About Email Images


One of the magical features in FeedOtter is its ability to automatically pull amazing images for all your content. We do this in several ways but there are a couple important things to consider to ensure FeedOtter finds the image you expect.

FeedOtter Looks for Open Graph Image Tags First(og:image)

Open-Graph or OG tags are a web standard created by Facebook as a standard way to display the common properties of a webpage when a URL is shared. The most common properties are: Title, Description, Featured Image.

FeedOtter embraces this web-standard and looks for an og:image tag as the first source of a featured image of an article. If an og:image value is found and the size of the image if of high enough quality to be used in an email, FeedOtter will display this image.

To learn more about Open Graph tags continue reading here:

  • Using the same aspect ratio for all your featured images requires team discipline but will keep your images looking consistent across the web and in your FeedOtter emails.

  • FeedOtter will use the exact image URL found in your OG:IMAGE tag as the SRC value in your email. This is called a "hotlink".

  • The best way to control which image FeedOtter displays in your email is ensure all of your content have OG:IMAGE tags.

Image Crawler

If your article does not have an OG:IMAGE tag. FeedOtter will crawl your article page and look for a quality image to display in your email. We have special logic here that looks for images of suitable quality and placement.


Certain FeedOtter email templates make use of a special feature that allow you to crop/resize the images used in emails. This is done to make images look consistent regardless of the source image's aspect ration or resolution.
