    Did you hear? We just announced an exciting suite of brand NEW seller tools at PoshFest’s Hackathon! Each of these powerful tools was carefully developed and designed to give our seller community even more resources to drive business growth.

    My Shoppers is one of the three major features in this suite of tools. My Shoppers is a first-of-its-kind, customer-focused tool that enables sellers to identify, engage, and close the sale—including both potential shoppers and past buyers. 


    Poshmark will generate a personalized list of past and potential shoppers based on who have liked, commented, or bundled within your closet. 

    You can filter and sort this list to target shoppers with certain characteristics. For example, you can filter this list based on if you want to see only past likers, past bundlers, or even past buyers. You can also sort based on things like most recent activity, most likes, or most items in Bundle. 

    With these insights on who your shoppers are, you can then perform mass actions on the personalized list to drive those shoppers down the purchase pipeline. These mass actions include:

    Adding shoppers’ likes to Bundle

    Create personalized Bundles for all shoppers at once based on their past likes.

    Sending offers to those Bundles

    Sweeten the deal by offering your shoppers a discount on the personalized Bundles.

    Sending comments to those Bundles

    Close the sale by reaching out to your shoppers directly and giving them great customer service.


    Understand your customers.
    You can leverage information about who engages and purchases from your closet to develop marketing strategies, promotions, and inventory planning. Use your personalize My Shoppers list to:

    1. Dive into customer details: With this list, you can quickly and easily tap through to buyers’ profiles to better understand how long they’ve been on Poshmark, where they live, and more.
    2. See what shoppers are interested in what inventory: Use the customer list and likes information to see what types of shoppers are drawn to what inventory in your closet. For example, new shoppers may shop for certain brands while veteran shoppers focus on others.

    Supercharge your customer acquisition strategy.
    Customer acquisition is the process of bringing new shoppers to your closet and converting them to buyers. You can use My Shoppers to do this by:

    1. Welcoming first time shoppers: You can make your customer service stand out by using Send Comment to Bundle to greet new likers at once and provide information about your closet.
    2. Simplifying the shopping process: Consolidate shoppers’ likes in one place with Add Likes to Bundle, so that you can streamline their shopping experience. Then, use Send Comment to Bundle to initiate conversations with these shoppers.
    3. Providing private discounts: Quickly and easily Send Offers to Bundles to show shoppers that you’re serious about closing the sale.
    4. Follow up to drive urgency: After creating Bundles, use Send Comment to Bundle to let shoppers know that you will be sending exclusive offers with reduced pricing.

    Turn past buyers into repeat buyers.
    Re-engage previous customers with personalized offers and communications. My Shoppers can help you do this through:

    1. Running a win-back campaign: Filter your shopper list according to past buyers, and then use Send Comment to Bundle to give them a compelling offer, such as “I know you’ve purchased from my closet before. As a thanks, I can offer you 30% off of your next purchase!”
    2. Giving special access to promotions: Offer exclusive closet-wide sales for past buyers by reaching out to them via Send Comment to Bundle, such as “I’m running a weekend sale! Add any two items to this Bundle and I’ll give you a private 50% discount.”

    Ebony Beckwith Joins Poshmark’s Board of Directors

    We’re excited to announce that we’ve appointed Ebony Beckwith, Chief Philanthropy Officer at Salesforce and CEO of the Salesforce Foundation, to Poshmark’s board of directors. 

    Ebony brings over two decades of experience in technology, operations and philanthropy. At Salesforce, she’s responsible for the company’s philanthropic investment strategy and leads Salesforce’s community response to pressing issues, including co-leading a task force committed to racial equality and justice. Ebony also has a strong connection to the brand — she is an avid Posher and has been a part of the Poshmark community since 2014. 

    We asked Ebony a few questions about why she’s joining our board, here’s what she had to say:

    Q: What drew you to joining Poshmark’s board of directors? 

    A: I’ve been a loyal Posher since 2014 so I’ve experienced firsthand how special this community is. I love that there’s a strong emphasis on sharing and community building. Even the most successful Poshers take the time to be part of the community. And that’s because they recognize the value to both their business and their relationships with other Poshers. I also admire what Manish has built, alongside an incredible team and board. I believe in their vision and could not be more excited to define the future of shopping together.

    Q: A majority of Poshmark users are women. How do you see Poshmark supporting women’s empowerment and economic opportunity more broadly?

    A: I read a recent report that women’s participation in the workforce is the lowest it’s been in 30 years, which is really scary to think about. COVID placed extraordinary demands on women, particularly mothers, and what they need most is flexibility. This is a huge opportunity for Poshmark. Women can build a successful business on their terms, allowing them to prioritize whatever they need to…whether that’s helping their kid with online learning, or caring for a family member, or attending to their mental health. The future of work is all about balance and that’s exactly what Poshmark can offer.

    Q: What elements of your experience are you excited to bring to Poshmark?

    The world of work is changing quickly, and we’re realizing that areas like philanthropy, CSR, and ESG are no longer “nice to haves” for companies…they are non-negotiable. Employees and consumers expect the companies they work for and the brands they love to step up and help address the challenges we face as a global community. My expertise is in applying a data-driven, business mindset to these areas to drive real, meaningful, and measurable impact for all stakeholders. And those can include our employees, our customers, our communities, our shareholders, and our planet. Poshmark has been community-first from Day 1 so I’m excited to partner with the team to drive its next phase of growth and impact.

    You can hear more about Ebony’s experience with the community from her #MeetthePosher video here.
