Whatever is claimed inside of such messages, it is most likely a scam simply designed to trick users into exposing their personal information to cybercriminals. The entered passwords and account names can therefore be used not only for stealing the e-mail but also for accessing accounts on other services registered with the same credentials. Note that there is an abundance of such messages with similar content getting sent to users each day. Although their content may vary from person to person, the essence remains the same – to fool users into performing scam-driven steps. If you became a victim of this or a similar scam and suspect that your account might be in danger, it is therefore advised to change your passwords immediately and take additional security measures like setting up two-factor authentication if you have not done it yet.

If an e-mail message has not been put to the “spam” or “junk” folder itself, then users can do it themselves in just a couple of steps. Marking e-mail as spam will let your e-mail service know how to treat the unwanted sender next time. All further messages received from the spam-marked address will be located in the appropriate folder already without your help. Here is how:

Gmail:

3. Unsubscribe from e-mail campaigns

Many websites offer users to enter their e-mail address in exchange for exclusive content notifications, and tons of other marketing stuff. Over some time, regular users can subscribe to multiple resources that bombard your inbox and spam folder with continuous messages. This can be stopped by unsubscribing to them. Many messages, if opened, have a small gray hyperlink or button “Unsubscribe”. Clicking on it should unsubscribe you from letters you have been receiving for some time. Note that some intentionally malicious letters may use fake “Unsubscribe” buttons to deceive users into downloading malware or visiting suspicious pages. Therefore, remember to always stay on alert!

You can also do the following to unsubscribe to multiple newsletters in Gmail at once:

  1. Open your Gmail and type Unsubscribe into the search box on top.
  2. Then, click on the Show search options icon on the right end of the search box.
  3. Click on Create filter and select checkboxes next to Delete it and Apply filter to matching conversations.
  4. After selecting, finish by clicking on Create filter.

This will lead to all previously subscribed messages evaporating from your flood list in seconds. No more letters of such will appear in your Inbox or other folders again.

4. Change your e-mail address and forward it

It is sometimes hard to get rid of all spam in case of an e-mail breach. Receiving unreasonably high numbers of spam could mean your e-mail was leaked to large masses of spamming campaigns grateful to use it. Victims of this can quite easily avoid it by creating a new e-mail address and forwarding incoming e-mails from their old address. Don’t worry, this will not redirect abnormal streams of spam to this new address, but only normal messages you received on your behalf. It is also worth notifying people you had close contact with that you changed your e-mail address, so they do not get scared after receiving a message from an unknown address.

  1. First, you should begin with creating a new account for the e-mail service you use (Gmail, Yahoo, Outlook, or Apple Mail).
  2. Then, log back into your old account, go to Settings and Add a forwarding address. In Gmail, these settings can be found in the Forwarding POP/IMAP tab. Something similar should be in other services as well.
  3. Enter the newly created e-mail address and click Next > Proceed > OK.
  4. You will then receive a verification message in that newly created address. Make sure you click on it.

If you also want to forward a copy of already existing e-mails, do the following:

  1. Go back to the settings page for the Gmail account you want to forward messages from, and refresh your browser.
  2. Navigate to Forwarding and POP/IMAP and select Forward a copy of incoming mail to.
  3. Choose what you want to happen with the Gmail copy of your emails. It is recommended to choose Keep Gmail’s copy in the Inbox. Click Save changes at the end.

All done and dusted! Now, all new messages tied to the previous e-mail will be sent to your new address.

Final tips

There is always a good practice to have personal and business e-mail accounts separately. If you are active on forums, Q&A sites, participate in link building you will probably need another account for that. Major e-mail services and applications like Gmail, Yahoo! Mail, Apple Mail and Outlook already have strong built-in anti-spam technologies, however, we recommend special software like MailWasher Pro to fight spam campaigns like “Last Warning: Upgrade Your Email To Avoid Shutting Down”.
