Very little.
Think it through.
At some point a bad person will see the email and add it to a spamming list.
Somewhere else a contacts list on a PC will be hacked and it has your email.
If it's out there, it will be recorded.
So instead make sure you have a good spamming email application.
I have a specific email address I use for 'iffy' contacts.
To date, it has never returned a SPAM email.
Either my service provider has the best product going or nobody likes me enough.
