I’ve been updating my email address to many newsletters since I changed ISPs. Look at your newsletter. If the user has to unsubscribe and then resubscribe to your newsletter the user may not resubscribe. All I want to do is change the email address. Several newsletters and web sites make it very confusing. A user should not have to try many different things to change an email address. One site hid the change email address button under the New tab, that was a low blow. It may have made sense to the programmer but not to me.
If the web site or newsletter made it very difficult to change the email address then I thought very hard about how much I wanted to get the newsletter. I now do not subscribe to several newsletters since it was to much effort to resubscribe.
I’s called voting with your feet, so go make tracks people.
Write on, draw on.
