Some people view their email addresses as personal information, and they prefer not to give it away so easily. Thus, when signing up for mailing lists, they may use throwaway addresses. This is often the case when brands offer a discount code for those that sign up to their newsletter.

Such an action can be detrimental to your business. Disposable email addresses are one of the top frustrating factors for marketers and for those that are trying to build an organic list or an active database. However, throwaway addresses are here to stay as people are trying to avoid receiving unwanted emails.

This article will discuss what a disposable email is, why people use them, how to avoid them, and how to help yourself in a situation where you find them.

What Is a Disposable Email Address?

A disposable email address is often referred to as throwaway or burner addresses. The reason for this is because they are temporary and usually not used more than once or twice. Some people use them because they do not want to reveal their personal or business email address. They are not illegal, so visitors have no limitations on how many such email addresses they can create.

Unfortunately, numerous websites allow users to make such an email address. For example, Throwaway Mail is as simple as its name. On the homepage, you enter the address you want, and the address will remain active until the tab is refreshed or closed. Hence, the user decides for how long they want that particular email address. In the majority of cases, the addresses get deleted after a few minutes.

Furthermore, another website that is frequently used is 10MinuteMail. Its longevity is right in its name. Once you create the email address, it will expire in 10 minutes. Of course, if you require even more time, you have the option to expand with a further 10.

Such an action works well for those that are afraid of receiving unwanted emails. However, the problem with the majority of such websites is that the emails that people receive are public. This means that everyone who visits them can see what one has received.

Semi-Permanent Email Addresses

Such email addresses are similar to temporary ones to an extent. The similarity is that they are publicly accessible and not password-protected. This means that again, others can see what emails you have received.

Websites such as Maildrop will automatically suggest an email address for you, and you can decide if it is suitable or not. Even though they do this, you don’t have to worry about sharing an address with someone else as the algorithm prevents such action.

Semi-Permanent Email Addresses

Such email addresses are different from the temporary ones because you decide when you get rid of them. So, it will not delete itself after you close the tab. If you completely forget about the disposable address, the website will remove it for you.

Types of Disposable Email Addresses

These addresses are genuine and are usually hosted by reliable email providers such as Gmail, Hotmail, or Yahoo! Mail. Every campaign that gets sent will arrive in the user’s inbox if it hasn’t triggered the spam filters set by the providers. However, messages can be filtered to a folder that is outside of their primary inbox. Such an inbox will go on until the user decides to delete it. Some use aliases to track where the email was shared — for example,,

Such addresses are created with the sole purpose to forward messages to that particular account. In the majority of cases, they have a different domain than what the account holder is used to. The bad news for you is the fact that you don’t know for sure if the email that you’re sending goes towards the main account or the forwarding address. If you have a good sender reputation, the messages will arrive in the inbox, but your open and engagement rates will be affected.

Temporary or semi-permanent addresses will affect your sender reputation because they are a one-time address. Your sender rates will be affected because emails will bounce after the first send. As well as, they represent no value on your list.

Often, people use them because they do not value your brand, or they want the discount code that you offer for newbies. In addition to this, they can also use it to:

• Enter a contest

• Download content

• Sign up for spam purposes

Some of your competitors can do this right now to affect your sender reputation. Those that want to hide their identities do not care for the business’s wellbeing. Hence, some marketers call them “dark mail.”

How to Avoid receiving Disposable Addresses in your mailing list

Build Trust

Not so long ago, people didn’t want to sign up with their real email because their address would get sold to the highest bidder, often referred to as “third-party.” Even though now this is no longer the case, people are still apprehensive giving their most frequently used email addresses.

The solution to this problem will be to tell people straight. Give them an incentive and let them know how the data will be kept safe in your hands by letting them know your company's privacy policy.

Limit Incentives

If you currently offer an incentive for the newbies, you should know that some people bite more than they can chew. Hence, they will sign up with more than one email to ensure that they can profit as much as they can from your generosity.

Even if you have the opt-in form, some websites allow users to keep the throwaway email for more than 10 minutes. Therefore, the best solution would be to give the newbies a follow-up email within 30 minutes or even the next day.

It’s unlikely that someone will keep the tab unrefreshed for 24 hours. Thus, you’re encouraging people to sign up with their primary email addresses.

Show Them What they are Missing

Some people don’t see the value in the brand, so they justify their actions with it. Once they’ve received what they wanted, they will ignore every campaign you send to them. This is why it’s essential to provide them with information regarding the benefits that they will get once they sign up to the list.

You should answer their question, “What’s in it for me?” By letting them know that you will never misuse their information and by showing them what’s missing if they don’t sign up, they will think twice about closing the tab or using a throwaway address.
