Thanks for reaching out about this and we're sorry for any confusion. All of our email templates are readily available and readily editable! When selecting a new email template, or copying a sent email campaign the result is a brand new draft for you to edit. As Evan previously mentioned the option to save an email campaign as a template isn't currently available in our new Third Generation Editor. However, we are collecting customer feedback about this for our programmers and I've submitted yours.
Is it true that there is no way to open a template, makes changes to it and save it?
If there is a way to do this, please provide the steps.
You are correct, at this time being able to save an email campaign as a template isn't currently available in our new Third Generation Editor. This is a feature request we have submitted in your account to the appropriate teams. However as a workaround you can make changes to your template and continue to copy this template for future emails. You can also put your template into a folder for easy access!
