Today I just started to use an email box that has been inactive for about two years. I mean it was disabled and no mail was delivered to it. I setup my Outlook and downloaded all email received for about two days. This is when my box was enabled again. At my surprise in total 6 emails I had two that were a subscription to some newsletters I have made before. It seems that these newsletters never made an effort to check if their emails get delivered at all. What was more frustrating is that I started to receive spam in the very same day. What a grip. Similar to newsletter administrators, spammers never make an effort to check if the collected email is still valid and if the message is sent at all. But this time they do it for a reason.
