The fastest way to stop unwanted emails
The simplest method is to unsubscribe using the link at the bottom of the email itself. Nearly every legitimate marketing email contains an unsubscribe link in small text at the footer — click it, confirm your request on the page that opens, and you will stop receiving that sender's emails within a few days. This works because the sender is legally required to honor it.
If there is no unsubscribe link, or if clicking it does not work, move the email to spam or junk instead. Most email providers (Gmail, Outlook, Yahoo) learn from this action and automatically send future emails from that sender to your spam folder. After a few emails land there, you can delete them without opening them.
For emails that pretend to be from a company you actually use — your bank, a retailer, a service you pay for — do not click unsubscribe or any link in the email. These are often phishing attempts designed to confirm your email address is active. Instead, go directly to that company's website, log into your account, and look for email preferences or notification settings there.
Key Takeaways
- Unsubscribe links at the bottom of emails are the fastest way to stop unwanted messages, and senders are required by law to process them within days.
- Moving emails to spam or junk trains your email provider to filter future messages from that sender automatically.
- Never click links in emails claiming to be from your bank or other services you use — go to their website directly instead to change your settings.
- Creating a separate email address for online shopping and signups keeps unwanted marketing away from your main inbox.
- Email filters and rules let you automatically sort or delete messages from specific senders without reading them.
Using your email provider's built-in filters
Gmail, Outlook, and Yahoo all let you create rules that automatically handle emails from certain senders or with certain words in the subject line. In Gmail, open an unwanted email, click the three-dot menu at the top right, and select "Block [sender]" — all future emails from that address go straight to spam. You can also click "Filter messages like these" to catch emails with similar characteristics.
Outlook works similarly: right-click the email, choose "Junk," then "Block Sender." Yahoo has a "Block" button in the toolbar when you open an email. These actions are permanent unless you undo them later, so use them for senders you never want to hear from again.
If you want more control, most providers let you create custom rules. In Gmail, go to Settings > Filters and Blocked Addresses > Create a new filter. You can specify a sender, subject line keywords, or words that appear in the email body, then choose what happens to matching emails — delete them, send them to a folder, or mark them as read automatically.
Protecting your email address from being sold
Unwanted emails often arrive because your address was sold to marketers or harvested from a public website. You cannot undo this, but you can slow it down. When you sign up for online services, look for checkboxes that say "Send me promotional emails" or "Share my information with partners" — leave these unchecked. Many sites check them by default, so you have to actively uncheck them.
If you shop online frequently, create a separate email address just for retail and signup forms. Use your main email only for people and services you trust. This keeps your primary inbox cleaner and makes it easier to delete the secondary address later if it becomes overwhelmed.
You can also register your email address with the National Do Not Call Registry's email equivalent, though it is less effective than the phone registry. Visit donotcall.gov and look for the email preference service option. This tells some marketers not to contact you, but it does not stop all unwanted mail.
Dealing with emails that look like they are from companies you know
Phishing emails pretend to be from your bank, PayPal, Amazon, or another service you use, often claiming there is a problem with your account or a package waiting. They include a link that looks legitimate but actually goes to a fake website designed to steal your password or payment information. Never click these links.
If you are unsure whether an email is real, open a new browser tab and go directly to the company's website by typing the address yourself. Log into your account and check your messages or notifications there. Real companies will never ask you to click a link in an email to verify your identity or update payment information.
Report these emails as phishing to your email provider. In Gmail, click the three-dot menu and select "Report phishing." In Outlook, click the "Junk" button and choose "Phishing." This helps protect other users by training the email system to catch similar messages.
When to use a disposable email address
Some websites offer temporary email addresses that expire after a set time — services like Temp Mail, 10 Minute Mail, or Guerrillamail generate a random address you can use for one-time signups. The email address deletes itself after 10 minutes to an hour, so any unwanted messages disappear automatically.
This approach works well for free trials, one-time downloads, or websites you do not trust. However, you will not receive password reset emails or account notifications once the temporary address expires, so only use this method when you do not plan to return to the site.
A more practical middle ground is to use your email provider's alias or forwarding feature. Gmail lets you add a plus sign and any word to your address — for example, if your email is john@gmail.com, you can sign up for a shopping site using john+shopping@gmail.com. All emails go to your main inbox, but you can filter them separately or see which company sold your address if unwanted mail arrives at that alias.
What to do if your email address is compromised
If you suddenly receive a flood of unwanted emails, or if you get messages saying your password was reset when you did not reset it, your email address may have been exposed in a data breach. Check haveibeenpwned.com and enter your email address — the site will tell you if your address appeared in any known breaches.
If your address was compromised, change your email password when ready, then change passwords for any important accounts (banking, email, social media) that use that email address. Enable two-factor authentication on your email account if your provider offers it — this adds a second verification step that makes it harder for someone else to access your account even if they have your password.
You may also want to consider creating a new email address for sensitive accounts going forward. This is time-consuming but provides a fresh start if your old address has been widely distributed to spammers.
Frequently Asked Questions
Is it safe to click unsubscribe on emails I did not sign up for?
Unsubscribe links on legitimate marketing emails are safe — the sender is required by law to honor them. However, if the email looks suspicious or claims to be from a company you do not use, do not click the unsubscribe link. Move it to spam instead. Clicking unsubscribe on a phishing email confirms your address is active and may lead to more unwanted mail.
Will marking emails as spam stop them completely?
Marking emails as spam trains your email provider to filter future messages from that sender, but it does not contact the sender to remove you from their list. For legitimate marketing emails, unsubscribe is more effective. For spam and phishing, marking as spam is the right choice since there is no real unsubscribe to honor.
Can I report unwanted emails to the police or FTC?
The Federal Trade Commission accepts reports of unwanted emails at spam@uce.gov. However, they do not investigate individual complaints — they use patterns from many reports to identify large-scale spam operations. For phishing emails that target your bank or payment account, report them to that company's fraud department directly.
Why do I still get emails after unsubscribing?
Unsubscribe requests take a few days to process, so you may receive one or two more emails before they stop. If emails continue after a week, the sender may not be honoring the request. Move those emails to spam instead, or contact the company directly through their website to complain.
Does changing my email address stop all unwanted mail?
Creating a new email address gives you a fresh start, but only if you keep it private and use it carefully. If you sign up for many websites or share it publicly, it will eventually accumulate unwanted mail again. The key is being selective about where you give out your new address.
