Tokens for specfic document download links based on email address

Unless you have already segmented by email domain (which is going to be impossible if you have > 100 domains and 100 different documents) you must use Velocity.

You don't need any separate tokens but a single Velocity token like so:

#define( $formatLink )<a href="http://${document}">Click to get your document!</a>#end
#set( $documentDomainMap = {
  "googlemail.com|gmail.com" : "www.example.com/google.pdf",
  "yahoo.com" : "www.example.com/yahoo.pdf",
  "hotmail.com" : "www.example.com/hotmail.pdf",
  "" : "www.example.com/default.pdf"
} )
## No need to edit below this line!
#foreach( $domainList in $documentDomainMap.keySet() )
#if( $lead.Email.matches( ".*@(${domainList})$" ) )
#set( $document = $documentDomainMap[$domainList] )
#break
#end
#end
## Use default if domain not found
#if( !$document )
#set( $document = $documentDomainMap[""] )
#end
${formatLink}

As you can see, at the top of the code, you list the domains (the $documentDomainMap variable that maps domains to their documents) and you set up the final output link (<A> tag). You don't need to edit anything else. Also note the domain can be a pipe-delimited list of domains (if some domains will get the same document).

When you create this token make sure Email Address is selected in the right-hand tree (if you don't do this then Velocity can't see the value of lead.Email).
