I apologize, but as of my last knowledge update in September 2021, I am not familiar with a specific tool called “WA Sender – WA Message Web Sender.” It’s possible that this tool was developed or released after my knowledge cutoff, or it may be a relatively new or obscure tool.

However, based on the name you provided, it appears to be a web-based application or platform related to sending messages on WhatsApp (WA). It suggests that it might be a tool designed to facilitate the sending of messages through the WhatsApp platform using a web interface.

Without further information, it’s challenging to provide a detailed description or features of this specific tool. If it is a newly developed application or service, I recommend visiting the official website or conducting a web search to gather more information about its functionality, features, and how it can be used.
