How to add and edit images using the file manager

Your File manager is where you store all the images that you upload and use in your campaigns and forms.

The file manager is accessible from your right-hand drop-down menu.

Here, you can click the orange Upload image button to import an image from your computer into your file manager.

Alternatively, you can click the downward-pointing arrow on the right-hand side of the button to import an image from a URL, Google Drive, Giphy, or Unsplash.

If you select URL, a window will appear. Paste the URL of your chosen image into the input field to import it.

If you select Google Drive, a window will appear that allows you to log in to Google Drive and select images directly from your drive.

Unsplash is a great website used for sharing stock photography. You can choose from over a billion images that can be used in your newsletter for free.

Giphy is a similar resource. Though, rather than supplying an endless library of static images, you can choose from a huge range of GIFs to add to your newsletter.

Check out this guide to using GIFs in emails if you’re interested in using GIFs in your next newsletter.

Larger images load slowly in your subscribers' inboxes. Also, if they're using their mobile internet, larger images result in bigger data usage.

Additionally, the smaller the image, the less likely your newsletter will land in spam or the promotions tabs.

For this reason, your images must be under 2 MB.

If your image is too large, you can use an external tool to compress the image.

To add an image directly to your newsletter, first, drag the image block of your choice into your newsletter template from the left-hand sidebar.

Then, click the image block and press Browse in the right-hand sidebar.

This will open your File manager. From here you can select an image you have already imported, or you can upload a new image to add to your newsletter.
