to their laptop contact manager being able to click it makes it a one step process.
