Whilst I realize promoting (or even mentioning) on BL that you have a store here, will get you the boot from BL (for TOS violations)
Is there anything in their TOS that says that you may not make a mention of Brickowl AFTER a sale on B/L (direct to buyers email address NOT via BL messages)?

/I will not sell outside of BrickLink, but I do sell on eBay (billundbricks77), so please do not ask./
I never saw BL have a problem with this. (His store is currently closed)
I think that the best way to promote your store through your BL orders would be with an enclosed note to your buyers stating that you sell on both sites. I don't see how they can stop you from including anything like that in your orders.
Just my observations only,
