4 ways to send messages on WhatsApp without saving contacts’ number

WhatsApp without contact

Starting a business often involves reaching out to customers (which can be time-consuming during promotions) or customers reaching out to you. 

Each message sent requires selecting a contact, typing out the message, and then sending it - a repetitive process if manually. 

WhatsApp is a handy tool for such communications, both personally and professionally. In this guide, we'll simplify a common hurdle:  How to send a message on whatsapp without saving a number.

Why send WhatsApp messages without saving the contact?

We all know that the need of adding a contact number to send a message, sometimes can make us give up on sending that message, because we don’t want to waste our time. 

As we said above, there are two business scenarios that involve chat in WhatsApp without saving a number: business to a client and client to a business. Let’s explore some struggles of both scenarios, when we thought about WhatsApp without saving contact:

For you company: Your company is growing and you’re generating a lot of leads, and now you can’t handle adding all your clients contacts one by one, to send them marketing messages in the future.

For you clients: Nobody wants to waste their time, and the need of adding your WhatsApp contact, can mean losing a sale. The client can be interested in your product, but if he can’t chat in WhatsApp without saving a number, he might give up on the purchase.

Both situations have the same thing in common: they can make you decrease your sales profits. And that's why now we’re going to teach you ways to send WhatsApp messages without saving contact, for you and your clients.
