The fastest way to stop unwanted email
Most email providers let you block a sender with one click. In Gmail, open the email, click the three dots in the top right, and select "Block [sender]". In Outlook, right-click the message and choose "Block". In Apple Mail, click the sender's name and select "Block Contact". Once blocked, emails from that address go straight to spam and you won't see notifications.
Blocking works best when you know exactly who is sending the unwanted mail — a person, a company, or a service you signed up for and now want to stop. It does not stop someone using a different email address, and it does not work against bulk spam from random addresses. For those situations, you need different tools.
Key Takeaways
- Blocking a single sender takes one click in Gmail, Outlook, or Apple Mail, and sends their future emails straight to spam.
- Unsubscribe links at the bottom of marketing emails are usually real and safe to use, even though they look suspicious.
- Spam filters improve when you mark junk mail as spam instead of deleting it, because you teach your email provider what you do not want.
- Never reply to spam, click links in suspicious emails, or confirm your address is real — these actions make you a target for more spam.
- If blocking and filtering do not work, create a new email address for important contacts and use your old one only for shopping and signups.
When to use unsubscribe instead of blocking
Marketing emails from real companies — newsletters, sale announcements, shipping updates — almost always have an unsubscribe link at the very bottom. Clicking it removes you from that sender's mailing list. This is safer and more effective than blocking, because it tells the company to stop sending to you, rather than just hiding their emails from your view.
Unsubscribe links are required by law in most countries, including the United States under the CAN-SPAM Act. Companies that ignore unsubscribe requests face fines, so most legitimate businesses process them. The link usually takes you to a page where you confirm your email address and the company removes it from their list within a few days.
If you unsubscribe and the emails keep coming after two weeks, then you can block the sender. But start with unsubscribe, because it actually stops the source rather than just filtering what reaches you.
How to train your spam filter to catch more junk
Every time you mark an email as spam instead of deleting it, your email provider learns what you do not want. Over time, your filter gets better at catching similar messages before they reach your inbox. Gmail, Outlook, and Apple Mail all use this feedback to improve.
Mark an email as spam by clicking the spam or trash icon in your email client — usually a triangle or exclamation mark. Do this for unwanted newsletters you have not unsubscribed from, obvious scams, and any message that looks like it is trying to trick you. The more you mark, the smarter your filter becomes.
Do not rely on the filter alone for security. Spam filters catch most junk, but some scams and phishing emails still get through. That is why the habit of spotting red flags — urgent language, requests for passwords, suspicious links — matters more than the filter itself.
What not to do when you get spam
Never reply to spam, even to ask them to stop. A reply confirms your email address is real and monitored, which makes you more valuable to spammers. They sell active addresses to other spammers, and you end up on more lists.
Do not click links in emails from senders you do not recognize, even if the email looks official. Scammers use fake logos and urgent language to trick you into clicking. If you think an email might be real — a bank warning, a package delivery — go directly to the company's website by typing the address yourself, rather than clicking the link in the email.
Do not confirm your address by replying with "remove me" or "stop sending". Again, this tells spammers the address works. If an email has an unsubscribe link, use that. If it does not, block the sender or mark it as spam.
Using filters and folders to organize what gets through
Even after blocking and unsubscribing, some unwanted mail will still arrive. Email filters let you automatically sort or hide messages based on who sent them or what words they contain. In Gmail, click the three dots on an email and select "Create filter". In Outlook, right-click and choose "Create rule". In Apple Mail, go to Mail menu → Preferences → Rules.
You can set a filter to automatically send certain emails to a folder, mark them as read, or skip your inbox entirely. For example, you might filter all emails from a particular domain to a "Low Priority" folder, or send receipts from online shopping straight to an archive. This keeps your inbox focused on what matters without deleting anything.
Filters work best when you are specific. A filter for "all emails from notifications@company.com" is more useful than a filter for "all emails with the word 'update'", which might catch important messages by mistake.
When to create a new email address
If your current email address receives so much spam that blocking and filtering no longer work, the simplest solution is to start fresh. Create a new email address and give it only to people and services you trust — your bank, your employer, close friends and family. Use your old address only for shopping, signups, and services where you expect marketing mail.
This takes time to set up, but it works because your new address has no spam history. You can keep your old address active to receive mail from old contacts, but you do not have to check it often. Over months or years, your new address will accumulate some unwanted mail, but you will have bought yourself time and a cleaner inbox.
Before you abandon an old address entirely, update your important accounts — banking, email recovery, work — to use the new one. Check your old inbox occasionally for mail from people who have not switched over yet.
Recognizing when spam is actually a scam
Most spam is just marketing or sales pitches. But some emails are phishing attempts designed to steal your password, credit card number, or personal information. The difference matters, because blocking a phishing email is not enough — you also need to protect yourself from the trick itself.
Red flags for scams include: urgent language ("act now", "confirm when ready"), requests for passwords or financial information, links that do not match the sender's real website, and poor spelling or grammar. If an email claims to be from your bank but asks you to "verify your account", it is almost certainly fake. Real banks never ask for passwords by email.
If you receive a phishing email, block it, mark it as spam, and do not click anything in it. If the email claims to be from a company you use, go to that company's website directly and log in to check your account. Do not use any link from the suspicious email.
Frequently Asked Questions
Can someone send me email if I block them?
No. Once you block a sender, their emails go straight to your spam folder and you receive no notification. They cannot see that you blocked them. If they switch to a different email address, those emails will come through normally unless you block that address too.
Is it safe to click unsubscribe links?
Yes, unsubscribe links from legitimate companies are safe. They are required by law and do exactly what they say — remove you from the mailing list. The risk is only if the email itself is a phishing scam pretending to be from a real company. If you are unsure whether an email is real, go to the company's website directly instead of clicking the link.
What is the difference between blocking and marking as spam?
Blocking hides future emails from a sender in your spam folder. Marking as spam does the same thing but also teaches your filter that similar emails are unwanted. Use marking as spam for bulk mail and obvious junk, and blocking for specific senders you want to stop completely.
Will unsubscribing remove my address from all spam lists?
Unsubscribe only removes you from that one company's mailing list. Your address may already be on other spam lists, sold by data brokers, or harvested from public websites. Unsubscribe from legitimate marketing, but expect spam from other sources to continue.
What should I do if I accidentally clicked a suspicious link?
Do not panic. Clicking a link alone does not infect your computer or steal information. If the link took you to a page asking for your password or credit card, close the page when ready and do not enter anything. If you are worried, change your password for that account from a different device. If the email claimed to be from your bank, call the bank directly using the number on your card or statement.
