Yep, oneeyejack got it! The starpoints will post directly into your SPG account from your spend on the Amex SPG. If you want to transfer your Starpoints to DL, you'll get 1 DL skymile per Amex SPG. Unless you transfer 20k (or 40k, 60k) over. Then, you will get a 5k (10k, 15k) bonus.
With that said, why DL? Are you finding a redemption that works really well on DL but not so well on other airlines? I think that more often than not, your starpoints are better sent to AA than to DL, since the transfer ratio is the same, and AA miles will generally get you farther
