It's very easy for me as it has been able, so far at least! I have had no issues with this software or any of its functions when compared against other similar products out there in terms off ease/speed etc..
There are some features that could be improved upon but nothing majorly negative about what we've used thusfar (aside form not being fully functional yet). We use AdVendorium mainly because they were one of our first partners who supported us after moving over onto AWS & using their API rather than directly integrating into Salesforce via Pardot - which was more expensive initially due to integration costs associated wtihout support by them later down the line.).
