There are emails from which you should certainly unsubscribe when you no longer want them. However there are emails that you absolutely should never unsubscribe from. I'll review the differences.//
I am receiving a lot of unwanted e-mails from diet pills to pet supplies and I don’t want to keep deleting 100 e-mails every time I check my mail. I hate going into each e-mail one-by-one to unsubscribe and I don’t know how safe it is for me to open those e-mails in the first place. I was wondering is there an easy free way to unsubscribe without needing to open the e-mail.
I know that this is confusing, but it’s important to realize that there are emails that you can and should unsubscribe from, and emails that you absolutely should never, ever “unsubscribe” from.
I’ll explain why that is, and what the relatively simple rules turn out to be.
Don’t unsubscribe from spam
What you are getting is most likely and simply spam. Spam is sent to random email addresses. You haven’t been “subscribed” at all. You’re just getting it like many people do: at random.
This is important: since you haven’t been subscribed, there’s nothing to unsubscribe from, even if there’s an “unsubscribe” link. Clicking on that unsubscribe link will not help. In fact, it’ll likely make matters worse.
You might be asking “if I’m not subscribed, then why is there an unsubscribe link?”.
Simple: spammers lie.
Like I said, spam is sent out at random and to email addresses that are both legitimate and not. The act of clicking that “unsubscribe” link actually confirms to the spammer that your email address is a real, valid email address with a real person reading it.
From the spammers perspective it allows them to say the equivalent of “we got us a live one!”
And once they know that the email address is legitimate, they’ll start sending you MORE, not less, spam.
Thus this rule of thumb: “unsubscribing” from spam will only get you more spam.
Instead, click on the “This is Spam” button in your email program or interface to both get the email out of your inbox and train that service as to what spam looks like. That helps the service automatically identify spam for you in the future, and is by far the safest, most effective approach to dealing with spam using tools you probably already have at your disposal.
Do unsubscribe from things you asked for
As a newsletter publisher myself, I do want to emphasize that when you’re ready to stop a legitimate mailing, a mailing that you subscribed to, you do want to use the unsubscribe link.
Do not click “this is spam” for legitimate email. When you click on “this is spam” for legitimate email that may actually cause other people – people who actually want it – to stop getting it.
