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(new window)). 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.

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:

Sign up for Proton Unlimited to get Proton Mail, Proton Calendar, Proton Drive, Proton VPN(new window), 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.
