WSTOOL

Whatsapp has made it extremely convenient for users to talk to each other freely, and all you need is a stable Internet connection, with no other hidden expenses. Given the clear advantages presented by Whatsapp and how it appeals mostly to the mobile devices you always carry around, it is slowly becoming an alternative to email clients around the world. The problem is that the regular Whatsapp client does not currently support bulk messaging, so if that is something you are interested in using, then a third-party app such as WSTOOL is something worth considering.

While you can, in theory, send the same message to multiple contacts in regular Whatsapp, you are limited to how many contacts you can do that at a time, and if you're on mobile, your device might crash when you reach a high enough number. WSTOOL acts like the Whatsapp version of an E-mail bulk message sender, allowing you to theoretically send the same message to an unlimited amount of contacts.

Of course, writing one message and attaching a file is the easy part, but then looking through ten or more contacts (maybe even hundreds) and selecting them as receivers can be time-consuming. That is why WSTOOL allows you to import hundreds or thousands of contacts at once from already existent CSV or TEXT files, and as long as the files themselves are done in a readable manner, adding them becomes easy.

Besides sending an actual message, you can also send attachments in bulk, without any limitation regarding the file format. More so, after you're done, you can clear your entire contact list and import others with just the click of a button, so sending different messages to different sets of contacts is easy.

If you're in a company and would like to send all your colleagues and employees the same message and file, but prefer the more personal approach that Whatsapp gives off, then you'll love using WSTOOL.
