Nobody wants to deal with dozens of spam messages flooding their inbox. Thankfully, most email services allow users to restrict specific addresses, effectively blocking unwanted content with just a few clicks. This article will explore the related procedures across various email providers, so keep reading to learn more.

So, can you block an email address?

You can easily add spammers or particular senders to your block list. This option helps keep your inbox free from junk mail. All the client needs to do is follow the step-by-step blocking instructions below. Each service provider has its own guidelines, so be careful.

The blocking procedure involves establishing filters or rules with defined criteria such as keywords and characteristics. This step is essential for configuring automatic redirection of incoming emails based on selected parameters. Consequently, emails will be either moved to designated folders, marked as spam, or bounced. Any particular blocking can be temporary or permanent.

What's the difference between unsubscribe and block

There are two primary approaches to getting rid of unwanted messages: opting out, aka unsubscribing, and blocking. These methods work differently and are designed for different situations.

The mailbox owner can unsubscribe from email newsletters or a particular source to stop receiving messages. At the end of the email, you can usually find the "Unsubscribe" link and click it to get removed from the mailing list, preventing future disturbances. However, this method relies on the good will of the sender and will only work if they are following the rules of mass mailing.

Another way to deal with unsolicited messages and junk mail is blocking. This feature prevents receiving emails from specific senders by your mailbox service. After this, any unwanted emails will end up in the spam folder or be bounced back by the mail provider.

It is advised to use the former method if you have previously opted to receive messages from this sender but just don’t need them anymore. The same goes for those cases where you may have forgotten about your previous consent but the message seems to be sent in good will. However, if the message is clearly and undoubtedly unsolicited, do not hesitate to block it: this will also help protect other mail users from similar unwanted emails.

How to block and unblock an email address in Gmail

Gmail, an email service run by Google, stands out for its intelligent email sorting capabilities. It efficiently organizes messages to maintain an orderly inbox. While junk mail is promptly directed to the spam folder, unsolicited emails still may occasionally slip through.

Blocking the sender emerges as the most reliable action to staunch unwanted email flow. Once a sender is blocked, their subsequent emails are quietly diverted to the spam folder. Here's a simple guide:

  • Open your Gmail account from your preferred device, be it a computer or mobile phone.
  • Identify and open the offending email.
  • Click on the More options button, depicted by three dots adjacent to the reply arrow.
  • From the ensuing dropdown menu, choose "Block [sender's name]". Confirm your choice in the popup "Block this address". From now on, all future emails from the banished sender will go to Spam.

For managing your blacklist, follow these instructions:

  • Access Settings by clicking the gear icon.
  • Opt for "See all settings" from the dropdown menu.
  • Proceed to "Filters and Blocked Addresses" to modify your block list.

Blocking "unwanted correspondents" not only aids in decluttering the inbox but also provides a more seamless and gratifying email experience. If you decide to unblock the correspondent, just follow the same steps, but instead of selecting "Block," click "Unblock."

Frequently asked questions

Is there an easy way to stop someone from sending me emails?

One of the simplest methods to prevent someone from emailing you is to find an email from that particular sender in your inbox, then navigate to email settings and opt for the "Block" feature.

Why am I getting emails from a sender I've blocked?

Blocking does not guarantee complete prevention of receiving emails from those addresses. Double-check your settings: you may have restricted the wrong sender or misspelled it. Also, the message could bypass the block feature if it was sent via CC (Carbon Copy) or BCC (Blind Carbon Copy). Finally, the offender might have just used another sender address you haven’t blocked yet.

Do emails bounce back to the sender if I've blocked them?

Blocked emails typically don't bounce back to the sender. Instead, they're redirected to the recipient's spam folder or deleted without notification. While some email services offer return notifications, it's not a standard feature.

How do you notify senders that they've been blocked?

There's no way to do that directly. When senders are included in the block list, they typically don't receive any notifications. They might only realize they're blocked if they notice a lack of activity on their emails.

How can I unblock emails?

Head to your email settings, locate the blocked sender's section, choose the addresses you wish to unblock and remove them from the block list.
