Currently you can only send templated messages to contacts. However I use WhatsApp to communicate with some of my clients normally, just as with SMS and email.

It would be great if we could just send normal messages to our clients through WhatsApp and not be required to use a template.

For example a client just sent me some files for a project. I would like to send a simple message of "Thank you , received" but I cannot do this unless through a template.

Very frustrating to not be able to do normal client communications through this channel.
