Hi Deepak. Thank you for reaching out. We are currently working on an S3 as a destination solution. Updates to this solution are provided on this thread. 

We don't have an exact date for when the private preview will be available to a wider audience at this time. To be honest, S3 as a Destination has presented some unique technical challenges that we are still sorting out. But we're committed to getting it right.

We understand that this destination is important to you, and it's important to us too — that's why we want to make sure it works the way you expect it to work, before we release it. 

If you're interested in joining the private preview, reach out to your account manager / SE / SDR. Once we have a more definite release date, you'll be the first to know. Thanks!
