After doing a bit of research, I was able to find two workflow automation tools that connect with Constant Contact and Infusionsoft. However, neither of those appear to support syncing email statisics from Constant Contact to Infusionsoft. In this case, I think that the only sure method to automate this workflow would be to contract a developer to create the integration on your behalf. Constant Contact's APIs do allow you to access the tracking data from your emails, and I would assume that Infusionsoft has a method of allowing you to import that data with an API.
While Constant Contact does not currently provude custom development services for integration, we do have osme partners that can build out custom integrations on your behalf. You can find them through our Marketplace.
The two automation tools that I found are:
Zapier - https://zapier.com/zapbook/constant-contact/infusionsoft/
Automate.io - https://automate.io/integration/constant-contact/infusionsoft
