Once you choose SMS as a channel to send a message, you will see a counter indicating how many characters have been written. Once a message is sent or received you will only be able to use that method to respond to your customer, you will not be able to switch between text and email. You can now choose to send a message via email or via SMS text message within the inbox via message or from within the client conversation screen. If you do, you have two different ways that you can send a message. You will need to ensure that you have a mobile number for the contact you would like to have a conversation with. Once you see that the "Register" button has changed to "Verified", you can now send and receive SMS messages through your Thryv Inbox. In these cases, you will receive an error message (explained later in this section.) There are also certain phone number providers that do not allow Thryv to text enable their number.

Note: You cannot use a Google Voice number or a mobile number. Input your business landline phone number on the space indicated and click "Register". Simply go to Settings>Auto Client Messages >SMS Settings: What magic is this?! We're about to tell you. With Thryv, you can enable your landline to start sending and receiving SMS messages with your customers!
