How to Block Addresses in Gmail: A Complete Guide
Unwanted emails are more than an annoyance — they clutter your inbox, waste your time, and can sometimes carry phishing attempts or spam. Gmail gives you several ways to block senders, but the method that works best depends on your device, how you access Gmail, and what you actually want to happen to those blocked messages.
What "Blocking" Actually Does in Gmail
When you block a sender in Gmail, you're telling Google to automatically send any future emails from that address directly to your Spam folder — not your inbox. The emails still arrive at your account; they just get rerouted silently. Gmail doesn't notify the sender that they've been blocked, so there's no awkward back-and-forth about it.
This is an important distinction: blocking is not the same as deleting. Blocked emails accumulate in Spam and are automatically purged after 30 days unless you manually delete them sooner.
How to Block an Email Address in Gmail on Desktop
The most straightforward method works through Gmail's web interface in any browser.
- Open the email from the sender you want to block.
- Click the three-dot menu (⋮) in the top-right corner of the email — not the main Gmail menu, but the one inside the message itself.
- Select "Block [sender name]" from the dropdown.
- A confirmation prompt will appear. Click Block to confirm.
That's it. From that point on, emails from that address go straight to Spam. 🚫
How to Block a Sender in the Gmail Mobile App
The process on Android and iOS is slightly different but equally simple.
- Open the Gmail app and tap the email from the sender you want to block.
- Tap the three-dot menu in the top-right corner of the message.
- Select "Block [sender name]".
- Confirm when prompted.
The block applies account-wide — so if you block someone on mobile, they're blocked on desktop too, since it's tied to your Google account, not your device.
How to Unblock a Sender
Blocking is reversible. If you change your mind:
- Go to Gmail Settings (the gear icon → See all settings).
- Click the Filters and Blocked Addresses tab.
- Scroll to the Blocked Addresses section.
- Find the address and click Unblock.
You can also unblock by opening a message from that sender in your Spam folder and selecting "Unblock" from the same three-dot menu.
Blocking vs. Other Gmail Options: What's the Difference?
Gmail offers a few related tools that often get confused with blocking. Understanding each one helps you pick the right approach.
| Feature | What It Does | Best For |
|---|---|---|
| Block Sender | Routes emails to Spam automatically | Unwanted personal contacts, persistent senders |
| Unsubscribe | Removes you from a mailing list | Marketing emails, newsletters |
| Filter + Delete | Auto-deletes or labels emails by rules | High-volume senders, pattern-based filtering |
| Report Spam | Flags message as spam, moves to Spam folder | One-off junk mail |
| Report Phishing | Alerts Google to a potential phishing attempt | Suspicious or deceptive emails |
Blocking is most useful when you have a specific person or address you don't want to hear from again. Filters are more powerful for managing categories of email — for example, automatically archiving or deleting anything from a particular domain.
Creating Filters for More Advanced Control
If you want to go beyond blocking a single address — say, you want to block an entire domain or set up rules for multiple senders — Gmail Filters are the right tool.
To create a filter:
- Open Gmail Settings → See all settings → Filters and Blocked Addresses.
- Click Create a new filter.
- Enter the sender's address or domain in the From field (e.g.,
*@spammydomain.comto catch an entire domain). - Click Create filter.
- Choose what to do: Delete it, Skip the Inbox, Mark as read, or a combination.
Filters give you granular control that the basic block feature doesn't. They also don't have an obvious cap, unlike the blocked addresses list, which Google has historically limited to a few hundred entries per account.
Variables That Affect How You Should Approach This 🛠️
The "right" method isn't the same for everyone. A few factors shift the calculus significantly:
- Volume of unwanted mail: One persistent ex-friend vs. a flood of promotional emails calls for very different tools.
- Whether you need a record: Blocking routes to Spam (retained for 30 days). Filters can permanently delete. If there's any legal or professional reason to keep records, auto-delete may not be appropriate.
- Whether it's a real person or automated mail: Automated marketing emails almost always include an unsubscribe link — and using it is often more effective than blocking. Blocking a legitimate marketing list may not stop all messages if the sender uses multiple addresses.
- Your Gmail account type: Personal Gmail accounts and Google Workspace (business) accounts both support blocking, but admins on Workspace accounts may have additional controls — or restrictions — on what individual users can configure.
- Access method: Some features in Gmail's web interface aren't fully mirrored in the mobile app or third-party email clients that connect via IMAP. If you use Gmail through Outlook or Apple Mail, blocks set in Gmail's web interface still apply server-side, but the client-side experience may differ.
How aggressively you block, filter, or unsubscribe — and which combination of those tools makes sense — depends on your specific inbox, your tolerance for maintenance, and whether you're managing a personal account or a professional one.
