I've just spent an hour messing about in my email system trying to figure out where on earth a bunch of visitors to my website are coming from.

I'm getting a regular stream of signups to a little automated webinar I set up a while back that runs once a week. The webinar is a good one, and I make sure I'm available when it's running to answer questions live.

The problem is, I thought I'd shut it down.

It promotes a program I no longer offer. So (I thought) I removed all the emails that promote it from my system.

Yet I'm still getting a signup a day on average. 

Somewhere there's still a signup link in my system. Yet for the life of me, I can't find it.

The root of the problem is that I over-complicated my system.

It's easily done. You think you're being clever. You add something in for every eventuality. You add an advanced version. You add in an extra bit in case people don't go for the first one. 

And before you know it you've got something so complex you can't even find the emails people are clicking to register for your defunct webinar. 

80:20 really does apply to your marketing. All the extras I added took a ton of my time but they really only added marginal revenue. 

They made me feel clever (at least until I couldn't find the offending email earlier today). But they didn't add much to my bottom line. 

You don't need the fancy stuff. Stick to the core.
