Overview
Embedded images in ExSign signatures allow images such as company logos or banners to be included directly inside the email itself, instead of being loaded from an external web link. This helps ensure that recipients can view the images even if external image downloading is blocked by their email client.
This article explains how embedded images work in ExSign, how to configure them, and important limitations to consider.
What Are Embedded Images?
An embedded image is stored directly within the email message rather than being referenced through an online URL.
When the email is delivered, the image travels with the email content, allowing recipients to view the image without requiring internet access to load external resources.
Common use cases include:
- Company logos
- Marketing banners
- Footer graphics
- Social media icons
Important Considerations
Before using embedded images, please review the following limitations:
- Embedded images increase the overall file size of the email.
- Image quality can sometimes degrade after multiple email replies or forwards.
- Some mobile email clients may replace embedded images with cached or unrelated photos, which can result in unexpected image displays.
- Profile images and QR code images cannot be converted into embedded images in ExSign.
How to Configure Embedded Images in ExSign
Follow the steps below to convert an image into an embedded image within your ExSign signature.
Step 1: Log in to the ExSign Portal
Log in to your ExSign Portal using your administrator credentials.
Step 2: Navigate to Signature Rules
Go to:
Rules → Manage Rules
Edit the required signature rule.
Step 3: Upload the Image
Inside the ExSign editor:
- Upload the desired image into the signature.
- After uploading, select the image.
- Click Convert to Embedded Image.
The image will then be converted into embedded format.
Important Note About Existing Images
Images that are already added as linked or externally hosted images will not automatically function as embedded images.
To properly embed an image:
- You must upload the image directly from the ExSign editor.
- After uploading, manually convert it using the Convert to Embedded Image option.
Unsupported Image Types
The following image types cannot be converted into embedded images:
- Profile images
- QR code images
These image types will continue to function as linked or dynamically generated images.
Embedded Image Behavior
After sending the email, the embedded images will be displayed directly on the recipient's end as part of the email content.
This allows the images to appear within the email signature without requiring external image downloads.
Best Practices
For optimal performance when using embedded images:
- Use optimized image sizes to reduce email size.
- Avoid excessively large banners or graphics.
- Test signatures across desktop, web, and mobile email clients.
- Use commonly supported image formats such as PNG or JPG.
Conclusion
Embedded images in ExSign help ensure that important branding elements are displayed directly within emails without depending on external image hosting. While they improve visibility and compatibility in many environments, administrators should also consider the increased email size and client-specific rendering behaviors before implementing them widely.
