Why are email signature images not loading automatically?

Use this article to understand why images in your email signature - such as your logo, personal photo, or social icons - may not display automatically, and learn how to configure your email client or mobile app to load external images automatically

Written by MySignature Support

Why do images fail to load automatically?

Images in an email signature typically fail to load automatically for two main reasons:

  • Plain text email format: Some messages are sent in plain text instead of HTML. Plain text does not support embedding or viewing images, so all images are automatically converted into email attachments instead.

  • Blocked external images: Email clients, webmail services, and mobile apps often block external images (images stored on a secure online server) by default for security and privacy reasons.

To view external images automatically, enable automatic image loading in your specific email client, webmail service, or mobile app using the instructions below.

  3. Scroll down to the Images section.
