As a message composer, I want my links in the message to be automatically UTM tagged per each channel. When I paste a link into the message, I don't want to spend my time on selecting a right UTM template per each link. I want to have an option to have it done automatically for me. For example, if I create a message and select FB, Twitter and LinkedIn channels, I want each of the links to be automatically adjusted with relevant UTM tags from my templates. Buffer already offers this feature, so it must be easy :)
