We installed PosherVA and tried all the features. Compared to PosherVA's sharing and follow features, PoshMarvel allows you to target buyers and acquire followers more efficiently.
PosherVA is a browser extension. We were able to install and register without any problems. It has all of the standard features, share, follow, like, offer, bulk price editor, activity returner etc. All the features run in the background, which makes it hands-free but creates some confusion about the tasks running and progress. There has a single paid plan of $25 per month. In addition to the paid plan, there is a free forever plan that is limited in number of shares and follows. It is a starter plan which is useful if you have a small closet. The trial doesn't require a credit card which makes it easier to test.
When a CAPTCHA occurs, it automatically solves it. There is a limit of 20 captcha per day which is more than sufficient. We didn't see any problems with sharing and following, it works as expected, activity log tracks progress. However, these features are very limited in getting you new followers. It expects you to know which closets to follow, which searches to run etc. Some features need the user to be on a certain Poshmark page, extension doesn't directly navigate'. This creates confusion. In addition, the extension doesn't stay on top of the page therefore we had to keep clicking the extension's icon at the Chrome bar. Below are some unique features.
