We all receive emails in our inbox every day that we don’t want. This guide will show you how to block an email address from unwanted senders through various email providers including Gmail, Yahoo, Outlook, and iCloud Mail. It will also explain how you can use Leave Me Alone’s email unsubscription and Inbox Shield tools to help you manage your inbox and control who can contact you.

When To Unsubscribe And When To Block?

While unsubscribing and blocking emails should give you the same end result, they serve different purposes. Blocking emails aims to stop specific senders by diverting their messages straight into your SPAM or Trash folders. However, if you’re looking to stop a newsletter sender from reaching you, blocking them won’t remove you from their mailing list; the emails just won’t reach your inbox anymore.

Whenever unwanted mail involves a mailing list subscription, you should be able to easily unsubscribe by following an unsubscribe link in the email. The Leave Me Alone unsubscribe tool is a handy service that enables you to easily unsubscribe from multiple email senders/mailing lists under one dashboard, saving time, especially when dealing with numerous subscription emails you’d like to clear out.

What happens when you block an email address?

The action taken with emails from your blocked senders depends on the email provider. Most email providers will automatically filter the blocked mail directly into your SPAM or Trash folders. It will not unsubscribe you from a mailing list.

Where do blocked emails go?

You will find your blocked mail in your SPAM or Trash folder depending on the email provider. However, remember that these messages will often be stored for a finite period (often between 14-30 days) before being automatically deleted.

How to unblock an email address?

Every email provider gives you the option to unblock an email address you have accidentally blocked. Instructions are provided above on how to unblock senders depending on the platform.

Why do I still receive emails from a blocked sender?

Some SPAM senders will use multiple email addresses that look similar to reach you, which might be why you are still receiving emails from them. By identifying the root domain of the sender and blocking that domain, you should be able to block all future correspondence.
