Thank you for reaching out to us. I can definitely understand how having access to the HTML of the template can be extremely beneficial. Although there is no access to the HTML in the new Third-Generation Editor, we'd like to know exactly what type of edits you are looking to do so that we can pass this feedback along to our engineers for review. I will also add your account to a track for the request of this feature into the new Editor. However if you'd like to use the older Second-Generation Editor that does contain the HTML access, all you would need to do is to copy over an email that was originally built with the older editor. You can identify these templates with the ''Legacy'' title. I apologize for any inconvenience. Please let us know if there is anything else we can assist with today.
Thanks for that additional feedback regarding the HTML editing options, we have passed this along to our development teams. We do apologize that you aren't able to find what you are looking for when selecting a template. Have you tried searching a specific search term such as "Labor Day". This will bring up specific templates shown below. We certainly understand that campaign design is an option however it may not fit into your budget, as a result we have sent you an email directly to the email on file with more information.
