Try to avoid advertising your address on any websites and forums where you do not have complete control of your own privacy. If for some reason you would need to include an email address, try to obscure it for spam bots.
Make sure you unsubscribe: A good email marketing company will ensure that their users include unsubscribe options in all email headers and /or footers. With that said, many people believe that clicking an unsubscribe link actually confirms to a spammer that the user exists/actively reads their mail.
Create separate addresses for core communications and disposable ones for general use: It would be a good idea to have one email account for your banking, mortgage, e-statements and so on – all of your essential life necessities.
Mark unwanted mail as spam: Email services such as Hotmail and Gmail will create a filter to automatically spot all future mail from that source as junk and it will submit a complaint against the network that sent the mail to reputation monitoring services
Do not submit your email address to websites or companies that you are unfamiliar with and / or have no reason to trust. You wouldn’t think of giving your mobile number to strangers, after all – the same justification applies to your email address.
A disposable address is an inbox that you will typically use when a store asks you to fill out your details for purposes such as future specials, club membership or anything that’s not important to you or that you want to specifically keep separate.
