Email - tips for domain owners

[Mike30]

Heve you ever been bombarded with emails and offers and
you really don't know from where they got your email?

Here is a tip:

I use a domain just for that

1- I go to the email control panner and I put all unrouted emails to
be forwared to one email.

2- Every time you sign-up on any website use the name of your
that site as your email.
Example: If you sign-up at: example.com then use this email: example@yourdomain.com

So every time you receive an email you will know where you use that email.

please put here any comment or any other tips you use.

Thanks.
