The three ways to stop an email sender on iPhone

iPhone's Mail app gives you three separate tools to stop unwanted emails, and which one you use depends on what the sender is doing. You can block a sender so their emails never reach your inbox, unsubscribe from a mailing list if there's an unsubscribe link, or report as junk to train the system to catch similar messages. Most people need only the first one — blocking — but knowing all three means you won't waste time on a sender you can't actually block.

The difference matters because blocking works on any sender, but unsubscribing only works if the sender included an unsubscribe link (required by law for marketing emails, but not for personal harassment). Reporting as junk helps future emails but doesn't stop the current sender when ready. You can use all three on the same sender if you want to be thorough.

Key Takeaways

  • Open any email from the sender, tap the flag icon, then tap Block Contact to prevent all their future emails from reaching your inbox.
  • If the email is a marketing message, look for an Unsubscribe link at the bottom and tap it to remove yourself from that mailing list.
  • Tap Report Junk to flag a message as spam, which trains Mail to catch similar emails in the future but does not block the sender.
  • Blocked senders' emails go to a separate folder you can check later if you change your mind, rather than being deleted.
  • If you block someone in Mail, they are not blocked in Messages, FaceTime, or other iPhone apps — you must block them separately in each one.

How to block a sender in Mail

Open the email from the sender you want to block. Tap the flag icon in the top right corner of the email — it looks like a small flag. A menu will appear with several options. Tap Block Contact.

That sender's emails will now skip your inbox and go directly to a folder called VIP or Blocked, depending on your iPhone settings. You can check that folder later if you want to see what they sent, but you won't be bothered by notifications. If you change your mind, you can unblock them the same way: open any of their emails, tap the flag, and select Unblock Contact.

How to unsubscribe from a mailing list

Marketing emails — newsletters, promotional offers, account notifications from services — are required by law to include an unsubscribe link. Scroll to the very bottom of the email. You will usually see small text that says "Unsubscribe" or "Manage Preferences" or "Update Your Settings." Tap that link.

Your browser will open and take you to a page where you can confirm you want to leave the mailing list. Some services let you choose which types of emails to receive instead of unsubscribing completely. After you confirm, you should stop receiving emails from that sender within a few days. This method is faster than blocking if the sender is legitimate but you straightforward don't want their messages anymore.

How to report an email as junk

Open the email and tap the flag icon in the top right. Select Report Junk. The email will be moved to your Junk folder, and Mail will learn to catch similar messages from that sender in the future.

Reporting as junk is useful when you're not sure if you want to block the sender permanently, or when you want to help train your Mail system to recognize a pattern of spam. Unlike blocking, it does not prevent future emails from arriving — they will just go to Junk instead of your inbox. If you report the same sender multiple times, Mail may eventually block them automatically, but blocking them directly is faster.

What happens to blocked emails

When you block a sender, their emails do not disappear — they go to a separate folder. On most iPhones, this folder is called VIP or Blocked, depending on your Mail settings. You can still read them if you want to check whether you made a mistake, or if you need to refer back to something they sent.

To see your blocked emails, open Mail and look at the folder list on the left side of the screen. Scroll down until you see the Blocked folder. Tap it to view all emails from senders you have blocked. If you want to unblock someone, open one of their emails and tap the flag icon, then select Unblock Contact.

Blocking does not work across all iPhone apps

Blocking someone in Mail only affects the Mail app. If you block a sender's email address, they can still text you through Messages, call you, or reach you through FaceTime. You must block them separately in each app.

To block someone in Messages, open a conversation with them, tap their name at the top, scroll down, and tap Block This Caller. To block in FaceTime, open the app, find their name in your recent calls, swipe left on it, and tap Block. These actions are separate from Mail blocking, so do not assume blocking an email address protects you across your entire phone.

When blocking is not enough

If someone is sending you threatening, harassing, or abusive emails, blocking them in Mail is a good first step, but it may not be enough. Save the emails as evidence before you block them — take screenshots or forward them to yourself in a separate folder. If the harassment continues from new email addresses, or if the content is threatening, contact local police or your email provider's abuse team.

Most email providers, including iCloud Mail, have abuse reporting tools. You can report a sender directly to Apple by forwarding the email to reportphishing@apple.com. Keep records of dates, times, and the content of the messages. If the harassment is severe or involves threats, do not rely on blocking alone — involve law enforcement.

Frequently Asked Questions

Can I block multiple senders at once?

No, you must block each sender individually by opening their email and tapping the flag icon. If you receive spam from many different addresses, blocking them one by one is tedious, but reporting them as junk and using Mail's spam filters together can reduce what reaches your inbox. Consider creating a rule in Mail settings to automatically sort emails from certain domains into Junk.

What if the sender is using a different email address each time?

If someone is harassing you from multiple addresses, blocking individual senders will not stop them. Instead, report the emails to Apple at reportphishing@apple.com and save screenshots of the messages. If the harassment is severe, contact local police. You can also ask your email provider about blocking entire domains or setting up filters based on keywords in the subject line.

Will the sender know I blocked them?

No, the sender will not receive a notification that you blocked them. Their emails will straightforward fail to reach your inbox, and they may assume you are not reading their messages. If they contact you through another method asking why you are not responding, that is when they will know something changed.

Can I unblock someone after blocking them?

Yes, you can unblock anyone at any time. Open one of their emails from your Blocked folder, tap the flag icon, and select Unblock Contact. After you unblock them, their future emails will return to your inbox normally, and you will see notifications again.

Does blocking delete the emails I already received?

No, blocking only affects future emails. Any messages you already received from that sender stay in your mailbox or Blocked folder. If you want to delete them, you must do that manually by selecting the emails and tapping Delete.
