Four platforms, four completely different message habits
Poshmark buries private questions under share activity. eBay ties messages to formal case deadlines. Mercari holds your payout until the buyer rates the order, which makes a slow reply an actual cash-flow problem, not just a manners issue. Depop moves like a group chat, with offers and casual DMs blending together. Treating all four the same way — or worse, checking them one at a time, in whatever order you happen to open the apps — is how good questions get missed.
What one inbox changes
Closetline pulls messages from all four into a single queue, sorted by what actually needs a reply next rather than which app you checked most recently. An eBay case nearing its deadline shows up ahead of a Depop DM that can wait until tomorrow, regardless of which platform either one came from. Every thread carries an AI-drafted reply, the buyer's order history with you, and the item photo, so answering takes a read and a tap — not a hunt through your listings.
Nothing sent without you
Closetline drafts, you review, you copy the reply into the actual marketplace and confirm it sent. That's the same mechanic across all four platforms — no exceptions, no automated sends, your account and your voice every time.
If Poshmark, eBay, Mercari, and Depop are your core four, they deserve one inbox instead of four separate ones — that's what Closetline gives you.
