Using your image and document libraries

We provide free storage space for your images and documents. Use the image library for quick access to image files you use regularly in your mailings, and use the document library to store files you want recipients to be able to download, like an attachment.

Using your image library

Your account comes with an unlimited image library to hold images you use regularly in mailings. You don't have to store images in your library in order to upload them to a mailing, though. You can also upload directly from your computer, or from your Facebook or Flickr account. Your image library can store the following file types:

  • .jpeg
  • .gif
  • .png

View your image library in one of two ways

Head to your Campaigns page, and click the Images button in the left sidebar. Once you're seeing your images, you can use the drop-down arrow to the right of each file to download, copy the URL of the image, or archive it. If you want to upload more, look for the Upload option toward the top-right side.

Click on an image placeholder in the mailing you're already working in. In the window that appears, click on the Library tab to navigate your stored images, or upload a new one.

Deleting old files from your image library

You can delete an image file by clicking to open your image library, clicking the downward-pointing arrow to the right of that file and selecting Delete this image.

Retina image support

Retina, or high-density, displays produced over the last few years can render images with a much higher pixel count than older displays. This creates an opportunity for much sharper and clearer images displayed in email.  

Luckily, high-density display support for images in email is automatically baked into the Emma application.

To take advantage of Emma’s high-density display support, you’ll need to ensure that your images are uploaded at 1280 pixels wide or larger. This is double the size of the largest photo you would need for a mailing, since a photo stretching the full width of a template would be a maximum of 640 pixels. At the time of send, we’ll do the math for you, downsizing your photo to no less than double the size of the image placeholder you’ve designated. Retina displays take advantage of the extra pixels and display a sharper image as a result, ensuring that all your images will look sharp on high-density displays.

If you’re not able to upload high-res images, that’s okay. Your email will still render fine on all clients, but images may look somewhat “blurry” on high-density displays.

How do I resize my image?

The key to supporting images on retina displays is to use images that are twice the size of the intended image size. If you want your image to be 200x200 pixels in your mailing and you want it to display clearly on high-density displays, you’ll need to upload that image to the mailing at 400x400pixels. To size your image up, you’ll want to export a larger version from the original image source. Using an image editing program to simply increase the image size will result in a blurry image.

Color model

Your images need to be in RGB color values, as opposed to CMYK color values. CMYK color values are for print and won't render in an online environment.


Using your document library

Your document library allows you to save your files to our server (up to 50 MB) and link your recipients right to them. It's a safe alternative to attaching a file directly to the mailing, which can cause the entire email to be blocked by spam filters or firewalls. Here's a list of file types that you can store in your document library:

  • .txt
  • .rtf
  • .vcf
  • .xpo
  • .ogx
  • .pdf
  • .xls, .xlsx
  • .doc, .docx
  • .ppt, .pptx
  • .ics
  • .swf
  • .mpeg
  • .m4a
  • .wav
  • .mp3
  • .mov
  • .flv
  • .avi
  • .asf

View your document library in one of two ways

Head to your Campaigns page, and click the Documents button in the left sidebar. You'll see your documents appear on the right and you can click on any document name to view the file or copy it's URL.

Click the Insert button on the editor toolbar in the text box you're already working in, and select Link, and then click Document in the window that appears. Use the dropdown menu to view your list of stored documents or upload a new document.

Deleting old files from your document library

If you reach the 50 MB limit, be sure to delete old files to make room for new ones. (With cloud storage, you don't need to worry about deleted documents you're linking to no longer working from mailings you've already sent.) You can delete a document by clicking to open your document library, clicking the downward-pointing arrow to the right of that file and selecting Delete this document.
