How to Stop Spam

This wikiHow teaches you how to identify, prevent, and block email spam. While blocking spam in your inbox won't always prevent future spam from arriving, it will help your email provider determine which messages constitute spam. You can block spam messages in desktop and mobile versions of Gmail, Outlook, Yahoo, and Apple Mail.

Preventing Spam

  1. Image titled Stop Spam Step 1
    1
    Only use your personal and business emails for personal or business uses. Don't use your personal or business email to sign up for contests, online services, apps, or mailing lists. Many spammers monitor these mailing lists and look for email addresses to spam. You can easily create a new Gmail, Outlook or Yahoo account for free. It's a good idea to have a separate email account that you use to sign up for frivolous services and mailing lists.
  2. Image titled Stop Spam Step 2

    Check who emails are from. Most of the time, spam comes from an unrecognized sender, often with odd email addresses. That doesn’t mean all unrecognized email is spam—legitimate newsletters, website administration emails (password resets, authentication requests, etc.), and more may come from addresses you don’t recognize—but spam emails usually have multiple numbers, dashes, and/or odd letter combinations in them.[1]
    • Only open emails and links in emails if you trust the sender. You should either know the sender, be expecting an email from them, or have a reasonable reason for why the other person would send you an email randomly.

    Avoid clicking on links in emails. The goal of most spam emails is to get you to click on a link, so only click links in emails from people who you know and trust.[2]
    • If you're unsure of a link in an email from a friend, consider calling them and asking about the link. It is possible their contacts list was compromised by spam. If you receive a suspicious email from a company, bank, or organization that you have an account with, you can usually find out if there is a problem with your account by opening a new browser window and logging in to your account from their website.
  4. Image titled Stop Spam Step 4
    4
    Check the email's spelling. Spam often contains misspellings and oddly-worded sentences. This can include bizarre capitalization and weird punctuation, or awkward formatting such as bolding, italics, and randomly colored text.
  5. Image titled Stop Spam Step 5
    5
    Read the message. Anything that claims you won a contest you never entered, offers you access to unclaimed money or promises free electronics, jewelry, or anything 100% free is never legitimate. Any message that asks for your password is never real. All legitimate websites have automated password reset programs. Requests from strangers should always be ignored.[3]
    • Many email services have a preview window that will allow you to read the beginning of an email message without opening it. This will help you avoid downloading any malicious attachments within the email.
  6. Image titled Stop Spam Step 6
    6
    Don't post your email publicly or online. Scripts created to comb through websites for email addresses can quickly gather thousands of emails at a time from websites where the email addresses are made public. Avoid entering your email address to sign up for things like coupons. Never type out your email address in a comment or post online or make your email address publicly available on Facebook or other social media services. Always be careful who you give your email to. If you need an email address to sign up for frivolous services, you can create one for free using Gmail, Outlook, Yahoo.[4]
  7. Image titled Stop Spam Step 7
    7
    Make your email address unscannable. If you must provide your email address in a public context, try writing it out in creative ways (e.g., "name [at] yahoo [dot] com" instead of "name@yahoo.com"). This will prevent would-be spammers from pulling your email address with an automated program.
  8. Image titled Stop Spam Step 8
    8
    Don’t make your username the same as your email address. Usernames are almost always public. This makes email discovery a simple matter of figuring out the correct service to add at the end.
    • Services such as Yahoo! Chat make this even easier, since chances are everyone using it has a @yahoo.com email address.
  9. Image titled Stop Spam Step 9
    9
    Never respond to spam. Replying or clicking the “Unsubscribe” link confirms that your email address is valid and active. This will generate more spam. It is best to report and delete the spam using the steps in the following sections.[5]

    While you are able to set up filters and spam blockers, you might not be able to prevent every spam email from coming to your inbox. The best thing to do is just be able to recognize when an email is spam and to not respond to it.
  • Question
    What is the evidence that unsubscribing increases spam?
    Community Answer
    Community Answer
    If you click the unsubscribe button, that confirms that your email is a valid email. Ignore it and they will eventually assume it is abandoned or fake.
  • Question
    How do I stop spammers from using my email address as the permitted sender?
    Community Answer
    Community Answer
    Some email services (such as Gmail) provide double authentication to log in to the account. Usually a mobile phone is needed. Make sure to enable this, and check to see whether the junk mail is still sent from there. If it is, then there is possibly a virus installed on your phone which is used to catch data on it. Otherwise it may be one of your friends having a laugh.

Warnings

  • Reporting an email as spam will usually mark future emails from the same person or service by default, but you may have to mark the same sender or service as spam a few times before you no longer see their messages in your inbox.
