Additional Note: You can mask that tracking link and replace it with your own branded subdomain by creating another CNAME in your naming server (done by your IT department). This is the same process as your CNAME for your landing pages, but is a different subdomain (aka CNAME). For instance, your landing page CNAME might be info.company.com and your branded tracking link might be track.company.com.
