Do it inhouse


我曾分析过 outsourcing seo 服务的弊端,here is another negative case of outsourcing email marketing.

I received a newsletter from Tesco today, and happened to click on one of the embedded links. (I am not a newsletter reading fan. I seldom click on embedded links.)

I got a “404 Not Found” error when I natigated to that url. After a few seconds, I became aware Tesco link tracking system is hosted on, which is on my black list. I assume Tesco have a third party doing email marketing for them, otherwise Tesco on their own have no reason to use as a click tracking provider.
