Pass URL Variables

[ImpartialGeek]

I am trying to figure out how to pass user variables in URLS that I can link them to. For instance, I would like to be able to create a link that I can send in an email with variables so that if they click, it goes to their profile. I know I can do this in the IPS bulk emailer, but I am using a 3rd party email platform.

I tried this, but it didn't work: https://cre8live.com/profile/{member_id}-{member_name} 

Any ideas? 

Thanks!
