Hosted or Linked images

A hosted image is stored on a server and linked in the email signature. Instead of being added as attachments, these images are downloaded from the server when the email is opened. This approach reduces the overall size of the sent email

Benefits of Hosted Images

  • They bypass antivirus blocks, ensuring successful email delivery.
  • Linked images do not increase email size, reducing the risk of rejection by email clients.
  • Avoids additional attachment files in received emails compared to embedded images.
  • Easily find out who received your email by analyzing the web traffic for the linked images in the message

Limitations of Hosted Images

  • Some email clients may not show images automatically, requiring recipients to click a ‘Download Images’ button or adjust settings.
  • Recipients need an internet connection to view the images, as they are directly accessed from the linked URL.
  • If the linked URL becomes inaccessible or is changed, the display of signature images may be affected.
  • You must use an SSL-secured server to host your graphics files

Embedded images

An embedded image is attached to the original message and becomes a part of the message body. In contrast, a Hosted image is not directly attached but is linked externally. As a result, embedded images tend to be larger in size because they are included as attachments in the sent email.

Benefits of Embedded Images

  • Images will be displayed automatically when the email is viewed.
  • You can view the images even when the email client is offline.
  • Recipients don't have to download images manually.
  • Images remain unaffected by accidental deletion or changes in URLs or server accessibility.

Limitations of Embedded Images

  • Some email clients may reject the email or block it due to antivirus software.
  • Directly embedding images into your signature increases the email size, which may lead to rejection based on size limits. Sigsync will not embed images if the email size exceeds 19MB by default, for a safer approach.
  • Certain email clients may convert embedded images into attachments, which can affect the signature display.
