Block emails FAQs
Why block emails?
You may want to block emails from specific senders or whole domains (@domain-name.com) for various reasons. Here’s why.
Beat spam
Unsolicited and unwanted emails, also known as spam, are annoying and can contain fraudulent or malicious software (malware(nieuw venster)). Blocking individual senders or domains that send spam is one way to stop it.
Prevent phishing
Phishing emails try to trick you into revealing sensitive data or downloading malware, often leading to identity theft, credit card fraud, or other cybercrime. Blocking suspicious emails can help protect you from falling victim.
Block abuse
If you receive abusive or threatening messages, blocking the sender can provide relief. Most email providers allow you to automatically direct emails from certain senders to your spam folder or block them altogether by deleting them.
Stop marketing
You may be swamped by marketing emails or no longer want to receive that weekly newsletter. Blocking the sender or unsubscribing can help reduce junk in your mailbox.
Take control
Has the constant influx of countless messages made your inbox unmanageable? Blocking, filtering, or unsubscribing from emails can help you take back control and see only the messages you want.
Block, filter, or unsubscribe?
How you stop unwanted emails from reaching your inbox depends on your situation and preferences.
Block
Blocking emails means setting up a filter or rule so that messages from a particular sender or domain are sent straight to your spam folder or trash. Unlike unsubscribing, senders can’t see that you’ve blocked them. So blocking is better for your privacy and for dealing with suspicious messages or senders you don’t trust.
Filter
Filtering means creating rules so incoming messages are sorted based on certain criteria. For example, you can sort all sports newsletters into a “Sport” folder. Filtering emails can help you organize your incoming emails and file away unwanted or low-priority messages.
Unsubscribe
Unsubscribing is typically used for newsletters or marketing emails that you no longer want to receive. If the message is legitimate, it should contain an “unsubscribe” link. But before clicking, check for signs of phishing. If the message looks suspicious, block the sender instead to protect your privacy and security.

How to block emails on Thunderbird
Unlike most other desktop email clients, Thunderbird doesn’t give you the option to block messages from specific senders or domains. But you can create a filter and set up a blocked senders list as follows:
- Open the Thunderbird app on your computer (PC or Mac).
- Open a message from the sender you want to block.
- Right-click the sender’s address and select Create Filter From.
- Type in a filter name, for example, Block list. The address you want to block will be automatically filled in.
- Under Perform these actions, choose either Delete Message or Set Junk Status to … Junk.
- Select OK to save the filter.
Once you’ve created your Block list filter, the next time you want to block someone, you can add their address by clicking the plus button (+).
If you want to block all messages from a domain (for example, @domain-name.com), you can add the domain name instead of the email address.
To unblock senders or domains:
- Go to the Tools menu at the top and select Message Filters.
- Select Block list (or the name you’ve given your blocked senders filter) and click Edit.
- Click the minus sign (–) next to the sender you want to unblock.
Note that Thunderbird message filters are account-specific, so when you set up a filter, make sure you’re setting it up for the correct account.
Other ways to block emails
If you want to protect your privacy but don’t want to stop receiving emails from a sender, you can use email aliases to hide your personal email address.
When you sign up for a new online account or newsletter, you can create a unique email alias that instantly forwards all incoming emails to your personal email address.
If you ever want to stop receiving unwanted emails from a sender, you simply deactivate that alias. At no point is your real email address revealed.
We’ve designed Proton Mail to give you maximum flexibility to filter messages and generate aliases for your privacy and security:
- Spam, block, and allow lists let you manage blocked senders and spam and ensure you receive important emails.
- Custom filters and Sieve filters give you granular control over incoming mail to block and sort senders.
- The Unsubscribe button lets you unsubscribe to newsletters easily, and link confirmation gives you an extra layer of protection when you click on unsubscribe links.
- Proton Pass, our encrypted online identity manager, lets you generate hide-my-email aliases to protect your personal email address.
Sign up for Proton Unlimited to get Proton Mail, Proton Calendar, Proton Drive, Proton VPN(nieuw venster), and Proton Pass with unlimited hide-my-email aliases.

Block emails FAQs
What happens when you block a sender?
When you block a sender, any messages they send you in the future go straight into your spam folder or are deleted, depending on the service you use and the options you choose. Blocking a sender doesn’t prevent them from sending you emails.
Do senders know you’ve blocked them?
No, the sender won’t receive any notification that you’ve blocked them. But they may guess they’re on your block list and try changing their email address to reach you.
Can you block any email from an organization or just specific senders?
With most email services, you can block emails from individual senders or domain names (@example-domain.com). By blocking an organization’s domain name, you can stop emails from anyone at that organization.
Can you block emails from someone permanently?
If you block an email address or domain name, all future emails from that person or domain will either go to your spam folder or be deleted, depending on the service you use and the options you choose. However, a determined sender can always change their email address to evade your block.
