I do understand that Pardot is a great product and it is a Salesforce product.
Currently we are using Constant Contact for Marketing and Communications.
We are in the initial stages of SF implementation process. I am trying to decide on the reasons to switch to Pardot and reasons to stick with Constant Contact.
Could you please share your experiences.
Thank you!

@Courtney Bethem Phillips Our email needs are more focused on organization relationships rather than Households/donors. But all of our Contacts live in Households and are related to those other Accounts via the affiliation/junction object. So although Pardot can look at the Household data easily (1 level removed from the Contact), the data we'd want to segment on/include in merges is actually 2 levels away. We've found workarounds, but it wasn't something we had anticipated at the time.
