There’s spam on the Internet, alright. Lots of it. You receive spam when spammers get hold of your email address. How do they do this?
- A friend of yours got himself infected with a virus/worm/trojan horse. This virus reads your friend’s address book and sends all email addresses in it to a spam server.
- Spammers try to guess common email addresses, like
A lot of websites require you to give them your email address.
You can’t really do anything about point 1. You can kick your friend’s butt for not having an anti-virus program running on his computer or for surfing on suspicious websites. But then (in most cases) it may not be his fault altogether.
You can avoid the problems of point 2 by not using so commonly used email addresses (but this may not be possible for everyone).
What this article is about is point 3.
Before we get started, here’s some good advice (not really related to what’s following):
The Concept ∞
How do you cope with point 3? Easy:
You provide a different email address for each website that requires an email address.
Doing this has several advantages:
Although this concept is nice, there’s one big requirement for it:
Creating and deleting email addresses must be extremely easy/fast. Otherwise you won’t do it, trust me.
So, how do we do this? We use a so called catch-all email address.
This requires that you have the ability to create such an email address. Your best chance is if you have your own domain and your domain provider allows it.
- Create a sub domain for these email addresses. (Don’t use your TLD if you can because a sub domain is not that easy to guess.) For example, create
- Create a catch-all email address for this sub domain. This can either be a mailbox or a forwarding.
Now, when register at a website called “my-fancy-shop”, use
firstname.lastname@example.org as email address. “Creating” a new email address couldn’t be easier, could it?
If you want to delete/block an email address, simply create a forwarding to a non-existing email address (like
email@example.com). Then this email address won’t be caught by the catch-all email address but instead use its forwarding address.
