That is why WhatSender 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.īesides sending an actual message, you can also send attachments in bulk, without any limitation regarding the file format. 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.

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. WhatSender 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.
