How do I create a campaign using a template designed with the HTML editor?

You have 3 options for email design using the HTML editor.  We'll cover these below.

Note: HTML templates, pasted HTML code, or uploaded HTML files are not compatible with the drag-and-drop editor, therefore you will be taken to a WYSIWYG editor instead for editing.

How-To

Create a campaign from a stock template

1. Navigate to the Campaigns dashboard. Create a new campaign using the action button at the top-right.
2. Complete step 1 of the process by assigning your campaign name, subject line, etc. Click "Save and Next".

4. Click "HTML Editor Stock Template" button at the top of the pop-up.
