Just curious what the consensus is on the length of urls in the email body. Shorter the better? Is there a character limit you try to stay under? Currently I have links that look comthing like: http://click.somedomain.com/XRudGJuamkA8BP4if35j7y08Eb4Z9ZIVaOz9jdao4J59aMUojepHsOOFSsgJ608... up to 100 + characters Would it be better if I had something more like: http://click.somedomain.com/rd?x=gQzy0 Just to be clear I'm not talking about using a public url shortening service. curious on everyone's thoughts and if it makes any difference or not with regards to filters, etc..
