If you're seeing an error message when trying to save or send your message it may be that your email is too large or some of the images you're using need to be resized. This article will identify the cause of these error messages and guide you through resolving them.
Please note: In some cases you will be unable to save your message until these errors are fixed.
Message content is too large!
You will receive this error if your message size is above 10MB, you will be unable to save your message if you exceed 20MB (this excludes images in the message). In order to resolve this issue you will need to delete content from your message - excess HTML, text or components are a good place to start.
A message of this size is exceptionally large and it may be worth splitting your content into multiple messages or using external links to more information when using large amounts of text.
Images within the message are too large!
You will receive this error when an image or the combined size of images in your messages are above 10MB, you will be unable to save your message if they exceed 40MB. In order to resolve this issue you will need to resize your images to be smaller or remove some images from your message.
If you need to include very high resolution images consider hosting them externally, with a small thumbnail that includes a link to the larger resolution image or images.
