I was with another service and switched to Constant Contact....I like the Constant Contact for many reasons over my previous service, but have a major concern. For effectively the same list on my old service, I had a bounce rate of about 200-250 address...using effectively the same list on Constant Contact...my bounces jumped to 778 bounces!!!! Nearly half of those were "blocked" It makes me wonder if Constant Contact's IP address is more likely to be blocked on more servers for spamming. This could be a big concern for me. They are mostly unique domains (not Gmail, Yahoo, or MSN accounts), with generally business email addresses. It would be very labourious to email each and every of the 300-400 blocked emails to get ask that they unblock. Any thoughts??? Any tools that I can use to see if it is your IP address causing it or whether it is something else?
