More than 50% of images in promotional emails are routinely blocked by email and webmail programs, but many marketers are still sending image-based emails that do not render well as text-only.

Most retail email marketers (57%) send largely image-based emails, even though they have higher spam scores (and so are more likely to be blocked by spam filters) and have lower open and response rates.
