Unobfuscate a Spammy Email
See more Email Object Examples
Demonstrates the Chilkat Email.UnSpamify method, which unobfuscates an email by undoing common spammer tricks — it removes comments from HTML bodies and unobfuscates hyperlinked URLs. This example cleans an HTML body whose link was broken up by an inserted comment.
Background: Spammers deliberately scramble HTML to slip past filters — inserting empty comments in the middle of words or URLs (
exa<!--x-->mple.com), or otherwise obfuscating links — so the message renders normally to a human but confuses naive keyword matching. UnSpamify reverses those tricks, producing a normalized body that is easier to analyze, classify, or scan for the real destination of its links.Chilkat Delphi ActiveX Downloads
