Error: Unable to complete request. Reason: An unexpected error occurred

I can't save or send a test email with a new mailing template, and I get this error: Unable to complete request. Reason: An unexpected error occurred. If the problem continues, please contact your system administrator.

This error can occur during repeated edits when a link markup is accidentally placed between image opening and closing tags, which prevents the system from saving or sending the mailing.

There are several reasons for this error.

Image in the email has incorrect markup

One reason why this error occurs is that an image within the mailing has incorrect markup.

To resolve this error, remove the following markup from the image link:

<img src="http://www.silverpop.com/images.jpg" xt="SPCLICK" />

Source code copied from another template

This error often occurs when you copy source code from one template to another. Images within a mailing template in Acoustic Campaign are assigned unique HTML attributes that are dynamically created for images that are hosted within Acoustic Campaign. This reference can cause issues if you copy from one template into another, as Acoustic Campaign cannot create a reference for the image.

Complete the following steps to resolve this issue:
  1. Right-click the image and select Edit Image.
  2. In Image Properties, select Upload Image > Locate.
  3. Upload the new image from your hard drive, the Asset Library, or the stored files area.
Note: These steps must be taken to replace each image that was copied from another template.

Unable to save mailing template; value too large for column

This error indicates that one of the URLs in the mailing template exceeds the character limit for the href value.

To resolve this issue, go to Source view and search for the URL href tag. Then, shorten the URL.
