Is Salesforce as a destination supported by any chance?

Not today @Dave Lin, Airbyte doesn’t support reverse-etl logic. The answer is valid if you’re asking to send data directly to Salesforce, or there is a backend database used by Salesforce?

Like to write back some basic user data activity back from SQL Server to Salesforce — so marketing department can use that in their outbound marketing.

So Reverse-ETL, this is not supported today.
