On Instagram, the word "inquire" is often used by businesses or influencers in posts that require more information from the viewer. This might relate to a product, service, or event that doesn't list all the necessary details upfront. Phrases like "DM to inquire" or "Inquire for pricing" prompt users to reach out through direct messages (DMs) or comments. It invites potential customers or followers to initiate a conversation for personalized responses. This is especially useful in sales or service-related posts, where the information may vary depending on individual circumstances. Inquiring helps the seller provide relevant and tailored responses.
