We have recently integrated a couple of free stock photography sites in to our email editor.

When adding images to your emails you can now search both Pexels and Unsplash from within the editor

Just click the Search Online button and enter your keyword in to the search box. eg Food

A paged set of results appears

Select the image you want by clicking on it and it is automatically downloaded and resized to fit your email template.

It is as simple as that.
