A better option to avoid spam email is to use temporary emails whenever possible.
Certain websites ask you for your email address for different activities. For entering a comment, for example, you have to provide your email ID. Likewise, when downloading some free e-book, they ask you for your email ID, so that they can send you the download link to this ID. This way, they can build up a data bank, so that contact you even after you got the book. If the site is good and the mail they send is useful it is fine, but what if they started spamming you? One of the benefits of masking an email address is that you can avoid spam using third-party browser extension.
How to Avoid Spam
Providing your email ID anywhere on the Internet invites spam. Though the companies or websites promise that they won’t sell your email address to anyone, they could share your email address with third parties. Some websites simply sell your email ID among other information to online marketing companies that too converts into more spam into your Inbox. For example, you register for a newsletter with a reputed website and start receiving promotional emails from unknown parties, you may wonder how the unknown party got your email ID!
Though there are many spam filters in place, they may or may not help you. Some of them come with an Unsubscribe option but, again, they may or may not help. A service like Unroll.me can then help.
The best way to avoid spam is to mask your email ID while providing it to websites. Even better is to use temporary emails. Temporary emails last for a definite period of time and expire afterwards. They are perfect for things like receiving links for e-books, etc., and to avoid the spam that follows later.
Masking email address
You will need a third-party browser extension for masking your email address. One example of email masking is MaskMe and Blur from Abine. The extension comes both free and paid. In the free version, it masks only the email addresses. The paid version goes a step ahead to mask phone numbers and credit card numbers.
MaskMe is available for Firefox and for Chrome. It is however no longer being updated. Its developers have developed a new addon called called Blur, which does this and more. Blur too is available for Chrome as well for Firefox.
Using an extension, when you encounter a field asking for email ID, you will get option to mask the email address. If you choose that, you get to enter an email mask (something like a fake ID) instead of real email ID. Mail sent to the masked email ID will be forwarded to your real email ID. You can decide which ones to keep and which ones to delete. That is, if you start receiving promotional email or something similar from a third party, you can set it to be deleted automatically.
Masking works best only in browsers, as email clients will download or sync all email. With email clients, you can set up filters and rules to check the incoming email and delete them if they are spam. There is probability of losing important email if you are not very careful when creating rules in email clients.
As evident from the name, temporary emails are valid only for a certain period of time – like, 10 minutes or half an hour. Such email IDs can be used when there is need for corresponding only once. For example, if you need to give them an email ID to obtain a download link for something, you can quickly create a temporary email and use it instead of your real email ID. Once you receive the link and the email ID expires, any further emails sent to it will bounce. That way, you will be saved from spam.
This explains the benefits of masking an email address and using temporary email IDs. It depends on circumstances whether to use temporary emails or to go for masking. You can temporary email only for a limited correspondence. In case of masking, you will keep on receiving mail, but you will have options to directly delete the emails using third-party browser extensions.
