Yes, You Need a Disposable Email Address!

Category: Spam

Have you ever visited a website that demanded your email address to make a purchase, create an account or gain access to information? I'm sure you have, and in some cases you've probably done so hesitantly, thinking that you might be opening your inbox to a flood of spam. A disposable email address provides a handy solution to this problem. Read on to learn more...

Fight Spam With a Disposable Email Address

It seems everyone wants my email address: Facebook, my bank, my accountant, even the tomato vendor at the farmer’s market. It’s no wonder my spam filter is so busy, but I do wonder which of the many entities that have my email address gave, sold, or lost it to spammers. Disposable email addresses can help you tell who the untrustworthy contacts are.

A disposable email address is a temporary or anonymous email address that can forward mail to your permanent address. Ideally, any replies you send are relayed back through the disposable email address to the original sender, who never learns your permanent address. If unwanted emails suddenly start arriving through the disposable email address, you can stop it by deleting or filtering that address.

You can have one disposable email address for every entity that requires an email address, if you like. Then if spam starts coming from a given disposable email address, you can be pretty certain who’s responsible.

Disposable Email Addresses

It’s possible that a spammer just randomly generated an email address that matched one of your disposable email addresss, but it’s MUCH more likely that the entity to which you gave the disposable email address shared it, willingly or by theft. Having narrowed down the security leak to one entity, you can investigate and decide whether to give that entity another disposable email address or steer clear of it.

Plus Addressing and Other Options

There are several ways to create disposable email addresss on your own. Some are free, and some are a lot more work than others. My favorite is “plus addressing” with Gmail, which lets me make up a disposable email address on the spot for whoever wants it. Here is how plus addressing works, and some limitations on this technique.

Let's say your email address is Add a “+” sign and any string of characters between “whatever” and the @ symbol, for example, Now give that address to your online Chase Bank account. Repeat the process for Facebook, newsletter subscriptions, online stores, websites with "squeeze pages" that make you supply an address to continue, etc. All mail sent to your plus addresses will go to your inbox.

If you start getting unwanted emails at the plus address, just create a Gmail filter to send them to the Trash. For extra points, create a filter to funnel the mail from each plus address to its own Gmail folder. Just keep in mind, this trick works well for automated systems that send to you, but can be defeated by humans who are clever enough to remove the "plus" portion of the address. Also, when you reply to a message sent to one of your plus addresses, the From line will be your standard Gmail reply address, not the plus address. Not all websites will accept a Gmail address with a plus sign, but it works most of the time.

The plus sign trick also works with (formerly Hotmail) but Yahoo uses minus signs and makes the process a bit more difficult. See this page on Disposable Addresses in Yahoo to learn how it works.

Another option, if you have your own domain and receive email there, is to create email aliases. That's outside the scope of this article, but your web host or domain registrar can provide details on whether that feature is offered, and how to set it up.

Disposable Email Address Services

Yes, it is a lot of work to set up and maintain disposable addresses for all the entities with which you communicate via email. Fortunately, there are numerous disposable email address services that handle most of the heavy lifting for you. Here are some of the established and reputable disposable email address service providers:

Sneakemail bills itself as "The Original Disposable Email Address Company," and offers to hide your address from spammers and others you'd rather not be dealing with. If someone wants your email address, and you have qualms about providing it, login to Sneakemail and create a new address. If mail is sent to your Sneakemail address, it will be forwarded to your real address. Sneakemail also creates an alias for the sender of your incoming messages, so if you reply, only your Sneakemail address will be exposed to the recipient. Sneakemail is free for the first month, and then $2/month thereafter.

Trashmail receives emails and forwards them to your permanent address. When you set up a disposable email address on Trashmail, you can set a limit on the number of emails that can be received or the number of days that may pass before the disposable email address expires. Your disposable email address can be a username of your choosing on, or 10 other domain names (,,,,,,,,, An optional Chrome browser addon makes it more convenient to use the service. Basic service is free, but if you want more than 300 addresses, unlimited forwarding or a permanent address, Trashmail Plus can be purchased for US$12.99/year.

Mailinator: There's no registration, just make up a username and give out the address That address will be created on Mailinator’s server when someone sends mail to it. Just be aware that Mailinator inboxes are public, so anyone can read mail sent to that address (but only if they know the username). After a few hours, all mail is deleted. So Mailinator is a free, easy, on-the-fly disposable email address service useful for online forums and other sites that require one-time registration. You just go to to respond to the “confirmation” email sent by the forum or site.

At Guerrilla Mail, you can choose a username and one of ten domain names for your free temporary email address. (My favorite is Like Mailinator, messages are public, and are held for one hour before they are deleted. One nice feature is that you can scramble your email address, to make it harder to guess. GuerrillaMail also lets you reply to incoming messages. There's also a free Guerrilla Mail app for mobile phones, on the Google Play store.

10minutemail: Load up this site, and you immediately get a free random email address that vanishes after 10 minutes. You can get a 10-minute extension if you need it. Just refresh the page to see any incoming messages for your temporary address. View, delete or reply to any new messages that appear.

I agree with Bob that disposable addresses are a must for many, if not all folk.

I don't find Yahoo disposable addresses difficult to use at all, and unlike G-Mail your base name is something you choose and need have no similarity to your real address. You give and set the disposable up in your account. You can close it down whenever you want or need to. And can actually restart it too if you want. The only thing that is permanent is the base name portion of the disposable address.

As an aside, I have NEVER, EVER used my "real" address, yet a few years ago I started to receive spam on it. Not possible they said at the phone company, who use the Yahoo mail system to provide our email. I now realize it was likely because of the hacks at Yahoo ... maybe companies need to listen to customers who tell them something is happening, even though it is thought to be "impossible".

I use SpamGourmet, you do need to register then you create temporary addresses that you can limit to the number of emails that get forwarded before the system starts trashing them.

Basically how it works is that you create an account, don't use your real name, e.g. user123 on the site.

You can then create a list of words to use and set the options to limit to list but this is optional.e.g. raven

Now you can create addresses of the form and the originator can send 5 emails, in this example which are forwarded to your real email before eating anything else.

The system also allows replies to route via spamgourmet and many other features. The site is really ugly but it does work.

Hey, Bob! GMail also has other options. Gmail is 'dot-blind' and will ignore any dot in your email address before @ sign. "" can be ""
Other examples: assuming your email address is, all email directed to , , and any other dot-variant addresses will be delivered to your gmail inbox.

I'll second the interface is probably back from 1980's but I use it nearly every day. Once you start using it you'll see how it can cut back back dramatically on sites selling your email info...because the spam will get eaten by this service. :)

I like the Bloody Vikings! Firefox addon. It gives you several choices of throwaway emails. I wouldn't use it for banking, but those other sites which want your email for spam are easily defeated.

It seems to me that Sneakemail is behind the times. Not only you need to go to the site to create an alias every time you need one, but you also need to specify your redirection address each and every time you create an alias ! (At least if the tutorial is to be believed.)

Most people will only need one redirection address, and it will always be the same.

Also, it's expensive, at 20 $ with no free plan. For 30 $ per year, you can buy a full mail service from the reputable Australian provider Fast Mail, which will include 600 aliases to use as disposable email addresses (and you'll avoid all Google-related spying). Fast Mail basic plan used to cost only 10$/year a while ago...

In this day and age, I wouldn't use one of those services where your mail is available for everyone to see. While this might have been acceptable several years ago, the threat level from hackers has gone up several notches.

a dash or a plus sign makes it pretty obvious what it is. i imagine it won't be long before they'll refuse to accept them. get a web site and you'll have dozens of email addresses if you want them...

The + sign isn't accepted at any site I have tried it on and hasn't been for years now. Gmail's spam filter is pretty darn good and I almost never get any. Can't remember when the last time was. They do get a few false positives, but even those are advertising from sites I registered on 99%+ of the time.

Let us not be too smitten with such tricks like “plus addressing” with gMail (etc.)
I am willing to bet that the spammerZ are always busy little beavers and they have figured this little game out a bit.
If 'aliasing' is not an option (yet worth every penny), then customizing the +addressing is a must:
In your '' example, it may be a better option to ALWAYS start creating these 'plus addresses’ with a couple of known characters as the FIRST few. For example, add "A17" just before 'plus' so that you are one step ahead of them (=>’’).
This makes spam detection/filtering much easier because if the address does not start with this 3-character code, then you are assured that you did not create it but a spammer did.
Maybe then, at the start of 2018 (if email still exists) your customized code may become “B18” or sumsuch!
[Sorry for the length.]

Yahoo allows you to create temporary e mail addresses. If I get too much spam on that address, I delete it, and make another disposable address. It works for me well.

I'm surprised you didn't mention the great-grand-daddy of them all - Spamgourmet. I've been using this facility for years. Very useful

I use disposable mail for various sites. The problem I an starting to see is many sites are on to the disposable mail and no longer accept disposable addresses. Seems to be a cat and mouse game to keep up.

Now another option if you own your own domain is create and delete address or alias as needed. I typically would create an address like "" if signing up with Starbucks. This way you see who is selling your e-mail address.

My favorite is Blur ( because it's free and it integrates into my browser (Firefox) and also works with Android and iOS phones. So when I come across a website that has an email field, it pops up my registered email and a new masked email so I can choose which I want to use. It also can mask credit cards and phone numbers, can eliminate web tracking, and auto-fill many fields like other password managers. Some of the functions are not free, but the ones I use (masking email addresses and eliminating web tracking) are free.

I ave an email address associated with the ISP I use, and am VERY selective in who I provide my email address to.
The ESP also has spam filters to cut down unsolicited emails.
As a result I don't really have a problem with unsolicited emails.

I've thought about trying to use a disposable email address and being able to identify to which entity you gave any particular email addie would definitely help pin down which one sold or gave away your details. But other than deleting that addie, thereby dropping your membership to that website, there seems no other benefit in going to all that trouble?

So I came to the conclusion that it probably wasn't worth all the bother to try and create a disposable addie that each target website would accept, when marking emails as spam and getting them automatically bounced, is so easy to do ...

And quite frankly, if a website will not allow me to even read their content without requiring my email address, I tend to be a bit suspicious anyway - and go elsewhere!

Tried this + and company name to the email address but it didn't work for my gmail account. Came up as an invalid email account.

I'll add one more. It works just like mailinator except it holds the mail for a longer period of time. I find mailinator deletes them to quickly.

Have to give a shout out to Blur by Abine. Amazing service allows blocking and deleting your fake address with a simple click within an email. On top of that, masked credit cards, phone number, and tracking protection. Great service and my "Go-To".

Sneakemail is not accepting new accounts right now. So I created a "Plus" account with Trashmail. To have this newsletter senr to the new address, I subscribed using the trashmail address, and this system would not accept that address. No explanation. Irony...
