Once you have earned your customer's respect,  they start depending on you for good honest recommendations and advice.  You absolutely must keep your standards high in order to keep your customers, especially if you are selling IM programs and software.

True of everything. However, it's just that in IM, people are on en guard for slimmy, skanky, scammy, spammy dime a dozen marketers.  Be careful what programs you recommend. Some of them can get you into trouble.

You have to keep delivering on your promise. What happens if you let people down? They unsubscribe.

Can you blame them? Most of our inboxes look like Times Square at rush hour. Sign up for a free offer, and before you know it, all kinds of offers flood your inbox. Nobody has the time to accommodate that amount of mail. Can't possibly read it all.

So what's the logical next step? Unsubscribe to email that is sent too often, is too salesy, too promotional, phony and just doesn't deliver on the promise.

It's nothing personal. It's just inbox survival.

If someone sends me too much email, I unsubscribe because I know they are just sending offers, hoping some of it will stick. The marketers who send me thoughtful email, but not 3 times a day, and not always with an offer, get my ear.

I'm learning as much from the wrong way of doing things as the right way.  

Try to model myself after the people I admire and well, sort've trust.
