Blacklisting Certain Ips

Another commonly used spam filtering technique is blacklisting certain IP addresses that are known to be used by spammers. This way, you can prevent spam emails from those IPs.

Avoid Posting Your Email ID Publicly in the Internet

Avoid posting your real email address on the public lists and forms if you don’t have to. This way you can prevent spammers from accessing your email and purchasing it from other spammers (email harvesting).

If you want to post your real email address on a website or something similar, use extra spaces or preferably replace the @ symbol in your email with (at). Avoid posting your entire email ID in the form that it’s used to send the message. This will reduce the chance of spambots finding your real email ID online.

Use Contact Forms

If you running a business, you can use contact forms on your website instead of using your real email ID. This may be your best option for reducing the amount of spam you get. Users won’t see your email ID and instead fill out the form in the web browser which will send that info to your email address.
