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.
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 100KB and 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, such as excess HTML, text or components.
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.
There may also be instances where images don't display properly and will appear as 'code' instead of the desired image. This will also push out the filesize of your email. You can check this by looking for 'broken' (non-loading) images within your email; you will need to delete them and try inserting them again.
