Before you start
Things you need to know:
Supported files are HTML, HTM, PNG, GIF, JPG, JPEG, CSS, and ZIP.
Images must be saved locally in the same folder as your HTML file — don't use an Images folder — as this lets the system reference images correctly during import.
The maximum file size is 15 MB for individual files and 50 MB for zip files.
If you're used to designing web pages, note that email HTML can be very different. We strongly advise using tables and font tags in preference to CSS classes where possible to make sure your email renders correctly in different email clients.
Upload a custom HTML email template
Go to Content > Templates > Custom email templates and select UPLOAD TEMPLATE.
If you don't see the option to upload a template, contact us as we might need to activate this feature for your account.
Drag in or select files and relevant images to upload. Files can be uploaded individually, in multiples, or as a zip file.
To view your template, go to Content > Templates > Custom email templates tab.
