Another good reminder to test your email campaigns prior to sending them out... As an example, Old Navy recently sent an email that had two prominently displayed broken images near the top.

I would highly recommend a "QA Checklist" for any email marketer to ensure the email campaigns they are sending have the highest quality.

A quick starting point:

• Ensure all links are clickable and arrive at the intended destination
• Ensure all images render
• Ensure overall message format appears appropriate in different email clients and browsers
• Ensure overall rendering speed for the message is good for high-bandwidth and low-bandwidth subscribers
• Ensure appropriate footer including CAN-Spam language is included

Below is a screen shot of the broken images:
