In all sending methods of the WebSMS application you can select the landing web saved in the account and in this way add in the text of the message the link associated with the landing.
At the time of sending, the platform will assign to each message a unique shortened link to be able to perform the count and statistics of clicks (How to see clicks received on links?).
It is also possible to use manually (Copy & Paste) the shortened landing link (available in the Editor and in the list of landings).
