What Is the Difference Between Logging in Salesforce via BCC and API?

[#1]

Logging with Salesforce via BCC will auto-append this BCC to every email you send out with Tout functionality (as long as this BCC is saved here)

Any emails sent to persons not saved within your Salesforce will automatically be assigned to 'My Unresolved Items'*

*if you have the 'If no matching records are found, create a task for each recipient and send it to My Unresolved Items' box checked here

Logging with Salesforce via API will make sure we show live Salesforce data in across the application and log all of your emails automatically into Salesforce

NOTE: Make sure these ToutApp settings match with your Salesforce settings

Any emails sent to persons not saved within your Salesforce will automatically be assigned to 'My Tasks'*

*if you have the 'Create an Unassigned Task (tasks will appear in the 'My Tasks' section of your 'Home' page in Salesforce)' box checked here

NOTE: This setting will override the 'If no matching records are found, create a task for each recipient and send it to My Unresolved Items' checkbox Salesforce setting
