How to Block an Email Sender on iPhone: Easy iOS Steps (2026)

To block an email sender on your iPhone, open the message in the Mail app, tap the sender’s email address at the top, tap View Contact Card, then tap Block this Contact. That adds the address to Apple’s blocked list and every future email from it goes straight to Trash.

There is a faster route if you would rather not open the message. Swipe right to left across it in your inbox list, tap More, then tap Block Sender. Same result, about five seconds.

One thing worth knowing up front: blocking only handles future mail. Anything already sitting in your inbox stays where it is until you delete it yourself. It also covers a lot of ground at once, because the blocked list in Settings is shared with Messages, FaceTime and Phone. If all you want to do is silence marketing email without cutting off that person’s texts and calls, move it to Junk instead.

What You Need

Just your iPhone and the app where the message actually arrives. Apple Mail is built in, and Gmail and Outlook are both free downloads from the App Store if your email lives there.

Here is the part that trips people up: how blocking behaves depends on both the app and the account type. Apple’s Mail app has its own blocked list stored on the device. Gmail and Outlook block at the server, so their filtering happens on every device you sign into, not just your phone.

Menu wording also shifts a little between iOS releases, so if a label does not match what you see on screen, look for the closest equivalent rather than assuming your phone is broken.

Step-by-Step: How to Block an Email Sender on iPhone

Start in the app where the email shows up. The taps differ slightly for each one, but the goal is the same: the address ends up on a block list and future messages from it never reach your inbox.

Block the Sender in Apple Mail

In Apple Mail, tap the message to open it, then tap the sender’s name or email address in the header. A contact card slides up. Tap Block this Contact and the address goes on your blocked list.

You can do the same thing from the inbox list without opening anything. Swipe right to left across the message preview, tap More, then tap Block Sender.

Read the wording carefully before you confirm. Block this Contact blocks that person everywhere on the device, including their calls, texts and FaceTime. If you only want to stop the email, move the message to Junk instead.

Block the Sender in Gmail

In the Gmail app, open the message and tap the sender’s name at the top of the screen. Choose Block sender to stop all mail from that address, or Report spam if it is junk you want Gmail to learn from. Both act immediately.

Report spam is usually the better choice for obvious junk, because it teaches the filter. Block sender is better for a real person or a company whose unsubscribe link is broken.

To undo it, tap your profile picture in the top corner, scroll to and tap the blocked address, then tap Unblock at the bottom of the screen.

Block the Sender in Microsoft Outlook

In Outlook, open the message, tap the three-dot menu at the top, then tap Block sender. Outlook moves the conversation out of your inbox straight away, and it does the same on every device signed into that account.

Outlook also has its own junk controls. Tap Settings, then Junk Email, and you can manage the blocked sender list and decide how aggressively junk mail gets caught.

If the message is obvious phishing, use Report junk rather than Block sender, so the rest of your inbox stays cleaner too.

Block a Sender Without Opening the Email

You never have to read a message to block it. Press and hold the message preview in your inbox list and a menu appears with a Block Sender option, which saves you a tap compared with the swipe route.

You can also block an address that has never sent you anything. Open Settings, tap Mail, scroll down to Blocked, tap Add New, and type the email address in.

If you get a lot of mail from one company through several addresses, searching the mailbox for that sender name and blocking each address one by one gets tedious fast. Rules and filters are better for volume.

Review and Manage Blocked Senders

Open Settings, tap Mail, then scroll to Blocked. This is the one list worth knowing about, because it is also where you unblock people and where you can add an address by hand.

Swipe right to left across a name in that list to unblock it or delete it. Removing a block brings back every future email from that address, so undo one you still need.

Right under Blocked sits Block Sender Options, which decides what happens to blocked mail. With it set to Move to Trash, blocked messages skip the Junk mailbox and land straight in Trash, where they clear out on their own after 30 days. Messages you have already received are untouched by any of this.

The four ways to deal with unwanted mail behave differently enough that picking the wrong one is a common cause of frustration.

	Block Sender	Move to Junk	Mail Filter	Report Spam
What it does	Adds the address to a standing block list	Files one message as junk	Sorts matching mail into a mailbox automatically	Sends the message to junk and trains the filter
Where the message ends up	Trash, or Junk depending on Block Sender Options	Junk mailbox	The mailbox you chose	Junk mailbox
Can you still see it	Yes, in Trash	Yes, in Junk	Yes, in the filtered mailbox	Yes, in Junk
Applies to	Every future message from that address	That message only	Anything matching your criteria	That message, plus similar ones
How to undo	Settings, Mail, Blocked, swipe and unblock	Move it back to the inbox	Tap Toggle Filtering or edit the rule	Not reversible for that message
Best for	A person or company you never want to hear from again	Occasional unwanted mail from a real business	Sorting a busy inbox, or blocking many senders at once	Clear junk and phishing

Common Mistakes

The most common mistake is expecting a block to clean up what already arrived. Blocking is forward-looking only. The ten messages from that sender already in your inbox have to be deleted by hand, one by one or with a multi-select swipe.

Second mistake is blocking in the wrong app. If you read mail in Gmail but do the blocking in Apple Mail, you have blocked nothing. Each app keeps its own list, and each one has to be set up on its own.

Third is tapping the wrong thing. Block Content in Mail is a privacy feature that blocks remote images and trackers. It has nothing to do with senders, which is why people who turned it on still get the email. Similarly, Flag, VIP and Hide My Email all do different jobs.

Fourth is forgetting that the block is standing until you remove it. People block a family member or an old colleague, calm down three weeks later, and assume the problem resolved itself. It did not. Swipe their name off the Blocked list.

Finally, expect one block to cover a whole company. Block an address and the sender simply starts again from a different one, or from a new domain. For persistent senders, mark the messages as junk a few times so the filter picks up the pattern.

A couple of habits keep things tidy. Use unsubscribe first, since it is the cleanest fix, and delete junk rather than blocking it. Reserve blocking for people and companies you have an actual reason to silence.

Frequently Asked Questions

Conclusion

The quickest fix takes about five seconds: swipe right to left across the message in your inbox, tap More, then tap Block Sender. If you would rather see exactly who you are cutting off, open the message and go through View Contact Card to Block this Contact.

Either way, block in the app where the mail actually arrives, and use Junk for the merely annoying stuff so you do not silence someone’s calls by accident. If something keeps getting through, open Settings, Mail, Blocked and check the list first, then delete the messages already sitting in your inbox.
