Two weeks ago, we created an email with a script token for a custom object field containing a unique registration url. Of the 208 emails sent, 12 recipients replied indicating the url didn't work. The team created a my token at the program level (see below) and used the my token in the tag. The field in sfdc is an url field with the 'https://' already appended. Here are my questions (please remember I am new at this):1. It seems velocity script can become disconnected from the custom object, could this be the case here and only for a select number of persons?2. Is there a better way to handle urls in velocity scripts? From the reading I have done, it seems reconstructing the urls may be a good way to go? Please keep in mind in the current set-up all I have in the full url being pushed from sfdc3. Velocity scripts don't work in the sampling feature, correct?Script token details: ${CRLC_Application__cList.get(0).RSVP_Link__c}Token name: my.CRL-RSVP-Link{my.CRL-RSVP-Link} was hyperlinked

Is there any way to collect the browser type (Chrome, IE, Safari...) from the IP? Thank you!
