Communication on Swappa takes place before (pre-sale) or after (post-sale) a purchase.

• Pre-sale communication: Buyers and sellers can communicate about a listing in the public comments on listing pages. All comments should directly pertain to buying and selling that particular listing.
• Post-sale communication: After a listing sells, buyers and sellers can communicate directly on their private sale page.

The exception to this rule is for Enterprise Sellers. The public comments for enterprise seller listings are disabled, and Enterprise Sellers can only be contacted post-sale.
