That's what an email obfuscator does. It makes it difficult for people to get your email address and send you junk emails. On the World Wide Web, there are programs known as "spambots". These programs, also called spiders, crawl around the web searching for email addresses on web pages. When the spiders find web pages with an email address, they collect it and attempt to sell or circulate it to unscrupulous people who want to send "spam", or unsolicited commercial email.

What if you want to put an email link on your website, but you don't want to risk exposing yourself to this sort of email abuse? Simple. Make sure that your email address link works for humans but not for spambots!
