For Marketplace sellers

Facebook Marketplace auto-reply that turns inquiries into sales

Buyers message multiple sellers at once. MillionReply answers Marketplace messages instantly with your pricing, pickup details, and shipping rules so you are first to respond and first to close.

  • Reply instantly to "Is this still available?" and shipping questions
  • Close more sales by responding before buyers message another seller
  • Set listing-specific knowledge so every answer matches your inventory

Common searches we built for: Facebook Marketplace auto reply, respond to buyers instantly, and automatic replies for listing inquiries.
