Did you know you could combine our short url feature in Quick SMS with placeholders?
Simply create a contact list and add the path in the custom fields to get a unique link sent to each contact.
For example, your message could be
Hello! Check out my video at youtube.com(Cust. 1)
and in the contact list, have the value for custom field 1 be
/watch?v=j4RJMeP-jlk
If you've sent the message with the shorten-urls toggled on, the recipient would receive a message which then redirects them to the link of your choice.
