I've got a smallish list and go through phases of trying different ways to ... er ... interact.
You see I don't subscribe to the 'you must build a relationship with your list' to make money because I'm on loads of lists where the recipients probabaly haven't a clue who the list owner is.
They just wanted that free report and handed over their email - then get daily offers.
Nothing wrong with that ... it's a business model and it works. Some of my favourite affiliate marketers do exactly that.
Not to mention that it depends on your traffic source and a few other variables.
Anyway ... like I said ... I try different things and ways to communicate with my list to see how my results change.
Last week I got a few replies ... sure my links weren't quite working : ) ... but my list piped up and had a word, they sent me some emails.
It was nice to know they gave a s***.
Some even asked for some personal help. First time it has happened ... it made me feel more responsible for information I send out, the products I promote and the way I treat those REAL people who may well do whatever I say ... just so I can have have another Starbucks (... that's the craze these days ... right?!)
Anyway ... do what you like - it's your business model ... but I think it's changed my outlook. Will be more or less profitable ... who knows but if I end up with skinny kids - you'll probably be able to work it out.
