How to Block Unwanted Emails on iPhone (and Where Blocking Stops)

To block an email sender on iPhone, open the message, tap the sender’s address, tap View Contact Card, then tap Block this Contact. Future mail from that address is handled by Mail on your Apple devices, not stopped at your mailbox. To stop it arriving at all, add a block or filter in Gmail, Outlook or iCloud.

Below: block in Mail, block in the Gmail app, stop it at the server, then the limits worth knowing (unsubscribe, Junk, Categories and Hide My Email). If you block a sender and mail still turns up, see why blocked senders still arrive.

How to Block a Sender in Mail on iPhone#

1. 1

   Open a message from the sender

   In the Mail app, tap the message so it opens in full.

2. 2

   Tap the sender, then View Contact Card

   Tap their email address at the top of the message, then tap View Contact Card. This is the route in Apple’s current iPhone guide.

3. 3

   Tap Block this Contact

   Confirm if iOS asks you to. From now on Mail treats that address as blocked, and Apple says blocked email goes to the Trash folder.

4. 4

   Check Blocked Sender Options

   In recent versions it sits at Settings > Apps > Mail > Blocked Sender Options (older versions: Settings > Mail). Pick Move to Trash if you want blocked mail out of sight. The exact label and location can differ by iOS version.

5. 5

   Add, review or undo blocks

   Go to Settings > Privacy & Security > Blocked Contacts (iOS 26 wording). Tap Add Blocked Contact to type an address without opening a message, or tap Edit to remove one.

Blocked Sender Options: What Each Setting Does#

Blocking a contact and choosing what Mail does with their messages are two separate steps. If blocked mail still shows in your inbox, this setting is the first thing to check. The Apple Mail guide for Mac lists the same three choices, labelled Bin instead of Trash in some regions.

How to Block a Sender in the Gmail App on iPhone#

The Gmail app keeps its own block list on your Google account, separate from Apple Mail. Per Google’s help page, after you block a sender all future emails from them go to Spam.

1. 1

   Open the Gmail app and the message

   Open the message from the sender you want to block.

2. 2

   Tap More, then Block

   At the top right, next to Reply, tap More, then tap Block followed by the sender’s name. Tap Unblock in the same place to undo it.

How to Permanently Block Emails on iPhone (Stop Them at the Server)#

Mail’s block is a display rule on your Apple devices. A filter at your provider runs on the server as each message arrives, on every device and in every app. For senders you want gone for good, combine the two: Block this Contact with Move to Trash on the phone, plus a provider rule.

That is also how you block a whole domain. Apple’s steps cover adding a contact or address and do not document domain-level blocking in Mail, so use your provider for that. In Gmail, build a filter on the domain. See Gmail filters for the walk-through. Yahoo accounts are covered in stopping Yahoo spam on iPhone.

Can You Block Emails in Bulk on iPhone?#

Not in Mail. Apple’s Blocked Contacts screen adds one contact at a time, and Apple’s documentation describes no bulk block or import option. For a long list of senders you have three routes: type the addresses in one by one, create a single filter at your provider that catches a domain or a pattern, or use a dedicated blocker app (see best spam blocker apps for iPhone). If the problem is newsletters rather than spam, unsubscribing clears more mail faster than blocking.

What Mail on iPhone Cannot Do#

Mail on iPhone is a viewer for accounts held elsewhere. Gmail, Outlook or iCloud decide what lands in your mailbox, and Mail decides how it looks on screen. That is why blocking changes what you see rather than what is delivered.

• There is no rules engine in the iPhone app. The Filter button in the mailbox list only changes which messages are shown. It does not move, label or delete anything.
• A block does not carry over to the Gmail or Outlook apps. Each keeps its own block list.
• The unsubscribe banner appears only when the sender includes the standard list-unsubscribe information. No header, no banner.
• Categories tidy the inbox but do not stop delivery. Promotions you ignore still arrive and take up space.

Unsubscribe, Junk and Categories#

When a message carries unsubscribe information, Mail shows an Unsubscribe banner at the top. Tap it and Mail sends the request for you. Senders can take a while to act on it, and scammers ignore it, so use it for newsletters you signed up to, not for spam.

Mark as Junk files the message in that account’s Junk or Spam folder. It does not block the sender, and Apple does not document how much weight your provider gives the signal. For Gmail accounts, Report spam inside Gmail is the clearer signal.

On iOS 18.2 and later, Mail sorts incoming mail into Primary, Transactions, Updates and Promotions (not available in every country or region). To turn categories off, open an inbox, tap the more button and tap Show Categories. To move a sender into another category, tap Categorize Sender in the same menu.

Hide My Email: Containment for Future Signups#

iCloud+ subscribers can create Hide My Email addresses for new signups. Each one forwards to a personal address on your Apple Account. If a service starts sending spam, go to Settings > your name > iCloud > Hide My Email, select the address and tap Deactivate Email Address. Mail to it stops forwarding, and you can reactivate it later.

It only protects future signups. An address a data broker or marketing list already holds stays in circulation. If you use Gmail, plus-addressing ([email protected]) at least tells you who leaked it, and you can filter on the tag.

A Faster Way to Deal With Volume#

Blocking works for the odd sender. When unwanted mail arrives faster than you can block it, the problem is volume, not any single address.

AI Emaily is our email client, so weigh this accordingly. It connects to Gmail, Outlook, iCloud or IMAP accounts and applies its cold-email filter, rules and labels at the account level, so they follow you across the web app, desktop apps and the iOS app. In Copilot mode anything it drafts waits for your approval before it sends. It comes with a 7-day free trial; see pricing for current plans. If a provider filter already handles your volume, you may not need it.
