I have been using constant contact for many many years. Recently, when I upload a photo into an email - it won't show correctly. See picture below. Logos I upload last year come up but logo or pictures I upload in the last month - are not showing up in email.
Thank you for reaching out to the Community about your email! I have taken a look at your account and can see you've also reached out to our Chat Support about this as well. In fact, our support suggested whitelisting Constant Contact. Have you tried whitelisting? Did this make a difference in how the images are appearing in your email client?
I apologize that you are having the same experience! I do recommend white listing Constant Contact and that should fix your issue.
