Confirmed opt-in is vital for anyone doing an email marketing campaign. If you run an emarketing campaign with single opt-in you run the risk of scripts or even Users cruelly using other people's email addresses to sign up to your mailing list, which effectively means you're spamming them. Even though it's unintentionally it is still nonetheless classed as spamming as the email recipient never actually signed up to your mailing list.

In addition, the website Spamza.com promoted itself to do just this: "spam your enemies" by adding their email address to a website form, which Spamza would then subscribe this email address to thousands of e-newsletters.However, Spamza is no longer online (due to their "black hat" techniques) but if you were creating an emarketing campaign using confirmed opt-in and your email newsletter was one that Spamza added addresses to then any of the users from that list would get the confirmed email. Then the email recipient would either mark that as spam or delete it, which would have been the end of it. On the other hand, if you used single opt-in you might have shown up on the URL blacklists (resulting in future broadcasts being blocked at the recipient's mailbox), your mailing list would have been full of irrelevant subscribers leading to lower open rates and fewer conversions, and more significantly your target audience could have deemed you as a spammer. In effective, this demonstrates how important confirmed opt-in is for an emarketing campaign.
