Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.
It looks like we've already followed up with you via email, but here is the information provided for visibility on the forum:
In regards to there being an easy way to pull email campaign reporting information, that would all be dependent on how the CRM has their integration set up to pull in Constant Contact campaign reporting information. If you're currently in the process of determining what CRM you'll be selecting, I would recommend asking if they have an integration with Constant Contact or if they have a way to pull information into the CRM via an API. Below is a link to documentation on email campaign reporting with our API. This documentation may be useful while you're still looking into CRMs.
