The customer support team has been very responsive throughout our engagement with them (and their predecessor). They are always willing/able help us troubleshoot issues when they arise during implementation or after launch of product features we need assistance in implementing / using effectively - this was not something I had heard about from other vendors that have implemented similar products but it's definitely important as you can't afford downtime! It would be helpful if there were some additional training content available beyond what comes out-of box which could provide more insight into how best users should use certain functions within Product interface etc., however overall experience so far hasn’t really given me any reason why i wouldn; t recommend going ahead wif my business partner & ; CMOs recommendation.- Tracking open rates across multiple inboxes at different locations,- Sending emails via API integration:- Sender Analytics reporting capabilities.
