Reviewed the Wiki article

Apart from the above do you have any additional Inputs or documents where I can see the features supported by Acumatica?
I want to understand what are the features that can be used in Acumatica with send grid.
There are a few questions from our customer
how do we send marketing campaigns out of Acumatica using sendgrid?
how do we get the click data into Acumatica?
can we create a marketing campaign in sendgrid, send it out of sendgrid and have that data, and campaigns go back into Acumatica.
