Pick your Thnks 

Under the contacts page, switch from the Email tab to the SMS tab

You can either input your recipient's phone number in the search bar, or select a contact from the list if you have connected your phone contacts to Thnks. 

Write your message 

Confirm and press "Send" 

Your phone will immediately open up with the text containing your Thnks- from there you can make any final edits to the text if needed, and send! 

Your Thnks will be instantly delivered as a text to your recipient's phone, where they can respond on the chain directly back to you.
