Marketo Removing Code for Image Scaling for Outlook at 125%dpi

Anonymous · ‎06-19-2015

We’re having an issue with email rendering on Outlook 2013 (125% dpi) wherein the images stray from the set boundaries of the parent table. Upon further inspection, we’ve noticed that Marketo appears to be removing the header markup necessary for correct image scaling in Outlook at 125%dpi. I’ve attached screenshots of the code from before and after sending through Marketo.

Is there a way to stop Marketo from removing that code, or another workaround to adding it?

Pre Marketo code -

<!DOCTYPE html> 
<html xmlns="http://www.w3.org/1999/xhtml" 
xmlns:v="urn:schemas-microsoft-com:vml" 
xmlns:o="urn:schemas-microsoft-com:office:office"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> 
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

Post-Marketo code -

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> 
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

Any help would be much appreciated.

We will be releasing this feature with a patch outside of our normal release schedule and I want to explain how it will work. The items will be applied to our production code tonight (10/13) and will be available for activation starting tomorrow. It will not be turned on automatically for all customers. We will, however, enable the feature on an ad-hoc basis for those that are interested. If you would like this feature enabled, please email me atjcooperman@marketo.com and tell me the Munchkin ID of your subscription.

While this functionality has been thoroughly tested, we won't be enabling this for all customers for 1-2 months. It is a large change and it is important that you understand (and communicate to your team) the behavior before choosing to enable this.

With this feature enabled, you will see the following behavior:

Custom DOCTYPES will not be stripped from your Email Templates when creating new Emails in Marketo.
Custom HTML attributes will not be stripped from your Email Templates when creating new Emails in Marketo.

Please Note:

Your custom DOCTYPE will persist only if it is the very first line of your Email Template or what you are pasting into Email Actions > HTML Tools > Replace HTML. If the DOCTYPE is anywhere else, it will be stripped and replaced with Marketo's default DOCTYPE.
If you have existing Email Templates that already have custom DOCTYPES, they will now persist into your new Emails once the feature is enabled. Because this is a change from today's behavior, we highly recommend you make sure this will not cause issues for your existing emails. Same goes for existing Email Templates with custom HTML attributes.
If you omit a DOCTYPE in your Email Template or what you paste into Email Actions > HTML Tools > Replace HTML, the default Marketo DOCTYPE will still be added. You cannot create an Email without a DOCTYPE.
The Email Template "Preview" option will not show your custom DOCTYPE. This is expected so you can disregard this. Your emails will still have the DOCTYPE. This also applies to custom HTML attributes.

Again, please reach out directly if you'd like this enabled starting tomorrow (10/14) for your subscription. We will roll this out to all customers shortly after.

Thanks,

Justin
