If your contacts are telling you that they're receiving your email but content isn't displaying properly, a good place to start is to have them check the settings in their email client to make sure that their settings enable images to display. If that doesn't help, the next step is to have them check their browser to make sure it isn't blocking the images:

If your contacts' email settings and browser settings aren't fixing the display issue, try having them add Constant Contact's URLs or IP address to the safelist of their security program.
