How to Get Notified of New Poshmark and Mercari Listings

What Poshmark's saved search actually does

Poshmark lets you save any search — including size, brand, color, and price filters — by tapping the star icon after you search. That part works well.

The catch is how you find out about new matches. Saved searches show a red dot in your Saved tab when there are new results, but that's a passive indicator, not a push notification. You have to open the app and check. Poshmark's push notifications are built around social activity — follows, likes, comments, Posh Party invites — not new inventory hitting a saved search.

Trade-off: great filtering, no real urgency. If you're not opening the app every 20–30 minutes, you're finding out about a fresh listing whenever you happen to check.

What Mercari's saved search actually does

Mercari's saved search goes a step further — it can send push and/or email notifications when new items match, depending on your notification settings under Profile > Settings > Notifications. That's closer to a real alert.

In practice, the email version tends to arrive as an end-of-day digest rather than the moment a listing posts, and push timing varies by how often Mercari's backend batches new-item checks. For a $15 mug, that lag doesn't matter. For a pair of grail sneakers or a discontinued handbag, it can be the difference between buying it and reading a sold listing.

Trade-off: real notifications exist, but the speed isn't guaranteed, and there's no way to tighten the check interval yourself.

Option 3: RSS or IFTTT

Unlike Craigslist, neither Poshmark nor Mercari publishes an RSS feed for search results, so the RSS/IFTTT workaround that works for Craigslist doesn't exist here. Some third-party scraper scripts exist on GitHub for Mercari specifically, but they require running your own server or scheduled job, and they break every time Mercari changes its site structure — not a realistic option unless you're comfortable maintaining code.

Option 4: A purpose-built alert tool

This is the gap tools like Botifex are built for: monitoring Poshmark and Mercari (plus Craigslist, eBay, Facebook Marketplace, and OfferUp) on a fixed schedule — every 5 minutes on the Pro tier — and pushing a single alert stream instead of two separate app-native systems with two different notification behaviors.

Disclosure: this is our tool, so take the recommendation with the grain of salt it deserves. The honest case for it here specifically is consolidation — if you already run saved searches on eBay and Facebook Marketplace too, checking four apps with four different notification rules is the actual time cost, not any single platform's speed.

What we recommend in 2026

• Casual shopper checking once a week → native saved searches on both apps are fine
• Poshmark-only closet flipper → turn on the red-dot habit, check twice a day minimum
• Mercari-only flipper → turn on push notifications, don't rely on the email digest alone
• Cross-platform reseller (Poshmark + Mercari + eBay, etc.) → a single alert tool that covers all of them saves the most time

How to set up a Poshmark saved search step by step

Start from a real search, not a guess. Search your brand or item, then apply size, color, and price filters until the results look like something you'd actually buy.

• Run your search with size, brand, and price filters applied
• Tap the star icon in the top right to save it
• Open your Saved tab and check for the red dot daily — ideally more than once
• Keep filters specific; "Levi's jeans" produces far more noise than "Levi's 501 29x30"
• Delete or pause searches for sizes or brands you've stopped sourcing

How to set up a Mercari saved search step by step

• Search your item with size, brand, and price range set
• Tap "Save this search" from the search bar or results page
• Go to Profile > Settings > Notifications and confirm push and/or email are turned on
• Don't rely on email alone if speed matters — push fires closer to real time
• Review your saved search list monthly and cut ones that haven't produced a buy

Why fashion resale alerts are harder than furniture or electronics alerts

A Craigslist alert for "Dewalt drill" or an eBay alert for "iPhone 13" is a fairly clean match — model numbers don't lie. Poshmark and Mercari alerts are messier because the same item can be listed a dozen different ways: misspelled brand names, size listed as "M" instead of "8," a colorway described as "sage" by one seller and "olive" by another.

That means tight keyword alerts on Poshmark and Mercari require more trial and error than they do on marketplaces selling standardized goods. Expect to refine your saved searches over the first few weeks — add common misspellings, try both size formats, and watch which keyword combinations actually surface the items you want.

The best alert setup for closet flippers

If Poshmark and Mercari are your main sourcing channels, the goal isn't just seeing that an item exists — it's seeing it early enough to message or buy before another reseller does, since both platforms move fast on underpriced name-brand items.

• Build 5–10 saved searches around brands and categories you actually understand
• Use both size formats (numeric and letter) where the brand is inconsistent
• Set a realistic max price so you're not alerted on items with no margin
• Turn on push notifications everywhere they're available; don't rely on digests
• Revisit and prune your searches monthly so noise doesn't drown out the good alerts
